[0002] As the technology of distributed power generation such as solar energy and wind energy becomes increasingly mature, many electricity consumers use solar photovoltaic panels, wind power and natural gas generators to generate electricity. Therefore, distributed power energy transactions represented by "new energy + Internet" are developing rapidly. At present, the roles of producers and consumers in distributed power energy transactions tend to be diversified and miniaturized. Sometimes the producers of power energy are also consumers. At the same time, distributed power transactions are usually conducted directly by power energy producers and consumers at an unfixed selling price. The traditional transaction method centered on power grid companies can no longer meet the needs of distributed power transactions. Due to the flexibility and diversity of distributed power transaction types, the reliability of the transaction process cannot be guaranteed.

[0003] With the accelerated development of the energy internet, many problems have gradually been exposed. The trust barriers between energy industries have not yet been broken, and it is difficult to achieve effective coordination and interaction between multiple links such as sources, networks, loads, and storage.

[0021] Step S12: signing the power transaction request information, and generating power transaction broadcast information according to the block header information and the signed power transaction request information; Step S13: Publish the electricity transaction broadcast information to the blockchain.

[0022] Step S2: Match the power transaction request according to the set power transaction matching rules, generate power transaction matching information, publish it to the blockchain transaction platform and broadcast it.

[0023] The step S2 specifically includes the following steps: Step S21: Obtaining the agreed electricity price for power trading and the electricity price for power trading; Step S22: Calculate the power transaction price difference according to the power transaction agreed price and the power transaction transaction price; Step S23: setting a power transaction matching rule according to the power transaction price difference, and matching power transaction requests within a set period according to the set power transaction matching rule; Step S24: If the match is successful, the power transaction matching information is generated and published to the blockchain transaction platform and broadcast; if the match fails, the power transaction request is modified and the matching continues. If the match is not successful within the set period, the matching fails.

[0024] Step S3: Distributed authentication matches successfully the electricity transaction and executes the authenticated electricity transaction.

[0025] Step S4: Execute power transaction settlement according to the power transaction smart contract obtained from the blockchain transaction platform.

[0026] Furthermore, the specific operations of step S3 are: Step S31: Matching the power transaction broadcast information with the acquired power sales information; Step S32: According to the set consensus mechanism, the distributed authentication successfully matches the power transaction broadcast information corresponding to the power transaction request.

[0027] Furthermore, the step S4 specifically includes the following steps: Step S41: executing power trading on the distributed authenticated power trading request according to the power trading matching result; Step S42: Settle the power transaction according to the power transaction smart contract obtained from the blockchain transaction platform.

[0028] Furthermore, the specific operation of step S42 is: first, lock the account balances of both parties to the transaction according to the smart contract obtained from the blockchain transaction platform, then encrypt the payment voucher according to the private key signature of the transaction payee and the public key of the transaction payee, and decrypt the payment voucher according to the private key of the transaction payee, and finally complete the electricity transaction settlement according to the decrypted payment voucher.

[0029] Working principle: This embodiment first generates power transaction broadcast information according to the power transaction request, publishes it to the blockchain and broadcasts it; secondly, it matches the power transaction request according to the set power transaction matching rules, generates power transaction matching information, publishes it to the blockchain transaction platform and broadcasts it; then, distributed authentication matches the successfully matched power transaction, and executes the authenticated power transaction; finally, according to the power transaction smart contract obtained from the blockchain transaction platform, executes the power transaction settlement; realizes the blockchain-based power user-side management, reduces the hierarchical level and intermediate links of the transaction system, and directly realizes point-to-point power transactions.

[0030] Embodiment 2: This embodiment is based on the above embodiment 1. Figure 1 As shown, a specific embodiment is described in detail, which specifically includes the following steps.

[0031] Step S1: The two parties to the power transaction issue a power transaction request based on demand, sign the transaction request and publish it to the blockchain, and broadcast it. The broadcasted transaction request information includes the user identification, i.e., user ID, transaction volume, transaction price, and transaction time. The generated power transaction broadcast information includes the block header information, i.e., block version number, timestamp and random number, as well as the signed transaction request information.

[0032] Step S2: According to the set transaction matching rules, the power transaction requests obtained in the blockchain power trading platform within a certain period of time are matched, and the power transaction smart contract is combined to promote power transaction matching; the successfully matched power transactions are broadcast to the blockchain trading platform, the transaction requests of the failed power transactions are modified, and the modified power transaction requests are matched again until the match is successful. If the match is not successful at the end of the set transaction matching time, the transaction matching in this cycle fails.

[0033] The specific power transaction matching rules include: G min =G i,a -G j,b Among them, G min is the price difference of electricity trading, G min ≥0, G i,a The electricity price is agreed upon for power trading, G j,b is the electricity price of electricity trading, i and j are blockchain nodes.

[0034] Step S3: The successfully matched power transactions are distributedly authenticated. The broadcast matching information needs to undergo consensus voting and signature authentication. During the distributed authentication, the power transaction request and power sales information are matched, and the successfully matched information is further distributedly authenticated according to the set consensus constraints.

[0035] The consensus constraint set in this embodiment is that the authentication is successful if more than 50% of the blockchain nodes agree to the power transaction.

[0036] Step S4: The power transaction smart contract obtained from the blockchain transaction platform will execute the power transaction according to the power transaction matching result of the successfully authenticated power transaction request, and conduct the power transaction settlement. During the power transaction settlement process, the account balances of both parties to the power transaction are locked according to the power transaction smart contract. The power transaction payer signs with its own private key and encrypts it with the public key of the power transaction payee, and sends it to the power transaction payee. The power transaction payee uses its own private key to decrypt the payer's certificate, completes the transaction settlement, and unlocks the accounts of both parties to the transaction.

[0037] Working principle: This embodiment realizes distributed power trading based on blockchain, and uses blockchain as the technical support point of the power trading platform to carry out power energy trading in the micro-energy network, effectively breaking the traditional power trading barriers; and according to the formulated power trading matching rules, a new distributed power trading model is constructed to realize blockchain-based power user-side management, reduce the hierarchical levels and intermediate links of the trading system, and directly realize point-to-point power trading.
