Description

Technical Field

[0001] The present invention relates to the field of electric power technology, and in particular to a green electric power information processing method, system, electronic equipment and storage medium. Background Art

[0002] With the continued rapid growth of distributed new energy installed capacity and the spatial and temporal imbalance of new energy supply and demand, the wind and solar power abandonment rates in some regions remain high, and the pressure to absorb new energy electricity has become increasingly obvious.

[0003] The power market plays a significant role in optimizing resource allocation, improving power supply security, and promoting renewable energy consumption. In particular, the entry of new entities such as virtual power plants into the market has provided more and more new ways for distributed new energy to participate in the power market. However, for distributed new energy power generation entities, the following problems have also arisen:

[0004] There is currently a lack of a credible metering mechanism for the self-generated and self-used electricity of distributed resources, making it difficult to support the issuance of green certificates for this part of electricity, and unable to guarantee the green electricity benefits of distributed resource entities. For adjustable load entities, after aggregating and participating in green power market transactions, green certificates are transferred to aggregators and other entities, but there is currently a lack of a mechanism to allocate green certificates to each load entity.

[0005] Among them, green electricity traceability uses digital technology to lock in the green rights and interests of renewable energy power stations, and through a real-time traceable power station traceability system, ensures the true traceability of green energy and the uniqueness of green rights and interests.

[0006] Among them, the issuance of green certificates refers to the issuance of tradable green certificates for the grid-connected electricity of renewable energy power generation projects such as wind power, solar power generation, biomass power generation, geothermal power generation, ocean power generation, as well as the grid-connected electricity of fully market-oriented conventional hydropower projects newly put into production after January 1, 2023 (inclusive). Summary of the invention

In this way, it can be avoided that the distributed resource entity is unable to obtain a green certificate due to insufficient green electricity. In addition, this solution can improve the efficiency of issuing green certificates. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0029] Embodiment 1

[0030] Figure 1 is a flow chart of a green power information processing method according to an embodiment of the present invention.

[0031] like Figure 1 As shown, the green power information processing method may include:

[0032] S110, in response to the current settlement request to the aggregator, obtaining the green power to be issued of each of the multiple distributed resource entities corresponding to the aggregator;

[0033] S120, for each distributed resource subject, when the green power of the distributed resource subject to be certified exceeds the standard power for exchanging one green certificate, determine the first number of the distributed resource subject's individually owned green certificates and the first remaining power of the distributed resource subject in this settlement based on the green power of the distributed resource subject to be certified and the standard power for exchanging; when the green power of the distributed resource subject to be certified does not exceed the standard power for exchanging, the green power of the distributed resource subject to be certified is the first remaining power of the distributed resource subject in this settlement;

[0034] S130, determining a second number of green certificates of common ownership of the plurality of distributed resource entities based on the first remaining power of each distributed resource entity in this settlement;

[0035] S140, based on the first number of individual green certificates of ownership of each distributed resource subject and the second number of common green certificates of ownership of multiple distributed resource subjects, corresponding green certificates are issued to multiple distributed resource subjects corresponding to the aggregator.

[0036] It can be understood that the method provided by the embodiment of the present invention can be applied to the power trading center. The power trading center can obtain the relevant data from the blockchain to execute the above method. The above method can be executed at a predicted frequency, for example, every 15 minutes, 20 minutes or 30 minutes. In this way, the efficiency of green certificate issuance can be improved.

[0037] For example, the aggregator may be a trading entity that aggregates one or more distributed resource entities with similar geographical locations. These distributed resource entities may be resource entities with less electricity or insufficient electricity to redeem a green certificate, such as distributed power generation entities or small power users.

[0038] It can be understood that, for a distributed power generation entity, the green power to be certified and the first remaining power are power generation, and for a distributed power user, the green power to be certified and the first remaining power are power consumption.

[0039] Understandably, the standard amount of electricity required to redeem a green certificate is 1MWh of electricity.

