Design and Implementation of Multi-port Energy Routers Towards Future Energy Internet

This paper presents a AC/DC hybrid system constructed by multi-port energy routers, which have potential applications for power consumers in distribution power system. It is easy for the selected main circuits to realize high reliable and multiple forms of power supply, plug-and-play access of distributed power supply, and high expansibility of power ports. The corresponding control and protection systems are developed to ensure the regular operation of energy routers, and smart energy management scheme is presented to satisfy expectations of power consumers. Two experimental prototypes are implemented, of which the experimental results validate the parameter design and show the satisfactory functions, demonstrating that the presented multi-port energy routers are very promising for the future energy Internet construction.
