Low voltage ride through analysis of FSIG based WECS with STATCOM

Among the renewable energy technologies being vigorously developed, Wind turbine technology has been undergoing a dramatic development and now is the world´s fastest growing energy. The continuous increase in wind power penetration level is likely to influence the operation of existing utility networks, especially the power system stability. Because of clean and economical characteristics, Wind energy is considered as one of the prospective energy sources of the future world. The present target is to achieve 12% generation of the world´s electricity fro, wind power by 2020. The new European Wind Energy Association scenario shows that by 2030, wind power could be satisfying 22% of Europe´s total electricity supply. From these predictions, it can be easily comprehended that a huge number of wind farms will be connected to the power system in the near future. Therefore it is essential to analyse the characteristics of wind generators during the network disturbances.
