[0029] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0030] Faced with a wide variety of transaction types, a large number of trading entities and complex trading relationships, how to efficiently conduct electricity statistics and electricity traceability is a technical problem that needs to be solved urgently.

[0031] Based on this, the embodiment of the present invention provides a transaction electricity statistics and traceability method based on smart contracts, such as Figure 1 As shown, a transaction power statistics and traceability smart contract is deployed on the constructed alliance chain system. The method includes:

[0032] Step 101: Obtain each power transaction contract to be counted.

[0033] Among them, each power trading contract to be counted is a power trading contract that needs to be counted within a preset statistical period. The preset statistical period can be set according to actual business needs. For example, if the electricity data is set to be counted in months, each power trading contract to be counted is the power trading contract involved in the current statistical month. In addition, the power trading contract includes transaction information such as the seller, buyer, transaction name, transaction volume, transaction price (yuan / KWh), and transaction time. The transaction names include annual listing transactions for power grid companies to purchase electricity, annual centralized transactions, bilateral transactions, small hydropower sales company agency transactions, thermal power agency transactions, medium- and long-term listing transactions for power grid companies to purchase electricity, hydropower agency transactions, user-side pre-contract transfer transactions, power generation company-side pre-transfer transactions, user-side bilateral negotiated transactions for electricity, power generation company-side bilateral negotiated transactions for deviation electricity, user-side deviation electricity listing transactions, power generation company-side deviation electricity listing transactions, etc.

[0034] The embodiment of the present invention is mainly applicable to the statistics and traceability of annual power trading volume and trading volume. The execution subject of the embodiment of the present invention is a device or equipment capable of performing statistics and traceability of trading volume, such as a server.

[0035] For the embodiment of the present invention, in order to perform electricity statistics and electricity source tracing, it is necessary to obtain each electricity trading contract to be counted, for example, to obtain each electricity trading contract of the current statistical month (September). The embodiment of the present invention performs transaction electricity statistics based on transaction information and transaction contracts. Specifically, (seller, buyer, transaction name) can be used as the unique identifier of a contract, for example, (power sales company 001, user 001, transaction name 001), (power generation enterprise 001, user 001, transaction name 001), (power sales company 001, power sales company 002, transaction name 001), (power generation enterprise 001, power sales company 002, transaction name 001), (user 001, user 002, transaction name 001), etc.

[0036] Step 102: Classify the various power trading contracts to obtain various original conventional trading contracts, various prior transfer trading contracts and various deviation trading contracts.

[0037] Among them, the original conventional transaction contract is for users or power sales companies to purchase electricity from power generation enterprises. The prior transfer transaction contract and the deviation transaction contract are both power transactions on the user side and power generation enterprise side. Specifically, the power transaction on the user side is a power transaction in which both the seller and the buyer are users or power sales companies, and the power transaction on the power generation enterprise side is a power transaction in which both the seller and the buyer are power generation enterprises.

[0038] For the embodiment of the present invention, after obtaining each power trading contract, the power trading contracts can be classified in turn according to the time sequence of the medium- and long-term power transactions, and the power trading contracts can be classified into original conventional trading contracts, ex ante transfer trading contracts, and deviation trading contracts. Specifically, the trading contracts whose transaction types are user-side ex ante contract transfer transactions and power generation enterprise-side ex ante transfer transactions in the various power trading contracts are determined as the various ex ante transfer trading contracts; the trading contracts whose transaction types are user-side electricity bilateral negotiation transactions, power generation enterprise-side deviation electricity bilateral negotiation transactions, user-side deviation electricity listing transactions, and power generation enterprise-side deviation electricity listing transactions in the various power trading contracts are determined as the various deviation trading contracts; the trading contracts whose transaction types are power grid enterprise agency electricity purchase annual listing transactions, annual centralized transactions, bilateral transactions, small hydropower sales company agency transactions, thermal power agency transactions, power grid enterprise agency electricity purchase medium- and long-term listing transactions, and hydropower agency transactions in the various power trading contracts are determined as the various original conventional trading contracts.

