Description

Technical Field

[0001] This invention belongs to the field of power system automation technology, specifically relating to a reliable interaction method and system for carbon metering data. Background Technology

[0002] As the "dual carbon" goals continue to advance, the demand for collaborative metering and management of electricity consumption data and carbon emission data in the power system is constantly increasing. Electricity carbon metering data is not only linked to user energy consumption analysis and carbon emission accounting, but also to green electricity trading, environmental attribute management, and data flow and result verification in related business processes. Therefore, building a secure and reliable data interaction mechanism around electricity carbon metering data has become an important technical requirement in the field of power metering.

[0003] In existing technologies, smart meters typically collect, store, and upload electricity data. Some solutions can also combine the electricity carbon factor issued by the main station to generate carbon emission-related data, or enhance data security through encryption and evidence storage. In some application scenarios, metering data will also be uploaded to the main station or other platforms to support subsequent data processing, business verification, or shared use.

[0004] However, existing technologies still have shortcomings in the scenario of trusted interaction of carbon metering data: First, there is a lack of a unified trusted interaction mechanism in the process of carbon metering data flowing to the main station and other business entities after its generation, resulting in insufficient verification capabilities for the reliability of data sources and the consistency after transmission; Second, existing solutions mostly focus on data collection, calculation, or single-point storage protection, lacking a unified identification and association mechanism between carbon metering data and green electricity attribute-related data, leading to unclear data correspondence and difficulty in supporting subsequent verification and traceability; Third, in the process of sharing and using carbon metering data across entities, there is a lack of data verification and evidence storage verification links for multiple parties, which can easily lead to difficulties in trusted verification, unclear responsibility boundaries, and insufficient traceability efficiency.

[0005] Therefore, there is an urgent need for a reliable interaction method for carbon metering data to improve the reliability and traceability of carbon metering data in the process of cross-entity transfer. Summary of the Invention

[0006] This invention provides a reliable interaction method for carbon metering data. The solution constructs a data interaction process that includes dynamic carbon factor reception, electricity kilowatt-hour coding, digital signature, evidence storage processing, and signature verification. It performs green code association, signature upload, and evidence storage verification on the carbon metering data generated by the carbon metering smart meter, and outputs a reliable verification result. This solves the technical problems of difficult reliable verification, lack of unique identifiers, and insufficient traceability of carbon metering data during cross-entity transfer.

[0007] A first aspect of the present invention provides a reliable interaction method for carbon metering data, the method comprising: The system acquires electricity data based on a smart energy meter with carbon metering, receives dynamic carbon factors from the main station, generates carbon metering data based on the electricity data and the dynamic carbon factors, and performs electricity consumption coding based on the carbon metering data to generate a green code.

[0008] By adopting the above scheme, the present invention provides a trusted interaction method for carbon emission metering data. This method generates carbon emission metering data by acquiring electricity consumption data and receiving dynamic carbon emission factors, thus establishing a correlation between electricity consumption information and carbon emission information.

Furthermore, it performs digital signatures on the carbon emission metering data and the green code based on the public-private key pair built into the carbon emission meter, generating signature data to bind the source identity of the carbon emission metering data and the green code.

This significantly improves the verifiability and traceability of the carbon emission metering data during the interaction process. Simultaneously, by performing signature verification on the signature data based on the public key, and verifying the carbon metering data and the green code based on the evidence storage record, a trusted verification result is output, achieving joint verification of the authenticity and consistency of the carbon metering data.

[0030] The following detailed description is exemplary and intended to provide further detailed explanation of the invention. Unless otherwise specified, all technical terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention.

[0031] Figure 1 This is a flowchart illustrating a reliable interaction method for carbon metering data provided in an embodiment of the present invention.

[0032] This invention provides a reliable interactive method for carbon metering data, applicable to, for example... Figure 3 The diagram illustrates an interactive scenario involving a smart energy meter for carbon metering, a data acquisition master station, a blockchain-based evidence storage platform, and a business verification entity. The smart energy meter for carbon metering is used to acquire electricity consumption data, generate carbon metering data, assign codes to electricity consumption, and perform digital signatures. The data acquisition master station is used to receive uploaded data and perform evidence storage processing. The business verification entity may include at least one of a transaction center and a payment platform, used to verify and validate the relevant data.

