Charging and discharging strategy determination method for centralized energy storage and storage medium

The invention relates to a centralized energy storage charging and discharging strategy determination method and a storage medium. The method comprises the following steps: acquiring a day-ahead prediction curve and a real-time output curve corresponding to a power system within a preset time period; determining a day-ahead charging and discharging plan of centralized energy storage in the preset time period according to the day-ahead prediction curve; and according to the real-time output curve and the day-ahead charging and discharging plan of the centralized energy storage in the preset time period, determining an intra-day charging and discharging strategy of the centralized energy storage in the preset time period. According to the technical scheme provided by the invention, the capability of adjusting the power balance of the power system by the energy storage is improved, the battery loss of the energy storage is reduced, and the service life is prolonged. 本发明涉及一种集中式储能的充放电策略确定方法及存储介质，所述方法包括：获取预设时段内电力系统
