A Energy Security Trading Scheme for Electric Vehicles based on
Blockchain and Trust Mechanism
AbstractMore and more people choose to use electric vehicles to protect the
environment and conform to the trend of sustainable development.
However, the increase in the number of electric vehicles may cause
problems with the overload of the grid, and electric vehicles have their
shortcomings of weak range. Vehicle-to-vehicle energy trading can
balance the load on the grid and alleviate the range anxiety of electric
vehicles. Existing studies focus more on transaction efficiency and
energy utilization, ignoring data security and user privacy during the
transaction process. To this end, this paper proposes a blockchain-based
V2V energy security transaction scheme, which records the data of the
transaction process on the blockchain, and realizes the registration,
authentication, and transaction process through smart contracts.
Furthermore, we propose a transaction matching scheme, which fully
accounts for both parties' credibility and uses the Bayesian game to
determine the transaction price. Under the premise of an incomplete
exchange of information, both parties shall ensure the reliability of
the transaction and obtain the optimal price. Finally, the algorithm
performance is evaluated through simulation, which shows that the scheme
is close to the bidding price of both parties, and the high user
satisfaction ensures a higher matching success rate for both parties.
Considering the trust value matching and pricing scheme can be a good
way to limit the behavior of both sides of the transaction, and ensure
the credibility of both sides and the security of the transaction.
