Abstract
Simulation of wind energy conversion systems of doubly fed induction generator to improve the efficiency of the steady state error is identified in this paper. On focusing the steady state condition the active power output of the wind energy conversion system is observed. To reduce the error a proportional integral controller is attached to the system output. The PI constants are taken through trial and error method to limit the steady state error of the active power output. Adding up to it, The behavior of DFIG ( i.e; torque, rotor speed, and the other characteristics )are observed under the grid voltage . Simulation of model is carried out in MATLAB Software. Necessary outputs are noted.
