P2P energy transaction method based on block chain and multi-objective decision

Abstract

The invention discloses a P2P energy transaction method based on a block chain and a multi-objective decision, and the method comprises the following steps: S1, enabling an electricity selling / purchasing user to submit electricity selling / purchasing information and an electricity selling / purchasing matching requirement on the block chain, generating a record, and saving the record by chains; S2, after a transaction matching settlement contract in the period is triggered, reading the latest electricity selling record from the blockchain and matching transactions S3, generating a transaction pre-matching record and performing uplink storage; S4, enabling an electricity selling user to acquire the transaction pre-matching record from the blockchain and authorize a transaction pre-matching record, and generating and saving an electric power transaction matching record by chains; and S5, enabling an electricity purchasing user to acquire the transaction pre-matching record and an electricity transaction matching record with the electricity selling user private key signature from the block chain, complete transaction account transfer, generate an account transfer record, and upload and save the account transfer record by chains. According to the matching method based on the multi-objective decision, an accurate utility function calculation method is provided, and a corresponding multi-attribute combination method is designed according to the relationship among the attributes, so that matching satisfaction of a transaction subject can be improved.

Description

technical field [0001] The invention belongs to the field of energy Internet and relates to a P2P energy transaction method based on blockchain and multi-objective decision-making. Background technique [0002] With the continuous deployment of distributed power generation equipment, the traditional centralized power market can no longer meet the balance of energy generation and consumption. The increase in distributed energy resources (Distributed Energy Resources, DER) deployment and the development of P2P energy trading markets are reorganizing the traditional methods of electricity trading on a global scale, enabling private buyers and entities capable of distributed generation to actively participate in the restructured electricity. market. P2P energy trading represents direct energy trading between distributed nodes, and its main purpose is to encourage market participants to trade with each other without the direct influence of a central controller. [0003] The cor...

Problems solved by technology

[0005] However, how to find an equilibrium point acceptable to all parties under the premise of maximizing their own interests is a very challenging issue

And the current game theory model (Cournot game model, Stackelberg game model, etc.) is just a simple price or output game, and does not consider user behavior and preferences

And the use of game theory usually requires modeling, which makes the computational complexity of solving game problems very high

In addition, the existing methods considering multi-attribute matching generally need to establish a mathematical model to solve, and the computational complexity and solution time are very high.

To sum up, the traditional transaction matching method is either a simple bilateral matching that only considers price factors, or the calculation complexity of the solution is very high, so it cannot meet the requirements of the current energy trading market
