A Power Sharing Method Based on SOC Unbalanced Degree for Energy Storage Equipment

储能装置中储能单元之间合理的功率分配对其高效可靠运行和使用寿命的延长至关重要。提出了一种基于荷电状态(SOC)不平衡度的功率分配方法,该方法引入了SOC不平衡度算法并构建了SOC不平衡度对角阵,通过与SOC不平衡度阈值的比较得到合理的功率分配指令,最终实现了储能装置SOC及输出功率的均衡。仿真和实验结果验证了所提方法的可行性和有效性。

Reasonable power sharing is essential to the efficient and reliable operation of energy storage equipment and the extension of the service life.A power sharing method based on the state of charge（SOC） unbalanced degree is proposed.This method defines the SOC unbalanced degree algorithm and constructs the SOC unbalanced degree diagonal matrix, and the reasonable power allocation is obtained by comparing with the threshold of the SOC unbalanced degree, and finally the SOC and output power of the energy storage equipment is balanced.Simulation and experimental results are presented to verify the feasibility and effectiveness of the proposed method.
