Abstract:

Predicting and enhancing the life-cycle of Lithium-ion battery packs has been the subject of studies toward the large-scale use of storage systems to store the electrical energy in the time of fluctutation and unpredictable behaviour of wind renewable . Battery pack is a group of cells are placed in a parallel, series or matrix form to provide the required power. Life cycle prediction of a single cell is challenging due to the complexity of electrochemical reactions, thermal vraiablity and the formation of SEI layers. Cell interconnections make the prediction more challenging as the electrical dynamics and thermal characteristics of each cell is different from the others. This introduces random variability where the aging of a single cell propagates and reduce the life of the whole pack. This works investigates the use of accurate electro-chemical modelling and wireless sensor/antenna system in real-time estimation of the critical cell parameters, i.e. state-of-the-charge (SOH), state-of-health (SoH), internal resistance, and temprature variation. The integrated system will significantly supress the aging propagation and enhance the life-time of

Abstract:

Sources of energy which are used on large scale are termed as conventional sources of energy where as the energy sources which are used on small scale are called as non- conventional sources of energy. Green energy produced from non conventional sources include Small hydro power, wind power, solar energy, geothermal and energy produced from bio fuel.

Increase in land and air pollution during the conversion of energy sources of fossil fuel such as oil, coal and natural gas have their adverse effects on environment and ecology. Depleting quality of these sources raise the question of sustainability in the long run there by compelled humanity to go in search of the other alternatives. In this context, the non conventional sources of energy have attracted the global attentions and evoked interest among policy makers as a viable option for sustainable development.

Out of 120 crore population of India, 46 % of them leave in rural and far flange areas and survive on Kerosene ,wood for fire and cooking  or nonconventional sources of energy as their primary sources .

It is hurting to know that India loses nearly dollars 18 Billion (20) annually in power sector which is sufficient to provide 490 Million free of electricity for a year through micro greed.

As the world moves to cleaner energy sources and water becomes increasingly valuable commodity in many regions, it will influence the choice of energy options.

 Electricity production accounts for more than 50 % Global Warming emission with the majority generated by coal fired power plants in the world. Natural gas power plants produce more than 10 % total emission in the world. In contrast to this most renewable energy and nonconventional sources produce very little global warming effects.

In these article efforts has been made to project the overall scenario of non conventional sources of energy and their utility in remote areas where conventional energy cannot reach. The energy produced by small hydro, solar and wind etc can find its place to cater to the needs of people living in rural areas .The

Article also refers the research and innovative measures required to be under taken  to supply  power to the masses in rural areas and  it also high lights the challenges faced to supply energy to far flanged areas.

Abstract:

The development, construction and operation of a wind farm is a complex and long process involving many different agents. Disputes arising from interpretations of contract clauses are usually lengthy and costly. Unprecise definition of boundaries (both physical as well as contractual) is also a source for delays and extra costs. On the other hand, blockchain technology provides the framework under which a set of data can be irrevocably and undisputably arranged in a way that all parties can share it and add elements to the blockchain in a secure way which is validated by the system itself. One of the uses of blockchain is the implementation of smart contracts witch enable the execution of certain clauses without the need of a third party external assessment. Some of the contracts are exceedingly complex to try to reduce them to a set of simple rules, but the development of smart contracts for specific aspects can be of great help to increase the efficiency of a project. In this paper, we analyse the different phases of a wind farm project (from predevelopment works to operation and maintenance) and suggest smart contracts for those elements that can be singled out as suitable for this technology. We find that, at some stages, a formal input from a third party may be needed and suggests ways to automatize this. This hybrid character is not present, however, for the operation of the wind farm, where a sensible choice of sensors may confirm a fully automated system.

Abstract:

Direct ethanol fuel cells (DEFC), which promise to be a clean and efficient energy production technology, have recently attracted worldwide attention, primarily because ethanol is a carbon-neutral, sustainable fuel and possesses many unique physicochemical properties including high energy density and ease of transportation, storage as well as handling. However, conventional DEFCs that use acid proton exchange membranes (PEM) and precious metal catalysts result in rather low performance. In our research, we used alkaline anion exchange membranes (AEM) as the ion conductor in DEFCs. The change from the acid membrane to an alkaline one led to a significant performance boost: the power density increases from 30 mW cm-2 to 90 mW cm -2 . In addition, we developed a novel hybrid DEFC system, which consists of an alkaline anode and an acid cathode. Our unique design results in a power density of 240 mW cm-2 . To further optimize and improve performance, we developed an integrated model for the fuel cell system. By doing so, the power density of DEFCs now is as high as 360 mW cm-2 . This high performance is attributed not only to the unique design, but also to the use of the integrated model.

Abstract:

Photovotiaics (PVs) integration to the distribution feeder is on the increase. The variability and uncertainty of the renewable energy (RE), however, can potentially cause a voltage deviation from the permissible limits and disruption of normal operation of voltage/VAr (VVAr) control devices.  This paper proposes a platform, in the operation timescale, to maintain voltage regulation and facilitates the smoother integration of renewable energy into the distribution feeder with PV energy sources. With the objective of improving system-wide voltage profile and minimal losses, the operation of VAr control devices and energy storage, is coordinated in the operational timescale.  A Genetic Algorithm (GA) based-optimization method is used to consider the optimum settings of the VAr control devices and the dispatch of energy storage. The effectiveness of the proposed method is validated through a time sequence analysis over a 24-hourly simulation period, applied to the IEEE  123 test feeder.  Test results depict clearly that the coordinated operation among the control devices, along with the energy storage, causes reduction in system losses and enhances system capability to maintain voltages within the statutory bounds under various penetration levels of PV energy sources.