[0039] After classification, the above-mentioned transaction contracts are processed in the corresponding processing order, which is the original regular transaction contract, the prior transfer transaction contract and the deviation transaction contract.

[0040] The embodiment of the present invention classifies medium- and long-term power transaction contracts into conventional transaction contracts, prior transfer transaction contracts, and deviation transaction contracts, and sequentially processes different types of medium- and long-term power transaction contracts based on these types, thereby reducing the types of power transaction contracts that need to be processed. On the premise of ensuring the correctness of the power statistics results, the power statistics process is simplified, the complexity of the processing process is reduced, and the interference of complex business logic on power statistics is eliminated.

[0041] Step 103: sequentially transfer the transaction electricity and transaction relationship of the seller in each of the prior transfer transaction contracts and each of the deviation transaction contracts to the buyer, so as to convert each of the prior transfer transaction contracts and each of the deviation transaction contracts into each of the regular transaction contracts.

[0042] The embodiment of the present invention takes the original conventional transaction contract as the basic data, and processes the user-side power transaction and the power transaction on the power generation enterprise side respectively, that is, the seller's traded electricity in the prior transfer transaction contract and the deviation transaction contract is allocated to the corresponding conventional power transaction contract according to the proportion of the seller's transaction contract electricity, thereby transferring the transaction electricity and the transaction relationship to the buyer.

[0043] For the above process, step 103 specifically includes: determining the original conventional transaction contracts related to the sellers in each of the prior transfer transaction contracts and each of the deviation transaction contracts; calculating the proportion of the transaction electricity in the original conventional transaction contract related to the seller; allocating the transaction electricity in each of the prior transfer transaction contracts and each of the deviation transaction contracts to the original conventional transaction contract or the new conventional transaction contract related to the buyer according to the proportion of the transaction electricity in the original conventional transaction contract related to the seller; and determining the allocated original conventional transaction contract or the new conventional transaction contract related to the buyer as the converted conventional transaction contracts.

[0044] Specifically, for the convenience of subsequent electricity statistics, the embodiment of the present invention simplifies the transaction contract information into (seller, buyer, regular transaction / pre-transfer transaction / deviation transaction, transaction electricity (yuan / KWh)), that is, before counting the electricity data, the embodiment of the present invention pre-processes the transaction contract data to remove information such as the transaction name, transaction price, and transaction time. When performing subsequent statistics, the embodiment of the present invention uses (seller, buyer) as the unique identifier for electricity statistics.

[0045] For example, the transaction information of a certain prior transfer transaction contract is (user 001, user 002, prior transfer transaction, transaction electricity Q). There are two original regular transaction contracts related to the seller (user 001), namely (power generation enterprise 001, user 001, regular transaction, transaction electricity Q1) and (power generation enterprise 002, user 001, regular transaction, transaction electricity Q2). Then, the transaction electricity is allocated according to the proportion of transaction electricity Q1 and transaction electricity Q2, and the following two transactions are generated: (power generation enterprise 001, user 002, regular transaction, transaction electricity Q×Q1 / (Q1+Q2)) and (power generation enterprise 002, user 002, regular transaction, transaction electricity Q×Q2 / (Q1+Q2)).

[0046] It should be noted that if, during the processing of a prior transfer transaction or a deviation transaction, the buyer has a transaction contract with the seller corresponding to the allocated transaction power, or the seller has a transaction contract with the buyer corresponding to the allocated transaction power, the transaction power is directly assigned to the power result in the prior transfer transaction or deviation transaction processing plus the transaction power of the existing transaction contract as the new transaction power of the transaction contract. Following the above example, if there is an original conventional transaction contract (power generation enterprise 001, user 002, conventional transaction, transaction power Q3), the new transaction power corresponding to the transaction is Q3+Q×Q1 / (Q1+Q2).

