This papers deals with the control of active and reactive powers in wind energy conversion systems (WECS) powered by dual-stator-winding squirrel-cage induction generators (BDFIG). In these systems, the MPPT technics based on a torque control present coupling with reactive power objectives. A High Order Sliding Mode MIMO control is proposed for satisfying the power objectives in a decoupled way. The robustness of the Super Twisting MIMO controller is evaluated for different power requirements and wind profiles. A Pitch Angle Control allows extended the work range of WECS. The results are analyzed via simulations.Instituto de Investigaciones en Electrónica, Control y Procesamiento de Señales
