A distributed energy storage system and group control method thereof

Abstract

A distributed energy storage system and a group control method thereof are provided. The distributed energy storage system comprises an electric meter, a main controller, a plurality of slave controllers and a plurality of energy storage systems. The main controller is connected with the plurality of slave controllers. The plurality of slave controllers are connected with the plurality of energy storage systems one to one. The electric meter acquires the load power value of a power grid. The main controller reads the load power value stored in the electric meter, obtains the output power specification of the distributed energy storage system, and obtains a calculated power value according to the load power value and the output power specification to determine whether a local load satisfiesa discharged condition. If the local load satisfies the discharged condition, the main controller sends a control signal to a preset number of slave controls according to the calculated power value.The slave controllers control the corresponding energy storage system to start work according to the control signal to discharge the local load. Under the centralized control of the main controller, the power supply states of the plurality of energy storage systems are intelligently adjusted according to the change of the power consumption of the local load.
