摘　　要：在微电网中,光伏发电与风力发电均具有随机性,为保证供电的可靠性,需要在系统中配置一定的储能单元来维持实时功率的平衡,保证微电网供电的可靠性。该文结合工程实际,采用锂电池和超级电容器混合储能系统,建立基于储能系统全寿命周期的目标函数,构建能量约束、功率约束和负荷约束,并用粒子群算法进行求解,验证混合储能系统的优越性。In the micro-grid system,photovoltaic and wind power generation has a certain degree of randomness,in order to improve the reliability of electricity supply of micro-grid,it is necessary to configure a certain energy storage unit in the system to maintain the balance of real-time power and ensure the reliability of micro-grid power supply.In this paper,first of all a hybrid energy storage system by lithium battery and supercapacitor is proposed.And then an objective function based on the whole life cycle of the energy storage system is established,an energy constraint,a power constraint and a load constraint are constructed as well.Finally,the superiority of the hybrid energy storage system is verified by the particle swarm algorithm.
