Doubly-fed induction generator (DFIG) wind turbin e has been extensively used in wind energy conversion system due to its fine energy capture performance, good controllability and simple implementation. In this paper, we examine a non linear control based on the high order sliding mode (HOSMC) for the direct torque control (DTC) of a DFIG incorporated in a wind energy conversion system and associated with a storage unit. This research is carried out to reach two main objectives. Firstly, the DFIG rotor side converter is controlled by HOSMC-DTC in order to achieve good performances. The second objective is the association a storage unit, in parallel with the DC bus, to obtain a smooth as much as possible the power supplied to the network grid. Finally, the simulation results showed that DFIG wind turbine with storage unit could provide a much smoother power output at different wind conditions comparing with the conventional DFIG wind turbine.
