In order to accelerate the construction of energy internet, the research on its core device, energy router, is of great significance. According to a demonstration project of distributed energy in Zhejiang, the research and commissioning of microgrid system based on multi-port energy router is developed. This paper expounds the topological structure of five-port bi-directional energy router in this project, and builds microgrid system including distributed photovoltaic power, energy storage device and smart house which is self-sufficiency. During the debugging process, the output side DC bus voltage fluctuations of energy router was suppressed as well as the issue that output of photovoltaic power could not be sent to energy router was fixed by coordinating the technical parameters and control strategy of DC/DCs. Energy router keeps power balance of each port and voltage stabilization of DC bus, which ensure the microgrid runs safely and reliably. The debugging result validate the validity and rationality of microgrid system based on multi-port energy router, and its debugging optimization process has guiding significance for practical engineering application of multi-port energy router in the future.
