电动汽车大规模接入电网给电力系统的稳定运行带来了挑战,电动汽车与电网互动(Vehicle to Grid,V2G)能为电动汽车的有序充电提供技术支持。作为一种交通工具,当处于行驶状态的电动汽车有充电需求时,其充电时间和地点并不能完全事先确定。本文研究电动汽车充电预约的信息安全问题,在融合智能电网与车联网的基础之上,基于端、边、管、云的通信系统逻辑架构,利用改进DSA数字签名的批验证技术,提出了一种应用于行驶状态的电动汽车充电预约安全认证方案,性能分析结果验证了所提方案的有效性。
英文摘要:
The large-scale integration of electric vehicles into the power grid has brought challenges to the stable operation of the power system. However, Vehicle to Grid (V2G) network can be employed for the orderly charging management of electric vehicles. When an on-the-move electric vehicle need a recharging service, when and where to be recharged cannot be determined in advance. This paper deals with the issues of information security for an on-the-move electric vehicle charging reservation, where the VANET-enhanced smart grid is considered. Based on the logic hierarchy of end, access network, edge, core network and cloud of the proposed communication system, and by utilizing the batch verification of the improved DSA digital signature, an authenticated electric vehicle charging reservation scheme is proposed, where the VANET are incorporated. Performance analysis. And the effectiveness of the proposed scheme is also verified.
