In allusion to the active power fluctuation of wind power, a filtering mean combianing adaptive moving average with variational mode decomposition is proposed. Firstly, according to typical wind farms process data ,the adaptive moving average method is used to determine the grid-connected power of wind power and the charge-discharge power of hybrid energy storage system. According to the characteristics of energy storage and power storage, The hybrid energy storage power is decomposed into a series of sub-modes from low frequency to high frequency by variational mode decomposition method to complete primary power distribution. Secondly, for the low density of power-type energy storage, the phenomenon of over-charge or over-discharge is likely to occur, The charged state of the power storage element monitored in real time. The primary power of hybrid energy storage is modified by fuzzy control.The results show that not only the the active power fluctuation of wind power can be well controlled, but also the hybrid energy storage system can work reasonably and safely.