[0040] According to the above implementation mode, for the scenario where distributed resource entities participate in power trading, green certificates will be issued to multiple distributed resource entities corresponding to the same aggregator. During the issuance process, for the distributed resource entities whose green electricity to be issued exceeds the standard electricity for exchanging one green certificate, a separate green certificate and the corresponding remaining electricity will be determined for them. For the distributed resource entities whose green electricity to be issued does not exceed the standard electricity for exchanging one green certificate, the green electricity to be issued will be used as the remaining electricity. Then, a green certificate of common ownership will be issued for the remaining electricity of each distributed resource entity. In this way, it can be avoided that the distributed resource entities are unable to obtain green certificates due to insufficient green electricity. In addition, this solution can improve the efficiency of green certificate issuance.

[0041] In one embodiment, based on the distributed resource subject's green electricity to be certified and the exchange standard electricity, the first number of the distributed resource subject's individually owned green certificates and the first remaining electricity of the distributed resource subject in this settlement are determined, including: rounding the ratio between the distributed resource subject's green electricity to be certified and the exchange standard electricity to obtain the first number of the distributed resource subject's individually owned green certificates; subtracting the product of the exchange standard electricity and the first number from the distributed resource subject's green electricity to be certified, to obtain the distributed resource subject's first remaining electricity in this settlement.

[0042] Exemplarily, taking a distributed resource entity as an example, a method may be used to calculate the first quantity and the first remaining power.

[0043] Specifically, the power generation of the i-th distributed generation entity is For distributed power generation entities with grid-connected electricity exceeding 1MWh, a separate green certificate is issued to meet the 1MWh electricity requirement, and the remaining electricity is used to issue a common green certificate. The calculation formula is as follows:

[0044]

[0045]

[0046] in, It is represented by the number of individual green certificates issued to the i-th distributed generation entity; It indicates that the remaining power of the i-th distributed power generation entity is less than 1MWh, that is, the first remaining power mentioned above.

[0047] Similarly, for small-scale electricity users with electricity consumption exceeding 1MWh, the above method can also be used to determine the number of their individually owned green certificates and their first remaining electricity in this settlement.

[0048] According to the above implementation, for distributed resource entities with green electricity exceeding 1MWh, the number of their individual green certificates and the remaining electricity used to issue green certificates with common ownership can be determined. In this way, corresponding green certificates can be issued for resources as much as possible.

[0049] In one embodiment, based on the first remaining power of each distributed resource entity in this settlement, the second number of green certificates of common ownership of multiple distributed resource entities is determined, including: summing the first remaining power of each distributed resource entity in this settlement, and rounding the ratio of the summation result to the exchange standard power, to obtain the second number of green certificates of common ownership of multiple distributed resource entities.

[0050] For example, taking the distributed resource subject as the power generation subject, if the power generation of a single distributed power generation subject is less than 1MWh and the total power generation of multiple power generation subjects is greater than or equal to 1MWh, a green certificate is issued for multiple subjects in an aggregated manner. The calculation method is as follows:

[0051]

[0052] in, Indicates the number of joint ownership green certificates.

[0053] Exemplarily, for electricity users, a similar formula as above can also be used. For the situation where the electricity consumption of a single small electricity user is less than 1MWh and the total electricity consumption of multiple small electricity users is greater than or equal to 1MWh, one green certificate can be aggregated and transferred for multiple small electricity users.

[0054] According to the above implementation mode, in the case where the power generation of a single distributed power generation entity is less than 1MWh but the total power generation of multiple power generation entities is greater than or equal to 1MWh, a green certificate can be issued for multiple entities in an aggregated manner, thereby avoiding the situation where distributed power generation entities whose power generation is insufficient to issue green certificates cannot obtain green certificates.

[0055] In one embodiment, obtaining the green electricity to be certified of each distributed resource subject among multiple distributed resource subjects corresponding to the aggregator includes: obtaining the contract text and smart contract of the aggregator from the blockchain; determining the first total transaction electricity of the aggregator from the contract text; decomposing the first total transaction electricity to obtain the first transaction electricity of each distributed resource subject; when the first total transaction electricity matches the second total transaction electricity of the aggregator calculated by the smart contract, and the first transaction electricity of each distributed resource subject matches the second transaction electricity of the corresponding distributed resource subject calculated by the smart contract, determining the green electricity to be certified of each distributed resource subject in this settlement based on the second transaction electricity of each distributed resource subject calculated by the smart contract; obtaining the remaining green electricity to be certified of each distributed resource subject in the previous settlement from the blockchain; summing the green electricity to be certified of each distributed resource subject in this settlement and the remaining green electricity to be certified of each distributed resource subject in the previous settlement, so as to update the green electricity to be certified of each distributed resource subject in this settlement.

