چکیده
In this paper direct power control (DPC) strategy is applied to control a doubly fed induction generator (DFIG) based wind energy generation system. A AC/DC/AC converter is controlled by direct power control method. The rotor side converter is controlled by selects appropriates voltage vector based on the instantaneous errors between the reference and estimated values of active and reactive powers and rotor flux position. Also the Grid side is controlled by direct power control based a grid voltage position to ensures a constant DC voltage, Simulation results demonstrate robust, precise, and fast dynamic behavior of system.
