Electric Vehicle Peer-to-Peer Energy Trading Model Based on SMES and Blockchain

As the energy internet develops, it will become possible to carry out peer-to-peer energy trading among prosumers. Different from traditional commodity trading, the process of P2P electricity trading will be affected by physical constraints such as network congestion. To avoid transaction failure, a superconducting energy storage unit is introduced. First, we established the overall structure of the electric vehicle P2P energy trading, and designed the blockchain network and smart contracts; then analyze the benefits of each user entity in the system, and optimize the user matching in the transaction process; After that, we used the co-operative game algorithm to realize P2P electricity transaction pricing model. Finally, the simulation and analysis results show that the use of superconducting energy storage has effectively improved the success rate and demand consumption rate of electric vehicle P2P energy trading.