[0056] It can be understood that the contract text is a contract signed in advance between the aggregator and its corresponding distributed resource entities, which can record the total transaction electricity of the aggregator within a certain period of time and the transaction electricity of each distributed resource entity.

[0057] It can be understood that the transaction volume of the aggregator and its corresponding distributed resource entities within a certain period of time can be calculated through smart contracts.

[0058] It can be understood that the first total transaction electricity volume matches the second total transaction electricity volume of the aggregator recorded in the smart contract in that the difference between the first total transaction electricity volume and the second total transaction electricity volume does not exceed a preset first threshold value.

[0059] It can be understood that, for any distributed resource entity, the first transaction power and its second transaction power match in that the difference between the first transaction power and the second transaction power does not exceed a preset second threshold.

[0060] It is understandable that green certificates can be issued to aggregators at regular intervals. It is understandable that in this example, except for the first time that the aggregator performs electricity settlement to issue green certificates, the above operation is performed, and the remaining green electricity to be issued in the previous settlement is added to the green electricity to be issued in this settlement to update the green electricity to be issued in this settlement. That is, the updated green electricity to be issued is used as the green electricity to be issued that ultimately needs to be issued a green certificate in this settlement.

[0061] It can be understood that the above steps S120 to S140 are performed based on the green electricity quantity to be issued for which a green certificate is ultimately required in this settlement.

[0062] According to the above implementation, each time a green certificate is issued, the remaining green electricity to be issued in the previous settlement needs to be considered, which can avoid the situation where the remaining electricity cannot be issued with a green certificate, thereby improving the efficiency of green certificate issuance.

[0063] In one embodiment, it also includes: summing up the first remaining electricity of each distributed resource subject in this settlement, and subtracting the product of the second quantity and the exchange standard electricity from the summed result to obtain the second remaining electricity of multiple distributed resource subjects in this settlement; when it is determined that the second remaining electricity is greater than zero and less than the exchange standard electricity, for each distributed resource subject, subtracting the sum of the electricity of the distributed resource subject in each common ownership green certificate from the first remaining electricity of the distributed resource subject in this settlement to obtain the remaining green electricity to be issued by the distributed resource subject in this settlement, which will be used in the next settlement request to the aggregator.

[0064] Exemplarily, taking the distributed resource subject as the power generation subject as an example, the second remaining power is: .

[0065] in, It means that after the issuance of green certificates for joint ownership to multiple power generation entities, the remaining electricity is still less than 1MWh, which is the second remaining electricity mentioned above.

[0066] For example, the issuance process of the common ownership green certificate can be as follows:

[0067] The first surplus power of each distributed power generation entity Sort by largest to smallest. Then, add the remaining power of the first one from the front to the back. , and a green certificate is issued for every 1MWh of electricity. In this way, the ownership of each power generation entity in the common green certificate can be allocated according to the proportion of electricity in the corresponding electricity of this green certificate. Assume that the electricity of each power generation entity in the corresponding electricity of the jth green certificate is , the ownership distribution is as follows:

[0068] .

[0069] For example, for the second remaining power , green certificates will not be issued temporarily.

[0070] Then, calculate the remaining green electricity to be issued by each distributed generation entity in this settlement Store the evidence on the chain and wait for the next settlement cycle.

[0071] in, The calculation formula is as follows:

[0072] .

[0073] For distributed power users, the above example can also be used to determine their remaining green electricity volume to be certified in this settlement.

[0074] According to the above implementation, when the remaining electricity amount of less than 1MWh is greater than zero after the issuance of green certificates for common ownership to multiple distributed resource entities, the remaining green electricity amount to be issued in this settlement can be determined for each distributed resource entity for use in the next settlement request to the aggregator.

[0075] In the above example method, it can be executed by the power trading center, and each data obtained by the execution can be uploaded to the blockchain for storage, so that it can be traced, confirmed, and flexibly traded or used in the future.

