Abstract
Recently, there is a prompt growth in wind energy exploitation due to its remarkable merits. In the other hand, intermittent and uncertain nature of the wind energy remains as a main obstacle in efficient utilization of this type of energy which could affect lots of problems related to power systems involved wind power. Determining the optimum penetration capacity of wind farms is an important problem in power system expansion planning or in a power system which the total capacity of its conventional units are given. To solve this problem, two schemes could be used as a constraint to limit the wind farm’s capacity which are: 1) the maximum capacity of the wind farm is equal to a certain percentage of total existent conventional units, 2) the maximum utilizable power of the wind farms is equal to a certain percentage of the peak load. This paper by using a Cost/Risk analysis shows that the second scheme is more preferred. Monte Carlo Simulation method has been used to show the uncertainty of wind speed which is modeled by using Weibull distribution. Applying two mentioned schemes, the optimum penetration capacity of wind farm to a power system with definite conventional power units is planned. To do the risk analysis, different mean values are considered for wind speed and the total operational cost and penalty value of the power system is calculated. Numerical analyses conducted on the IEEE 24-bus RTS system. The obtained results are discussed in depth.
