Electric vehicle charging electric energy transaction method based on block chain technology

Abstract

The invention relates to an electric vehicle charging electric energy transaction method based on a block chain technology. The method comprises the steps of designing an electric vehicle charging electric energy transaction market interaction mode and a decentralized transaction platform based on a block chain storage technology; the power distribution network establishes an optimal power flow model and a blocking management model according to the historical load data of the charging station, and calculates the marginal electricity price of power distribution network nodes; the charging station establishes an ordered charging scheduling model, formulates a day-ahead electric energy plan according to the marginal electricity price of the power distribution network node, and achieves a day-ahead electricity purchasing intelligent contract with the power distribution network through the decentralized transaction platform; the charging station customizes the charging cost for the electricvehicle user according to the real-time charging demand of the electric vehicle user, and guides the electric vehicle user to charge orderly through a charging recommendation strategy; and an electric vehicle user signs a charging service intelligent contract with the charging station through the decentralized transaction platform. The method improves the fairness of electric energy transaction of the electric vehicle, reduces the charging cost, and guarantees the safe and economic operation of a power system.

Description

technical field [0001] The invention belongs to the technical field of electric power market, and in particular relates to a method for trading electric vehicle charging electric energy based on block chain technology. Background technique [0002] With the electrification of transportation, the number of electric vehicles is growing rapidly. The access of a large number of charging loads is bound to have a great impact on the distribution network. The development of the electricity market has made it a feasible solution to orderly dispatch the charging power of charging stations through market-oriented mechanisms. In the electricity market environment, electric vehicles, charging stations / piles, and power grids belong to different stakeholders. Electric vehicles need to meet the travel needs of users, and charging stations / piles, as charging service providers, will pursue the maximization of their own interests. The power grid needs to ensure safe, cost-effective and effi...

AI Technical Summary

Problems solved by technology

[0003] At present, the research on the interaction of electric vehicle charging energy trading mainly focuses on the orderly charging behavior under the "vehicle-network" interaction mode dominated by the power grid, without considering the multi-level interaction of "vehicle-pile-network" under the market equal subject transaction mode.
