摘要：
A control strategy is proposed for the DFIG (Doubly Fed Induction Generator)-based wind farm in microgrid, which, in grid-connection mode, tracks the maximum wind power and adjusts the output reactive power by sensitivity analysis to depress the voltage fluctuation caused by active power variation, while in islanding mode, controls the amplitude and frequency of DFIG voltage and imitates the droop characteristics to cooperate with other distributed generators with droop control. Simulative results show that, the proposed strategy adjusts the active power balance of microgrid and maintains the voltage stability of system, supporting the stable operation of microgrid in either grid-connection mode or islanding mode.
