Description
Technical Field
The invention relates to the technical field of new energy power tracing, in particular to a new energy power tracing method and system based on a block chain.
Background
Blockchains are a kind of chained data structures that combine blocks of data in a sequential manner in time order, and cryptographically guaranteed, non-tamperable and non-counterfeitable distributed ledgers. In broad terms, blockchain technology is a completely new distributed infrastructure and computing paradigm that utilizes blockchain data structures to validate and store data, distributed node consensus algorithms to generate and update data, cryptography to secure data transfer and access, and intelligent contracts composed of automated script code to program and manipulate data. The data stored on the blockchain needs to be commonly maintained by the nodes of the whole network, so that the value can be effectively transferred between the nodes which lack trust. Compared with the existing database technology, the blockchain has the characteristics of multi-center, automation and trust.
An intelligent contract is a contract that replaces legal language with computer language to record terms. The smart contract may be automatically executed by a computing system. If the blockchain is a database, the intelligent contract is an application layer that enables blockchain technology to be applied to reality. Traditionally, contracts have not generally been directly tied to the computer code executing the contents of the contract. Paper contracts are in most cases archived, and software will execute the contract terms written in computer code. Potential benefits of smart contracts include reduced costs in contracting, executing, and supervising; thus, this is a significant reduction in labor costs for many low value transaction related contracts.
In the power field, there is a physical tracing mode for power, such as calculating and counting power flow, but the tracing difficulty of that form is large and the effect is not ideal, so the power industry is more to match power through economy. Therefore, for this scenario, a power tracing system based on a blockchain is needed to provide a system function guarantee for each link of power tracing.

Fig. 1 is a flowchart of a new energy power tracing method 100 based on a blockchain according to an embodiment of the invention. As shown in fig. 1, in the new energy power tracing method based on the blockchain provided by the embodiment of the invention, a power purchase transaction contract, a new energy scheduling plan curve and a new energy point consumption order are stored in the blockchain and analyzed, key field information format data, scheduling curve hash data and order information format data are acquired and correlated, so that a green electricity certificate with a unique identifier is stored in the blockchain, and the green electricity is traced by a method of tracing digital identifiers; the invention is based on the distributed account book, the data privacy security, the data precision right and other mechanisms of the blockchain, opens up the information barriers of the transaction center, the dispatching and the electricity utilization side, promotes the data sharing and the cooperation, and realizes the data mutual trust and the secure transmission among all the mechanisms through the core technologies of an asymmetric encryption algorithm, a consensus mechanism and the like; the work efficiency is improved through the distributed data account book, the storage safety and the transmission reliability of data are guaranteed through the non-falsifiability of the blockchain, and the generation and the distribution of large-scale green evidence at a user side are effectively supported through a high-availability blockchain bottom layer platform; ensuring the transparency of the service execution process through intelligent contracts; the invention can realize the standardized and normalized management of clean energy consumption statistics, and can effectively integrate the electric power market resources and reduce the actual requirements of power generation cost. The new energy power tracing method 100 based on the blockchain provided by the embodiment of the invention starts from step 101, acquires a power purchase transaction contract and at least one new energy scheduling plan curve in step 101, and stores the power purchase transaction contract and the new energy scheduling plan curve in the blockchain.
In step 102, capturing key field information in the electricity purchase transaction contract through an intelligent contract, and determining key field information format data according to a preset first data format based on the key field information.
Preferably, the key field information includes: transaction number, power generation area name, power receiving area name, and power type; the data format of the key field information format data is transaction number, power generation area name, power receiving area name and power type.
The green electricity tracing is to map the physical electricity digitally onto the blockchain by opening up all links of transaction and scheduling, so that the digital traceable commodity is changed, and the purpose of precisely tracing renewable energy electricity is achieved. As shown in fig. 2 and fig. 3, in the embodiment of the present invention, the roles involved include a beijing electric power transaction center, a national dispatching center and a platform order center of the internet of vehicles, and each main body respectively provides own data fields to combine to generate a unique green electricity passing certificate, so as to implement tracing of new energy electricity usage for new energy vehicles.
The power transaction center uploads the power purchase transaction contract to the blockchain, and the scheduling center uploads the scheduling plan curve of the new energy power to the blockchain. Then, key field information in the contract is captured through the intelligent contract, wherein the key field information comprises transaction bulletin numbers, power generation provinces, power receiving provinces and power type information of transactions, the captured information is converted into corresponding format identifiers to be orderly combined, and partial pass is formed. In the figure, the transaction number is 10001, the power generation province is Qinghai, the power receiving province is Beijing, the power type is 02 and represents wind power (the representative number of each new energy power is preset), and the key field information format data can be determined according to the data format of the key field information format data: 10001QHBJ02 (i.e., universal fragment 1).
In step 103, a corresponding new energy scheduling plan curve is determined according to the key field information, and the determined corresponding new energy scheduling plan curve is hashed to obtain scheduling curve hash data.
