Description

Block chain-based energy transaction method, computing equipment and storage medium

Technical Field

The present invention relates to the field of blockchain, and in particular, to a blockchain-based energy transaction method, a computing device, and a storage medium.

Background

The green certificate is an important certificate for checking the fulfillment of the certificate in the quota system framework. To maintain marketization, and ensure that the green license can represent the true value of sustainable power generation, the life cycle of the green license must be comprehensively planned. The three stages of circulation of the green license are respectively issuing, trading and checking.

Green license issuance is an important step prior to green license marketing, and can ensure green license standardization and circulation legitimization from the source, the whole process of verification includes qualification inspection, power generation metering, green license generation and signature verification, and first, the government will conduct qualification verification on renewable resource suppliers to determine whether renewable energy sources can be provided. On the demand side of renewable resources, part of end users will be "producers" and renewable energy suppliers meeting the green authentication requirements are distributed on both sides of the source load, and the number will be greatly increased. The manufacturer passing the audit will upgrade or replace the certificate and calculate the corresponding green certificate by the company according to the conversion requirement of 1 MW/hour. Finally, after the supervision and inspection mechanism examines and checks, the green certificate is issued.

Returning to fig. 1, as shown in fig. 1, the blockchain-based energy transaction method of the present invention first performs step 110: and determining the energy Internet surfing metering according to the generated energy of the equipment used by the supplier. The green power certificate is called as a green certificate for short, is an electronic certificate with a unique code identifier issued by the country on the internet of non-water renewable energy sources at every megawatt hour of power generation enterprises, and is a unique certificate serving as green environmental rights.

The green certificate is an important certificate for checking the fulfillment of the certificate in the quota system framework. To maintain marketization, and ensure that the green license can represent the true value of sustainable power generation, the life cycle of the green license must be comprehensively planned. The three stages of circulation of the green license are respectively issuing, trading and checking.

Green license issuance is an important step prior to green license marketing, and can ensure green license standardization and circulation legitimization from the source, the whole process of verification includes qualification inspection, power generation metering, green license generation and signature verification, and first, the government will conduct qualification verification on renewable resource suppliers to determine whether renewable energy sources can be provided. On the demand side of renewable resources, part of end users will be "producers" and renewable energy suppliers meeting the green authentication requirements are distributed on both sides of the source load, and the number will be greatly increased. The manufacturer passing the audit will upgrade or replace the certificate and calculate the corresponding green certificate by the company according to the conversion requirement of 1 MW/hour. Finally, after the supervision and inspection mechanism examines and checks, the green certificate is issued.

Currently, new energy enterprises need to deal with green certificates and provide related data, such as: approval documents, electric charge invoices, bank remittance vouchers and the like. The national renewable resource management information system can audit and issue environmental protection certification monthly, has complicated procedures, time and labor waste for audit and low efficiency, and severely restricts the transaction of enterprises.

The invention adopts a PBFT consensus mechanism, and can ensure that the data on the chain has high tamper resistance. Specifically, a transaction platform may be deployed in a computing device. Suppliers may be implemented on renewable energy supplies. The energy source may be implemented as a renewable energy source. The energy online metering can be realized by renewable energy online metering after renewable energy suppliers use equipment to generate electricity, the transaction platform determines renewable energy online metering according to the generated electricity of the equipment,

subsequently, step 120 is performed to issue a green license to the provider based on the energy internet surfing metrics. Specifically, 1 MW/hour can correspondingly generate and issue a green syndrome. The green evidence is also recorded when issuing. When issuing a green certificate to a provider according to energy internet surfing metering, broadcasting the issued green certificate information to one or more other nodes through a main node; after receiving the green license information, other nodes rebroadcast the green license information; the master node and other nodes first send information that the authentication is consistent to the provider. A master node of a blockchain is included in a computing device, and other nodes of the blockchain may be deployed in the computing device or in other computing devices, with communicative coupling between the nodes.

Fig. 3 shows a schematic diagram of an authentication process according to an exemplary embodiment of the invention. As shown in fig. 3, when the renewable energy company applies for green certificates, a request is sent to a main node according to the specification, then the main node broadcasts to another node, and the rest nodes calculate and replay the number of green certificates proposed by the main node according to the negotiation targets, all the effective nodes agree, and the result of the agreement is fed back to the applicant, thus completing the authentication of the whole network.

