Description

Technical Field

[0001] This invention relates to the field of integrated energy technology, and more specifically to a blockchain-based integrated energy peer-to-peer trading system. Background Technology

[0002] The development and application of integrated energy service systems help improve energy efficiency, and building such systems has become an important future development direction in the energy sector. With the advent of the big data era and the development of blockchain technology, new possibilities have emerged for the creation of integrated energy service systems. Leveraging these new technologies will undoubtedly bring new vitality and dynamism to integrated energy services.

[0003] Existing blockchain-based integrated energy service systems can be functionally divided into four subsystems: energy supply subsystem, conversion subsystem, transmission subsystem, and terminal subsystem. Through the division of labor and cooperation among these subsystems, energy transactions between the service providers and customers can be realized.

[0004] However, in existing blockchain-based integrated energy service systems, each subsystem on the blockchain needs to store not only transaction information but also all the system's physical information. After multiple transactions, the transaction information on the subsystems increases significantly, causing excessive system memory and a dramatic increase in the overall blockchain capacity. Furthermore, after each transaction, each subsystem records the transaction information again, resulting in a lot of redundant information. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a blockchain-based integrated energy peer-to-peer trading system that integrates and manages information from each transaction, thus solving the technical problems of memory overload and excessive redundant information in existing blockchain-based integrated energy service systems.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] This invention provides a blockchain-based integrated energy peer-to-peer trading system, comprising:

[0010] The energy supply subsystem is used to input energy into the integrated energy service system;

[0011] Terminal subsystems, including supplier and receiver terminal subsystems, are used to provide energy or receive and consume energy;

[0012] The adjustment subsystem is used to delete transaction information from other subsystem nodes after a transaction is completed, and record the transaction information in the adjustment subsystem.

[0013] The feedback subsystem is used in conjunction with the adjustment subsystem to inquire with both parties to the transaction whether they can delete the transaction information recorded in the adjustment subsystem, that is, to completely delete the transaction information.

[0014] Preferably, the system further includes: a conversion subsystem,

[0015] The conversion subsystem converts the energy type input by the power supply subsystem into the energy type required by the receiving terminal subsystem.

[0016] Preferably, the system further includes: a transmission subsystem.

[0017] The transmission subsystem is used to deliver the converted energy to the receiving terminal subsystem.

[0018] Preferably, the feedback subsystem is also used to enable bidirectional information transmission between the supplier's terminal subsystem and the receiver's terminal subsystem.

[0019] Preferably, when the adjustment subsystem performs the deletion of transaction information in other subsystem nodes, it includes:

[0020] After a transaction is completed, the reconciliation subsystem deletes information about the transaction from other subsystems and records it only in this subsystem. At this point, only the reconciliation subsystem has recorded the transaction information. The reconciliation subsystem will then ask both parties to the transaction whether they allow the deletion of the transaction information in the reconciliation subsystem. If both parties allow it, the transaction information in the reconciliation subsystem will be deleted, thus permanently deleting the transaction information. If neither party allows it simultaneously, the transaction information will remain in the reconciliation subsystem, and both parties can view and reference it until the maximum destruction period agreed upon by both parties expires, at which point the reconciliation subsystem will delete the transaction information.

[0021] Preferably, when the adjustment subsystem performs the deletion of transaction information in all subsystem nodes, it further includes:

[0022] If one or both parties have objections to a transaction, they can provide feedback through the feedback subsystem. After both parties reach an agreement, the transaction will be terminated, and the adjustment subsystem will delete information about this transaction from other subsystems and will not record this transaction information.

[0023] Preferably, the transaction methods of the blockchain-based integrated energy peer-to-peer trading system include:

[0024] The power supply subsystem has one active node a; the conversion subsystem has two active nodes: node b and node n; the transmission subsystem has one active node c; and the receiving terminal subsystem has one active node d. The states of active nodes a, b, and c are controlled by the entire system, the state of active node n is controlled by the receiving terminal subsystem, and the state of active node d is controlled by the supply terminal subsystem. It is also stipulated that:

[0025] The operating condition of the power supply subsystem is that node a is activated, i.e., a = 1;

[0026] The working condition of the conversion subsystem is that node c and node n are activated simultaneously, that is, b=1 and n=1;

[0027] The transmission subsystem operates when node b is activated, i.e., c = 1.

