This paper deals with the Active and Reactive Power control of double-fed induction generator (DFIG) for variable speed wind turbine. For controlling separately the active and the reactive power generated by a DFIG, field oriented control (FOC) and indirect sliding mode control (ISMC) are presented. These non linear controls are compared on the basis of topology, cost, efficiency. The main contribution of this work based to the short time of response with excellent convergence and high decoupled between active and reactive power in one part and in the second part we define the benefit to use indirect model of DFIG to the conception of indirect sliding mode control by using the relationships between stator powers and rotor currents. The simulation results have shown good performances concerning the tracking of the references both in transient and steady state and prove the effectiveness of sliding mode control to track the given references using PWM inverter.
