Selection of wind farm location based on fuzzy set theory

This paper presents an approach to select the proper location of wind farm in power system. Two key factors for constructing wind farm are considered in this study. They are wind availability and wind speed. Because of the “undispatchable” nature of wind and the difficulty in forecasting, the wind availability and wind speed are random and uncertainty. Thus, the deterministic method is not appropriate to handle them. This paper uses fuzzy number to deal with the wind availability and wind speed. The term of average unavailable time (AUAT) is introduced in order to compute the probability of average wind availability. The proposed approach for selecting wind farm has been applied to the IEEE 30-bus test system.
