摘要
介绍了直流微电网的运行原理,设计了直流微电网控制系统,给出了控制系统的三层结构。分析了直流微电网稳定运行的停运、并网和离网模式,以及过渡过程。直流微电网控制系统采用变流器控制,具有储能控制、光伏控制、风电控制、负荷控制、一键启动和同期并网等功能,控制效果良好。
The operating principle of DC microgrid was introduced,the DC microgrid control system was designed,and the three-layer structure of DC microgrid control system was given.The out of operation,on-grid and off-grid modes of the stable operation of the DC microgrid,and the transition process were analyzed.The DC microgrid control system is controlled by converter,and has the functions of energy storage control,photovoltaic control,wind power control,load control,one-button start and synchronous grid connection,and the control performance is in condition.
