A Fuzzy Logic Based Power Electronic System for Wind Energy Conversion Scheme

This paper used fuzzy logic theory to study the behavior of a simple pulse width modulated three phase voltage controlled VSI, which feeds a weak AC network with power produced from an offshore wind farm (WF) of induction generators. Its control system, which is based on fuzzy controllers, manages to offer very satisfactory performance. Using Matlab simulation, the study was performed under both steady-state and transient conditions. The results have proven an excellent performance and verified the validity of the proposed system. The studies have also demonstrated the ability of the advanced inverter to assist the system keeping the ac voltage fluctuations in the point of common coupling at an acceptable level.
