Application of Direct Power Control in Wind EnergyConversion System

K. Bedoud, A. Rhif, T. BAHI, H. MERABET

Abstract: This paper describes the performance evaluation of thedirect power control for a three-phase pulse with modulationinverter fed by a variable speed wind energy conversion system.This, to ensure a maximum power point tracking of a wind.Proposed direct power control strategy is implemented in the d-qreference frame. The system modeling and control scheme areimplemented on Matlab/Simulink. The simulation results show thatthe use of the direct Power Control provide nearly sinusoidal inputwave form current, constant switching frequency operation,regulation of unity power factor in the connection of the grid sideconverter with the grid and the maintain of the DC-link voltageconstant. Finely, the results verify the validity and effectiveness ofthe proposed control.
