Improvement of doubly fed induction generator wind energy conversion system using robust backstepping non linear control

In this paper, we present a robust control of the doubly fed induction generator (DFIG) using in the wind energy conversion system (WECS). We started by using the maximum power point tracker (MPPT) method to extract the maximum power in the WECS, then modeling DFIG and applied the Backstepping method in order to control the reactive power, and electromagnetic torque. The details of the control strategy and the simulation of all the system components were performed using MATLAB/Simulink software. The results presented in this paper are used to evaluate the efficiency of the proposed control strategy.
