For the access of distributed power sources and the effective management of electric energy, energy routers with highly flexible power control and information interaction functions were applied to low-voltage distribution networks to achieve integrated operation of source-network-load-storage, thereby improving load regulation capabilities and new energy consumption levels, and ensuring the stable operation of the power system. Therefore, A household energy router for low-voltage distribution network application was designed, and its topology and power coordination control strategy were studied based on the characteristics of each port application object to provide a reliable energy management strategy for power production and consumption. Finally, a simulation model based on MATLAB/Simulink was established to verify its power coordination control strategy. The simulation results show that the proposed multi-port energy router power coordination control strategy can achieve power reciprocity and system power balance control between different ports under various operating modes, and has high flexibility, stability and reliability in energy management.
