Abstract

A robust and secure reputation management system is required to ensure reliability, trust, and efficiency in energy transactions. This paper proposes a multi-parameter reputation scoring system, which enables combining factors that reflect direct individual performance, and the contribution towards maintaining a stable grid and delivering a high-quality power supply. Further, this study proposes integrating blockchain for the realization of the reputation management of Smart Grid 2.0. This ensures a secure and transparent mechanism, eliminating data poisoning and repudiation of transactions. Smart contracts facilitate the automatic execution of data aggregation, reputation calculation, and selective decision-making processes. The performance of a multi-factor reputation management scheme on Peer-to-Peer energy trading is evaluated through the conducted tests. The superiority has been showcased through benefits to the consumer and the prosumer. Moreover, a comparison against the state-of-the-art reputation scheme is included to further highlight the significance of this study.
