Research on communication network architecture of energy internet based on SDN

In this paper, we use software defined network (SDN) technology characteristic of forwarding separating and control to concentrate the control functions in the control layer (comprised by SDN controllers), and design a kind of communication network architecture for energy interconnection. Firstly, we give the concept of Intelligent Energy Controller (IEC), and make it as a device to arrange underlying network information and implement commands from upper layer. Then, we describe the architecture and running process of the system, by introducing in detail the design of the architecture and the flow process of information in the network. In the end, we analyze the benefits and hidden dangers to reveal the advantages and disadvantages, of the architecture, which can provide a reference to related research.
