An Effective MPPT Controller for Power Optimization of PMSG Based Wind Turbine

Keeping in view the sporadic nature of wind, the output power of wind turbine continuously oscillates leading to inefficient power generation. Therefore, a maximum power point tracking (MPPT) mechanism must be included within the system in order to ensure its optimal operation under every possible condition. Over the years, a number of MPPT techniques have been devised each aiming to optimize the output power response from a wind energy conversion system (WECS). This paper presents a comprehensive comparison between two most commonly used MPPT schemes for power optimization i.e. Perturb & Observe (P & O) and Fuzzy Logic Control (FLC) for a Permanent Magnet Synchronous Generator (PMSG) based WECS. The research work compares their performances in terms of the response time, tracking efficiency, output power & performance coefficient (Cp). The simulation results clearly show the superiority of fuzzy logic control over perturb and observe method. The results are validated through simulation in MATLAB/Simulink environment.
