Maximum power point tracking control of wind energy conversion system driving a permanent magnet synchronous generator: Comparative study

Abstract

A wind energy conversion system needs a maximum power point tracking strategy. In the literature, several works have interested in the search for a maximum power point. Generally, their goals are to optimize the rotation speed or the machine torque and the direct current–direct current or the alternating current–direct current duty cycle switchers. This work presents a comparative study between two maximum power point tracking strategies of a wind energy conversion system. The model of the system is studied and developed. It includes a permanent magnet synchronous generator, a diode rectifier and a three-cell direct current–direct current converter. The direct current–direct current is controlled in order to generate the wind maximum power using the tip speed ratio strategy and optimal torque strategy. The effectiveness of the used strategies control scheme is proved by simulation results using MATLAB/Simulink.
