Abstract: In wind power generation system, the output power will occur pulse wave which will influence the stabilization of the whole system, due to the variation of the wind direction and wind power. The energy storages system can smooth the fluctuation of output power and improve the stabilization of the generate electricity system. This paper analyzed the development of the compose energy storage system in the wind power generation system, and then proposed a kind of the composite energy storage system, established the model of this composite energy storage system in the PSIM. Through simulation experiment, it is showed that the system can easily smooth the fluctuation, when the frequency of the input power is 0.2～0.9 Hz, and the reality control and drive circuit of the composite storage system was tested.

Key words: smooth power fluctuation, composite storage system, electricity quality, bi-directional
