Review of Market Clearing Method for Blockchain-Based P2P Energy Trading in Microgrid

The peer-to-peer (P2P) energy trading creates a platform for all microgrid users to exchange their energy surplus and demand without the presence of a centralized authority. With P2P, the dynamic electricity market between nodes will be developed, thus increasing the overall throughput of the microgrid. To ensure the energy transactions in local energy trading meet the highest level of integrity, the blockchain system is implemented. Appropriate classification and structuring the literature on viable designs for local energy trading can assist researchers in effectively developing their subsequent planning for the local energy market. This study reviews the current research related to market clearing methods for blockchain-based P2P energy trading for microgrid system. The focus is on the auction theory, constrained optimization, game theory and agent methods.
