The paper present the modeling and control of 1.5 MW wind energy conversion system (WECS) equipped with a DFIG for a variable speed. A bidirectional converter is employed for the power conversion exchanged between the machine stator and grid. The control strategy of DFIG and rotor side converter (RSC) combines the technique of MPPT included the control of the generator speed by Proportional Integral (PI) and vector control (VC). In the control system of the grid side converter (GSC) the application of direct power control (DPC) has been used. The results of simulation of the global control system have been presented and discussed.