[0033] In this embodiment, the carbon-metered smart energy meter pre-installs a public-private key pair generated based on an asymmetric encryption algorithm (e.g., the national cryptographic algorithm SM2), enabling the smart energy meter to possess digital identity and digital signature capabilities. The public-private key pair can be generated and written before the smart energy meter is put into use.

[0034] Example 1, as Figure 1 and Figure 4 As shown, the present invention provides a reliable interaction method for carbon metering data, the method comprising the following steps: S1. Obtain electricity data based on the smart energy meter with carbon metering, receive dynamic carbon factor sent by the main station, generate carbon metering data based on the electricity data and the dynamic carbon factor, and perform electricity metering code assignment based on the carbon metering data to generate a green code. S2. Based on the public-private key pair built into the smart energy meter for carbon metering, perform digital signature on the carbon metering data and the green code to generate signature data; S3. Upload the carbon metering data, the green code, the signature data, and the public key in the public-private key pair to the data collection master station; the data collection master station performs evidence storage processing on the carbon metering data, the green code, and the signature data to generate evidence storage records; S4. Verify the signature data based on the public key, verify the carbon metering data and the green code based on the evidence storage record, and output a reliable verification result.

[0035] By adopting the above scheme, the present invention provides a trusted interaction method for carbon emission metering data. This method generates carbon emission metering data by acquiring electricity consumption data and receiving dynamic carbon emission factors, thus establishing a correlation between electricity consumption information and carbon emission information. It generates a green code based on the carbon emission metering data, identifying the corresponding electricity consumption. Furthermore, it performs digital signatures on the carbon emission metering data and the green code based on the public-private key pair built into the carbon emission meter, generating signature data to bind the source identity of the carbon emission metering data and the green code. Further, by uploading the carbon emission metering data, the green code, the signature data, and the public key to the data acquisition master station, and having the master station perform evidence storage processing to generate an evidence storage record, it achieves evidence storage and traceability during the carbon emission metering data interaction process. This significantly improves the verifiability and traceability of the carbon emission metering data during the interaction process. Simultaneously, by performing signature verification on the signature data based on the public key, and verifying the carbon metering data and the green code based on the evidence storage record, a trusted verification result is output, achieving joint verification of the authenticity and consistency of the carbon metering data. By linking the electricity metering code assignment, digital signature, evidence storage processing, and signature verification, continuous processing from the generation of carbon metering data to trusted verification is achieved, significantly improving the reliability of trusted interaction of carbon metering data. The technical solution of this invention realizes trusted interaction of carbon metering data, improving the verifiability and traceability of carbon metering data.

[0036] In some embodiments of the present invention, the electrical energy data includes combined active energy, forward active energy, and reverse active energy; The carbon emission data includes both positive and negative carbon emissions. The smart energy meter actively reports the electricity consumption data and the carbon metering data, and / or the data acquisition master station reads the electricity consumption data and the carbon metering data.

[0037] In this embodiment, the electricity data includes combined active energy, forward active energy, and reverse active energy; the carbon emission data includes forward carbon emissions and reverse carbon emissions. The smart energy meter can upload the electricity data and carbon emission data through active reporting, or the data acquisition master station can read the electricity data and carbon emission data.

[0038] Specifically, after the master station sends dynamic carbon factors to the smart energy meter, the smart energy meter retrieves the collected electricity data and combines it with the received dynamic carbon factors to form corresponding carbon metering data. Since the electricity data includes both forward and reverse energy information, and SM2 signatures and digital identities are added during the smart energy meter's active reporting / master station reading process, the carbon metering data can also generate corresponding forward and reverse carbon emission amounts, thus adapting to the data metering requirements in bidirectional energy flow scenarios.