In the embodiment of the invention, the corresponding scheduling curve is determined according to the power generation province, the power receiving province and the power type information extracted from the power purchase transaction contract, the determined scheduling curve is hashed, and the acquired hash data is added to the key field information format data through the intelligent contract to form the first half part of the content of the pass. As shown in fig. 2 and 3, the key field information format data is: 10001QHBJ02 (i.e., pass-through fragment 1) generates a scheduling curve hash of 0X … C7 (i.e., pass-through fragment 2,0X is used to represent that the acquired scheduling curve hash data is hexadecimal), then the first half of generating a green electricity tracing credential by performing field matching through an intelligent contract is: 10001QHBJ020X … C7.
In this case, the green license may be directly determined after the key field information format data, the scheduling curve hash data, and the order information format data are acquired, instead of generating the first half of the license.
In an embodiment of the present invention, the schedule plan curve may be a daily schedule plan curve. When a dispatching center determines a day dispatching plan curve, if a numerical value is taken every 15 minutes, the curve corresponds to a string of indefinite length numerical value strings containing 96 point numerical values, the string is converted into a 16-system character string, the character string is set as m, hash transformation is carried out on the character string through an SHA256 secure Hash function algorithm, and Hash data Hash (m) with a fixed length of 256b is obtained after grouping, filling and encryption processing. The basic calculation thought of the SHA256 secure hash function algorithm is as follows: dividing the message m into N512-bit data blocks, obtaining H (1) by the hash initial value H (0) through a first data block, obtaining H (2) by the H (1) through a second data block, sequentially processing, finally obtaining H (N), connecting 8 32 bits of the H (N) into a 256-bit message abstract, and representing according to hexadecimal format to obtain the obtained hash data.
In step 104, a new energy electricity consumption order matched with the electricity purchase transaction contract is acquired and stored on a blockchain, the new energy electricity consumption order is analyzed, order information is acquired, and order information format data is determined according to a preset second data format based on the order information.
Preferably, wherein the order information includes: order number and current charge amount information; the data format of the order information format data is "order number+present charge amount information".
In the embodiment of the invention, after a new energy electricity consumption order of a charging pile user is generated at the front end, an order center immediately uploads the order to a blockchain, and according to the new energy electricity consumption order, the order number and the current charge amount information of the user are analyzed, and the order number and the current charge amount information are converted into corresponding format identifiers for ordered combination, so that order information format data are obtained. As shown in fig. 2 and 3, the smart contract captures the order number and the electricity consumption field, and generates order information format data as follows: x … XX00100 (i.e. pass-through fragment 3).
In the embodiment of the invention, the bit numbers of the key field information format data, the scheduling curve hash data and the order information format data are set according to actual requirements.
In step 105, the key field information format data, the scheduling curve hash data and the order information format data are associated through the intelligent contract, so as to obtain a green evidence, and the green evidence is stored on the blockchain, and a green traceability certificate including the green evidence is fed back to the user side.
Preferably, the associating the key field information format data, the scheduling curve hash data and the order information format data by the smart contract to obtain a green license for storage on a blockchain includes:
and carrying out field matching through the intelligent contract, orderly combining the key field information format data, the dispatching curve hash data and the order information format data according to the sequence of arranging the key field information format data, the dispatching curve hash data and the order information format data in sequence so as to obtain a green electricity passing certificate, and storing the green electricity passing certificate on a block chain.
Preferably, wherein the method further comprises:
performing format and integrity verification on the green evidence; if the verification is passed, the green electricity passing certificate is stored on a block chain; if the verification is not passed, the error information is fed back, and the green electricity through certificate is regenerated until the verification is passed, and the green electricity through certificate is stored on the blockchain.
In an embodiment of the present invention, the key field information format data, the scheduling curve hash data and the order information format data are associated by an intelligent contract, and the key field information format data, the scheduling curve hash data and the order information format data are sequentially combined in the order of sequentially arranging the key field information format data, the scheduling curve hash data and the order information format data, thereby determining the completed green license. As shown in fig. 2 and 3, the generated green electricity is verified as: 00001SXBJ020X … C7X … XX00100.
In addition, the smart contract specifies the order of field combinations and verifies the certification format, including: performing format and integrity verification on the green evidence; if the verification is passed, the green electricity passing certificate is stored on a block chain; if the verification is not passed, the error information is fed back, and the green electricity through certificate is regenerated until the verification is passed, and the green electricity through certificate is stored on the blockchain.
Finally, the green power tracing certificate shown in fig. 4 is determined according to the green power certificate and fed back to the user side. The complete green electricity tracing certificate is fed back to the Internet of vehicles service system, and after the charging is completed, the user can receive the corresponding green electricity tracing certificate on the front-end page, so that the electricity used by the user is proved to be new energy electricity.