Abstract:

Using Micro-Grid (MG) concept to enhance penetration of Distributed Generation (DG) has raised some technical challenges including stability and power quality issues. Therefore, such issues has been researched and investigated by many experts in recent years.

Power quality considerations are the most challenging tasks in MGs so that designing control strategy without power quality considerations can lead to instability of MG. Thus, stability and power quality are two relevant issues regarding the selection of control strategy in an MG.

 For this reason, this paper presents a review of control strategies and also investigates the effect of new approach on power quality and stability of MGs.

A new problem formulation is developed by employing a multi-objective function approach where the objectives include the fuel consumption cost, voltage stability index and the total voltage variation of MG. A hybrid optimization algorithm is proposed to solve the proposed problem by combing the HS and the GA. A new load flow formulation is derived to run the proposed optimization algorithm where the steady state frequency of system, reference frequency, reference voltage and droop coefficients of DGs, based on a droop controller, are considered as optimization variables. To find the best solution of non-dominated results, a fuzzy method is employed.

Abstract:

Flow over Darrieus type straight-bladed vertical axis wind turbine with NACA0021 is analyzed using ANSYS Fluent software. k-ω shear stress transport turbulence model is used for the two dimensional, unsteady simulations. Wind speed is taken as 9 m/s and the rotation of blades is modeled using the sliding mesh technique.

 The two-dimensional computational fluid dynamics model is validated with experimental results. The optimum tip speed ratio is achieved, giving the best overall performance.

 The effect of the tip speed ratio on the aerodynamic performance of the studied wind turbine in non stationary regime is discussed. Contours plot of the three-bladed Darrieus rotor are also presented and analyzed.

The present study shows that the tip speed ratio directly affects the aerodynamic efficiency and the torque production of the Darrieus type vertical axis wind turbine .

Abstract:

The Aerofoil Water Turbine (AWT) is a machine designed by ZHEN XIN TECHNOLOGY CO.,LTD. The AWT which intent to install on river is able to generate electricity by the motivation of water flow. However, the mechanical strength of the design is not robust enough that the prototype of the structure is not able to withstand the water flow and the machine is prone to break during the test process. Hence, we construct a CFD model in order to simulate the AWT on the river. After some simplification of the geometry, the selection of solution parameters and the setting of boundry condition. We developed several directions for ZHEN XIN TECHNOLOGY CO.,LTD to improve the AWT mechanical strength. The CFD model which we constructed include hydraulic analysis, fluid structure interaction (FSI) and structure analysis.

Abstract:

In recent years, the increasing penetration of Renewable Energy Systems (RESs) has made an impact on the operation of the electric power systems. In the grid integration of RESs, data acquisition systems and communications infrastructure are crucial technologies to maintain system economic efficiency and reliability. Since most of these generators are relatively small, dedicated communications investments for every generator are capital cost prohibitive. Combining real-time attack-resilient communications middleware with Internet of Things (IoTs) technologies allows for the use of existing infrastructure. In this talk, I will present our work in developing an intelligent communication middleware that utilizes the Quality of Experience (QoE) metrics to complement the conventional Quality of Service (QoS) evaluation. Furthermore, our middleware employs deep learning techniques to detect and defend against congestion attacks.

Abstract:

Wind energy is one of the fastest growing renewable energy sources in the world. Installed wind energy is 74.5 GW at the end of 2015, almost thirty-fold increase from 2000 where the installed wind energy is only 2.5 GW. However, most of these installed wind energy is produced by large scale wind turbines that requires an averaged wind speed of about 12 to 15 5 m/s. That requirement put a limit on the opportunities for using wind energy in many areas and locations around the world. As a result, research studies on the low speed wind turbines that can operate effectively at wind speed of 5 to 6 m/s have become increasingly common. In addition, non-traditional methods of deploying wind turbines, for example, using then by the roadside to generate electricity, have been studied more recently. In this presentation, current state-of-the-art research on the low speed wind turbines will be presented. Based on these research, future opportunities and challenges facing extensive deployment of low speed wind turbines will be explored and discussed.

Abstract:

Wind power is one of the most prevalent forms of renewable energy, second to only solar energy. The incumbent idea of extracting kinetic energy from surface wind currents, and converting this energy into electric energy is carried out by the combination of gear drives and an electrical generator. Using a suitable power electronic converter, this electricity may then be integrated into the grid directly, or may also function to supply power to a recharging station. This transition, coupled with the augment of global warming, particularly due to the combustion of fossil fuels to provide electricity, has resulted in multiple small scale installations of wind turbines.

Conventional aerodynamic schemes cannot be applied to rotor blades operating under low Reynolds number conditions as compared to those occurring under high Reynolds number conditions since certain unusual aerodynamic phenomena  predominate in the case of the former. This paper entails the design as well as experimental validation of a new class of airfoils for small horizontal axis wind turbines that are used in urban environments.

