[0020] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0021] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0022] The embodiment of the present application provides a method for constructing a power transaction settlement model based on a virtual power plant. The execution subject of the method for constructing a power transaction settlement model based on a virtual power plant includes but is not limited to at least one of the electronic devices such as a server and a terminal that can be configured to execute the method provided by the embodiment of the present application. In other words, the method for constructing a power transaction settlement model based on a virtual power plant can be executed by software or hardware installed on a terminal device or a server device, and the software can be a blockchain platform. The server includes but is not limited to: a single server, a server cluster, a cloud server or a cloud server cluster, etc.

[0023] Reference Figure 1 As shown, it is a flow chart of a method for constructing a power transaction settlement model based on a virtual power plant provided by an embodiment of the present invention. In this embodiment, the method for constructing a power transaction settlement model based on a virtual power plant includes: S1, receiving an energy query instruction, obtaining multiple distributed energy sources within a unit range according to the energy query instruction, and aggregating the multiple distributed energy sources, establishing a unified data acquisition system, energy management system and communication network, and obtaining a virtual power plant, wherein the distributed energy includes photovoltaic equipment, micro gas turbines and energy storage systems.

[0024] It is understandable that distributed energy refers to small-scale energy production units scattered in the power grid, close to the energy consumption end, which can work independently or collaboratively to meet local energy needs, and distributed energy both consumes energy and produces energy, playing the role of prosumers. In modern power systems, with the development of distributed energy technology, more and more electricity consumers have begun to have power generation capabilities, thus transforming into prosumers. When distributed energy acts as a prosumer, it can sell its own excess energy back to the grid or directly to other consumers, participate in energy market transactions, and provide grid services such as demand response and frequency regulation through distributed energy facilities to help maintain the stability of the grid.

[0025] It should be understood that a virtual power plant (VPP) is a new concept of power supply and management that integrates and optimizes the management of decentralized energy resources (including power generation, energy storage, and load) through software and intelligent technology to provide a coordinated power supply service. A virtual power plant is not a physical power plant, but a way of operating and managing a power grid that is achieved through digitalization and intelligent means.

[0026] Furthermore, virtual power plants can integrate various distributed energy resources, such as solar photovoltaics, micro gas turbines, energy storage systems, and demand-side management resources to form a unified and controllable energy supply network. Virtual power plants can also provide grid regulation services through energy storage systems and demand response, thereby enhancing the stability and reliability of the grid.

[0027] It can be understood that the unit scope can refer to a geographical area, indicating a specific geographical area or location, such as a city, community, industrial park, etc., within which distributed energy is deployed and managed, or it can be an organizational management scope, indicating distributed energy managed by a specific organization or institution. Although these energy sources may be distributed in different geographical locations, they all belong to the same management entity.

[0028] In an embodiment of the present invention, after the multiple distributed energy sources are aggregated to establish a unified data acquisition system, energy management system and communication network to obtain a virtual power plant, the method also includes: independently solving the power generation plan and power purchase and sales plan of each distributed energy source through a preset optimization objective, and sending the power purchase and sales plan and the initial electricity price point-to-point to other distributed energy sources in the virtual power plant; if the electricity obtained according to the power purchase and sales plan and the initial electricity price does not meet the power balance, the initial electricity price of the distributed energy source and the power generation plan are iteratively updated until the electricity obtained according to the power purchase and sales plan and the iteratively updated initial electricity price meets the power balance, thereby completing the point-to-point power transaction between the distributed energy sources.

[0029] Among them, the preset initial electricity price can be sent to each distributed energy in the virtual power plant through the virtual power plant, and the initial electricity price of each distributed energy can be exchanged in the virtual power plant through pre-built local communication.

[0030] Furthermore, the power balance formula of the distributed energy is: ,in, is the estimated upper limit of electricity sales of distributed energy h in the i-th virtual power plant in time period t, represents the daily load of distributed energy h in the i-th virtual power plant in time period t, is the energy storage of the distributed energy h in the i-th virtual power plant in time period t, is the micro gas turbine output of distributed energy h in the i-th virtual power plant in time period t; is the number of distributed energy resources in the i-th virtual power plant, is the power purchased by distributed energy h from distributed energy p in the i-th virtual power plant in time period t; is the actual photovoltaic output of distributed energy h in the i-th virtual power plant in time period t.

[0031] The specific contents of the optimization objectives include cost minimization, theoretical maximization, carbon emission minimization and other objectives, as well as constraints considered in the solution process, such as power generation capacity, grid stability, etc.