[0028] The working condition node d of the receiver's terminal subsystem is activated, i.e., d = 1;

[0029] Before the transaction, all nodes are inactive. After the transaction is completed, the supplier's terminal subsystem activates the target of the energy transfer: the receiver's terminal subsystem, and changes the activation node of the terminal subsystem to d=1. The integrated energy service system automatically activates node a of the energy supply subsystem and node b of the conversion subsystem. It waits for the receiver's terminal subsystem to update its payment ledger. When payment confirmation is received, the system activates node c of the transmission subsystem. The receiver's terminal subsystem selects the appropriate energy type in the conversion subsystem according to its needs and then activates node n. At this time, all subsystem nodes involved in energy transfer are activated, and each subsystem begins to work. The receiver's terminal subsystem receives the transferred energy.

[0030] Preferably, during the transaction process, when the supplier makes a recommendation or the receiver provides feedback, the feedback subsystem is used for: the supplier's terminal subsystem providing new energy service suggestions to the receiver's terminal subsystem through the feedback subsystem; the receiver's terminal subsystem providing service feedback and evaluation through the feedback subsystem; and both parties negotiating modifications to the transaction or terminating the transaction through the feedback subsystem.

[0031] Preferably, during the transaction process, when the energy provided by the supplier's terminal subsystem is the energy required by the receiver's terminal subsystem, the receiver's terminal subsystem does not need to activate node n of the conversion subsystem, and can directly transmit the energy to the receiver's terminal subsystem through the transmission subsystem.

[0032] (III) Beneficial Effects

[0033] This invention provides a blockchain-based integrated energy peer-to-peer trading system. Compared with existing technologies, it has the following advantages:

[0034] This invention provides a blockchain-based integrated energy peer-to-peer trading system, comprising: an energy supply subsystem, a terminal subsystem, and a regulation subsystem. The energy supply subsystem is used to input energy into the integrated energy service system; the terminal subsystem includes terminal subsystems for both suppliers and receivers, used to provide energy or receive and consume energy; the regulation subsystem deletes transaction information from other subsystem nodes after each transaction and records the transaction information in the regulation subsystem; the feedback subsystem assists the regulation subsystem in inquiring with both parties whether information deletion in the regulation subsystem is permitted. This invention utilizes the regulation subsystem for information storage management of the entire system, achieving unified integration of post-transaction information stored by each node, deleting redundant transaction information, reducing information storage pressure, and ensuring the stability of the peer-to-peer trading process.

[0037] Figure 2 This is a transaction flowchart of a blockchain-based peer-to-peer energy service transaction system according to an embodiment of the present invention. Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] This application provides a blockchain-based integrated energy peer-to-peer trading system, which solves the technical problem of excessive redundant information in existing blockchain-based integrated energy service systems. It achieves unified integration of information stored by each node after the transaction, reducing information storage pressure and improving the stability of the peer-to-peer trading process.

[0040] The technical solution in this application is to solve the above-mentioned technical problems, and the general idea is as follows:

[0041] Existing integrated energy service systems with peer-to-peer (P2P) transactions are still in the development, exploration, and pilot application stages, and have some shortcomings and areas for improvement. These shortcomings mainly include: 1. They only involve one-way transmission from the system to the terminal, lacking the ability for feedback from the terminal to the system, thus preventing bidirectional transmission and limiting transactions to the supplier's flow to the receiver. 2. In addition to the transaction information of each node (prosumer), each block on the blockchain also needs to store all the system's physical information, resulting in a significant increase in blockchain capacity and a decrease in performance. Node memory management also needs improvement. To address these issues, this invention proposes a blockchain-based integrated energy P2P transaction system. This system integrates the entire integrated energy service system more tightly using blockchain technology, providing a stable, reliable, and cost-effective production and consumption matching model for both supply and demand sides. Simultaneously, it utilizes smart contracts to provide both parties with an immutable distributed ledger, greatly reducing credit costs, promoting the release of more data from both parties, expanding the channels for data value circulation, and providing more value-added services for both service providers. Furthermore, both service providers can control the activation of various systems, with key systems requiring collaborative control to support real-time P2P transactions. Finally, a regulation subsystem is used to manage the information storage of the entire system, ensuring system performance and the stability of the peer-to-peer transaction process. The regulation and feedback subsystems address various situations that may arise during transactions.

