摘　　要：为提高光伏充电站的光伏利用率,需要合理配置光伏组件和储能系统的容量。考虑到大量退役动力电池亟待回收利用的现状,结合梯次利用电池储能系统,建立了基于退役动力电池梯次利用的光伏充电站的光储容量配置模型,以充电站年净收益最大为目标函数,采用粒子群算法对模型优化求解,确定出光伏充电站最优的光储配置容量。结合算例对光伏充电站配置常规电池储能和梯次电池储能两种情况进行经济性对比。结果表明,在相同配置情况下采用梯次电池储能系统的经济性更好。To improve PV utilization of PV-based electric vehicle station,it is necessary to configure the capacity of PV modules and energy storage devices reasonably. Considering the current situation that a large number of out of use power batteries need to be recycled urgently in China and combining with second-use battery energy storage system（ BESS）,the optimization model for capacity configuration of PV-based electric vehicle station based on second-use batteries was built. The maximization of annual net income is used as the objective function of the model and the PSO is used to optimize the model. The economical efficiencies of PV-based electric vehicle station with conventional BESS and with second-use BESS were compared and analyzed. The computation results show that under the same configuration a higher economical efficiency can be achieved by the use of second-use BESS.
