Embodiment Construction

[0057] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0058] Such as figure 1 As shown, the power trading method proposed by the present invention includes the following steps:

[0059] Step S1. Obtain an initial transaction plan.

[0060] Among them, the trading plan includes electricity sales table, electricity price table, electricity consumption table and line transmission price table. The electricity sales volume table records the expected electricity sales volume of each seller to each consumer, the electricity sales table records the expected electricity sales price of each seller to each consumer, and the electricity consumption table records the expected electricity sales price of each consumer. The expected electricity consumption of each seller, and the line transmission price table records the transm...

Abstract

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 evaluation model, and if the evaluation is passed, taking the current transaction scheme as an actual transaction scheme; otherwise, repeating the steps S2 and S3. And global revenue maximization can be realized. The invention also provides a point-to-point power transaction system.

Description

technical field [0001] The invention relates to the technical field of power trading, in particular to a point-to-point power trading method and system based on a consistent ADMM algorithm. Background technique [0002] Renewable energy power generation is gradually favored due to its advantages of sustainability, pollution-free, and low cost. However, due to the inherent uncertainty of renewable energy power generation, its access brings severe challenges to the stable and safe operation of the power grid. The uncertainty of renewable energy power generation is mainly absorbed by designing a reasonable power trading mechanism to optimize demand response. [0003] Electricity trading usually takes producers and consumers as the main body, trades electricity through negotiation and bidding, and determines the price and quantity through market competition. If the power trading is properly designed, the efficiency will be greatly improved, the investment planning will be more ...