[0047] If, during the processing of a prior transfer transaction or a deviation transaction, the buyer does not have a transaction contract with the seller corresponding to the allocated transaction power, or the seller does not have a transaction contract with the buyer corresponding to the allocated transaction power, a new transaction contract is created, and the transaction power of the transaction contract is assigned to the power result during the prior transfer transaction or the deviation transaction. Following the above example, if there is no original conventional transaction contract between power generation enterprise 002 and user 002, a new conventional transaction contract is created (power generation enterprise 002, user 002, conventional transaction, transaction power Q×Q2 / (Q1+Q2)).

[0048] After processing the prior transfer transactions and deviation transactions, the transaction names of all transactions are "regular transactions". At this time, the embodiment of the present invention can simplify the transaction contract information used for electricity statistics to (seller, buyer, transaction electricity).

[0049] The embodiment of the present invention realizes the abstraction of the transaction relationship by abstracting the complex transaction relationship into a transaction contract in which one buyer corresponds to one seller, and ensures that the transaction relationship can be retained in the process of electricity statistics, which is convenient for the subsequent processing of the prior transfer transaction contract and the deviation transaction contract. In addition, the embodiment of the present invention can eliminate the transaction relationship between power users and power users or power sales companies, power sales companies and power users or power sales companies, and power generation enterprises and power generation enterprises through the processing of prior transfer transaction contracts and deviation transaction contracts, and process the transaction relationship as a transaction relationship between power users or power sales companies and power generation enterprises, thereby simplifying the transaction relationship.

[0050] Step 104: The converted conventional transaction contracts and the original conventional transaction contracts are used as the conventional transaction contracts to be processed, and based on the transaction electricity in the conventional transaction contracts to be processed, the total transaction electricity and the traceable electricity corresponding to the conventional transaction contracts to be processed are determined respectively.

[0051] Among them, the format of each pending regular transaction contract is (seller, buyer, transaction electricity), the seller is the power generation enterprise, and the buyer is the power user or power sales company.

[0052] For the embodiment of the present invention, the total transaction electricity can be calculated by adding up the transaction electricity in each conventional transaction contract to be processed. At the same time, the traceable electricity corresponding to each conventional transaction contract to be processed can be determined based on the transaction electricity in each conventional transaction contract to be processed. For this process, step 104 specifically includes: based on the transaction electricity in each conventional transaction contract to be processed, respectively calculating the actual electricity consumption and online electricity corresponding to each conventional transaction contract to be processed; based on the actual electricity consumption, online electricity and transaction electricity corresponding to each conventional transaction contract to be processed, determining the traceable electricity corresponding to each conventional transaction contract to be processed.

[0053] When calculating the actual electricity consumption corresponding to each pending conventional transaction contract, obtain the actual electricity consumption within the preset statistical period; determine the various first target conventional transaction contracts involved in the buyer of each pending conventional transaction contract in the pending conventional transaction contracts; calculate the first sum of the transaction electricity in each first target conventional transaction contract; calculate the proportion of the transaction electricity in each pending conventional transaction contract to the first sum; calculate the actual electricity consumption corresponding to each pending conventional transaction contract based on the proportion of the transaction electricity in each pending conventional transaction contract to the first sum, and the actual electricity consumption within the preset statistical period. The specific formula is as follows:

[0054] Actual electricity consumption (settlement electricity consumption) = actual electricity consumption within the preset statistical period × transaction electricity in a single transaction contract / the first sum of transaction electricity in each first target conventional transaction contract involved by the buyer

[0055] When calculating the online power corresponding to each pending conventional transaction contract, obtain the actual online power within the preset statistical period; determine the various second target conventional transaction contracts involved by the seller of each pending conventional transaction contract in the pending conventional transaction contracts; calculate the second sum of the transaction power in each second target conventional transaction contract; calculate the proportion of the transaction power in each pending conventional transaction contract to the second sum; calculate the online power corresponding to each pending conventional transaction contract based on the proportion of the transaction power in each pending conventional transaction contract to the second sum and the actual online power within the preset statistical period. The specific formula is as follows:

