Abstract: During disturbances, the wind energy generation apparatus are connected for stability improvement, to the grid. Distributed generation Grid failure, a major challenge particularly for PM synchronous wind turbines connected, back-to-back to converters and generator. The need of generated wind power grid integration protocol in terms of active and, reactive power control and failure travel (FRT) capacity needs to be discussed. Here a solution is presented which while fulfilling requirements of LVRT on grid failures, over voltage at dc – link suppression through improved BTB controllers, having a limit on active power, keeps the grid inverter peak current under safe limits during various asymmetric grid defect. By using the proportional and integral control loops, the inertia moment in the wind turbines will be reduced and dynamic performance can be improved. However, during the problem, the calculation time is more. Computational time is reduced by considering a proportional resonant controller and is implemented in the system, where by the active grid oscillation and dc – link voltage ripples are reduced. The validity and effectiveness of the proposed control approach were demonstrated in various conditions through simulation
