Research on energy trading method of smart grid P2P blockchain considering benefit maximization

In the smart grid, customers with renewable energy generation equipment can trade energy with others for a profit. Users with insufficient self-generated energy can meet their needs by purchasing the energy they need from other users who have surplus energy. However, users are reluctant to participate in such transactions if they do not generate additional revenue for them. In order to improve the revenue of energy trading participants, this paper proposes a new perer to perer (P2P) energy trading approach. Energy trading is described as a non-cooperative game between energy generators and consumers and auctioneers. The buyer adjusts the amount of energy purchased according to different tariffs, the auctioneer controls the game, and the seller does not participate in the game, but ultimately maximizes the benefits. Then, the existence of a unique game equilibrium is proved to determine the market energy trading price and quantity. The proposed energy trading method is implemented through using blockchain technology to show the feasibility of real-time P2P energy trading. Simulation results show that the cumulative efficiency of the participants of the proposed method is improved by more than 32% compared to two existing methods, which verifies its effectiveness.
