柔直与光储混联主动配电系统研究及应用

Research and application of flexible and optical storage hybrid active distribution system

柔直与光储混联主动配电系统是针对徐州配电网目前面临的问题,通过柔直变流器对原有低压结构进行改造,建立直流可合环运行的四端口网络,同时在直流母线上配置光伏、储能和充电桩等分布式电源以实现光伏与储能互补,形成一套低压配网供用电新模式。

The flexible direct and optical storage hybrid active distribution system is aimed at the current problems faced by Xuzhou distribution network.The original low-voltage structure is transformed by flexible direct converter,and a four-port network with closed-loop DC operation is established.At the same time,the distributed power sources such as photovoltaic,energy storage and charging piles are installed on the DC bus to realize the complementary of photovoltaic and energy storage,thus forming a set of new mode of low-voltage distribution network for power supply and consumption..
