This paper presents the modelling and control designs of Double-Fed Induction Generator (DFIG) integrated into a wind energy conversion system (WECS). The aim is to design and compare two distinct strategies of controlling independently the active and the reactive power generated by a DFIG, in order to conclude on their performances. In first place, a modelling of wind turbine and DFIG is presented. Then, the PI controller, the Backstepping approach and a maximum power point tracking (MPPT) strategy used to extract the maximum of power during the conversion are developed. Simulations results show significantly improved performances of the proposed backstepping approach over the Proportional-Integral controller, in terms of dynamic response, disturbance rejection, and robustness against parametric variations. The systems performances were tested and compared using Matlab/Simulink Software.
