To increase the penetration of wind turbines, participation of latter in power system management is required, this work evaluate the participation of a wind farm in primary frequency regulation. To participate in primary frequency control, wind farms must have some power reserves; over-speeding technique is used to satisfy power reserve required by the network operator. Control strategy for a wind farms to participate in power system frequency regulation, based on a combination of inertial response and de-loading control is proposed. The wind farm detects the frequency changes and starts to participate in frequency regulation. The combined control scheme using both controllers is also developed. Simulation results are presented to demonstrate the frequency regulation capability and validate the effectiveness of the proposed strategy.
