Abstract
本申请公开了一种储能系统的电力调度方法及储能系统。其中，该方法包括：储能系统正常运行时，确定储能系统中各个第一电池簇的健康度与第一平均健康度的各个第一差值，其中，第二电池簇设置有DC / DC电压变换器与电池，DC / DC电压变换器与电池串联后接入储能系统，与第一电池簇并联使用；在各个第一差值小于第一限定值的情况下，获取储能系统中各个第一电池簇的电荷状态值与平均电荷状态值的各个第二差值；在各个第二差值小于第二限定值的情况下，获取功率转换器PCS的功率预定值，根据PCS的功率预定值调整第一电池簇的输出电流。本申请解决了由于不同电池簇的充放电速率不同造成的不同电池簇之间存在不同程度老化，且对延缓现象无法有效调整的技术问题。