[0042] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0043] This invention provides a blockchain-based integrated energy peer-to-peer trading system, comprising: an energy supply subsystem, a terminal subsystem, a regulation subsystem, and a feedback subsystem.

[0044] The energy supply subsystem is used to input energy into the integrated energy service system.

[0045] Terminal subsystems, including supplier and receiver terminal subsystems, are used to provide energy or receive and consume energy;

[0046] The adjustment subsystem is used to delete transaction information from all subsystem nodes after each transaction process and record the transaction information in the adjustment subsystem.

[0047] The feedback subsystem is used in conjunction with the adjustment subsystem to inquire with both parties to the transaction whether they can delete the transaction information recorded in the adjustment subsystem, that is, to completely delete the transaction information.

[0048] This invention utilizes a regulation subsystem to manage the information storage of the entire system, thereby enabling rational management of the information stored at each node after a transaction, deleting redundant transaction information, and ensuring system performance and the stability of the peer-to-peer transaction process.

[0049] It should be noted that, in specific embodiments, the present invention also includes a conversion subsystem and a transmission subsystem.

[0050] The aforementioned subsystems are equivalent to a single node or a collection of nodes, continuously distributed across the blockchain network. All subsystems serve the needs of the recipient; the feedback subsystem facilitates post-transaction information exchange between the two parties; and the regulation subsystem manages transaction information from other subsystems.

[0051] Each energy supplier's terminal subsystem or user can share all their energy data with all other users through the integrated energy service system. After a user submits an energy request, the blockchain transmits the request to the integrated energy service system via peer-to-peer transmission. The information of both parties is highly encrypted, and the service system can access the customer's request through a consensus mechanism. Other nodes (customers) cannot modify the transmitted data unless they control more than half of all data nodes, making information transmission relatively secure and preventing subjective, human-caused data alterations.

[0052] like Figure 1 As shown below, each subsystem is described in detail:

[0053] Energy supply subsystem:

[0054] Upon receiving a demand, the energy supply subsystem, as the first node in the entire system to transfer energy, begins supplying energy to the recipient. This subsystem only focuses on whether there is a demand, not the specific details of the demand. In other words, it begins working once activated.

[0055] Conversion subsystem:

[0056] The conversion subsystem converts the energy input from the power supply subsystem into the type of energy required by the terminal, according to the terminal's requirements.

[0057] Transmission subsystem:

[0058] The transmission subsystem enables energy output.

[0059] Terminal Subsystem:

[0060] The terminal subsystem includes both supplier and receiver terminal subsystems. The receiver's terminal subsystem is directly connected to the transmission node to consume energy. The supplier's terminal subsystem provides energy to the receiver's terminal subsystem through a service system. Throughout the process, energy is transferred unidirectionally, but the roles of the supplier's and receiver's terminal subsystems can be interchanged.

[0061] Feedback subsystem:

[0062] The feedback subsystem enables bidirectional communication between the receiver and the supplier. All requests made by either party, both initially and subsequently, are relayed back to the other through this subsystem. The supplier's terminal subsystem can proactively provide energy service suggestions to the receiver's terminal subsystem based on past customer needs, offering more personalized services; conversely, the receiver's terminal subsystem can also submit further feedback and requests.

[0063] Meanwhile, the feedback subsystem will assist the regulation subsystem in completing information management.

[0064] Regulation subsystem:

[0065] During a transaction, all system nodes record transaction information on their respective nodes. To prevent excessive information volume on each node, which could lead to increased blockchain capacity and performance degradation, the adjustment subsystem deletes all transaction-related content from all system nodes after each transaction and records it on its own subsystem. Similarly, communication between the parties in the feedback subsystem is also transferred to the adjustment subsystem, keeping the capacity of other subsystem nodes at their initial state and ensuring that node and blockchain performance does not degrade due to excessive memory usage. After each transaction, the adjustment subsystem queries both parties through the feedback subsystem to request permission to delete the transaction record on its own subsystem. If both parties agree, the transaction record is immediately deleted, permanently erasing the transaction information. If neither party agrees simultaneously, the transaction record is automatically deleted after the agreed-upon maximum destruction time, ensuring that the adjustment subsystem's memory does not become excessive. If one or both parties disagree with a transaction, they provide feedback through the feedback subsystem. Once both parties agree, the transaction ends, and the transaction information in those subsystems is deleted. The adjustment subsystem does not record this transaction information.

