A Multi-Factor Reputation Management Approach Integrated with Blockchain for Smart Grid 2.0

Smart Grid 2.0 underscores the need for a robust and secure reputation management system to instate trust in energy transactions while improving efficiency in grid operation, maintaining sustainable energy usage practices, and improving network capacity utilization. This paper proposes a multifactor reputation scoring system, integrating factors directly reflecting individual behaviour and factors whose cumulative impact considering similar users, affects the grid operations. The proposed multi-factor reputation management framework for Peer-to-Peer energy trading is validated through tests, which indicate the correlation of the factors assessed in computing the reputation score. The algorithm is further deployed on the Sepolia blockchain test network to evaluate the associated transaction latency, which resulted in an average of $14 s$.
