微电网在孤岛运行状态下储能变流器输出电压、频率不稳定和有功、无功功率不平衡,变流器传统的下垂控制不能对微电网孤岛运行的电压和频率进行无静差调节,且无法满足微电网孤岛运行的有功、无功功率平衡。基于此,提出一种多储能变流器分...展开更多 微电网在孤岛运行状态下储能变流器输出电压、频率不稳定和有功、无功功率不平衡,变流器传统的下垂控制不能对微电网孤岛运行的电压和频率进行无静差调节,且无法满足微电网孤岛运行的有功、无功功率平衡。基于此,提出一种多储能变流器分层协同控制方法。在综合考虑储能变流器运行控制目标和微电网相邻储能变流器信息交换的基础上,设计微电网分层互联...

The output voltage and frequency of energy storage inverters in microgrids are unstable and the active and reactive power are unbalanced under islanded operation.The traditional droop control of inverters cannot adjust the voltage and frequency of microgrid islanded ope...MORE The output voltage and frequency of energy storage inverters in microgrids are unstable and the active and reactive power are unbalanced under islanded operation.The traditional droop control of inverters cannot adjust the voltage and frequency of microgrid islanded operation without static error,and can not meet the act...
