    Abstract: Large-scale wind power integration brings adverse effects to system’s steady operation and security. This paper analyzed the conditions of different kinds of energy storage systems characteristics, proposed to configure a hybrid energy storage system (HESS) composed of super capacitor (SC), battery energy storage system (BESS) and pumped storage power station, took full advantage of the rapid charge-discharge characteristics of batteries and super capacitor to stabilize the wind power fluctuation and made use of large pump storage group adjusting capacitor characteristics to carry out peak clipping and filling valley, so as to get the target of minimum system total cost, which optimized the configuration capacity of HESS. Taking the improved IEEE RTS-96 system for example and based on the historical contributing data of certain domestic wind power plant, computational analysis was carried out simulation. The results prove the effectiveness of the proposed method and it can improve the penetration of wind power and the power system operating economy.
    Key words: battery energy storage; hybrid energy storage system; pumped storage power station; super capacitor; wind generation
