Comparative study of four MPPT for a wind power system

Abstract

The Maximum power point tracking (MPPT) command makes it possible to find the optimal operating point of the wind generator following variations in the wind. Its principle is based on the automatic variation of the power coefficient to continuously maximize the power of the wind generator. This work is an attempt to study and discuss four most popular types of MPPT techniques such as: Perturbation and Observation (P&O), optimal torque (OT), On-Off control, and tip speed ratio (TSR). The Matlab-Simulink environment is used to analyse and then interpret the simulation results of these algorithms, and therefore show the performance and limitations of each algorithm. The comparison shows the efficiency and the superiority of the OT technique compared to the other MPPTs studied.
