Abstract

本申请提供一种储能系统，该储能系统中包括一个或者多个储能单元簇，储能单元簇由至少两个储能模组串联组成。储能系统还包括第一母线、第二母线和储能单元簇的集中监控系统，第二母线为直流母线。储能单元簇通过第一变换器耦合到第一母线，一个储能模组中包括一个储能元件组和一个DC/DC变换器，储能元件组通过DC/DC变换器耦合到第二母线。集中监控系统通过控制总线连接上述储能单元簇，用于控制储能单元簇中任一储能模组中的DC/DC变换器输出补偿电流至储能元件组端或者从储能元件组端抽取电流，以使各储能模组的储能元件参数一致。本申请提供的储能系统，可提高储能系统中各储能模组的控制灵活性，增强储能系统的管理有效性。
