Abstract

In the networked enlarged electric vehicle (EV) charging infrastructures, the security and authenticity of the stakeholders involved in the EV energy market pool are prime important. This paper proposes an EV network hub (EVNH) comprising EVs, EV aggregators (EVAs), and charging nodes in the networked EV energy market pool. The various EVAs implement different heterogeneous blockchains. The EVNH facilitates blockchain-based secure and resilient energy trading under grid to vehicle and vehicle to grid systems. The paper emphasizes interoperability challenges involving different blockchains to communicate and transfer assets or data between them. We suggest secure and trustworthy energy trading across various EVAs using multiple EV tokens for EV energy trading through cross-chain communications. The EVAs consider a Nash equilibrium-seeking strategy to find the Nash equilibrium in the noncooperative game of EVAs. The effectiveness of the proposed EVNH is tested using MATLAB, Solidity, and Python software.

电动汽车充电站异构网络集线器的区块链安全和真实纳什均衡策略

在网络化的大型电动汽车充电基础设施中，电动汽车能源市场池中利益相关者的安全性和真实性至关重要。本文提出了一种由电动汽车、电动汽车聚合器和充电节点组成的电动汽车网络集线器（EVNH）。各种eva实现不同的异构区块链。EVNH促进了电网到车辆和车辆到电网系统下基于区块链的安全和弹性能源交易。本文强调了涉及不同区块链之间通信和传输资产或数据的互操作性挑战。我们建议通过跨链通信使用多个EV令牌进行EV能源交易，从而在各种EV之间进行安全可靠的能源交易。在EVAs的非合作博弈中，EVAs考虑纳什均衡寻求策略来寻找Nash均衡。使用MATLAB、Solidity和Python软件对所提出的EVNH的有效性进行了测试。
