Secure and incentivized V2G Participation with blockchain and game theory

Abstract

The vehicle-to-grid (V2G) network is a transformative technology that enables electric vehicles (EVs) to interact with the power grid, enhancing grid stability and promoting the integration of renewable energy. This paper presents a secure and efficient V2G framework addressing key challenges, such as optimizing energy management and ensuring robust security. The proposed framework incorporates game theory-based scheduling for optimal EV charging and discharging, mutual authentication using ECC keys and hash functions for secure communication, and blockchain technology for transparent and tamper-proof data management. Experimental results demonstrate the framework's effectiveness in balancing the supply and demand of energy between EVs and the grid, optimizing production-consumption ratios, and improving grid interaction efficiency. The approach also enhances the economic benefits of V2G operations, improving EV selection probability and net utility, and demonstrating superior performance compared to existing techniques. These results highlight the framework's potential for secure, efficient, and cost-effective V2G integration.
