The invention discloses a power supply and charging station configuration method based on a charging load space schedulable characteristic. The method comprises the steps of firstly, collecting data of all parts in the system , and carrying out load modeling on a photovoltaic power station, a micro gas turbine and an electric vehicle in the system; secondly, determining the optimal installation position and installation capacity of the distributed power supply and the electric vehicle charging station in the power distribution system by taking the minimum annual social total cost as a target;and then representing the relationship among the state quantities in the system by using a linearized Distflow power flow equation, processing branch current constraints by applying a second-order cone relaxation technology, and finally presenting a mixed integer second-order cone programming model which can be solved in polynomial time. The method provided by the invention has the beneficial effects that the method obtains the operation parameters of the power distribution network, solves the target function, effectively improves the spatial distribution condition of the load of the power distribution system, and provides help for the safe and economic operation of the power distribution system.

    本发明公开了基于充电负荷空间可调度特性的电源与充电站配置方法。步骤包括:首先收集该系统中各部分数据,对系统中光伏电站、微型燃气轮机、电动汽车负荷建模,其次以年化社会总成本最小为目标确定配电系统中分布式电源与电动汽车充电站的最佳安装位置和安装容量,之后以线性化的Distflow潮流方程表征系统中各个状态量间的关系,并应用二阶锥松弛技术处理支路电流约束,最终呈现为一个在多项式时间内可解的混合整数二阶锥规划模型。本发明的有益效果为:获得配电网运行参数,求解目标函数,有效改善配电系统负荷的空间分布情况,为配电系统的安全、经济运行提供帮助。
