摘　　要：为了更好地协调和控制以家庭为单位的户级直流微网的能量传输,提出一种户用型能量路由器及相应控制策略。能量路由器根据各端口的就地信息和内部直流母线电压大小工作在不同层区,在所提控制策略下实现了各个层区之间的无缝切换和对能量的协调管理。针对能量路由器的储能端口,引入超级电容器和蓄电池的混合储能,延长电池使用寿命,实现系统稳定运行。最后在MATLAB/Simulink平台上搭建能量路由器系统,对控制方法进行系统仿真,验证了所提控制策略的正确性。In order to better coordinate and control the energy transmission of the household-level DC microgrid system,a household energy router is proposed and its control strategy is analyzed.Under the proposed control strategy,the energy router realizes seamless switching between various layers and coordinated management according to the local information of each port operating in different states and the internal DC bus voltage division.For the energy storage port of the energy router,the supercapacitor and the battery are combined to hybrid energy storage,which prolongs the service life of the battery and realizes stable operation of the system.Finally,the energy router system is built on MATLAB/Simulink platform tocarry out system simulation of the control method and verify the correctness of the proposed control strategy.
