Blockchain Framework for Peer-to-Peer Energy Trading with Credit Rating

A peer-to-peer (P2P) energy trading market allows participants to trade their energy with each other directly. In this market, a pricing mechanism can regulate the trading price between traders and a scoring criterion could encourage participants good behaviors. This paper proposes a P2P energy trading model, including a blockchain framework to secure traders information and execute transactions, a two-level pricing mechanism to determine the trading price for each transaction and a credit rating system to improve the quality of the P2P market. The design of these methods to achieve their respective functions and the creation of blockchain are discussed in this paper. The results of a case study demonstrate the effectiveness of the proposed P2P trading model.
