Fuzzy risk index of wind sites

The authors present a method for the computation of the fuzzy risk index of wind power plant sites, where the installation of wind energy conversion systems seems to be possible in the near future. The approach is based on fuzzy sets theory. The fuzzy variables are both the wind speed and its frequency of occurrence, as they are measured on the site. The method was applied to the wind data of the Greek islands, focusing on extreme wind events. The results of the application are compared to those obtained through a classical risk analysis to illustrate the effectiveness of the proposed fuzzy risk index approach.<