[0039] This embodiment generates carbon emission measurement data by acquiring electricity data and receiving dynamic carbon emission factors, thereby realizing the correlation between electricity information and carbon emission information.

[0040] In some embodiments of the present invention, the step of performing electricity consumption coding based on the electricity carbon metering data to generate a green code includes: Based on a preset time interval, the electricity consumption corresponding to the carbon metering data is assigned a green code by the electricity metering data. And / or, Based on a preset energy threshold, the energy corresponding to the carbon metering data is assigned an energy code, generating a corresponding green code.

[0041] In this embodiment, the electricity kilowatt-hour coding refers to the process of encoding and identifying the electricity amount corresponding to the electricity carbon metering data. The green code is a unique identifier formed after electricity kilowatt-hour coding, used to represent the associated information of the corresponding electricity segment.

[0042] Specifically, this involves assigning a unique and specific code (referred to as a green code) to renewable energy generation and grid-connected electricity based on a certain time period or a certain amount of electricity. (Note: The threshold for fixed-quota coding is generally 1000 kWh, and the time interval for timed coding is generally 1 hour, both of which can be set; when both the time interval for timed coding and the threshold for fixed-quota coding are set to "0", the electricity coding function is not enabled; when either the time interval for timed coding or the threshold for fixed-quota coding is set to "0", the corresponding electricity coding method is not enabled; when neither the time interval for timed coding nor the threshold for fixed-quota coding is set to "0", only the fixed-quota electricity coding function is enabled, and the timed electricity coding function is disabled.) The requirements for the kilowatt-hour coding function of smart energy meters with carbon metering are as follows: It supports two coding methods: fixed-quota coding and timed coding. It records the total number of green codes, the time of occurrence and end of the last 500 occurrences, and the corresponding green code energy, meter asset management code, customer number, generation type, user comprehensive multiplier, user geographical location, and digital signature. The digital signature is derived from the green code energy, meter asset management code, customer number, generation type, user comprehensive multiplier, and user geographical location information using the corresponding encryption algorithm.

[0043] The function of electricity meter coding is as follows: smart energy meters for electricity carbon metering should be able to protect the authenticity and integrity of the generation, storage and transmission of quota coding and timed coding data and events, and prevent the electricity meter coding data from being tampered with or forged.

[0044] Please refer to the following table for the definition of green code energy data objects and the definition of electricity code assignment events:

[0045] In this embodiment, the electricity consumption coding supports two methods: timed coding and quota coding. When using timed coding, the target electricity consumption segments can be divided according to a preset time interval, and a corresponding green code can be generated for each target electricity consumption segment. When using quota coding, the target electricity consumption segments can be divided according to a preset electricity consumption threshold, and a corresponding green code can be generated for the target electricity consumption segments that reach the preset electricity consumption threshold. Through these methods, the electricity consumption corresponding to the electricity consumption data can be segmented and identified according to different application scenarios.

[0046] This embodiment generates a green code by performing electricity-based coding on the electricity carbon metering data, thereby achieving a unique identifier for the electricity volume corresponding to the electricity carbon metering data.

[0047] This implementation generates a corresponding green code by performing electricity-based coding at preset time intervals, thus periodically identifying the electricity consumption corresponding to the carbon metering data within a continuous time period. It also generates a corresponding green code by performing electricity-based coding based on a preset electricity consumption threshold, thus identifying data segments that have reached a predetermined electricity consumption threshold. Furthermore, both the timed coding method and the fixed-quota coding method can be enabled independently or selected according to configuration conditions. Therefore, corresponding green codes can be generated for electricity consumption segments within a continuous time interval or for electricity consumption segments that have reached a predetermined electricity consumption threshold. By using both timed coding and / or fixed-quota coding methods, the electricity-based coding method can be flexibly configured, improving the adaptability of green code generation to different application scenarios.

