Medium and long term electricity transaction method and system based on smart contract

Abstract

The invention discloses a medium and long term power transaction method and system based on a smart contract, and belongs to the field of distributed power transaction, and the method comprises the steps: S1, a power grid enterprise sets a power transmission and distribution price, and uploads the power transmission and distribution price to a block chain; S2, after the electricity seller and the electricity purchaser reach a transaction intention, an intelligent contract is called to obtain the power transmission and distribution price from the block chain to draw up a medium and long term transaction contract and the transaction contract is stored to the block chain through the smart contract; S3, the power grid enterprise calls an intelligent contract to obtain a transaction contract from the block chain and performs security check and when the security check result is that the transaction is approved, contract signing succeeds; S4, the power grid enterprise uploads the measured transaction electric quantity of the seller and the buyer to the block chain through the smart contract for electric quantity settlement; and S5, the electricity purchaser sends the settled transaction fee to the smart contract account so that the smart contract account can distribute the transaction fee, and contract execution is completed. According to the invention, the problems of low cross-department data processing efficiency and difficulty in transaction information tracing and supervision in medium and long-term power transactions can be solved.

Description

technical field [0001] The invention belongs to the field of distributed power trading, and more specifically relates to a method and system for mid- and long-term power trading based on smart contracts. Background technique [0002] Medium and long-term electricity transactions refer to electricity wholesale transactions carried out between market entities such as power generation companies, power users, and electricity sales companies, with transaction cycles of multiple years, years, seasons, months, weeks, and multiple days. According to the current medium and long-term trading rules of electric power, trading institutions need to submit market pre-sale results to power grid companies for security verification, and this process involves data transmission between departments. Since each department in the market operates independently and stores and maintains the collected data separately, data islands are formed between departments. Cross-departmental data analysis has hi...

Problems solved by technology

[0006] In view of the above defects or improvement needs of the prior art, the present invention provides a medium and long-term power trading method and system based on smart contracts, the purpose of which is to use blockchain and smart contracts to realize medium and long-term transactions involving the participation of power grid enterprises in large power grids With the help of blockchain storage data, it cannot be tampered with and can be traced. Smart contracts do not require trust from authoritative parties and are automatically executed to solve the technical problems of low efficiency of cross-departmental data analysis and difficult transaction information traceability and supervision in the current medium and long-term power trading market.
