Using energy storage system is an effective measure to compensate wind power fluctuation. First, this paper proposes to use hybrid storage energy system to compensate main components according to frequency content analysis of wind power fluctuation. This system consists of storage battery and super-capacitor. And then, it sets up fuzzy sliding control strategy of hybrid energy storage system. The fuzzy controller can eliminate chattering of sliding controller. According to step response of control system under disturbance, it verifies the high immunity performance of fuzzy sliding controller by the wind power hybrid energy storage system simulation model on RTLAB. At last, the simulation calculation shows the output and state of charge (SOC) of energy storage system, which verifies the effectiveness of the hybrid energy storage system controller on compensating the fluctuation and improving disturbance rejection.
