Abstract：The power system equivalent inertia and the frequency stability decline with the increasing penetration level of wind generation. To remedy this situation, many countries have put forward grid codes which require large-scale wind farms to participate in the system frequency regulation and provide inertial responses as synchronous generators do. Through time-domain simulations and additional eigenvalue analysis, the impacts of wind farm inertia control on the wind generation system and on the power system operating characteristics have been studied. The traditional wind farm inertia control is beneficial to the system frequency stability. However, the simulation results indicate that the inertia control reduces damping of the drive-train torsional mode, which may lead to speed oscillation instability. To solve this problem, the inertia control involving active damping for the drive-train torsional oscillation is proposed. The proposed control facilitates the wind farm to fulfill the grid code requirement regarding the inertia control and suppresses the drive-train torsional oscillation. The simulation results validate the effectiveness of the proposed control.
