Description
Technical Field
The invention relates to the technical field of new energy electric power traceability, in particular to a new energy electric power traceability method and system based on a block chain.
Background
The block chain is a chain data structure formed by combining data blocks in a sequential connection mode according to a time sequence, and is a distributed account book which is guaranteed in a cryptographic mode and cannot be tampered and forged. Broadly speaking, the blockchain technique is a completely new distributed infrastructure and computing paradigm that utilizes blockchain data structures to verify and store data, utilizes distributed node consensus algorithms to generate and update data, cryptographically secure data transmission and access, and utilizes intelligent contracts composed of automated script code to program and manipulate data. Data stored in the block chain needs to be maintained by nodes of the whole network together, and value can be effectively transferred between nodes which lack trust. Compared with the existing database technology, the block chain has the characteristics of multiple centers, automation and trustiness.
An intelligent contract is a contract that records terms in a computer language instead of a legal language. 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 the blockchain technology to be applied in reality. Contracts in the traditional sense are generally not directly linked to computer code that executes the contract's content. Paper contracts are in most cases archived, while software implements contract terms written in computer code. Potential benefits of intelligent contracts include reduced cost in contracting, executing, and supervising; thus, for many contracts related to low value transactions, this is a significant reduction in labor costs.
In the field of electric power, a physical source tracing mode for electric power exists, such as calculation and statistics of electric power flow, but the source tracing difficulty in the form is high, and the effect is not ideal, so that the electric power industry matches electric power more economically. Therefore, for this scenario, a power traceability system based on a block chain is needed to provide system function guarantee for each link of power traceability.

In the new energy source tracing method 100 based on the block chain provided by the embodiment of the invention, starting from step 101, an electricity purchase transaction contract and at least one new energy source scheduling plan curve are obtained in step 101, and the electricity purchase transaction contract and the new energy source scheduling plan curve are stored in the block chain.
In step 102, capturing key field information in the electricity purchasing trade 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, wherein the key field information includes: a transaction number, a power generation area name, a power receiving area name, and a power type; the data format of the key field information format data is transaction number + power generation area name + power receiving area name + power type.
The green electricity tracing means that physical electricity is digitally mapped onto a block chain through various links of opening transaction and scheduling to become a digital traceable commodity, and the purpose of accurately tracing the renewable energy electricity is achieved. As shown in fig. 2 and 3, in the embodiment of the present invention, the related roles include a beijing electricity trading center, a national dispatching center, and an order center of a car networking platform, and each main body provides its own data field to combine to generate a unique green power certificate, so as to trace the source of the new energy electricity used by the new energy vehicle.
The power trading center uploads a power purchasing trading contract to the block chain, and the dispatching center uploads a dispatching plan curve of the new energy power to the block chain. Then, capturing key field information in the contract through the intelligent contract, wherein the key field information comprises transaction notice number, power generation province information, power receiving province information and transaction power type information, converting the captured information into marks in corresponding formats to be combined in order, and forming part of evidence passing. In the figure, the transaction number is 10001, the power generation province is Qinghai, the power receiving province is Beijing, and the power type is 02 for representing wind power (the representing number of each new energy power is preset), and the data in the key field information format can be determined as follows according to the data format of the data in the key field information format: 10001QHBJ02 (i.e. passport fragment 1).
In step 103, determining a corresponding new energy scheduling plan curve according to the key field information, and hashing the determined corresponding new energy scheduling plan curve to obtain scheduling curve hash data.
In the embodiment of the invention, the corresponding scheduling plan curve is determined according to the information of the power generation province, the power receiving province and the power type extracted from the power purchase transaction contract, the determined scheduling curve is hashed, and the obtained hash data is added to the key field information format data through the intelligent contract to form the first half content of the general evidence. As shown in fig. 2 and 3, the key field information format data is: 10001QHBJ02 (i.e., certification-enabled fragment 1), generating the scheduling curve hash data to be 0X … C7 (i.e., certification-enabled fragment 2, 0X is used to indicate that the obtained scheduling curve hash data is hexadecimal), the first half of the green trace-source certificate generated by performing field matching by the smart contract is: 10001QHBJ020X … C7.
In addition, at this time, the first half of the certificate may not be generated, but the green electronic certificate may be directly determined after the key field information format data, the scheduling curve hash data and the order information format data are all acquired.
In an embodiment of the present invention, the schedule plan curve may be a daily schedule plan curve. When a scheduling center determines a day scheduling plan curve, if a numerical value is taken every 15 minutes, the curve is converted into a 16-system character string corresponding to a string of indefinite length numerical value strings containing 96 point numerical values, the character string is set to be m, the character string is subjected to Hash transformation through an SHA256 secure hash function algorithm, and Hash (m) of indefinite length is obtained after grouping, filling and encryption. The basic computing idea of the SHA256 secure hash function algorithm is as follows: dividing the message m into N512-bit data blocks, enabling a hash initial value H (0) to pass through a first data block to obtain H (1), enabling H (1) to pass through a second data block to obtain H (2), and processing the H (2) and the H (1) sequentially to obtain H (N), then connecting 8 32 bits of H (N) into a 256-bit message digest and representing the message digest according to a 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 in a block chain, 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 comprises: 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 implementation mode of the invention, after the front end generates the new energy electricity consumption order of the charging pile user, the order center immediately uploads the order to the block chain, analyzes the order number and the current charging amount information of the user according to the new energy electricity consumption order, converts the order number and the current charging amount information into the identification with the corresponding format for orderly combination, and acquires the order information format data. As shown in fig. 2 and fig. 3, the intelligent contract captures the order number and the electricity consumption field, and generates order information format data as follows: x … XX00100 (i.e. Certification piece 3).
In the implementation mode of the invention, the bit number of the key field information format data, the scheduling curve hash data and the order information format data is set according to the actual requirement.
In step 105, the key field information format data, the scheduling curve hash data and the order information format data are associated through an intelligent contract to obtain a green electric certificate, the green electric certificate is stored on a block chain, and the green electric certificate including the green electric source tracing identification code 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 through the intelligent contract to obtain the green electronic certificate, and storing the green electronic certificate on the blockchain, includes:
and carrying out field matching through an intelligent contract, orderly combining the key field information format data, the scheduling curve hash data and the order information format data according to the sequence of arranging the key field information format data, the scheduling curve hash data and the order information format data in sequence to obtain the green electric certificate, and storing the green electric certificate on a block chain.
Preferably, wherein the method further comprises:
carrying out format and integrity verification on the green electronic certificate; if the verification passes, storing the green electronic certificate on a block chain; and if the verification fails, feeding back error information and regenerating the green electronic certificate until the verification passes and then storing the green electronic certificate on the block chain.
In the implementation mode of the invention, the key field information format data, the scheduling curve hash data and the order information format data are associated through an intelligent contract, and the key field information format data, the scheduling curve hash data and the order information format data are orderly combined according to the sequence of arranging the key field information format data, the scheduling curve hash data and the order information format data in sequence, so that the completed green electronic certificate is ensured. As shown in fig. 2 and 3, the generated green certificate is: 00001SXBJ020X … C7X … XX 00100.
