In this paper a novel method for controlling DFIG based wind turbine is proposed in order to compensate the most prominent harmonics of the utility grid in addition withproviding required network active and reactive power. This harmonics elimination provide better power quality and power capturing of wind energy fluctuating wind speed concurrently.Direct power control (DPC) is applied to control DFIG by employing voltage space vectors of rotor side converter (RSC)using optimum switching table based on stator flux position and active and reactive power states. Distorted active and reactivepower of the nonlinear load is measured. Then they are added to active and reactive power reference of DFIG respectively for harmonics compensation. Simulation results on a 2 MW DFIG demonstrate robust, precise, and fast dynamic behaviour of the machine.
