摘要：

Large scale integration of DFIGs-based wind farms in power system would reduce system equivalent inertia and capability of primary frequency control. To enhance DFIG frequency control ability and avoid secondary frequency drop, this paper presents a new frequency control strategy based on combination of virtual inertia and over-speed control. DFIGs work at higher speed using over-speed control to store more kinetic energy and gain reserve capacity, and their active power output can be changed with virtual inertia control to respond frequency deviation after system disturbance. Using this proposed method, DFIGs achieve frequency regulation performance similar to that of synchronous generators, providing effective inertia support and certain reserved capacity and reducing risk of secondary frequency drop. Simulations performed verified validity of the proposed method. ©, 2015, Power System Technology Press. All right reserved.
