Abstract: P2P transactions are a new transaction mode suitable for distributed electricity prosumers participating in the electricity market. Considering the economic benefits to prosumers and the local consumption of distributed clean energy, a P2P electricity transaction process was developed based on a double-round bidding game, and a game model with the goals of economic benefit and clearing energy was established. An example analysis was conducted for a community with different types of distributed electricity prosumers such as residents, offices, and commerce. Compared with continuous bilateral auctions, one-round bidding games, and P2G, the results of P2P transactions with a double-round bidding game showed that economic benefits increased by 19.01%, 28.78%, and 56.81%, and the local consumption rate of distributed clean energy increased by 10.51%, 24.05%, and 85.10%, respectively. In conclusion, adopting a bidding method and strategy can increase the revenue of distributed electricity prosumers, improve the efficiency of P2P transactions, promote the local consumption of distributed clean energy, and help realize the “double carbon” goal.