[0056] Online electricity = actual online electricity within the preset statistical period × transaction electricity in a single transaction contract / the second sum of transaction electricity in each second target conventional transaction contract involved by the seller

[0057] Furthermore, after calculating the actual power consumption and grid-connected power corresponding to each pending conventional transaction contract, compare the actual power consumption, grid-connected power, and transaction power, and take the minimum value of the three as the traceable power for each pending conventional transaction contract. The specific formula is as follows:

[0058] Traceable electricity = min (traded electricity, actual electricity consumption, online electricity)

[0059] Step 105: Calculate the balanced distribution electricity corresponding to the corresponding conventional trading contract based on the traceable electricity.

[0060] For the embodiment of the present invention, in order to calculate the balanced distributed electricity, step 105 specifically includes: determining each power generation enterprise and each user / power sales company involved in each of the pending conventional transaction contracts; calculating the proportion of remaining electricity of each of the power generation enterprises; calculating the untraced electricity corresponding to each of the pending conventional transaction contracts based on the actual electricity consumption and traceable electricity corresponding to each of the pending conventional transaction contracts; calculating the total untraced electricity of the pending conventional transaction contracts in which each user / power sales company is a seller among the users / power sales companies based on the untraced electricity corresponding to each of the pending conventional transaction contracts; calculating the balanced distributed electricity of the conventional transaction contracts related to each user / power sales company and each power generation enterprise based on the total untraced electricity of each user / power sales company and the proportion of remaining electricity of each power generation enterprise.

[0061] When calculating the proportion of surplus electricity of each power generation enterprise among various power generation enterprises, first calculate the sum of traceable electricity of pending regular transaction contracts involving each power generation enterprise as a seller, and the grid-connected electricity of each power generation enterprise; then subtract the grid-connected electricity of each power generation enterprise from the sum of traceable electricity to obtain the surplus electricity of each power generation enterprise; then calculate the sum of surplus electricity of each power generation enterprise based on the surplus electricity of each power generation enterprise; finally, calculate the proportion of surplus electricity of each power generation enterprise based on the surplus electricity of each power generation enterprise and the sum of surplus electricity. The specific formula is as follows:

[0062] The proportion of surplus electricity of power generation enterprises = the surplus electricity of power generation enterprises / the total surplus electricity of each power generation enterprise × 100%

[0063] After calculating the total untraceable electricity of each user / power sales company (buyer) and the remaining electricity ratio of each power generation enterprise (seller), locate the single transaction contract based on the buyer and seller, and calculate the balanced allocation electricity based on the total untraceable electricity and the remaining electricity ratio, and use the calculated balanced allocation electricity as the balanced allocation electricity of the transaction contract. The specific formula is as follows:

[0064] The balanced electricity distribution of a single transaction contract = the total untraceable electricity of the buyer × the proportion of the seller's remaining electricity.

[0065] It should be noted that if the seller and the buyer do not have a transaction contract but have a balanced allocation of electricity, a new transaction contract will be created and the balanced allocation of electricity of the transaction contract will be assigned the calculated balanced allocation of electricity.

[0066] The embodiment of the present invention reasonably distributes the portion of the power generation enterprise's grid-connected power that exceeds the actual power consumption of users (power users / power sales companies) through contract power tracing and balanced power distribution. It reasonably distributes the power generation enterprise's grid-connected power to users (power users / power sales companies) at the granularity of transaction contracts with reference to the power generation capacity of the power generation enterprise. The goal of allocating the power generation enterprise's grid-connected power to conventional transaction contracts can be achieved in two steps, which greatly improves the power tracing efficiency of transaction contracts and simplifies the logic of the power tracing process of transaction contracts.