Subsequently, step 130 is performed, in response to the consumer purchasing the green certificate, sending a transaction endorsement to the consumer in accordance with the endorsement node.

Subsequently, step 140 is performed, in response to the consumer purchasing the green certificate, sending a transaction endorsement to the consumer according to the endorsement node.

According to one embodiment of the invention, the computing device includes nodes, and the types of the nodes are an identity certificate management node (CA), an endorsement node (Endorser), a commit node (Committer) and an ordering node (Orderer). The function of each node is as follows.

CA node: the authorization and access of nodes in the network are performed by CA nodes, and various types of nodes are correspondingly authorized by utilizing the release and revocation of digital certificates, so that a standardized public key infrastructure (public key infrastructure, PKI) system is realized.

Endorser node: the transaction proposal is received from a client software tool development interface (software development kit, SDK), correctness checking is performed, simulation is performed, and after the success result is confirmed, the client SDK is returned.

Committer node: by obtaining the sorted blocks from the Orderer nodes, the transactions in the blocks are finally verified. Once approved, legal transactions may be conducted and recorded in a blockchain book.

Orderer node: accept those services that have been endorsed a sufficient amount and sort them into new blocks.

In the present invention, all green certificates are delivered in the form of a transaction uplink. In internal transactions, the platform is responsible for the uplink of the transaction; for off-site marketing, this is done by the party selling the green license. Whether a platform or a terminal, needs to access and run the blockchain network through the DK client.

Fig. 4 shows a schematic diagram of a transaction uplink according to an exemplary embodiment of the invention. As shown in fig. 4: the standardized green certificate transaction flow includes the following processes.

Transmitting an authorization request in response to the provider or consumer; the provider or consumer is authorized according to the management node so that the provider or consumer can send transaction information. After the CA node grants the client SDK, the renewable energy provider, the quota obligation undertaking party and each transaction platform are qualified to access the blockchain, and interact with the regional network through the SDK client. The CA node can specifically send transaction information to renewable energy suppliers, consumer ends and transaction platforms through SDK clients deployed by the CA node.

When the consumer purchases the green certificate, the private key is used for encrypting the purchase information, and the encrypted purchase information is sent; the method of the invention further comprises the following steps: in response to the consumer purchasing the green certificate, the encrypted purchase information is decrypted using the public key and the authorization legitimacy of the purchase is verified. Specific: the client SDK delivers the transaction message to the endoser node. The transaction platform and the off-site transaction send transaction information to the Endorser by the seller, including a seller account address, a purchase account address, a transaction timestamp, a transaction green certificate number and a transaction price. The seller needs to use the private key for data processing.

The endoser node sends the transaction to the client SDK interface and endorses. After the proposal is received by the endoser node, the public key is used for verifying the authorization legitimacy of the service (such as whether the node is authorized or not), then the protocol is used for verifying the rationality of the service (such as whether the provider has enough green certificates or not), after the logic verification is finished, the transaction is simulated, the service is recorded, and the record is fed back to the client. The record includes key-value pairs.

The client SDK submits the classification requirements to the Orderer node. If the client receives a large number of endorsements, a sorting request can be sent to the Orderer node, and sorting can be performed in time sequence during sorting. All unassociated transactions in the Orderer node group are ordered and encapsulated using the Paxos protocol.

The Orderer node returns the ordered result and the new block to the Committer node. In the Orderer node group, data is distributed if the number of transactions in the queue reaches a critical threshold or will begin to sell within a certain period of time. After the packet is completed, the Orderer node transmits the new block of data to the Committer.

The submitting node adds the data block to the ledger of the blockchain of the corresponding transaction type after the data fast check passes. Specific: and finally checking the Committer node, and synchronizing the account book with the Endorser node. After the Committer node receives a new data block, a final check will be made for transactions in this data block. When the audit is finished, transaction is carried out, and the local file and key value pair are updated.

Issuing a green certificate to a provider according to the energy online metering comprises: after issuing the green certificate to the consumer, the endorsement node acquires the account book added with the data block from the submitting node and stores the account book. The endoser node will periodically synchronize the local ledger on the Committer node.

The Committer node passes the results of the transaction to the client SDK. The Committer node transmits the results of the transaction back to the client SDK node after the final verification is completed. At this point, the transactor can see the delivery of the green credentials.