A common misconception with regard to selection of airfoils followed by subsequent design of rotor blades involves the use of NACA airfoils and other conventional high Reynolds number airfoils. The airfoil is designed in such a way so as to extract the energy from the wind shade region, which is practically unheard of in conventional wind rotor aerodynamics. The aerodynamics as well as the environmental impact have also been studied in depth.

She is also interested in distributed generation and its integration with the power system. She is a reviewer for JCR listed journals. She participated in realization of a few national or EU grants.

Abstract:

The development of renewable energy sources (RES) created some new possibilities for the electricity consumers. Consumers may now invest in the renewables and produce electricity and heat for their own needs. They may also sell the electricity surplus to the energy supplier. In such a way they may become prosumers. In some countries, the governments and local institutions offer subsidies to encourage consumers to invest in solar panels, photovoltaic, small wind or hydro generators. Such incentives increase consumers’ interest in this sector of the energy market. Moreover, consumers may also choose the energy supplier who offers green electricity tariffs or allows participation in green energy programs. The prospect seems optimistic, but research survey and pilot programs show a very low engagement and enrollment rates among consumers.

This presentation will focus on consumers’ energy behavior and their willingness  to  pay for RES. Social and psychological factors, that influence the adoption of RES will be discussed. Consumer engagement and acceptance of green energy are necessary to make the diffusion of these products possible and effective. Hence, following questions will be answered:

· How green energy (in particular: green electricity tariffs and small-scale generators) diffuse among the customers;
· What makes consumers adopt to the RES;
· What obstacles slow the diffusion and what factors may enhance the successful adoption;
· What are the main reasons of the intention-behavior gap among electricity consumers.

In conclusion some behavioral strategies that may help to speed up the diffusion of RES among consumers will be proposed.

Abstract:

Since the earliest direct concern for climate change in the Earth Summit, a UN Conference on Environment & Development (UNCED), Rio de Janeiro 1992, this high profile world Organisation has been seeing the writing on the wall…alarm bells of factual and potential global eco degradation and have consistently been spearheading initiatives to translate rhetoric and exhaustive debate into solid and effective commitments to redress the environmental deficiency brought about by over exploitation and abuse of the world’s natural resources and disregard of ecosystems, the lifeline of mankind’s own sustainable survival.

CFCs (now phased out under the Montreal Protocol) and Fossil fuels are making way to less polluting and more sustainable energy sources, reducing deleterious emissions. Heavy industry is progressively shifting to economically and viable alternative sustainable sources of energy from benevolent Mother Nature that has blessed us with unrivalled powers inherent in the Sun, Wind, and Oceans.

Nevertheless, challenges still lie in the way of achieving environmental targets, particularly by under-developed and developing countries which have to cope with climate change adaptation and the extraordinary financial capital to diversify and transform their economies to conform with this new exigency. Other challenges could also be overlooked or underestimated, even in implementing action plans involving renewable energy sources.

This Paper looks at and attempts to analyze, from the perspective of an observant, these challenges and also at viable practical measures to address them in efforts aimed at achieving sustainability based on win-win situations, with a particular focus on the local scenario.

Abstract:

Iran is a rich country in terms of wind energy, however, compared to most countries, little has been done on utilization of  renewable energies targeted. Potential energies such as high speed wind tunnels, solar energy, geothermal and valuable biomass sources of energy are at preliminary stages and their share of total power generation is still negligible and does not exceed 0.6%. Whereas, design and construction of wind farms is economically feasible due to reasonable price of equipment and abundance of cheap sources of renewable energy, SWOT analysis is conducted in order to unveil the reasons underlying the slow pace of development of wind farms in Iran. The analysis is intended to draw a roadmap and specify the nation's macro policies.

This SWOT analysis applies in wind farms and reveals the very fact that abundance of inexpensive fossil fuels constitutes one of the most decisive factors why wind farms remain undeveloped in Iran and instead priority is given to the thermal power plants which are both cheaper and more reliable compared to wind power generation. Significant factors considered by private investors and companies in the renewable energy sector, is the economic impediments and governing rules and  regulations. In this  study,  financing procedures and  change  of law  that  would  facilitate removal of the standing obstacles. The Middle Eastern possess fossil fuel resources but at the same time suffer from shortage of potable water as well as non-development of wind farms. This study in general can be useful and practical in these countries.

Abstract:

The study presents an improved control and operation for a doubly-fed induction generator (DFIG) based stand-alone wind energy system. Since there is no grid supply in stand-alone system, the output voltage has to be controlled in the constant amplitude and frequency even under unbalanced and nonlinear load conditions. This type of loads results in unbalance and distorted stator voltage and current with subsequent power quality degradation and electromagnetic torque pulsations of DFIGs. A new control strategy uses proportional-resonant controllers (PRC) is proposed for compensate the unbalance and harmonic distortion in the stator voltage and current of the DFIG. In this strategy, the load-side converter (LSC) is controlled for the purpose of fully reject the low-order harmonic components and the negative sequence of the stator voltage, this is achieved by employing PRC for the closed loop stator voltage regulation built in the stationary reference frame. As a result, symmetrical and sinusoidal AC voltage is applied to the stator terminal, which indicates that the rotor-side converter (RSC) can be still controlled with the traditional vector control strategy, to keep constant DC-link voltage. Simulation results are given and they show that the proposed control scheme can eliminate stator voltage and current harmonic of stand-alone DFIG effectively.

