Battery energy storage system charging and discharging control method, device and equipment and storage medium

The invention relates to the technical field of energy storage system regulation and control, in particular to a charging and discharging control method, device and equipment for a battery energy storage system and a computer readable storage medium, and the charging and discharging control method for the battery energy storage system comprises the steps: obtaining a preset standing SOC; obtaining an absolute value of the working power of the battery energy storage system for charging and discharging and a first real-time SOC; according to the absolute value of the working power, determining the absolute value of adjusting power which is smaller than the absolute value of the working power; determining positive and negative values of working power; judging whether the first real-time SOC is smaller than the static SOC or not; if yes, the adjusting power is set to be a negative value; if not, the adjusting power is set to be a positive value; and controlling the battery energy storage system to charge and disc
