The control strategy of wind power generator energy storage converter under voltage fluctuations is studied to enhance the capability when the access point voltage fluctuate. Energy storage converter decoupling control of active and reactive power could be achieved through the three-phase instantaneous reactive power theory. Simulation results showed that under voltage fluctuation the energy storage converter could support reactive power and accelerate the power grid recovery to normal rapidly.