Abstract:

This study sets out to explore the implications of risks management on renewable energy project delivery, using wind energy projects as an area of interest. One of the major aims of project management is directed towards managing risks and thus an important concept in the field. Despite the progress in wind energy projects, they are subjected to numerous risks throughout their life-cycle. In this study, an exhaustive literature review was done on works of previous researchers complemented by an empirical quantitative survey using online questionnaires. This paper reports not only the critical analysis of the secondary data found in previous literatures, but also the primary data analysis obtained from the online survey. The study found that there is a need for improvement on how risks are communicated within wind project environment. The majority of those who responded to the survey indicated that risk associated factors such as; weather related (66%), economic (44%) and political risk (44%) present significantly impact to wind energy projects in their organizations. Other factors such as technical (26%), construction (36%) and environmental risk (28%) factors were viewed by the respondents as having moderate relevant to wind energy projects. A minority of the respondents (24%) indicated that operational risk associated factors also have minor association to wind farm projects. This finding supports the observation made by the Economist Intelligence Unit that; weather related risk is more significant for wind power projects than for other renewable energy technologies.

Abstract:

The aim of the presentation is to study the cheapest and sustainable way of renewable energy like wind for poverty alleviation in the developing countries of the world-South Asia.

Renewable Energy like wind is the basic need of our life. Look at the universe, no activity is found without the use of energy. You name any action you will find the force of energy behind it. As reported, Renewable Energy like wind, biomass, hydropower and solar are the cheapest source of electricity but the two main problems in the developing nations that is densely population of 5.87 billion amongst the world population of 7.84 billion and concentration on non-renewable energy like fossils, nuclear, coal etc which are very costly and beyond the power of developing nations although a great potential of renewable energy are available. According to World Bank, about 1.4 billon peoples lack electricity in the world and nearly one billion peoples particularly in the developing nations go to bed hungry each night. It means, renewable energy like wind is the main substitute of poverty and stimulates sustainable economic growth, create employment, increase agricultural and industry production as well as decreasing energy crises, which will reduce the poverty in developing nation. As per study, the role of International Energy Agency and International Renewable Energy Agency is very important but sustainability is still a big problem in the production of renewable energy. It is therefore proposed that an independent organization like “International Sustainable Energy Agency (ISEA)” should be established and renewable energy may be commercialized for poverty alleviation on a sustainable way in the developing country of the world-South Asia.

Abstract:

As one of the typical renewable energy sources, wind energy has experienced an immense growth with respect to both the turbine size and the market share, and led to a rapid development of the wind-power equipments. Owing to the highly volatile rough working conditions in real wind farms due to, e.g., wind gust, dust, corrosion and heavy yet unpredictable load, wind turbines are particularly prone to suffer failure and damage. Such damage can lead to a catastrophic failure of the entire wind turbine, and consequently heavy investment and productivity losses. Therefore, wind turbine condition monitoring and diagnosis become crucial. In this presentation, the development status of the wind energy all over the world, particularly in China, is briefly summarized. The research situations of the existing condition monitoring and fault diagnosis methods for the main failure components of wind turbines are then analyzed, such as gearboxes, bearings and blades. Finally, the problems to be solved and new development trend for wind power equipment monitoring and fault diagnosis are discussed.

Byeong Hee Chang has graduated from Korea Advanced Institute of Science and Technology (KAIST) in 1996 with PhD and worked in Korea Aerospace Reseach Institute (KARI). In KARI, he woked in wind tunnel design, construciton, and wind tunnel tests. Since 2016, he has been interested in this measurement technique with a roll-rotating ultrasonic anemometer for measuring wind speed and direction. In 2017, he did a validaton research with wind tunnel tests. 

Abstract:

Generally, wind turbine anemometers are installed on the nacelle behind wind turbine. So, they are in the wind turbine wake flow and the measured wind speed and direction are influenced by the wake and different from the freestream’s. Recently, the ROMO Wind developed a spinner anemometer of 3 single-axis ultrasonic sensors installed on the spinner for measuring undistured wind speed and direction. In this study, it was checked if a 3-axis ultrasonic anemometer could replace the 3 single-axis ultrasonic sensors as a spinner anemometer. The technique is based on the coordinate transform from the rotating sensor axis to the fixed coordinate for measuring wind speed and direction. Its validation tests were done with a roll-rotating test stand in the Korea Aerospace Reseach Institute (KARI) Low Speed Wind Tunnel. Even after the coordinate tranform, small rotating effect still remains in wind speed and direction. But, after one revolution of wind turbine, its mean values were converged to the test values within certain limits. The mean values were not much afftected by RPM (revolutions per minute), but affected by yaw angle and wind speed. The less yaw angle, the errors decrease. Upto 20° yaw angle, the errors of the mean values from the test values were less than double of the sensor own accuracy. At 10° yaw angle, the mean value errors were 2.0% RMS (root mean square) in wind speed and 1.7° in wind direction. But, in high yaw angle such as 60° or above, the mean value errors were drastically increased. So, in real application, if initial yaw angle is too large for this measuring technique, it could be reduced with a conventional nacell anemometer to within 20° and then it could be aligned more preciously with this technique including 3-axis ultrasonic anemometer installed on the spinner. This concept will be applied and checked to some operating wind turbines in real field in near future.

