N2 - The increasing penetration of wind farms based on DFIGs in power grid will result in reducing the capability of primary frequency control. To implement the frequency supporting of DFIGs, a frequency control strategy is proposed based on the combination of active power backup and droop control. The effects of DFIG operating characteristics and aerodynamic characteristics on the participating frequency regulation under different wind conditions are studied. Resetting reference set-point by rotational speed and blade pitch angle control, DFIGs obtain the active power backup when operating normally. When a power imbalance occurs and the system frequency deviates, DFIGs can respond to the frequency deviation by the frequency-power droop control, thereby implementing the system frequency regulation of DFIGs participating in. The simulation to testify the validity of the proposed strategy is established in PSCAD/EMTDS. The simulation results show that applying the frequency control strategy can improve obviously the dynamic performance of frequency events.