According to one embodiment of the invention, the data block includes energy information of energy provided by a provider corresponding to the green license, the energy information including a green electricity consumption percentage, a green electricity consumption and a green energy category.

In the electric power market, in various types of electric power supply systems such as wind power, photovoltaic, hydroelectric power and thermal power, the proportion of electric power components such as wind power, photovoltaic, hydroelectric power and thermal power is generally not determined by an electric power supplier and a user. The green electricity traceability measurement can reflect which green resource the consumer consumes in a specific time, and the proportion and value of each green energy source to the consumed electric energy. By using the micro-grid, the composition of the power system, the degree of environmental contribution, and the clean energy utilization efficiency can be directly grasped. The consumption condition of the green energy of the micro-grid is predicted by a method of real-time mining analysis and normalized comprehensive evaluation, so that the mobile sharing and consultation of the green power information are better realized for citizens, and the participation and interaction of the public are enhanced. By selecting a consensus mechanism in the blockchain technology, the transaction data is processed in real time, so that the slow running and real-time running of the system are ensured, and each participant in the whole transaction system can dynamically recognize the system.

In order to enable customers of the micro-grid to realize green power tracing, hydropower, photovoltaic, wind power and the like of the power customers can be accurately divided, and the whole structure of the green power tracing system is adopted.

Fig. 5 shows a schematic diagram of a green power traceability system according to an exemplary embodiment of the invention. The green power tracing system identifies and links objects such as green power consumption, green energy types and the like through data collection in a agreed mode, and meanwhile, relevant information is input into the blockchain database, so that a foundation is laid for tracing and tracing of green power. The functions of basic information management, information acquisition of each link, link association, inquiry and the like of the green power tracing system are the core of the green power tracing system. The consumer can trace the source through the system to obtain a return result, wherein the return result comprises node summaries of the green electricity consumption percentage data nodes in the green electricity consumption percentage database, the node summaries of the green electricity consumption nodes in the green electricity consumption percentage database and the node summaries of the green energy type nodes in the green energy type database.

The invention can also carry out carbon transaction through a platform in a mode of carbon emission right transaction, and the national evidence voluntary emission reduction (CCER). The participants in the carbon transaction are: buyers and sellers of carbon emissions, carbon emissions check consultation institutions, governments and third party platforms. Therefore, the present invention builds multiple service modes based on blockchain technology to meet various demands.

Fig. 6 illustrates a relationship between the bodies of the trading platform according to an exemplary embodiment of the present invention. All traders receive a public and private key and are monitored in real time by each individual trader with the CCER's registry to determine their carbon dioxide emissions and reduced amounts for trading. In the trading of carbon emissions rights, the trading of carbon emissions amounts will be performed in the trading platform of carbon emissions rights and the CCER, respectively. Based on the conversion of the smart contract, the CCER emissions reduction may be converted to carbon emissions and added to the market. After the transaction is completed, the modification of the property right for carbon emissions and CCER emissions reduction in the transaction should be performed according to the records, and the new property right transfer case should be registered in real time. Finally, all users' carbon emissions rights are fully retracted by the government to clear the already reduced emissions. In addition, in the blockchain system, the government and third party platforms can also be enabled to conduct carbon emission check in real time and conduct real-time monitoring on the carbon emission check, so that financial risks are prevented.

The invention aims at CCER resources scattered in the micro network, and can utilize CCER enterprises based on the blockchain technology to integrate services in the micro network. The mechanism integrates CCER resources dispersed in a micro-network and then performs the transaction in domestic carbon emission rights.

Fig. 7 shows a schematic diagram of a ccor asset aggregation proxy operation system architecture within a micro-grid according to an exemplary embodiment of the present invention. The users of each micro-grid react according to the compensation price provided by the aggregation agent of the respective region, and the enterprises integrate to the maximum extent according to the CCER resources of the respective region, so that the maximum benefit is obtained.

The blockchain in the invention can be specifically realized as a green license transaction blockchain, and the intelligent ammeter can accurately record the use condition of renewable energy sources and issue green licenses according to internal relevant regulations. All companies with green license can buy and sell in green license licensed market, renewable energy companies can obtain government subsidies by selling green license, fossil energy companies can obtain green license in green license form, limit is completed, and subsidized green power company is provided in market mode. All green certificate transactions are carried out through chains, so that not only can the reliability of the service be ensured, but also the supervision process can be reduced.

