Regional electric vehicle alliance electric power transaction method based on block chain

Abstract

The invention relates to a regional electric vehicle alliance electric power transaction method based on a block chain, and belongs to the technical field of electric vehicles. In order to solve the problem of mileage anxiety encountered in the driving process of electric vehicles, the invention provides a regional electric vehicle alliance V2V joining matching strategy, and a decentralized consensus mechanism is designed for a V2V power transaction platform by using a block chain technology. A simulation result shows that the V2V electric power transaction alliance can effectively meet the emergency charging demand of an electric vehicle user in the driving process, and a proposed electric power transaction strategy can realize the optimal charging and discharging matching transaction between electric vehicles; the earnings obtained by the block chain system can cover the cost of computing power required for using the block chain, and economic feasibility is achieved; and in the load peak period, compared with the electric vehicles accessed to the network, the electric vehicles participating in the V2V transaction can obtain more profits.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles and relates to a blockchain-based regional electric vehicle alliance power trading method. Background technique [0002] In recent years, vehicle-to-vehicle (V2V) electricity trading has been proposed and widely studied as a novel and flexible charging mode. Based on the advantages of electric vehicles, the cooperation between vehicles is strengthened to extend the mileage and effectively avoid the grid overload problem. As a new charging method, power transmission between electric vehicles can form a good complement to the V2G charging mode of electric vehicles, thereby alleviating users' mileage anxiety. Electric vehicles can conduct electricity transactions through intermediate energy service providers, and can also independently convert electric energy through two-way chargers. It is often more cost-effective to directly trade energy between electric vehicles that are in urgent nee...

Problems solved by technology

There are many trading entities involved in the Internet of Vehicles and the transactions are scattered. If the traditional centralized trading model is adopted, three problems will arise: first, the operation cost of the control center is high, the operation efficiency is low, and decision-making takes a long time; There are trust issues between cars, and it is difficult to guarantee fairness, transparency, and information symmetry; third, the central organization is likely to cause information security risks, endangering transaction security and the privacy security of participants
