Modified Particle Swam Optimization based LVRT control strategy for grid connected WECS

Abstract

Modified Particle Swam optimization (MPSO) based LVRT control strategy for grid connected WECS is proposed to improve the performance of converters coordination using intelligent controllers. Through this we can expect any facts controllers and external controller circuits like current limiters the coordination of the back-back converters coordination is improved. The intelligent controllers like Fuzzy logic permits creating definite selections supported inaccurate or ambiguous information and artificial neural network (ANN) tries to include the human thinking method to resolve issues while not mathematically model. Hybrid system with the combination of ANFIS and PSO is proposed in this paper optimize the objective function. The proposed hybrid control scheme will improve the performance of the WECS under LVRT conditions and it has been verified through MATLAB.