[0048] In some embodiments of the present invention, the green code corresponds to green code energy; the step of performing a digital signature on the energy carbon metering data and the green code based on the public-private key pair built into the energy carbon meter to generate signature data includes: Extract the green code's corresponding green code energy, smart energy meter identifier (for carbon metering), customer number, power generation type, user comprehensive multiplier, and user geographical location. Generate the signature data based on the green code's energy, smart energy meter identifier (for carbon metering), customer number, power generation type, user comprehensive multiplier, and user geographical location.

[0049] In this embodiment, the smart energy meter for carbon metering has a pre-built public-private key pair to enable it to have identification and signature capabilities, generating signature data corresponding to the carbon metering data and the green code. The digital signature is performed by the smart energy meter itself.

[0050] In this embodiment, the signature data is associated with the carbon metering data and the green health code, thus creating a signature result with an identity binding relationship at the generation end of the uploaded data. This allows the source of the corresponding data to be traced based on the signature data during subsequent data transfer, verification, and validation processes.

[0051] This embodiment uses the public-private key pair built into the smart energy meter to digitally sign the carbon metering data and the green code, generating signature data to bind the source identity of the carbon metering data and the green code. The asymmetric encryption algorithm SM2 (China's national cryptographic standard) can be used to digitally sign the carbon metering data (carbon metering data = electricity consumption * dynamic carbon factor); however, this invention is not limited to this specific algorithm.

[0052] This implementation extracts the green code's corresponding green code energy, smart energy meter identifier, customer number, power generation type, user comprehensive multiplier, and user geographical location, and generates signature data based on this information to bind the green code to its associated metering information, user information, and attribute information. The signature data is used to protect the green code's related information, improving its ability to represent the source and correspondence of the green code. Furthermore, this implementation enhances the credibility of the source data by generating a signature result at the generation end that is bound to the digital identity of the smart energy meter, based on the green code and the green code.

[0053] Furthermore, the carbon metering data, the green code, the signature data, and the public key from the public-private key pair are uploaded to the main data collection station.

[0054] In this embodiment, the uploaded content may further include a timestamp. That is, the carbon metering data, the green code, the signature data, the timestamp, and the public key can be uploaded to the data collection master station. The timestamp is used to characterize the time information corresponding to the currently uploaded data, so as to distinguish the temporal relationship in the subsequent data interaction process.

[0055] The following processing can also be performed: Record the total number of green health codes; Record the occurrence time, end time, and energy level of the green code; The data and events corresponding to the green code are protected in terms of generation, storage, and transmission.

[0056] In this embodiment, the green code record information may further include the identifier of the smart energy meter for carbon metering, customer number, power generation type, user comprehensive multiplier, user geographical location, and signature data; the number of records corresponding to the green code is a preset number.

[0057] By recording and saving the information corresponding to the green code, a green code event traceability result can be formed for subsequent verification and tracing. By recording the total number of green codes, as well as the occurrence time, end time, and energy of each green code, a traceability of the energy allocation process can be achieved. By implementing generation, storage, and transmission protection for the data and events corresponding to the green codes, continuous protection of the code-related information during the formation, storage, and interaction processes can be achieved, improving the integrity and reliability of green code data and event information.

[0058] This embodiment achieves centralized aggregation of interactive data to the main station by uploading the carbon metering data, the green code, the signature data, and the public key in the public-private key pair to the main station.

[0059] This implementation further records the smart energy meter identifier, customer number, power generation type, user comprehensive multiplier, user geographical location, and signature data in the green code record information to achieve extended association of green code record content; by limiting the number of records to a preset number, it achieves continuous preservation of historical green code information, improving the traceability and orderly management of green code record information.

[0060] This implementation method supplements the time sequence identifier of the uploaded data by uploading the timestamp along with the carbon metering data, green code, signature data, and public key to the main collection station. By introducing time information into the uploaded content, it improves the ability to distinguish the time relationship of the carbon metering data interaction and provides a basis for verification.

[0061] In some embodiments of the present invention, the step of the main data acquisition station performing evidence storage processing on the carbon metering data, the green code, and the signature data to generate evidence storage records includes: The main data collection station uploads the carbon metering data, the green code, and the signature data to the blockchain to generate the evidence storage record.