Abstract:

Sources of energy which are used on large scale are termed as conventional sources of energy where as the energy sources which are used on small scale are called as non-conventional sources of energy. Green energy produced from non-conventional sources include small hydro power, wind power, solar energy, geothermal and energy produced from biofuel. Increase in land and air pollution during the conversion of energy sources of fossil fuel such as oil, coal and natural gas have their adverse effects on environment and ecology. Depleting quality of these sources raise the question of sustainability in the long run thereby compelled humanity to go in search of the other alternatives. In this context, the non conventional sources of energy have attracted the global attentions and evoked interest among policy makers as a viable option for sustainable development. Out of 120 crore population of India, 46% of them live in rural and far flange areas and survive on kerosene, wood for fire and cooking or nonconventional sources of energy as their primary sources. It is hurting to know that India loses nearly dollars 18 billion annually in power sector which is sufficient to provide 490 million free of electricity for a year through micro greed. As the world moves to cleaner energy sources and water becomes increasingly valuable commodity in many regions, it will influence the choice of energy options. Electricity production accounts for more than 50% global warming emission with the majority generated by coal fired power plants in the world. Natural gas power plants produce more than 10% total emission in the world. In contrast to this most renewable energy and nonconventional sources produce very little global warming effects. In these article efforts has been made to project the overall scenario of non conventional sources of energy and their utility in remote areas where conventional energy cannot reach. The energy produced by small hydro, solar and wind etc can find its place to cater to the needs of people living in rural areas. The article also refers the research and innovative measures required to be under taken to supply power to the masses in rural areas and it also highlights the challenges faced to supply energy to far flanged areas.

Abstract:

Predicting and enhancing the life-cycle of lithium-ion battery packs has been the subject of studies towards the large-scale use of storage systems to store electrical energy during fluctuations and unpredictable behaviour of wind renewable. Battery pack is a group of cells which are placed in a parallel, series or matrix form to provide the required power. Life cycle prediction of a single cell is challenging due to the complexity of electrochemical reactions, thermal variability and the formation of SEI (solid electrolyte interphase) layers. Cell interconnections make the prediction more challenging as the electrical dynamics and thermal characteristics of each cell is different from the others. This work introduces random variability where the aging of a single cell propagates and reduces the life of the whole pack. The use of accurate electro-chemical modelling and wireless sensor/antenna system in real-time estimation of the critical cell parameters, i.e. state-of-the-charge (SOH), state-of-health (SoH), internal resistance, and temperature variation are investigated. The integrated system will significantly suppress the aging propagation and enhance the life-time of the pack.

Abstract:

Over the past few years, the University of Applied Sciences in Saarbrücken (htw saar) has carried out intensive research into small scale wind turbines, known as vertical axis wind turbine (VAWT). The well-known problem with the design of these types is that they did not start to run automatically. The VAWT must be electrically driven to start, which is due to design problems. The reason was identified by our team with numerical simulations of detachment behaviour at the blades. However, this can only be clarified by means of detailed measurement. In order to compare simulations, and investigate turbines behaviour more deeply, a new wind tunnel was constructed from scratch at htw saar. The so- called Göttinger design was chosen as type of construction, which means that air circulates inside. Dimensions of the tunnel are 12 m x 3.5 m x 2 m. Air is driven by a 7 kW rotor placed on upper side. Its nozzle diameter is about 1.6 x 1.6 meter. The VAWT can be placed in this position. Access points are positioned for temperature, pressure and velocity flow examinations. An additional heat absorber is used to control the air temperature. Two windows positioned inside the nozzle chamber can be used to visualize turbulence effects and enable the qualitative measurement of the spatial position and strength of compressible air vortices with a high-speed camera. There is currently no alternative test rig know for these kind of experiments. Thus, qualitative and quantitative behaviour of the VAWT can be examined. The investigation in the transonic wind tunnel, as well as the adjustment with simulations of the VAWT will be used for validation and further design development.

Abstract:

Synchronous belt is commonly used in the pitch system for wind turbines. It is a flexible pitch method and has a lot of advantages compared with hydraulic pitch system. Engineering methods is usually used to calculate the strength of synchronous belt, this is also the usual method in other industry. The disadvantage of this engineering method is that a lot of bearing capacity of the belt is wasted due to the large safety margin required by the methods. To fully utilize the capacity of synchronous belt, a more accuracy FEA (finite element analysis) method is developed to evaluate the strength of synchronous belt and estimate the remaining life time of belt on specific site conditions. This method could also be used in other industries with heavy and alternating loads.