[0076] Figure 2 Schematic diagram of a blockchain platform according to an embodiment of the present invention.

[0077] like Figure 2 As shown in the figure, first, a blockchain platform consisting of multiple entities such as distributed power generation entities, small power users, aggregators, power grid companies, power dispatching centers, power trading centers, and regulatory agencies is constructed. Blockchain trusted metering devices are installed for distributed power generation entities and small power users, and blockchain nodes are deployed for other entities. Secondly, aggregators aggregate distributed resource entities, and distributed resource entities apply to join a certain aggregator and sign an agency contract with the aggregator. The aggregator acts as an independent entity to represent all its subordinate distributed resource entities in power market transactions. Thirdly, a green electricity trusted traceability mechanism for distributed resource aggregation is established. , collect 15-minute fine-grained distributed resource power generation and consumption related data and upload it to the blockchain platform. The aggregator will upload the power generation and consumption aggregation data, transaction process data, transaction decomposition data, etc. to the chain. The power trading center will upload transaction applications, results and other data to the chain. The power grid company will upload the online power data to the chain to establish a fine-grained traceability system for the entire life cycle of green electricity; design a multi-subject aggregated green certificate issuance and right confirmation mechanism, issue multi-subject aggregated green certificates based on aggregated transaction power and online power, and determine the ownership division ratio of green certificates based on the power generation and consumption ratio of each distributed resource entity, so as to realize multi-subject aggregated green electricity, traceability, right confirmation and flexible use of green certificates.

[0078] The following will be combined Figure 2 , introduces the blockchain platform, as follows:

[0079] 1. Build a blockchain platform for green electricity traceability and green certificate issuance

[0080] In the scenario where distributed resources are aggregated to participate in electricity market transactions, relevant entities include distributed power generation entities, small power users, aggregators, power grid companies, power dispatching centers, power trading centers, regulatory agencies, etc., building a multi-entity blockchain platform to provide trusted support for green electricity traceability and green certificate issuance services.

[0081] Among them, alliance chain technology is used to deploy blockchain nodes for aggregators, power grid companies, power dispatching centers, power trading centers, regulatory agencies and other entities to build a blockchain consensus network composed of multiple entities.

[0082] Among them, the scenario of distributed resource aggregation participating in electricity market transactions can be subdivided into distributed power generation entities aggregation participating in electricity market transactions and small power users aggregation participating in electricity market transactions.

[0083] Among them, as the source of green electricity, distributed power generation entities need to make reliable records of source data. A blockchain trusted metering device is installed for each distributed power generation entity. The blockchain client is deployed in the device to support the source power generation data to be directly uploaded to the chain. For distributed power generation entities that are fully connected to the grid, one blockchain trusted metering device is deployed to upload the power generation data to the chain. For distributed power generation entities that generate electricity for their own use and have surplus electricity connected to the grid, two blockchain trusted metering devices can be deployed, one for recording total power generation data and the other for recording online power data, which can simultaneously support the metering of self-generated and self-used electricity and the metering of online transaction electricity.

[0084] Among them, small-scale electricity users, as consumers of green electricity, also need to keep reliable records of their electricity consumption data. A blockchain trusted metering device should be installed for each small-scale electricity user. A blockchain client should be deployed in the device to support direct uploading of source electricity consumption data to the chain.

[0085] 2. Aggregators aggregate distributed resources

[0086] Aggregators can be specifically divided into virtual power plants and load aggregators. Virtual power plants can aggregate distributed power generation entities into a power generation entity, or aggregate small power users into a power user entity to participate in power market transactions. Load aggregators aggregate small power users into a power user entity to participate in power market transactions. The aggregation process is as follows:

[0087] (1) The distributed resource entity submits an aggregation application to the aggregator and simultaneously submits relevant power generation and consumption information such as installed capacity or power load;

[0088] (2) The aggregator reviews the relevant information of the distributed resource subject, agrees to allow the distributed resource subject that meets the requirements to join the aggregation team, and signs an agency contract with it to participate in power market transactions on its behalf;

[0089] (3) The distributed resource subject sends the relevant parameters of its blockchain trusted metering device to the aggregator, so that the aggregator can view and obtain the power data uploaded by it using the blockchain trusted metering device;

[0090] (4) The aggregator registers the multiple distributed resource entities it manages as a whole with the power trading center as power market entities and is eligible to participate in power market transactions.

