Charging and discharging power regulation and control algorithm and device based on load following and prediction

The invention provides a charge and discharge power regulation and control algorithm and device based on load following and prediction. The device comprises a cloud platform, an energy storage system and a power distribution system. The power distribution system is connected with the state grid; the power distribution system is provided with a transformer; the energy storage system is connected with the power distribution system through a cable; the cloud platform is connected with the energy storage system and the power distribution system through a gateway; according to the method, the battery is charged in the off-peak period of the power grid, and the energy storage system is discharged in the peak period, so that the power utilization cost is saved. Meanwhile, in a charging and discharging strategy, the energy storage cabinet is set to be charged during valley power and level power and discharged during peak power according to local peak-valley normal time segments, so that peak-valley arbitrage of the e