The blockchain in the present invention may also be embodied as a carbon emissions trading blockchain: the CCER is a combination of certified renewable energy sources and emission abatement programs such as agriculture, forestry and carbon emissions. While the carbon quota is calculated from its own internal law, from its historical emissions on the chain, and is public and transparent. The intelligent ammeter counts the carbon dioxide emission amount of the traditional fossil power generation station during the current week, and if the carbon dioxide emission amount in the market is less than that of the intelligent ammeter, the rest carbon dioxide can be emitted to the market; if the actual carbon dioxide emissions in the current market exceeds the total emissions of the business, the business becomes a buyer of the carbon emissions transaction. While carbon quota is generated according to internal rules, according to historical carbon emissions on the chain, and is public and transparent.

FIG. 8 illustrates a schematic diagram of a federated marketplace mechanism, according to one exemplary embodiment of the present invention. The interplay of the two transaction chains in fig. 8, because some renewable resources meet both green certificates and the ccir requirements in carbon emissions, must synchronize the issuance of green certificates with the data of carbon emissions to reduce the number of repetitions before the collaboration takes place. After the green certificate and the carbon emission rights expire, the company holding the green certificate can convert the green certificate and the carbon emission rights into balance of the carbon emission rights according to the marginal pricing of the current green certificate and the carbon emission rights, and then the green certificate and the carbon emission rights are put into the market again for transaction, so that the whole distribution of the green certificate and the carbon sources is achieved. On the basis, on the basis of market-based transactions and quotations, a general intelligent contract based on green certification and green emission is proposed. The utility company is part of the power market and must register a node account. If the buyer and the seller confirm the intelligent contract, the contract can be called to exchange the buyer and the seller.

As shown in fig. 8, green certification and carbon emission allowance determination is made by government and regulatory authorities for individual producers and consumers participating in the market prior to the start of the market quota system cycle; each market member registers an account number in the blockchain and returns a unique public key and a private key of each user to each person; the regulatory body builds a framework of intelligent contracts according to a market mechanism and a quotation mechanism.

The qualified renewable energy power generation enterprises meter the green power through the intelligent electric meter and acquire corresponding green certificates; the intelligent instrument performs detailed statistical analysis on the carbon emission of each production and consumption unit; each producing party encapsulates the data of the green certificate and the carbon emission right list according to the own requirements, including the volume of the transaction and the price. .

In the access of the user, the user can use the accessed address to call the contract, set transaction objects, deadlines, automatic execution terms and the like, sign by using own private keys to ensure the correctness of the contract, and pair the bids of various producers and consumers on the basis of continuous bi-directional auction (continuous double auction, CDA)

The implementation of the agreement is broadcast in the regional energy network in the form of P2P, while the latest contracts are integrated in the network of the trading market in the form of blocks.

The authenticated contracts are spread in the blockchain and exist in the blockchain, upon which access is made by the node on the client interface. Once the transaction begins, a request is made, the clearing contract is then mapped and cleared by the state machine, then transfers are made according to the specific circumstances of each transaction, and confirmation by certain nodes is made during the specified time period, then the running of the intelligent contract is performed.

The green certificates and the total amount of carbon emissions during one cycle of each producer and consumer are settled prior to the quota formation cycle, and green certificates exceeding the quota can compensate for carbon emissions exceeding the quota. The green certificates of the various producers and the carbon emission weights are counted to determine the quota of the next stage.

The invention is based on the Bayesian fault-tolerant mechanism to issue certificates, and adopts the PBFT consistency technology, so that the data has stronger non-tamper property, and the market security problem caused by data tampering and data errors can be furthest reduced in the authentication and transaction process; the PBFT algorithm does not depend on the token, and is free from achieving consistency through large-scale data calculation, and can shorten the consistency verification time and improve the overall execution efficiency. The delay of the PBFT protocol may reach 2-5 seconds, depending on more than 100 nodes in the network. Under the condition that 4200 ten thousand green certificates are issued annually for more than 400 renewable energy enterprises, the execution effect is not lower than that of a general issuing and trading mode.

On the basis of ensuring the reliability and safety of the transaction, the blockchain technology is adopted, and the verification of green certificates and the feasibility of the transaction are researched. The PBFT technology is subjected to demonstration analysis from three angles of safety, fairness and execution efficiency, and the PBFT protocol has no obvious negative effect on the efficiency of the whole system and has popularization and use capabilities.