Abstract:

Wearable technologies are driving current research efforts to self-powered electronics for which novel high-performance materials such as graphene and low-cost fabrication processes are highly sought. We demonstrate the integration of high-quality graphene films obtained from scalable water processing approaches in emerging applications for flexible and wearable electronics. We developed a novel method for the assembly of shear exfoliated graphene in water, comprising a direct treansfer process assisted by isopropyl alcohol evaporation. We demonstrate that graphene films can be easily transferred to any target substrate such as paper, flexible polymeric sheets and fibres, glass and Si substrates. By combining graphene as electrode and polydimethlysiloxane as active layer we demonstrate for the first time a flexible and transparent triboelectric nanogeneragor for haversting energy. Our results constitute a new step towards the realization of energy harvesting devices that could be integrated with a wide range of wearable and flexible technologies and opens new possibilities for the use of triboelectric nanogenerators in many applications such as electronic skin and wearable electronics.

Abstract:

Wind energy is one of the fastest growing renewable energy sources in the world. Installed wind energy is 74.5 GW at the end of 2015, almost thirty-fold increase from 2000 where the installed wind energy is only 2.5 GW. However, most of these installed wind energy is produced by large scale wind turbines that requires an averaged wind speed of about 12 to 15 5 m/s. That requirement put a limit on the opportunities for using wind energy in many areas and locations around the world. As a result, research studies on the low speed wind turbines that can operate effectively at wind speed of 5 to 6 m/s have become increasingly common. In addition, non-traditional methods of deploying wind turbines, for example, using them by the roadside to generate electricity, have been studied more recently. In this presentation, current state-of-the-art research on the low speed wind turbines will be presented. Based on these researches, future opportunities and challenges facing extensive deployment of low speed wind turbines will be explored and discussed.

Abstract:

Marine hydrokinetic (MHK) turbines have shown promise as a method for harvesting energy from natural waterways. However, excessive fabrication and assembly and high life-cycle costs often preclude implementation of these energy harvesting devices. As such, our research is focused on mitigation of the implementation challenges by development and demonstration of a novel low-cost, net shape fabricated single piece composite three-blade MHK turbine rotor to minimize both Capital Expenditures (CAPEX) and Operational Expenditures (OPEX) to enable cost of energy improvements. We were able achieve these cost reductions by leveraging our successfully demonstrated rapid prototyping protocol, underpinned by our team-based concurrent engineering approach, whereby we incorporate all key technology disciplines including materials, design and analysis, manufacturing, non-destructive inspection, and test and evaluation from rotor concept formulation through delivery of the single piece composite rotor prototype. Our presentation provides a summary of the three key emergent technologies associated with our prototype development and demonstration evolution: 1) design for turbine rotor manufacturability using computational fluid dynamics and finite element analysis; 2) single piece composite turbine rotor net shape fabrication; and 3) coupon and prototype threshold fatigue testing to ensure rotor structural robustness. This innovative team-based concurrent engineering approach enabled us to reduce CAPEX by eliminating complex assemblies and rotor machining while mitigating OPEX by use of non-corrosive e -glass/epoxy composite materials and implementing our state -of-the-art threshold fatigue design protocol to prevent onset of material degradation over the life of the MHK turbine rotor.

Abstract:

Wind energy has emerged as a reliable technology, and as a renewable form, it has benefited from growing policy support which contributed to its sharp rise in share and market. however, the technology still faces some challenges, especially related to its intermittent and part-load operation. Off-design operation is a serious matter because system efficiency drops considerably at off-design loads, one strategy to address this challenge for wind turbine blades and obtain a more consistent efficiency over a wide load range, is varying the blade geometry. Predictable morphing of wind turbine blade in reaction to wind load conditions has been introduced recently. The concept, derived from fish locomotion, also has similarities to spoilers and ailerons, known to reduce flow separation and improve performance using passive changes in blade geometry. In this work, we employ a fully coupled technique on CFD (Computational Fluid Dynamics) and FEM (Finite Element Method) models to introduce continuous morph to desired and predetermined blade design geometry, the NACA 4412 profile, which is commonly used in wind turbine applications. Then we assess the aerodynamic behaviour of a morphing wind turbine airfoil using a two-dimensional computation. The work is focused on resolving force distribution based on trailing edge deflection, wind speed, and material elasticity, i.e., Young’s Module. The computational and wind tunnel results will be presented together with a summary of the prospects for the industry.

Abstract:

NEOM, a £370 billion Megacity in Saudi Arabia is planned to be constructed in the border between this country and Egypt [1], to host a large population. This Mega-city is going to be built to embrace new technologies and lifestyle for the young population of this country. One of the main aims of proposing this green city is to fully supply its energy from the renewable sources such as solar power [2]. Therefore, recently the 200 GW solar power plant has been signed off [3] for supplying the energy requirements for the country. But one of the main users of the electrical energy is the hospitals, for which these solar plants need to have sustainable supply of electricity. The main purpose of this research is to analyse the technical possibilities of using fully green technologies for a conceptual hospital framework. In order to achieve this framework, different disciplines including the power supply, waste disposal [5] and energy wastage are going to be evaluated for the purpose of constructing a conceptual sustainable hospital in the new city of NEOM by considering its geographical location, climate conditions, transport facilities and the demand analyses based on the population demographic data. In this study, a combination of three renewable energy sources; solar, biomass, and wind turbine energy are evaluated by using the HOMER PRO software [6], to fully supply the required power of this modern city.

