Concentrator is the central connection device for linking terminals, computers or industrial communication device. As the result of the access to various information of energy storage equipment, such as Photovoltaic energy and electric vehicle charging piles, many challenges, which toward to communication speed and processing capacity of teminals, are emerging with the development of acquisition terminal. Based on the model view controller (MVC) programming mode, this paper takes the advantage of the edge computing technology to design a terminal service module for pluralistic load management. It endows the concentrator with terminal edge data interaction and intelligent processing capacities, and realizes load balancing management under the transformer.