According to the invention, the green power tracking mode can provide basis for issuing the green certificate and calculating the carbon quota, so that the rewarding or punishing of the submitted green certificate/carbon tax is avoided. When 'low-price surfing' is implemented, the current electric power market trading mode cannot fully reflect the environmental protection value of clean energy, and 'green evidence' is needed. The issuing of the green certificate and the accounting of the quota are required to depend on the source of the green power, and the digital certificate is also attached to the green certificate to be used as the unique number of the green certificate. At present, the national energy agency only issues green certificates for large wind power plants and solar power stations, so that distributed photovoltaic power generation, wind power, solar energy and the like which are not listed in the subsidy range do not have green certificates. However, in the load side, since the renewable energy density is continuously increased, the green electricity can be used for tracking, the green authentication is performed on a small-scale distributed power supply which is not approved by the national energy agency, and after the green certificate is issued, the electricity price of the project cannot be obtained. By tracing the green power, the correctness of green authentication can be fundamentally ensured, thereby preventing secondary use. The conclusion obtained by calculating the actual flow of the electric power flowing in the power grid has a certain guiding significance for the marketization pricing of the electric power.

Around the interrelation among the green electricity tracing method, the green card transaction platform scheme and the green card transaction uplink, the following three aspects are researched: firstly, determining which green energy is provided by the electric energy consumed by a user of the micro-grid in a certain period, and the proportion and the value of each consumed power by utilizing an integrated data integration and identification technology; secondly, on the basis, a green certificate exchange mechanism based on a blockchain technology is introduced, so that a consumer can better know the green certificate resource held by the consumer, thereby reducing the cost of purchasing the green certificate and providing support for purchasing the green certificate required by the consumer; based on the above, the present disclosure provides a process of using blockchain technology to perform the uplink of green certificates, integrating the process into the market to perform the uplink process by green certificate sellers, and using the SDK interface of the Fabric client to complete the access and operation of blockchain, thereby improving the service efficiency between each client.

In the traditional green card transaction, firstly, an off-site user bypasses an operator of a platform to perform green card conversion; in the whole green authentication process, due to the authentication characteristic, the system needs to be synchronously tracked and asynchronously upgraded by different authentication institutions. The green certificate transaction system of the blockchain technology has the following characteristics: reading and asynchronous data updating of a plurality of users can be realized; supporting asynchronous updating of a database; and ensuring the safety and consistency of the data.

The carbon trading system based on the blockchain technology integrates carbon sources in the scattered micro-grid, so that the carbon sources are added into the domestic carbon right market, the whole trading process is quickened, and the trading efficiency among all users is improved. And secondly, establishing a combined market of green license and carbon right exchange, and converting the residual green license resource into a carbon asset through the exchange of the green license and the carbon asset, thereby providing a certain reference for the carbon emission capacity of a user. Finally, according to the common green and low-carbon targets, a green certificate and carbon combined market trading mechanism design is provided, and the overall optimal distribution of green certificates and carbon emission is utilized to promote sustainable development and reduce carbon dioxide emission of conventional fossil fuels, so that fuel consumption and energy conversion are promoted.

For small-scale CCER users of the CCER in the micro-network, the invention provides a new way for the carbon emission of enterprises, thereby improving the comprehensive benefits of the enterprises. Before the integration of micro-grid CCER assets, agents can utilize their own information to make predictions, thereby reducing uncertainty in decisions of companies, and thus obtaining assets of CCER available for transaction, and forming a more reasonable purchasing scheme. After the prediction of the resource information is completed, the aggregation proxy may integrate the assets of the CCER into the domestic carbon trade market, thereby capturing benefits.

On the basis of the common goal of green and low carbon, the invention provides a combined market trading mechanism of green certificates and carbon, which can stimulate the development of renewable energy sources through the optimal distribution of green certificates and carbon emission, and can limit the emission amount of conventional fossil energy sources. Meanwhile, in order to ensure the safety, high efficiency, information disclosure and transparency of the green power and carbon combined market, an intelligent contract-based method is also provided, namely, a green power company and a traditional fossil energy company are connected together, green certificates and carbon emission are optimally distributed on the whole, so that the development of renewable energy sources is promoted, and the emission of the traditional fossil energy sources is restrained.