[0067] In some embodiments, the transaction electricity statistics and transaction electricity traceability can be carried out in the form of smart contracts. Specifically, a consortium chain system is constructed, and a transaction electricity statistics and traceability smart contract is deployed on the consortium chain. When deploying the smart contract, write the transaction electricity statistics and traceability smart contract and conduct sufficient testing, initiate a smart contract chain request to put the transaction electricity statistics and traceability smart contract on the chain. Multiple nodes need to reach a consensus in the consortium chain system. After the consensus conditions are met, the smart contract is transferred to the "chained" state. After the smart contract installation process, the transaction electricity statistics and traceability smart contract is transferred to the "installation successful" state. After the smart contract deployment process, the transaction electricity statistics and traceability smart contract is transferred to the "deployment completed" state. When the "deployment completed" state is reached, the smart contract deployment process is completed.

[0068] It should be noted that an optional implementation method of the above-mentioned sufficient testing is to use multiple sets of simulated electricity trading data and electricity settlement data to run a test on the trading electricity statistics and traceability smart contract deployed in a test environment, and compare the results calculated by the trading electricity statistics and traceability smart contract with the data results pre-calculated using the above-mentioned multiple sets of simulated electricity trading data and electricity settlement data. If the two are consistent, it is determined that the tested trading electricity statistics and traceability smart contract has been fully tested.

[0069] It should be noted that the above-mentioned consensus reaching condition means that the number of consensus nodes in the alliance chain system that recognize the smart contract requested to be on the chain exceeds a certain proportion of the total number of consensus nodes in the alliance chain system that have voting rights for the smart contract. For example, the proportion is set to 50% or 2 / 3. Preferably, 50% is used as the setting proportion of the consensus reaching condition.

[0070] In addition, if the transaction electricity statistics and traceability smart contracts need to be adjusted according to the actual business scenario, the deployed smart contracts can be upgraded and the subsequent smart contract deployment process can be completed to deploy the transaction electricity statistics and traceability smart contracts for the new business scenario to the alliance chain system.

[0071] The embodiment of the present invention realizes the traceability of the electricity statistics process by using the transaction electricity statistics and traceability smart contract, so that the whole cycle can be traced. In addition, through the consensus protocol, it is guaranteed that only after the consent of multiple parties, the smart contract can be deployed to the alliance chain system to complete the electricity statistics and traceability, thereby ensuring the correctness, integrity, rationality and multi-party participation of the smart contract deployed to the alliance chain system.

[0072] In some embodiments, the transaction electricity statistics and traceability smart contract can also be split into multiple methods for implementation, and multiple data structures can be used to store original data, intermediate processing results, and final result data.

[0073] Specifically, the data structure of the smart contract for electricity trading statistics and traceability includes conventional electricity trading contracts, actual electricity consumption of users (settlement electricity), electricity consumption of power generation enterprises, electricity to be allocated by power generation enterprises, prior transfer trading contracts and deviation trading contracts. The smart contract method for electricity trading statistics and traceability includes inputting original data, querying contract information, prior transfer trading contracts / deviation trading contracts processing, power generation enterprise grid-connected electricity allocation, user actual electricity consumption (settlement electricity) allocation, contract traceability electricity allocation, and balanced allocation electricity calculation, such as Figure 2 As shown, the result of each of the above calculation processes or methods can be queried by calling the "Query Contract Information" method.

[0074] The conventional transaction contract data structure is used to store transaction contracts. The fields include transaction contract key value, buyer market number, seller market number, transaction electricity, actual electricity consumption (settlement electricity), online electricity, traceable electricity, balanced distribution electricity, etc. Among them, the four fields of transaction contract key value, buyer market number, seller market number, and transaction electricity are the data uploaded to the alliance chain system when the original data is entered. The remaining fields are the data that are continuously uploaded to the alliance chain system during the subsequent processing process. This can reduce the redundancy of the data uploaded to the alliance chain and improve the utilization efficiency of the data uploaded to the alliance chain.

[0075] The user's actual electricity consumption (settlement electricity) data structure is used to store the actual electricity consumption (settlement electricity) data of electricity users and power sales companies. The fields include electricity consumption key value, user's actual electricity consumption (settlement electricity), etc. This data structure completes data chaining in the alliance chain system when the original data is entered.

