Abrégé
(EN)
An embodiment of the invention discloses a superposition controlled battery energy storage network load interaction method, a battery energy storage network load interaction terminal, a superpositioncontrolled battery energy storage network load interaction system and a medium. The superposition controlled battery energy storage network load interaction method comprises the steps that the batteryenergy storage network load interaction terminal receives a load shedding instruction transmitted by a main station, the battery energy storage network load interaction terminal transmits the load shedding instruction to a power conversion system, so that an operating state of the power conversion system is switched from a charging state, a standby state or a discharging state to a maximum powerdischarging state according to the load shedding instruction, and the battery energy storage network load interaction terminal transmits the load shedding instruction to an energy management system toenable the energy management system to control the power conversion system. The superposition controlled battery energy storage network load interaction method realizes the effects of switching the operating state of the power conversion system from the charging state, the standby state or the discharging state to the maximum power discharging state at the fastest speed, ensuring the minimum delay of state switching, and transmitting the load shedding instruction to the energy management system to realize safe takeover of source network load control.
