Point-to-point electricity transaction method and system based on consistency ADMM algorithm

The invention provides a point-to-point electricity transaction method. The point-to-point electricity transaction method comprises the steps of S1, acquiring an initial transaction scheme; s2, inputting the last transaction scheme into the sales volume updating model to obtain a current electricity sales volume table; inputting the last transaction scheme into the consumption update model to obtain a current power consumption table; inputting the current power sale scale, the current power consumption table and the last power sale price table into a sale price updating model to obtain a current power sale price table; inputting the current power sales scale into the power flow model to obtain the power flow on each line; updating the power transmission price of the target line exceeding the line power flow constraint condition according to a line price updating model, and obtaining the transportation price of the current target line; s3, inputting the current transaction scheme into the transaction evaluatio