[0076] It should be noted that the transaction electricity statistics and traceability smart contract in the embodiment of the present invention does not distinguish between the user's actual electricity consumption and the user's settled electricity.

[0077] The power generation enterprise electricity data structure is used to store the original data, intermediate processing result data, and final result data of the power generation enterprise. The fields include the power generation enterprise's online power generation, traceable power generation, remaining power ratio, remaining power, etc. Among them, the online power generation is the original data, and the data is uploaded to the alliance chain system during the original data entry stage; the remaining fields are intermediate process data or result data generated in the subsequent processing process.

[0078] The data structure of the power generation enterprise's to-be-allocated electricity quantity is used to store the power plant numbers and the to-be-reallocated electricity quantity data used in the processing of prior transfer transaction contracts and deviation transaction contracts. The fields include the power plant number, to-be-reallocated electricity quantity data, etc.

[0079] The prior transfer transaction contract data structure is used to store the prior transfer transaction contract data. The fields include but are not limited to the prior transfer transaction contract key value, the buyer's market number, the seller's market number, and the transaction volume of the prior transfer transaction contract. All fields involved in this data structure are the original data that is uploaded to the alliance chain system during the original data entry stage.

[0080] The deviation trading contract data structure is used to store deviation trading contract data. The fields include the deviation trading contract key value, buyer market number, seller market number, trading volume of the deviation trading contract, etc. All fields involved in this data structure are the original data that is uploaded to the alliance chain system during the original data entry stage.

[0081] When entering the original data, the conventional power transaction contract, the actual power consumption of users (settlement power), the power generation enterprise's grid-connected power, the power generation enterprise's to-be-allocated power, the prior transfer transaction contract information, and the deviation transaction contract information are uploaded to the alliance chain system, such as Figure 3 As shown, the stub refers to the data stored in the alliance chain system.

[0082] When querying contract information, you can read and display the latest transaction contract information on the alliance chain system. Figure 4 As shown, by querying the contract information, the regular transaction contract information stored in the alliance chain system can be queried. The regular transaction contract information specifically includes the seller, buyer, transaction power, online power, user's actual power consumption (settlement power), balanced distribution power, etc. The stub refers to the data stored in the alliance chain system.

[0083] When processing prior transfer transaction contracts and deviation transaction contracts, the transaction electricity of the seller in the transaction contract is allocated to the buyer according to the actual situation based on the prior transfer transaction contract and the deviation transaction contract. Specifically, all transactions in which the seller participates in the transaction contract are read, and the proportion of the transaction electricity of each transaction contract in the total transaction electricity of all transaction contracts of the seller is calculated based on the transaction electricity of each transaction contract and the total transaction electricity of all transaction contracts of the seller. Then, the transaction electricity in the prior transfer transaction contract and the deviation transaction contract is allocated to the corresponding transaction contract in proportion (electricity proportion). If there is a transaction contract between the buyer and the seller, the electricity is added; if there is no transaction contract, a new transaction contract is created.

[0084] It should be noted that the pre-transfer transaction contract is carried out before the deviation transaction contract. Therefore, in the process of electricity statistics processing, the pre-transfer transaction contract needs to be processed first, and then the deviation transaction contract. In addition, in the process of processing the pre-transfer transaction contract, the order of processing the pre-transfer transaction contract will affect the proportion of the transaction electricity of a single transaction contract in the seller's transaction contract when processing a single pre-transfer transaction contract, and thus affect the processing result of the pre-transfer transaction contract.

[0085] Based on this, when processing a prior transfer transaction contract, the transaction electricity statistics and traceability smart contract sorts the prior transfer transaction contracts from large to small according to the transaction contract key value of the prior transfer transaction contract, and processes the prior transfer transaction contracts in the sorted order; similarly, the deviation transaction contract is processed in the same way.

