Research on Energy Router and Energy Management Strategy Based on Cyber-Physical Fusion

Abstract

In order to improve the friendly interaction and control ability of "source network load and storage" in distribution network, an AC-DC hybrid distribution network architectture based on multi-port energy router is proposed. The interface information is obtained by establishing the information physical model of each unit in the proposed architecture, and the system energy management scheme is designed. According to the designed energy management scheme, the coordinated control strategy of energy balance among distributed generation, energy storage system, distribution network and load is studied. The working mode and switching of the system are determined only by the interface information, without additional centralized controller, which improves the reliability of the system. Finally, MATLAB software was used to build a simulation platform to verify the effectiveness of the proposed DC hybrid distribution network energy router topology and energy management scheme.
