Abstract Energy router is an important part of the energy interface between home regional energy network and power grid. Aiming at an AC/DC household energy router structure, this paper studies and designs the energy balance coordination control strategy between distributed generation, energy storage system, power grid and load. To extend the battery life in the hybrid energy storage system composed of batteries and supercapacitors, fuzzy control algorithms and power management strategies are designed. The improved droop control strategy is adopted to realize the smooth switching of household energy router when connected to the grid, and improve the robustness of the system. The home energy router simulation model is established and analyzed on the Matlab/Simulink platform. The simulation results show that the control strategy studied in this paper can effectively restrain the influence of renewable energy output fluctuations and load changes while maintaining the stability of the system.
