摘　　要：蓄电池容量优化是提高风光储能系统性能及经济性的重要途径。总结了储能系统中蓄电池模型的建立,特别是荷电状态SOC的分析,重点结合电池模型讨论了精确确定储能系统中蓄电池容量的方法。为了考虑蓄电池性能的衰减对储能系统的影响,指出利用安培电流法分析荷电状态并提出将电池容量的衰减耦合到荷电状态的分析思路。此外还基于负荷缺电率LPSP和平准化成本LCE的概念,从可靠性及经济性方面对储能系统进行了优化分析。To improve the performance as well as reduce the overall cost of PV/wind energy storage system,it is quite necessary to optimize the battery capacity.The different types of battery model especially the concept of state of charge(SOC)in detail were discussed.The battery capacity was determined based on those models,and ampere hour counting method(AH method)was preferred.The idea that the battery capacity loss should be considered was proposed while analyzing the battery SOC.Finally,the battery capacity was optimized by the reliability model and the economic model which were mainly based on the LPSP and LCE concepts respectively.
