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.
