摘　　要：对于包含储能系统的配电网运行建模与仿真,传统方法由于缺少对储能系统变量增补约束,导致建模后储能系统的电热转换效率较低。为此,提出高比能二次锂电池电极材料的储能系统配电网运行建模与仿真研究。依据储能系统在配电网中的运行特性,建立储能系统等效电路,并以高比能二次锂电池电极材料的储能系统的经济性指标构建电网运行模型,同时对其加以变量增补约束,以动态描述配电网的运行过程。实例应用结果显示,所提方法能够有效提高储能系统的电热转换效率,建模结果更加可靠。For the operation modeling and simulation of distribution networks containing energy storage systems,traditional methods lack additional constraints on energy storage system variables,resulting in a high network loss rate of the modeled system.Therefore,a method for establishing a power grid operation model and conducting distributed simulation research,an energy reserve system that includes batteries with charging and discharging performance,is proposed in the thermal storage contact technology.Based on the operational characteristics of the energy storage system in the distribution network,an equivalent circuit for energy storage is established,and a power grid operation model is constructed with the minimum network loss of the energy storage system.At the same time,variable supplementary constraints are added to it to dynamically describe the operation process of the distribution network.The results show that the designed algorithm can improve the stability of energy storage systems,reduce operating costs,and achieve better and better shading effects.
