Résumé: Due to their advantages especially the capability of operation at wide wind speed ranges, doubly-fed induction generators (DFIGs) are widely used in wind energy conversion systems (WECSs). This paper introduces a performance enhancement of WECS-DFIG by extracting the maximum power from WECS-DFIG in addition to active and reactive powers control. The maximum power point is extracted by capturing the optimal speed by an intelligent controller. While Integral Sliding Mode Controller (ISMC) and the Field Oriented Control (FOC_PI) are presented for active and reactive powers control. The proposed controllers were applied to control a 1.5 grid-connected DFIG. All simulations were done using Matlab Software.
