Abstract

To coordinate off-grid control of the Energy Router, the Energy Router topology is first analyzed using isolated bidirectional full-bridge DC/DC inverters for DC ports, boost converters for PV units, and three-phase voltage-based bridge inverters for AC ports. Then the system is layered, with the lower layer developing different control strategies for different ports, the upper layer layering the DC bus voltage and dividing different operating modes in combination with the energy storage SOC, and then developing strategies for each mode. Finally, simulations are built in the MATLAB platform according to the topology to verify the possibility of off-grid operation of the energy router.