[0062] Specifically, after receiving the carbon metering data, green code, signature data, and public key, the main station submits the carbon metering data, green code, and signature data to the blockchain for evidence storage processing, creating an evidence storage record on the chain corresponding to the carbon metering data and green code. Through this method, a traceable record of the interactive data can be created on the main station side.

[0063] By performing evidence storage processing at the main data acquisition station, evidence storage records are generated, thus achieving evidence storage and traceability during the interaction of electricity carbon metering data.

[0064] This implementation method uploads the carbon metering data, green code, and signature data to the blockchain by the main data collection station to generate a storage record, thereby achieving on-chain storage of relevant interactive data. By specifically implementing the storage process on the blockchain, it achieves distributed traceability of carbon metering data and green code information, improving the credibility and traceability of the storage record.

[0065] In some embodiments of the present invention, the step of performing signature verification on the signature data based on the public key, verifying the carbon metering data and the green code based on the evidence storage record, and outputting a trusted verification result includes: At least one of the transaction center and the payment platform performs signature verification on the signature data based on the public key, verifies the carbon metering data and the green code based on the evidence storage record, and outputs the trusted verification result.

[0066] Specifically, in business verification scenarios, the transaction center and / or payment platform can retrieve the public key to verify the signature data and determine whether the current signature data matches the uploaded data. Simultaneously, they can retrieve the stored records to verify the carbon metering data and green health code to determine their consistency with the stored data. If both signature verification and validation pass, a trusted verification result is output; if either verification or validation fails, an untrusted verification result is output to prompt further processing.

[0067] By performing signature verification based on the public key and performing verification based on the stored evidence record, joint verification of the authenticity and consistency of the carbon metering data can be achieved.

[0068] This implementation achieves trusted verification for business users by having at least one of the transaction center and payment platform perform signature verification on the signature data based on a public key, and verify the carbon metering data and green code based on the evidence storage record. By extending the signature verification subject to the transaction center and payment platform, it improves the independent verification capability and application support capability of carbon metering data in multi-subject interaction scenarios.

[0069] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention generates electricity carbon metering data by acquiring electricity data and receiving dynamic electricity carbon factors; it generates green codes by performing electricity-based coding based on the electricity carbon metering data, thereby realizing the correlation processing of electricity information, carbon emission information and green code identification information; furthermore, by recording the total number of green codes, the time of occurrence, the time of end, the electricity energy of the green code and related information, it realizes the continuous tracking of the electricity coding results, thereby improving the corresponding management capability between electricity carbon metering data and green electricity attribute information.

[0070] This invention utilizes the public-private key pair built into the smart energy meter to digitally sign carbon metering data and the green code, generating signature data to achieve data source identity binding. By uploading the carbon metering data, green code, signature data, and public key to the data acquisition master station, which then performs evidence storage processing to generate an evidence storage record, this invention achieves evidence storage and traceability during the carbon metering data interaction process. Furthermore, by implementing generation, storage, and transmission protection for the data and events corresponding to the green code, continuous protection of the code-related information is achieved, thereby improving the integrity and traceability of the carbon metering data during the interaction process.

[0071] This invention achieves joint verification of the authenticity and consistency of relevant data by performing signature verification on the signed data based on public keys and verifying the electricity carbon metering data and green code based on the stored records, and outputting a trusted verification result. Furthermore, by having at least one party, either the trading center or the payment platform, participate in the signature verification and validation, it achieves trusted verification for multi-entity business scenarios. Moreover, by connecting the generation of electricity carbon metering data, the assignment of electricity-per-hour codes, digital signatures, stored records, and signature verification, it achieves continuous processing from data formation to trusted verification, thereby improving the trusted interaction capability of electricity carbon metering data in green electricity trading, carbon emission accounting, and related business applications.

The evidence storage and verification module is used by the main collection station to perform evidence storage processing on the carbon metering data, the green code, and the signature data to generate evidence storage records; to perform signature verification on the signature data based on the public key; to perform verification on the carbon metering data and the green code based on the evidence storage records; and to output a reliable verification result.
