A reactive power scheduling method, device and equipment of an energy storage system and a storage medium

Abstract

This application provides a reactive power dispatching method, apparatus, device, and storage medium for an energy storage system, relating to the field of energy storage control technology. The specific technical solution is as follows: In response to an active power command, based on the state parameters of multiple energy storage units, the active power of the energy storage converter corresponding to each of the multiple energy storage units is determined; secondly, based on the total active power, a first compensation reactive power is determined to compensate for the reactive power loss of the leakage inductance of the primary winding of a multi-winding transformer; then, based on the active power of each energy storage converter, a second compensation reactive power is determined to compensate for the reactive power loss of the leakage inductance of the secondary winding connected to each energy storage converter; finally, based on the first compensation reactive power and the second compensation reactive power corresponding to each energy storage converter, a reactive power dispatching command is issued to each energy storage converter. This application can effectively reduce the interference of active power dispatching on the reactive power of the multi-winding transformer side and improve the operational stability of the energy storage system.
