主　　题：Current feed forward control DC-link voltage frequency droop control frequency support PMSG-based WTs 

摘      要：Frequency droop control is widely used in permanent magnet synchronous generators(PMSGs)based wind turbines(WTs)for grid frequency ***,under frequency deviations,significant DC-link voltage fluctuations may occur during the transient process due to sudden changes in real power of such *** address this issue,a current feedforward control strategy is proposed for PMSG-based WTs to reduce DC-link voltage fluctuations when the WTs are providing frequency support under grid frequency ***,the desired frequency support capability of the PMSG-based WTs can be *** results verify the rationality of the analysis and the effectiveness of the proposed control method.
