摘 要:大規(guī)模風電并網會嚴重影響電力系統(tǒng)的穩(wěn)定運行及安全。分析了不同種類儲能系統(tǒng)特性的情況,提出在系統(tǒng)內配置由超級電容器、電池儲能以及抽水蓄能構成的復合儲能系統(tǒng),充分利用電池和超級電容器充放電較迅速的特點以平抑風電功率波動,利用抽水蓄能機組調節(jié)容量大的特點進行削峰填谷,以獲得最小系統(tǒng)總成本為目標,對該復合儲能系統(tǒng)的配置容量進行優(yōu)化。以改進的IEEE RTS-96系統(tǒng)為例,并基于國內某風電場的歷史出力數據,進行了仿真計算分析。仿真結果驗證了該復合儲能模型及其容量優(yōu)化方法的有效性,在一定程度上提高了風電的滲透率以及系統(tǒng)的運行經濟性。

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
