Critical study for control of wind energy conversion system

This paper presents a critical study for control of Wind Turbine based Permanent Synchronous Generator WT-PMSG). The aim of this study is to compare the performances of distinct strategies strategies; Second Order Sliding Mode (SOSM) controller, Fuzzy PID controller (FPID) and the conventional PI controller. The selected strategies are tested under low-high wind speed regions for tracking the Maximum Power Point (MPPT) and in other hand protection of WT. Moreover, the controllers parameters are successfully tuned by a capable metaheuristic optimization called Bat algorithm (BA). Simulation results proved that the optimal SOSM controller performs better than the other optimal I controllers in terms of response, overshoot and indices performances.
