电能路由器是能源互联网的关键设备,为实现电能路由器功能要求,提出一种基于双直流母线架构的电能路由器.通过低压直流母线和高压直流母线,以多种端口形式将光伏、储能、交流电网、交直流负荷等进行互联,分析研究了电能路由器的工作模式和各端口变流器的控制方法,提出电能路由器内部的协调控制策略、负载侧主动响应指标和控制策略,实现功率双向流动控制、端口电压稳定和供用路由选择多样化.仿真研究中,设置了3种场景案例进行试验和分析,结果表明所提出的电能路由器能实现功率路由分配、系统稳定运行和端口即插即用等功能,为电能路由器的实现提供了新思路.%Power router is the key equipment of the energy Internet. In order to realize the function requirement of the power router,this paper proposes an power router based on the double DC bus structure. Through the low voltage DC bus and high voltage DC bus,with the interconnection of photovoltaic,energy storage,AC power grid,and AC/DC load in the form of multiport, we analyze the operation mode of the power router and the control methods of port converters, put forward the internal coordination control strategy of power router, the active response index of lateral load and the control strategy,which can realize the two-way power flow control,the port voltage stability and the selection diversification of use router. In the simulation study,three case scenarios are tested and analyzed. The results show that the proposed power router can realize the functions of power router allocation,the stable operation of the system and the plug and play of port,which can provide new ideas for the power router implementation.