[0066] The transaction process of this system is as follows:

[0067] Before a transaction occurs, both parties agree on the terms and create a smart contract ledger. They jointly maintain a shared, interconnected ledger, reaching consensus on value confirmation, transactions, distribution, and the maximum expiration time. This creates an autonomous execution mechanism based on distributed ledger technology, effectively equating the blockchain with a smart contract. Blocks containing transactions are continuously added to the end of the chain in chronological order. To modify data in a block, all subsequent blocks must be regenerated. In commonly used file and relational databases, unless specially designed, the system itself does not record modification traces. The blockchain ledger uses a different design than files and databases, borrowing from real-world ledger designs—leaving a record of changes. Therefore, parties cannot "modify" the ledger without leaving a trace, but can only "correct" it, thus achieving the ledger's immutability.

[0068] Among the key features of this system's smart contract is the inclusion of a "maximum destruction duration" determination. This maximum destruction duration, agreed upon by both parties, determines how long the reconciliation subsystem retains numerous transaction records. Within this duration, both parties can use the transaction records on the reconciliation subsystem to determine liability or file complaints about violations. After the maximum destruction duration expires, the reconciliation subsystem will uniformly delete these transaction records, ensuring that its memory remains in a healthy state for better subsequent service delivery.

[0069] The power supply subsystem has one active node 'a' (the node has only two states: a=1 indicates active, a=0 indicates inactive. The states of nodes described below are similar); the conversion subsystem has two active nodes: node b and node n; the transmission subsystem has one active node c; and the receiving terminal subsystem has one active node 'd'. The states of active nodes a, b, and c are controlled by the entire system, the state of active node n is controlled by the receiving terminal subsystem, and the state of active node d is controlled by the supply terminal subsystem. It is also stipulated that:

[0070] The operating condition of the power supply subsystem is that node a is activated, i.e., a = 1;

[0071] The working condition of the conversion subsystem is that node c and node n are activated simultaneously, i.e., b = 1 and n = 1;

[0072] The transmission subsystem operates when node b is activated, i.e., c = 1.

[0073] The working condition node d of the receiver's terminal subsystem is activated, i.e., d = 1.

[0074] like Figure 2 As shown, the transaction process of this system includes: Before the transaction, all nodes are inactive. After the transaction is completed, the supplier's terminal subsystem activates the target of the energy transfer: the receiver's terminal subsystem, changing the activation node of the terminal subsystem to d=1; the integrated energy service system automatically activates node a of the energy supply subsystem and node b of the conversion subsystem; it waits for the receiver's terminal subsystem's payment ledger to be updated, and upon receiving payment confirmation, the system activates node c of the transmission subsystem; the receiver's terminal subsystem selects the appropriate energy type from the conversion subsystem according to its needs, and then activates node n. At this point, all subsystem nodes involved in energy transfer are active, each subsystem begins operation, and the receiver's terminal subsystem receives the transferred energy.

[0075] Similarly, when one party needs to provide feedback or recommendations, the supplier's terminal subsystem can provide the receiver's terminal subsystem with more energy service suggestions through the feedback subsystem; the receiver's terminal subsystem can also provide feedback and evaluation on the transaction through the feedback subsystem. At the same time, both parties can also use this subsystem to negotiate modifications to the transaction or to terminate it.

