摘　　要：采用混合储能系统能够降低储能配置的年均综合成本,提高光伏发电系统的经济效益。针对超级电容器-飞轮-蓄电池混合储能系统,采用经验模态分解方法把光伏发电功率与负荷功率之间的不平衡功率分为高频、中频和低频三部分,分别作为超级电容器、飞轮和蓄电池的参考功率;构建以年均综合成本最小为目标函数,同时考虑混合储能系统的充电与放电功率和剩余电量等约束条件的容量优化配置模型,采用遗传算法进行优化,并通过实例分析验证了该配置方法的有效性。Through the utilization of the hybrid energy storage system, the annual comprehensive cost of energy storage system canbe reduced and the economic benefit of photovoltaic power generation system can also be improved. The empirical modedecomposition method is used to decompose the power imbalance between photovoltaic generation and load into high frequencycomponent, intermediate frequency component and low frequency component, which is taken as the reference power of supercapacitor, flywheel and battery respectively. In addition, this paper established capacity allocation optimization model with theannual cost as objective function, charging/discharging power and state of charge as the constraints. Genetic algorithm was thendeployed to minimize the objective function. Finally the case study result verified the effectiveness of the configuration strategy.
