In this paper, a new nonlinear control method based on differential flatness is applied to a high-power wind energy conversion system connected to the grid. The control system is done by planning the appropriate trajectories on components of the output variable vector of the system. The main advantage of the proposed method is control of the system even during the transient state as well as the high performance. The studied system includes a three-bladed horizontal wind turbine and a permanent magnet synchronous generator (PMSG) which is connected to the grid through a back to back converter and a filter. In order to study performance of the control strategy, a random profile of the wind speed has been used. The simulation results obtained in Matlab/Simulink environment are presented to validate efficiency of the control strategy.