[0091] 3. Green electricity credible traceability mechanism for distributed resource aggregation

[0092] Establish a green electricity data traceability mechanism for distributed resource aggregation, establish a fine-grained traceability system for source, network, and load, and solve the problem of complicated traceability paths caused by aggregators acting as intermediary agents.

[0093] For distributed power generation entities that participate in power market transactions, the processing process of their green power data is as follows:

[0094] (1) Each distributed power generation entity reports its power generation curve data to the aggregator, and at the same time collects 15-minute fine-grained power generation and other related data through the blockchain trusted metering device and stores it on the chain. Among them, the power generation curve is obtained based on the federated learning mechanism. Since the distributed power generation entities under the same aggregator are close to each other and the conditions such as light and temperature are similar, in order to improve the prediction accuracy of the power generation curve, multiple distributed power generation entities can be combined through data sharing to achieve higher-precision predictions. It should be noted that when establishing a federated learning training system, it is necessary to carry out different types of power generation such as photovoltaics and wind power separately. The specific steps are as follows:

[0095] (1.1) A power generation curve prediction model based on federated learning is established. The training models of each distributed power generation entity are as follows:

[0096] ;

[0097] .

[0098] in: They represent the sample feature set owned by the i-th distributed generation party, which mainly includes basic information of the power station such as designed power generation power, component type, tilt angle, and historical weather data such as temperature and humidity. The data dimensions of each generation party are the same; They represent the sample label sets owned by the i-th distributed generation party. In this model, the sample labels can be the power generation in a certain period of time, etc.; They represent the sample ID set owned by the i-th distributed generation party. Each distributed generation party has its own sample set with different IDs. They respectively represent the sample data sets owned by the i-th distributed generation party, i=1,2,…,n.

[0099] (1.2) Each participant uses their own sample data set to train their own model parameters , t represents the tth round of training and submission to the blockchain platform.

[0100] (1.3) After the federated learning smart contract collects the model parameters of all participants, it automatically calculates the total model parameters , the weighted average method can be used, the formula is as follows:

[0101] .

[0102] in, It represents the weight ratio of the model parameters of the i-th participant in the t-th round of training. The ratio can be the ratio of the number of samples of each participant to the total number of samples, the ratio of 1-the Euclidean distance between the model parameters of each participant and the model parameters of other participants to the total distance of all parties, etc.

[0103] (1.4) When and When the difference between them is less than a certain threshold, the training of the federated learning model ends, and each participant obtains the final model parameters generated by the smart contract.

[0104] (1.5) Each distributed generation party generates its own power generation curve based on the final model parameters.

[0105] (2) Aggregators receive the power generation curve data of all distributed power generation entities, and generate aggregated power generation curve data by superimposing the curves point by point. Aggregators participate in power market transactions as agents, declare information such as electricity volume and price, and store relevant information on the chain. The calculation formula for the power generation curve value of T aggregator at any time between 0-24 hours every day is as follows:

[0106] .

[0107] (3) The power trading center obtains all transaction declaration data, organizes and carries out power supply and demand matching, forms unconstrained clearing data, and stores the relevant data on the chain.

[0108] (4) The power dispatching center obtains the unconstrained clearing data submitted by the power trading center, conducts security verification, generates data such as constrained clearing and dispatching information, and stores them on the chain.

[0109] (5) The aggregator obtains constrained clearing data and signs a green electricity trading contract with the electricity purchaser based on the clearing information. The aggregator's contract includes the aggregator's total trading volume and may also include the trading volume of each distributed power generation party. The contract-related data is uploaded to the chain for evidence storage.

[0110] It is worth noting that when aggregators participate in electricity trading, they are allowed to conduct transactions such as contract transfer or contract repurchase on a monthly or shorter basis based on actual power generation and consumption conditions. They need to sign new contract transfer or contract repurchase agreements and upload relevant agreement information to the chain for evidence.

