一种V2G智能化能源管理的认证机制

Authentication Scheme for Smart Power Management Schemes in V2G

电动汽车在智能电网的发展中扮演了越来越重要的角色,电动汽车接入智能电网技术成为研究的热点问题。文章提出一种新的基于车联网技术的电动汽车接入电网通信系统模型。基于该模型,针对电动汽车接入电网中的能源管理及接入安全问题,提出一种智能化能源管理策略。与电网中传统的集中式能源管理策略不同,该策略基于车联网技术,将分布式的能源管理与集中式管理结合,使得能源供需信息在V2G网络中有效传播并快速匹配。基于新策略设计了电动汽车之间、电动汽车与聚合单元之间的安全认证机制和认证协议来保证智能能源管理策略有效安全服务电动汽车用户与智能电网。采用逻辑语言形式化地证明了新认证协议能够双向认证参与者的合法身份,能够保证电动汽车用户以及智能电网防御常见的网络攻击。

Electrical vehicles play more and more important roles in the development of smart grid. Vehicle-to-Grid technologies becomes a hot research issue. A novel VANET based V2 G communication model is proposed in this paper. In order to deal with the problem of power management and security of V2 G networks,smart power management schemes and secure authentication protocols for these schemes are proposed basing on the model for effective and secure service for electrical vehicles’ users and the security of smart grid. Based on VANET technologies, distributed and centralized strategies are combined in the proposed smart power management schemes, which is different with the traditional centralized strategy in power grid, so that charge and discharge requests can be effectively disseminated and matched in V2 G networks. Authentication schemes between electrical vehicles and aggregate units are designs to serve the electrical vehicle users and smart grid efficiently and safely.Logic language are used to prove the authentication for the smart management schemes can mutual authenticate the participants to prevent the electrical vehicles’ users and smart grid from network attacks.
