Performance of wind energy conversion system using a Permanent Magnet Synchronous Generator for maximum power point tracking

Abstract

This paper present a control method which tracks the maximum power point for a wind energy conversion system based on Permanent Magnet Synchronous Generator (PMSG) fed by back to back voltage source converter. The control strategy for the generator with maximum power extraction is presented. The MPPT control algorithm is presented based on perturb and observe method. The algorithm operates at two modes. Mode-1 obtains the maximum power point (Pref). In the next mode Pref is kept unchanged till this mode calculates the new value of optimum power at new wind speed. Simulation results shows that the controllers can extract the maximum power.