[0111] (6) The power grid company generates the aggregator's green power settlement information based on the total grid-connected power of each distributed power generation entity of the aggregator, the aggregator's contract power, user power usage, contract transfer and contract repurchase, and stores the relevant information on the chain.

[0112] Among them, the total grid-connected power of each distributed power generation entity is calculated based on the 15-minute fine-grained power generation collected by the blockchain trusted metering device. A smart contract for total grid-connected power calculation can be designed to achieve automatic calculation with the metering start time and end time as parameters. The total grid-connected power of the aggregator is equal to the sum of the total grid-connected power of each distributed power generation entity;

[0113] (7) The aggregator obtains its green power settlement information, decomposes the settlement results to each distributed power generation entity according to the grid-connected power of each distributed power generation entity, determines the green power settlement information of each distributed power generation entity, and stores the relevant information on the chain.

[0114] Among them, the decomposition of power generation settlement results can be automatically realized by using an artificial intelligence-based aggregator contract power extraction method. By intelligently extracting the aggregator contract text, the transaction power of each distributed power generation party in the contract can be obtained, and the result of the smart contract is calculated in combination with its total grid-connected power to determine the green power settlement information of each distributed power generation entity.

[0115] (8) The power trading center obtains the green power settlement information of the aggregator and the green power settlement information of each distributed power generation entity, and after verifying that the information is correct, generates the green certificate transfer information of each distributed power generation entity.

[0116] In summary, by uploading the 15-minute fine-grained green power generation data of each distributed power generation entity, aggregate declaration, transaction, settlement, and settlement decomposition and other full-process information to the chain, a trusted green electricity traceability mechanism is built for distributed power generation entities to participate in electricity market transactions in an aggregated manner, supporting distributed power generation entities to conveniently participate in green electricity transactions and green electricity full life cycle management.

[0117] For distributed power generation entities that participate in power market transactions, the processing process of their green power data is as follows:

[0118] (1) Small power users report load curve data to aggregators, upload the reported curve to the blockchain platform for evidence, and collect 15-minute fine-grained electricity consumption and other related data through blockchain trusted metering devices and upload them to the chain for evidence. Among them, the load curve can also be obtained based on the federated learning mechanism. Since the small power users under the same aggregator are close to each other and have similar living environments, in order to improve the accuracy of load curve prediction, multiple small power users can be combined to achieve higher-precision prediction through data sharing. It should be noted that when establishing a federated learning training system, it is necessary to carry out different types of electricity consumption such as electric vehicle charging, industrial and commercial users, and air-conditioning loads. The modeling process is similar to that in (I) and will not be repeated.

[0119] (2) The aggregator receives the load curve data of all small power users and generates aggregated load curve data by accumulating the load curve point by point. The aggregator participates in green power market transactions as an agent, declares information such as electricity volume and price, and stores the relevant information on the chain.

[0120] (3) The power trading center obtains all transaction declaration data, organizes and carries out power supply and demand matching, forms unconstrained clearing data, and stores the relevant data on the chain.

[0121] (4) The power dispatching center obtains the unconstrained clearing data submitted by the power trading center, conducts security verification, generates data such as constrained clearing and dispatching information, and stores them on the chain.

[0122] (5) The aggregator obtains constrained clearing data and signs a green electricity trading contract with the electricity seller based on the clearing information. The aggregator's contract includes the aggregator's total trading volume and may also include the trading volume of each small power user. The contract-related data is uploaded to the chain for evidence storage.

[0123] It is worth noting that when aggregators participate in electricity trading, they are allowed to conduct transactions such as contract transfer or contract repurchase on a monthly or shorter basis based on actual power generation and consumption conditions. They need to sign new contract transfer or contract repurchase agreements and upload relevant agreement information to the chain for evidence.

[0124] (6) The power grid company generates the aggregator's green power settlement information based on the total power consumption of each small power user belonging to the aggregator, the aggregator's contract power, contract transfer and contract repurchase information, and stores the relevant information on the chain.

[0125] The total electricity consumption of each small power user is calculated based on the 15-minute fine-grained electricity consumption collected by the blockchain trusted metering device. A smart contract for total electricity consumption calculation can be designed to realize automatic calculation with the metering start time and end time as parameters. The total electricity consumption of the aggregator is equal to the sum of the total electricity consumption of each small power user.