Abstract:

Energy (or Desert) towers are a renewable energy producing device suitable for hot and dry climates. They are based on spraying sea water from the top of a tower 500 m high. The sprayed droplets evaporate and thus cool the surrounding air creating a downdraft which moves electricity-generating turbines located at the basis of the tower. The air is subsequently delivered through a diffuser to the surrounding environment where the salt containing water precipitate to the ground. The Energy tower generates electricity without producing greenhouse gasses. It has been estimated that approximately 1/3^rd of the gross power delivered by the turbines is necessary for pumping the sea water to the tower site and up the tower, whereas another 2/9^th is lost to aerodynamic friction, leaving 4/9^th as net power. The electricity is generated 24 hours a day (although at a much smaller power during the night) CFD calculations indicate that an energy tower with a 200 m diameter and a 600 m height may deliver a 250 MWe net electrical power and 250 GWh a year. In addition a by-product is desalinated water that can be derived from the cold humid air. The estimated cost of the generated electricity is estimated to 2-3 cents/kWh – which makes it competitive and clean, without green-house gasses. The major environmental effect is the precipitation of salt. Energy towers are suited for latitudes between 20 and 30° which are usually hot and dry.

Abstract:

The dramatic growth of energy world consumption and the evolving sustainability awareness and demand, go ‘hand in hand’ and already have considerable impact on world politics and it’s economics. Wind turbine farms strive ever higher, consume ever larger space, with more complex and costlier logistics for their delivery, erection, maintenance and ‘energy crop’ distribution. This paper reports about research and development results concerning a new design- implementation paradigm of Wind and Renewable Energy Harvesting Complex, situated in the Marine Environment on floating mega-platforms. The essence of the new approach may be summarized as follows: 1. compact (wing to wing) wind turbine arrangement on floating mega-platforms, capable of auto-rotating into the wind, with 30÷60 turbines, each. 2. the platform will support additional wave-turbine rows, solar panels, sea-current activated turbines and marine bio-energy farm. 3. the whole complex facility is produced –constructed-assembled in a coastal industrial fabrication plant and sea-transported-towed and moored in its site of function. 4. the platform, a semi –submersible mega-structure array, will be solved to support all energy storage, guide instrumentation, maintenance and energy crop handling. 5. agglomeration of 4÷6 energy generating platforms, when combined, will constitute massive marine power station. 6. the compact, multi-modal, marine renewable ‘blue energy’ power station is solved for stage-completion, rearrangement and relocation, if and when desired. In conclusion: all logistics of the power station, namely: construction, erection, transportation, mooring-anchorage, maintenance, supervision, energy harvesting and its delivery, are highly industrialized, thus raising dramatically its cost-effectiveness and economic attraction.

Abstract:

This paper covers definition of local, meso and large-scale factors and climate changing role on wind and solar energy potential. Hourly and daily wind speed and solar radiation data define monthly and seasonal variations of wind and solar energy potential. The main aim of the paper is to define wind and solar energy potential variations at two study areas in Istanbul, (Asian Side: Kandilli and European Side: Maslak). Wind speed, solar radiation data cover the interval of 1911-2017. The paper presents some results on descriptive statistics, Wavelet applications, Speedy Model estimates and ANN (Artificial Neural Networks) simulations. Wind data makes use of the Weibull Distribution Function as a tool to represent the frequency distribution of wind speed. Solar energy potential analyses based on Wavelet shows the role of small, meso and large-scale factors on energy potential variations. Extreme winds are associated with large-scale events with periodicities between 5-20 hrs, 5-30 hrs, 30-45 hrs or 20-60 hrs in winter. Small scale and meso scale factors is associated with lower wind speed with periodicities changing up to 35 hrs. A Speedy Model approach was applied when estimating wind – solar energy potential at the site was assessed using a historical data for every 30 year period. As a conclusion available wind speed and solar radiation by using Speedy Model and ANN simulation approach realistic estimate of energy potential. This paper is dedicated to researching the potential wind-solar energy production in Istanbul. They show the role of climate changing on energy policy.

Abstract:

Most countries in the world especially those in Asia and Africa despite undertaking policies meant to help meet Sustainable Development Goal 7, there are still a sizable number of households who have not yet fully embraced energy saving technologies. This study provides highlights on the economic and environmental benefits for investing in energy saving light-bulbs. Using a survey and a multistage random sampling approach, we administered questionnaires to 1,650 households in Ghana. The relevant diagnostic tests associated with cross-sectional data were undertaken. We estimated a maximum-likelihood probit model with its associated marginal effects to find out how choice is influenced by environmental consciousness and other demographic factors. Our results are consistent with economic theory as well as what earlier empirical evidence found in literature. That is, environmental consciousness (both local knowledge and global knowledge), education, income etc. are very important in explaining the choice of buying energy saving light-bulbs in Ghana. Besides advocating for information that will make society more environmentally conscious, we further recommend the use of fiscal policies (i.e. subsidies) to support lower income brackets who are predominant in developing countries.

