兼容分布式电源的直流配电系统运行控制技术
摘要
Abstract
This paper mainly explores the operation control technology of DC distribution system compatible with distributed power supply,in order to improve the voltage stability and operation reliability of DC distribution network.Taking the grid-connected interface of DC distribution system as the control object,three-phase VSC converter and DC/DC converter are designed in the grid-connected interface,both of which adopt the double closed-loop control strategy of current and voltage.Constant voltage and constant frequency control is adopted on the AC load side to meet the needs of DC distribution network to supply power to AC network.The simulation results show that the DC-side output voltage of VSC converter and DC/DC converter with grid-connected interface reaches the set value and remains stable after 1.5s start-up,and the dynamic response performance of the system is good;the amplitude and frequency of AC load side voltage are constant,and the output voltage of 220V AC is stable,which ensures the reliable operation of DC distribution system.关键词
