Power supply configuration method and device of power system

The invention discloses a power supply configuration method and device for a power system. The configuration method comprises the following steps: acquiring the comprehensive cost of a power supply and a target constraint condition; determining a power supply configuration model corresponding to the power system according to the comprehensive cost of the power supply and the target constraint condition; and processing the power supply configuration model to obtain a power supply configuration result of the power system. According to the power supply configuration method of the electric power system, the energy utilization rate can be improved, the reasonable charging and discharging state conversion times and the flexible charging and discharging power upper limit are set for energy storage, the maximum output and configuration capacity of the energy storage can be reduced, the economical efficiency of the system is improved, and the robustness of a planning result is guaranteed. 本发明公开一种电力系统电源配置方法及装置，其中配置方法包括
