Counter-current treatment method, system, device and medium for a three-phase power distribution network

Abstract

The application provides a reverse current processing method, system, device and medium of a three-phase power distribution network, belonging to the technical field of energy storage control. The method is applied to an energy storage system including multiple energy storage devices and a three-phase electric meter, control instructions are issued to the nth energy storage device based on a preset detection sequence to increase the output power; in the case that the nth energy storage device receives the control instructions, the power change data of each phase of the grid side is obtained through the three-phase electric meter, and the access phase corresponding to the nth energy storage device is determined based on the power change data; after determining the access phase of each energy storage device, if a reverse current signal is detected, the energy storage device with the access phase being the reverse current phase is selected based on the corresponding reverse current phase, the reverse current processing strategy is determined, and the operating parameters of the corresponding energy storage device are adjusted. The method realizes accurate identification of the access phase of multiple energy storage devices and reverse current positioning, reduces the phase misjudgment rate, and improves the operating stability and control efficiency in the home energy storage and grid connection scenario.