[0076] After the transaction is completed, the reconciliation subsystem will delete the transaction information of other subsystem nodes. The specific regulations for information management in the reconciliation subsystem are as follows:

[0077] 1. The transaction process is fully completed (both parties have no objections to the transaction):

[0078] The reconciliation subsystem deletes information about this transaction from other subsystems and records it only in this subsystem. At this point, only the reconciliation subsystem has recorded the transaction information. The reconciliation subsystem will then ask both parties to the transaction whether they allow the deletion of the transaction information on the reconciliation subsystem through the feedback subsystem. If both parties allow it, the transaction information on the reconciliation subsystem is deleted, i.e., the transaction information is permanently deleted; if neither party allows it simultaneously, the transaction information will remain on the reconciliation subsystem, and both parties can view and reference it. The reconciliation subsystem will delete the transaction information after the maximum agreed-upon destruction period has elapsed.

[0079] 2. If, during the transaction, both parties disagree and agree to modify or terminate the transaction:

[0080] The adjustment subsystem deletes information about this transaction from other subsystems, and the adjustment subsystem does not record this transaction information, thus ending the transaction.

[0081] The transaction process will be explained in detail below through two examples:

[0082] Example 1:

[0083] User B wants energy from Company A. Both parties reach an agreement and sign a smart contract. After the transaction occurs, the contract is executed, and value is transferred according to preset conditions. Upon receiving the automatic settlement result or updating its ledger from User B, Company A activates the corresponding terminal node based on the user's address.

[0084] Meanwhile, the integrated energy service system is also awaiting confirmation of funds from user B. B uses their private key to sign their fiat currency and transfers it to company A. If the assets involved are on-chain assets, settlement is completed automatically; if they are off-chain assets, the ledger is updated according to the off-chain settlement. The integrated energy service system first delivers company A's energy to the energy supply subsystem, which then transfers the energy to the conversion subsystem.

[0085] Next, user B selects the desired energy type and activates node n of the conversion subsystem. At this point, the transmission subsystem is also activated. The energy can then be converted into the type required by the user.

[0086] This allows for peer-to-peer transactions between companies and users to be completed on a blockchain-based integrated energy service system.

[0087] Example 2:

[0088] User A informs all other users on the blockchain that they have surplus of a certain type of energy. User B wants to acquire this energy from User A, and both parties reach an agreement and sign a smart contract. After the transaction occurs, the contract is executed, and the value is transferred according to preset conditions. When the transaction occurs, User A activates the corresponding terminal node based on User B's specific address. The integrated energy service system first delivers User A's energy to the energy supply subsystem.

[0089] Since this energy is the same energy required by user B, the conversion subsystem does not need to function and the energy is directly transferred to the transmission subsystem.

[0090] After the integrated energy service system receives confirmation of user B's funds account, it activates the transmission subsystem to transmit user A's energy to user B through the transmission subsystem.

[0091] This allows for peer-to-peer transactions between users to be completed on a blockchain-based integrated energy service system.

[0092] In Examples 1 and 2, if the receiving party's terminal subsystem has new energy needs or the supplier's terminal subsystem has new service recommendations, both parties can notify each other through the feedback subsystem. After both parties reach a new consensus, a new ledger is created and recorded on a new block. Then, the above transaction process is repeated.

[0093] If either party modifies or terminates the transaction, the feedback subsystem will notify the adjustment subsystem. The adjustment subsystem will then shut down other subsystems, and the transaction will end.

[0094] In summary, compared with existing technologies, it has the following beneficial effects:

[0095] 1. The entire system uses a regulating subsystem to delete and transfer transaction information, achieving rational management of post-transaction storage information across nodes, deleting redundant transaction information, and ensuring excellent system performance and stable peer-to-peer transactions. It will not experience performance degradation or crashes due to a surge in blockchain memory capacity. This further guarantees the completion of a large number of peer-to-peer transactions.

[0096] 2. The four key characteristics of blockchain technology can effectively address the shortcomings and drawbacks of traditional integrated energy services. It provides a safer and more flexible peer-to-peer trading platform for both parties. The activation of each node in the blockchain is controlled by different entities, and both parties collaborate to complete the entire transaction process, which is recorded in an immutable ledger, possessing the essential characteristics of interoperability, interconnectivity, and mutual trust.

[0097] 3. The supplier's terminal subsystem can provide better energy service suggestions to the receiver's terminal subsystem through the feedback subsystem, and the receiver's terminal subsystem can also provide transaction feedback and suggestions through this subsystem. Both parties can also modify or terminate the transaction.

[0098] It should be noted that in this technical solution, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0099] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
