Research on Vehicle-pile-Grid Interconnection and Interaction Technology

Due to the imminent energy crisis, electric vehicles have developed rapidly under various policies and financial support, and their number has increased dramatically in recent years. Although EVs have alleviated the non-renewable energy tension and environmental pollution problems to a certain extent, the large number of EV clusters charging and discharging has posed a serious challenge to the carrying capacity of the power grid. To address the problem of uneven grid load curve, this paper analyzes the possible effects of interconnection and information interaction and sharing among EVs, charging piles and the grid to solve the power tension problem, and mentions possible vehicle pile-grid interconnection approaches and architectures, as well as some potential future applications of V2G technology at the intersection of EVs and intelligent transportation.