Abstract:

This paper aims to identify the factors affecting the use of Performance Measurement Systems in wind farms O&M to increase reliability and productivity. A case study was conducted with 7 Brazilian companies which together own 41 wind farms in the state of Rio Grande do Norte, which has the largest installed capacity in the country (32%). As a result of this research, have been identified: (1) The need of making efforts to define what indicators are important to measure. The performance indicators available in the literature are very specific, so it is necessary to analyse the main constraints that affect subsystems and equipment to define what should be measured. (2) Performance measurement based only on indicators defined in contracts. Due the terms of the Operation and Maintenance contracts the managers prioritize a specific indicator (Time Based Availability), at the expense of those who actually illustrate the farm's productivity.  (3) Difficulties in monitoring the activities of contracted companies, and also obtaining and validating the results presented by them. The data provided by the contracted companies are not always sufficient and reliable, since they are linked to the possibility of incidence of contractual penalty. (4) Use of non-specific software. Software adapted from other types of industry and not suitable to the reality of wind farms encode the measurement process, rather than facilitating it, and this discourages its use by those involved.  (5) Non-use of the indicators results for the decision-making processes and uncertainties about the strategies of action to be adopted when the indicators reach critical limits, generating a lack of commitment to future measurements.  (6) Non-use of tools for wind turbine performance analysis. Generation losses in wind farms are generally associated with unavailability of wind turbines. However even in operation, wind turbines may be producing less energy than they should due to problems that cause power limitation. Although few companies use specific tools to make this kind of analysis feasible. In addition, performance analyses require access to raw turbine data, which are often not available from manufacturers.  (7) Need to extract data from different systems and transform it into indicators. Most wind farms hire one company to operate the turbines and another to operate the electrical system. These companies use different systems that do not allow the direct exchange of data between them, leaving the responsibility for the managers to extract data from the systems and turn them into useful indicators. This makes it difficult to analyse data, especially in wind farms with a great number of wind turbines. The factors that affect the use of performance measurement systems in the operation and maintenance of wind farms are mostly managerial factors. Therefore, the development of a management culture focused on performance improvement and the training of managers in this theme can enable the successful implementation of this type of tool. The implementation of performance measurement in wind farms can enable the achievement of improvements in processes and increase operational efficiency, resulting in generation gains. With this, it is possible to increase the competitiveness of the wind power source compared to other non-renewable energy sources, contributing to the diversification of the national electricity grid.

He is an associate Professor at Aarhus University and is working with fracture of materials especially ultra high performance concretes. He has published more than 40 papers.

Abstract:

Recently there has been an increasing interest in concrete towers for wind turbines primarily due to the fact that there is a larger demand for bigger wind turbines and higher towers, resulting in larger base diameters for these towers. Production of such towers in steel is complicated and expensive and so is transportation and erection of the towers on site. Instead smaller segments of Ultra High Performance Fibre Reinforced Concrete (UHPFRC) can be transported to the site by trucks and assembled on site. UHPFRC is characterized by high and compressive strength combined with an extreme high fracture energy makes it possible to make wind turbine towers of heights of over 200 m. The two main concerns are the eigenfrequencies of the tower and the fatigue resistance. This study is on the dynamic behavior of an 31.2 m high experimental UHPFRC post-tensioned wind turbine tower. The dynamic stiffness of the whole system and the soil-foundation-structure interaction is determined using Operational Modal Analysis (OMA). In addition a series of low-cycle fatigue experiments have been performed. Experiments on beams in three point bending have been performed in a newly developed test set-up. Both static and fatigue loading were carried out. Due to the high fatigue resistance of the material, focus has been on low cycle fatigue. In the tests, it is seen that the descending branch of the static experiments can be correlated to the fatigue life, indicating static tests can be used for quality control of the fatigue life.

Abstract:

In recent years, the increasing penetration of Renewable Energy Systems (RESs) has made an impact on the operation of the electric power systems. In the grid integration of RESs, data acquisition systems and communications infrastructure are crucial technologies to maintain system economic efficiency and reliability. Since most of these generators are relatively small, dedicated communications investments for every generator are capital cost prohibitive. Combining real-time attack-resilient communications middleware with Internet of Things (IoTs) technologies allows for the use of existing infrastructure. In this talk, I will present our work in developing an intelligent communication middleware that utilizes the Quality of Experience (QoE) metrics to complement the conventional Quality of Service (QoS) evaluation. Furthermore, our middleware employs deep learning techniques to detect and defend against congestion attacks.

Abstract:

Absorption coefficient of emission gases of carbon dioxide responsible for temperature in the troposphere layer, which is less than the altitude of 10 km in the atmosphere, is presented in this work. It has been well known that the solar irradiation within short wavelength range near the visible range can be absorbed, scattered and transmitted by the atmosphere and absorbed and reflected by the earth ground. The ground emits radiation in the ranges of long wavelengths. In the presence of carbon dioxide and other emission gases, the atmosphere acting as the glass of a greenhouse increases temperature of the atmosphere. Even though global warming strongly affects the life of the human being, the cause of global warming is still controversial. This work thus establishes a fundamental, systematical and quantitative analysis of absorption coefficient of carbon dioxide in the troposphere layer. Absorptions of carbon dioxide are considered in bands centered at 15, 10.4, 9.4, 4.3, 2.7 and 2 micro meters. The predicted absorptions agree with experimental and theoretical results in exponential wide band model.
