The energy router is a core device in the field of the energy internet, and its circuit topology enables unified distribution of new energy sources, energy storage, and various loads. Currently, energy routers lack the capability to restore power distribution networks after faults. A multi-port energy router (MP-ER) is proposed in this paper, which achieves fault regulation and new energy accommodation. Firstly, the topology and principles of the MP-ER are introduced, and based on its overall structure, a control strategy is proposed that utilizes the DC bus voltage as the primary signal and implements decentralized control for each port. Secondly, by considering the DC bus voltage and the zero-sequence voltage of the distribution network, the operating modes of the MP-ER are divided into normal mode and fault-tolerant flexible arc suppression mode. Under the proposed control strategy, stable and efficient operation is achieved within each mode. Finally, for the connected microgrid and distribution network systems, MATLAB numerical software is used to simulate the model and verify the rationality of the proposed topology and its functions. This research introduces a new topology and model for the study of energy routers.