[0086] It should be noted that both the prior transfer transaction contract and the deviation transaction contract have two types: the user side and the power generation enterprise side. The seller and the buyer of the prior transfer transaction contract and the deviation transaction contract on the user side are both power users or power sales companies, and the seller and the buyer of the prior transfer transaction contract and the deviation transaction contract on the power generation enterprise side are both power generation companies. That is, in the prior transfer transaction stage and the deviation transaction stage, only power users or power sales companies are allowed to transfer power resources with power users or power sales companies, or between power generation companies, and power resources are not allowed to be transferred between power generation companies and power users or power sales companies.

[0087] Since in conventional transaction contracts, power generation enterprises are sellers and power users and power sales companies are buyers, the prior transfer transaction contracts or deviation transaction contracts include two types of transaction contracts on the user side and the power generation enterprise side. In order to achieve the purpose of convenience and efficiency, the embodiments of the present invention use different methods to process the prior transfer transaction contracts and deviation transaction contracts when processing the two types of contracts.

[0088] During the processing process, since data can only be uploaded to the chain once a method is called, the prior transfer transaction contract and deviation transaction contract processing methods will uniformly upload the processing results to the alliance chain system after the entire processing process is completed.

[0089] When calculating the amount of electricity that a power generation enterprise has on-grid, Figure 5 As shown, according to the proportion of the transaction electricity in a single conventional transaction contract of a power generation enterprise in the total transaction electricity of all conventional transaction contracts of the power generation enterprise, the grid-connected electricity of the power generation enterprise within the preset statistical period is allocated to all conventional transaction contracts of the power generation enterprise, so as to complete the grid-connected electricity allocation of all power generation enterprises participating in the transaction within the preset statistical period.

[0090] When calculating the user's actual electricity consumption (settlement electricity), if Figure 6 As shown, according to the proportion of the transaction electricity in a single regular transaction contract of the power user / power sales company in the total transaction electricity of all regular transaction contracts of the power user / power sales company, the actual electricity consumption (settlement electricity) of the power user / power sales company is allocated to all regular transaction contracts of the power user / power sales company. In this way, the allocation of actual electricity consumption (settlement electricity) of all power users and power sales companies participating in the transaction within the preset statistical period is completed.

[0091] When calculating the contract traceability electricity, the smaller of the transaction electricity, actual electricity consumption (settlement electricity) allocation results, and online electricity allocation results of a single conventional transaction contract is taken, and the minimum value of the three is used as the contract traceability electricity of the conventional transaction contract. In this way, all conventional transaction contracts within the preset statistical period are traversed to complete the traceability electricity allocation of all conventional transaction contracts within the preset statistical period.

[0092] When calculating the balanced distribution of power, Figure 7 As shown, based on the untraceable settlement electricity of the buyer (power user / power sales company) of a single conventional transaction contract and the proportion of the remaining electricity of the seller (power generation enterprise) in the total remaining electricity of the power generation enterprise, the balanced allocation electricity of the conventional transaction contract is calculated. In this way, all conventional transaction contracts within the preset statistical period are traversed to complete the calculation of the balanced allocation electricity of all conventional transaction contracts within the preset statistical period.

[0093] The embodiment of the present invention provides a method for counting and tracing the transaction electricity based on smart contracts. By classifying each power transaction contract into a conventional transaction contract, a prior transfer transaction contract and a deviation transaction contract, and transferring the transaction electricity and transaction relationship of the seller in the prior transfer transaction contract and the deviation transaction contract to the buyer, that is, after converting into a conventional transaction contract, the transaction electricity and the traceable electricity are counted, which can reduce the types of power transaction contracts that need to be processed, simplify the transaction relationship, and thus simplify the electricity statistics and traceability process, eliminate the interference of complex business logic on electricity statistics and traceability, and thus improve the efficiency of electricity statistics and electricity traceability. In addition, the embodiment of the present invention can reasonably allocate the part of the power generation enterprise's online electricity that exceeds the actual electricity consumption by calculating the balanced distribution of electricity, thereby solving the problem of the difference between the power generation enterprise's online electricity and the actual electricity consumption.
