OPTIMAL TUNING OF RST CONTROLLER USING PSO OPTIMIZATION FOR SYNCHRONOUS GENERATOR BASED WIND TURBINE

Abstract

In this paper, we present an optimized RST controller using Particle Swarm Optimization (PSO) meta- heuristic technique of the active and reactive power regulation of a grid connected wind turbine based on a wound field synchronous generator. To continuously extract the optimal aerodynamic energy, a maximum power point tracking (MPPT) algorithm based on fuzzy logic theory is designed. The performance of the Wind Energy Conversion System (WECS) with the proposed controller is tested for fast wind speed variation using Matlab/Simulink. Simulation results demonstrated the potential of achieving maximum power tracking for the wind speed profiles considered and a considerable reduction in the torque ripples with the PSO optimized RST controller as compared to a classical controller. The results also showed a good transient response and robustness of the proposed control system.