[0126] (7) The aggregator obtains the green electricity settlement information, decomposes the settlement results to each small electricity user according to the electricity consumption of each small electricity user, determines the green electricity settlement information of each small electricity user, and stores the relevant information on the chain.

[0127] Among them, the decomposition of electricity consumption settlement results can be automatically realized by using the artificial intelligence-based aggregator contract electricity extraction method. Through the intelligent extraction of the aggregator contract text, the electricity consumption of each small power user in the contract can be obtained, and the result of the smart contract is calculated in combination with their total electricity consumption to determine the green electricity settlement information of each small power user.

[0128] (8) The power trading center obtains the green power settlement information of the aggregator and the green power settlement information of each small power user, and after verifying that the information is correct, generates the green certificate transfer information of each small power user.

[0129] In summary, by uploading the 15-minute fine-grained green electricity consumption data of each small power user, aggregated declaration, transaction, settlement, and settlement decomposition and other full-process information to the chain, a trusted traceability mechanism for green electricity is established for small power users to aggregate and participate in electricity market transactions, supporting small power users to conveniently participate in green electricity transactions and the full life cycle management of green electricity.

[0130] 4. Issuance and division of rights of multi-subject aggregated green certificates

[0131] For the scenario where distributed resources are aggregated to participate in electricity trading, a multi-subject aggregated green certificate issuance and right allocation mechanism is designed to issue green certificates to each distributed resource subject, solving the problem that green certificates can currently only be issued to aggregators, resulting in distributed resource subjects being unable to obtain green certificates and their related interests being damaged.

[0132] First, green certificates are transferred to distributed power generation entities participating in the aggregated green electricity market transactions. The power trading center generates green certificate transfer information for each distributed power generation entity based on the green power settlement information of each distributed power generation entity, and issues green certificates to each distributed power generation entity. The details can be as follows:

[0133] (1) The power generation of the i-th distributed generation entity is For distributed power generation entities with online power generation exceeding 1MWh, a separate green certificate will be issued to meet the 1MWh power requirement, and the remaining power will be used to issue a common green certificate.

[0134] (2) If the power generation of a single distributed power generation entity is less than 1MWh and the total power generation of multiple power generation entities is greater than or equal to 1MWh, a green certificate will be issued to multiple entities in an aggregated manner, and the proportion of power generation contributed by each power generation entity will be calculated at the same time, and the corresponding proportion of the power generation entity’s ownership of the green certificate will be determined.

[0135] (3) For the remaining electricity whose aggregated power generation is still less than 1MWh , temporarily not issuing green certificates, and the remaining power generation information of each power generation entity Store the evidence on the chain and wait for the next settlement cycle.

[0136] Second, green certificates are transferred to small power users participating in the aggregated green electricity market transactions. The power trading center generates green certificate transfer information for each small power user based on the green power volume settlement information of each small power user, and issues a green certificate to each small power user. The details are as follows:

[0137] (1) For small power users whose electricity consumption exceeds 1MWh, green certificates with independent ownership will be transferred to meet their electricity consumption of 1MWh.

[0138] (2) In the case where the electricity consumption of a single small power user is less than 1MWh and the total electricity consumption of multiple small power users is greater than or equal to 1MWh, one green certificate will be aggregated for multiple small power users, and the proportion of electricity consumption of each small power user will be calculated at the same time, and the corresponding proportion of the ownership of the green certificate will be owned by the small power user.

[0139] (3) For the remaining electricity whose aggregated electricity consumption is still less than 1MWh, the green certificate will not be issued temporarily. The remaining electricity consumption information of each small power user will be stored on the chain and wait for the next settlement cycle.

[0140] The above calculation process can refer to the aforementioned related formulas and will not be described in detail here.

[0141] Through the above mechanism, green certificates can be issued or transferred in a shorter period of time, providing data support for subsequent green certificate transactions, green electricity accounting, carbon verification and other activities.

[0142] According to the above embodiments, it is possible to realize the aggregation of green electricity by multiple entities, the traceability of green certificates, the confirmation of ownership and the subsequent flexible trading or use.
