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

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 t
