Distributed trading scheme for vehicular grid interaction supporting transaction anonymity and credit management

Abstract

To address the significant challenge of supply-demand balance in the power system and better coordinate the energy and information interaction between electric vehicles and smart grids, vehicular grid interaction has been extensively studied. Blockchain technology has the characteristics of decentralization, openness, and non-tamperability, which is naturally suitable for distributed transactions with virtual power plants. However, the current distributed energy transactions of virtual power plants face challenges in credit management and privacy protection, which are not conducive to the stability of the trading market. To address the above issues, this paper proposes a blockchain-based distributed energy trading scheme for virtual power plants, which realizes distributed trading while protecting the user’s identity information and providing credit management for the user’s performance behaviour. Finally, the performance evaluation and security analysis of the scheme based on security and privacy requirements show that the scheme is both secure and practical.
