Doubly fed induction generators (DFIG's) became the predominant generator installed for wind generation applications today.

Sources pertaining to the operation and control of DFIG's subsequently became apparent, particularly in weak areas of the grid network.

One of the problems that emerged was the quality of the voltage in the network at the point of common coupling (PCC) with the DFIG.

This Investigation study were undertaken for a 2MW DFIG connected to the grid have a background voltage distortion of 5th, 7th, 11th and 13th order harmonics.

This paper proposes a control schemes to alleviate the problem caused by the voltage distortion in the grid, which is introduce the stator current harmonics in the DFIG wind turbine, the control techniques to improve the performance of DFIG during voltage distortion in the grid including measures to controlling the grid side converter and the rotor side converter in a DFIG.

The proposed current controller is developed based on proportional integral and multi resonant (PI+MR) controller to suppress the stator current, a six and twelve order resonant controller.

As a result, the THD for the stator current are minimized from 5.63% using proportional (P), 4.22% proportional Integral (PI) and 1.95% proportional Integral and Derivative (PID) to 0.37% using (PI+MR) for full load.

Finally the behavior of DFIG's to the effect of distortion grid voltage under the effect of wind speed, voltage and frequency variation is further investigated and the results validated by MATLAB simulation.
