Design of V2G auxiliary service system based on 5G technology

In order to deal with the existing deficiencies of V2G communication in auxiliary service system, which is reflected in bandwidth, delay, reliability, safety and mobility, etc., this paper propose to apply 5G technology into the system. At first, we analyzed the communication requirement and the communication technology in V2G system. After that, we designed the overall system architecture and information transferring process, both based on 5G technology. The process consists of the V2G service connection process initiated by EV, the V2G service connection process initiated by V2G server and the aggregator registration updating process switched by EV. The 5G-based V2G system we proposed can satisfy the requirement on wireless communication network, and hence can improve the integration of renewable energy into the grid and finally improve the economic and environmental efficiency of the grid, with all these improvements under a safe and reliable grid.
