The invention relates to a power supply scheduling method and device, a power supply system and a storage medium. The power supply scheduling method comprises the following steps: in the process of supplying power to a charging station by a power distribution network, obtaining the current power grid capacity of the power distribution network, the current demand load of the charging station and the current power supply capacity provided by the power distribution network to the charging station; when the current power grid capacity is greater than the preset power grid capacity, controlling the power distribution network to reduce the power supply capacity of the charging station according to a first load difference value between the current power grid capacity and the preset power grid capacity; and controlling an energy storage device to supply power to the charging station according to the reduction result of the power supply capacity, the current power supply capacity and the current demand load. The power supply scheduling method can reduce the charging time of the electric vehicle when the power distribution network is in the power utilization peak.
Description
technical field [0001] The present application relates to the field of electric power technology, in particular to a power supply scheduling method, device, power supply system and storage medium. Background technique [0002] The whole composed of substations of various voltages and transmission and distribution lines in the power system is called the power grid. The power grid consists of three units: transformation, transmission, and distribution. The task of the distribution network is to transmit and distribute electric energy and change the voltage. [0003] At present, when an electric vehicle needs to be charged, it needs to go to the charging station for charging, and then leave the charging station after the charging is completed, and the power source of the charging station is the electric energy transmitted and distributed by the distribution network. [0004] However, charging times for EVs are longer when the distribution network is at peak power consumption....
