A Novel Pricing Scheme for Peer-to-Peer Energy Trading Based on Evaluation Mechanism in Microgrid

Power marketization can revert the property of electricity commodities and improve the efficiency of resource allocation. In this area，making an effective pricing scheme remains a particular challenge. In this paper, a novel pricing scheme based on evaluation mechanism is proposed, which provide a market-oriented scheme for driving peer-to-peer (P2P) energy trading and optimizing prospective earnings for all households in the microgrid. The evaluation mechanism as a feedback on the historical energy service level of households can make them with better evaluation coefficient have more advantages in optimal quotation point (OQP) and improve the efficiency of the electricity market. Furthermore, the proposed scheme is applied to simulate, and according to the simulation results, the more bidders participate in the auction, the less the prospective earnings are. In addition, when the number of bidders is same, the lower evaluation coefficient, the higher prospective earnings.
