Battery energy storage grid-load interactive method, terminal, system and medium for superimposed control

A battery energy storage grid-load interactive terminal, comprising:

• a processor;
• and
• a memory for storing instructions executable by the processor,
• wherein the processor is configured to:
• receive a load shedding instruction sent by a master station;
• send the load shedding instruction to the power conversion system to enable the power conversion system to switch an operating state of the power conversion system from a charging state or a standby state or a discharging state to a maximum power discharging state according to the load shedding instruction;
• and
• send the load shedding instruction to the energy managing system to enable the energy managing system to control the power conversion system in one manner of a group consisting of:
• controlling, by the energy managing system, the operating state of the power conversion system to switch from the maximum power discharging state to an optimal power discharging state;
• acquiring, by the energy managing system, the power conversion system failing to switch the operating state, and controlling the operating state of the power conversion system failing to switch the operating state from the charging state or the standby state or the discharging state to the maximum power discharging state;
• and
• maintaining, by the energy managing system, the operating state of the power conversion system unchanged.
