Power scheduling optimization method and system for multi-cluster SOC equalization in mobile energy storage and charging systems

Abstract

This invention relates to the field of power dispatching technology in power systems, and discloses a power dispatching optimization method and system for balancing the SOC of multiple clusters in a mobile energy storage and charging system. The method includes: non-parallel energy storage battery clusters connected to charging guns on charging piles via DC coupling; the charging piles using a flexible power dispatching system; real-time acquisition of state parameters and charging demand parameters for all energy storage battery clusters; calculation of a priority score for each energy storage battery cluster based on the state parameters, including the SOC, SOH, and temperature of the energy storage battery cluster; selection of energy storage battery clusters for charging piles based on the charging demand parameters and priority scores; and allocation of discharge power to the selected energy storage battery clusters based on the objective of equal SOC after charging completion as a dispatching weight factor. This invention can balance the SOC of each battery cluster in a mobile energy storage and charging system, extending battery life and improving system efficiency.
