Description

Technical Field

[0001] The present invention belongs to the technical field of power transaction management and control, and specifically relates to a power transaction management and control system and method based on blockchain. Background Art

[0002] Blockchain is essentially a shared database. The data or information stored in it is unforgeable, traceable, traceable, open and transparent, and collectively maintained. The core technologies of blockchain mainly include: Distributed ledger technology: Blockchain uses distributed ledger technology to disperse data to multiple nodes, each of which stores a complete copy of the ledger. This technology ensures the security and immutability of data, because any modification of the data needs to be verified and agreed upon by multiple nodes in the network.

[0003] Asymmetric encryption technology: In blockchain, asymmetric encryption technology is used to protect the confidentiality and integrity of data. Each participant has a pair of public and private keys, the public key is used to encrypt information, and the private key is used to decrypt information. This encryption method ensures that only users holding the corresponding private key can access and decrypt data, greatly improving data security.

[0004] Consensus mechanism: The consensus mechanism is the rules and methods for reaching consensus among nodes in the blockchain network. It ensures that in a decentralized network environment, all nodes can reach consensus on the modification and addition of data. Common consensus mechanisms include proof of work (PoW), proof of stake (PoS), etc.

[0005] Smart Contract: A smart contract is a computer program that automatically executes and verifies the terms of a contract. It is based on blockchain technology and can execute preset rules and conditions without the intervention of a third party. The emergence of smart contracts has greatly improved the efficiency and security of transactions and reduced the possibility of human intervention and fraud.

The buyer selects the seller and sets the pre-purchased power quantity and auction price based on the market trend and the seller's transaction credit ranking, and generates power purchase information and stores it on the blockchain. The power selling information includes the seller's real-name authentication information, the power selling quantity and the selling price range, and the power purchase information includes the buyer's real-name authentication information, the seller's information, the pre-purchased power quantity and the auction price. The selling price range refers to dividing the power selling quantity into several levels of quantity nodes, and setting a corresponding selling price range for each quantity node, where the quantity node can be a specific value or a data interval range.

[0020] Based on the buyer's pre-purchased electricity quantity and the auction price, the selling price range of the corresponding pre-purchased electricity quantity of the seller selected by the buyer is located. If the auction price does not meet the selling price range, the buyer is reminded to re-set the pre-purchased electricity quantity and auction price for the seller; and during the lock-in transaction time period, the latest electricity purchase information is used to analyze and solve the best combination of electricity purchase information.

[0021] Step S3: During the lock-in transaction period, the power purchase information of each seller is collected, and the objective function is to maximize the sum of the product of the pre-purchased power quantity and the auction price and the sum of the buyer's transaction credit; and the constraint function is that the sum of the pre-purchased power quantity is less than the sold power quantity and each auction price is within the selling price range, and the best combination of power purchase information is solved; First, several selling plans can be obtained by maximizing the seller's profit and solving various constraints; then, based on factors such as maximizing the sum of the transaction credits of each seller entity and minimizing the number of seller entities, the best selling plan, that is, the best combination of electricity purchase information, can be screened out.

[0022] Step S4: Generate a seller preset transaction order and a buyer preset transaction order based on the best combination of power purchase information, and store them on the blockchain; Step S5: The seller and the buyer respectively execute the seller's preset transaction order and the buyer's preset transaction order to conduct electricity trading; the seller's preset transaction order includes the seller's transaction time, refund, seller's penalty commitment, locked selling amount, seller's signature and seller's deadline conditions; the buyer's preset transaction order includes the buyer's transaction time, payment, buyer's penalty commitment, locked buying amount, buyer's signature and buyer's deadline conditions.

[0023] Step S6: Based on the historical electricity trading situation and the company's operating conditions, the transaction credit of the buyer and seller is evaluated respectively, and stored on the blockchain, and the seller's transaction credit ranking is updated.

[0024] The indicators evaluated in step S6 include operation behavior indicators and historical transaction indicators, which are respectively multiplied by the corresponding weight indicators and then added to obtain the transaction credit. The operation behavior indicators are obtained based on the artificial intelligence machine learning evaluation system, which collects the operation information of the enterprise and stores it on the blockchain, and classifies, grades and conducts Bayesian deep learning on the operation information in turn; the operation information includes the enterprise's financial statement library, industry library and quarterly operating report library, the financial statement library includes the enterprise's operating income report and profit report, the industry library includes industry market size information and industry favorable policy information, and the quarterly operating report library includes the enterprise's team information, product information, technical information and market information.

[0025] The present invention realizes the reliability and non-tamperability of transaction information based on blockchain, ensures the fairness of transactions, and realizes the bidding mode of the dynamic fluctuation of the quantity and price of power transactions. At the same time, based on the solution of the objective function and the constraint conditions, the best selling plan for a seller is obtained, which effectively promotes the order rate and the good operation of the platform. Secondly, the present invention realizes the credit evaluation of buyers and sellers based on historical transaction conditions and the company's operation conditions, which facilitates the later buyers to select sellers and the sellers to screen the latest selling plans, forming a good feedback mechanism, reducing the risk of transactions, and has good practicality.