[0032] It is understandable that the power purchase and sales plan refers to a plan made by the business or operator of distributed energy to determine how much electricity they intend to purchase or sell within a specific period of time. The power purchase and sales plan is usually based on the following factors: power generation capacity, electricity demand, market conditions, energy storage status, contractual obligations, forecasts and scheduling, etc.

[0033] The market conditions refer to the fact that the owner will decide whether to sell excess electricity to obtain profits or purchase electricity when the electricity price is low based on the electricity price signal of the electricity market. The contractual obligations refer to the fact that the owner may need to fulfill the obligation to purchase or sell electricity according to the contract signed with the grid operator or other market participants.

[0034] It should be understood that peer-to-peer transactions between distributed energy resources in a virtual power plant can reduce losses during energy transmission, because electricity is traded directly between neighboring distributed energy resources, reducing the need for long-distance transmission. In addition, peer-to-peer electricity trading can better utilize distributed energy resources such as solar and wind energy, whose output is affected by weather and time, and local transactions can maximize their utilization efficiency.

[0035] S2. Obtain the operational requirements and specific requirements of the virtual power plant, select a blockchain type according to the operational requirements, obtain an initial blockchain, and adjust the initial blockchain according to the specific requirements of the virtual power plant to obtain a standard blockchain, wherein the operational requirements include energy trading, data management, security, compliance and grid stability, and the specific requirements include transaction speed, data privacy protection, complexity of smart contracts, cross-chain compatibility and energy metering.

[0036] Understandably, the Initial Blockchain is the starting point for building a blockchain solution, while the Standard Blockchain is the final product that has been customized and optimized to fully meet the needs of a virtual power plant.

[0037] It should be explained that the obtaining of the operational requirements and specific requirements of the virtual power plant, selecting a blockchain type according to the operational requirements to obtain an initial blockchain, and adjusting the initial blockchain according to the specific requirements of the virtual power plant to obtain a standard blockchain includes: collecting and analyzing the operational requirements of the virtual power plant, selecting a public chain, a consortium chain or a private chain according to the operational requirements, and deploying a blockchain platform to obtain an initial blockchain; adjusting the smart contract template in the initial blockchain, adjusting the consensus algorithm and optimizing the data storage structure according to the specific requirements of the virtual power plant to obtain a standard blockchain.

[0038] It should be understood that the types of blockchain include public chain, alliance chain and private chain. In the public chain, all nodes on the system can participate in the consensus process, but due to the large number of nodes participating in the consensus, the public chain will be inefficient; the nodes participating in the consensus process in the alliance chain are pre-selected internally; in the private chain, the consensus process is only executed by the central node, and the central node can determine the read permissions of other nodes.

[0039] Furthermore, consensus refers to the process of reaching agreement among multiple distributed energy resources in a virtual power plant. This process ensures that all participating distributed energy resources reach a unified understanding of the recording and status of data, even in the event that some distributed energy resources may fail or engage in malicious behavior. The consensus mechanism is a core component of the blockchain, ensuring the consistency and reliability of blockchain data.

[0040] It should be explained that operational requirements usually refer to the basic functional and performance requirements that virtual power plants need to meet in daily operations, and are key factors in ensuring that virtual power plants can operate smoothly and provide services; specific requirements focus more on the technical parameters and performance indicators that virtual power plants need to consider in particular when applying blockchain technology, and are usually directly related to the characteristics and capabilities of blockchain technology.

[0041] S3. Query the automation process required in the virtual power plant transaction, build transaction specifications according to the automation process, design contract logic based on the transaction specifications, and encode the contract logic through a preset blockchain language to obtain a transaction smart contract.

[0042] It is understandable that the automated processes required in the virtual power plant transactions refer to those transaction-related steps and operations that can be automatically executed through technical means, especially blockchain and smart contract technology. These processes are designed to improve transaction efficiency, reduce costs, enhance transparency, and reduce human errors.

[0043] Furthermore, the querying of the automated process required in the virtual power plant transaction and constructing the transaction specifications according to the automated process include: obtaining relevant transaction links by determining the links designed in the virtual power plant transaction, wherein the relevant transaction links include power generation, power metering, power trading, power settlement and certificate issuance; analyzing the relevant transaction links to obtain analysis results including improvement measures, and designing an automated transaction process based on the analysis results, and constructing transaction specifications according to the automated process.

[0044] It should be understood that the contract logic refers to a series of rules and operating procedures defined in the smart contract, which are used to automatically execute and manage energy transactions in the virtual power plant. The smart contract refers to a program running on the blockchain that can automatically execute the contract terms when the preset conditions are met.

[0045] Among them, contract logic may include key elements such as transaction conditions, identity authentication, measurement and verification, payment processing, compliance checks, data recording, etc.

[0046] Furthermore, the contract logic is designed through the transaction specification, and the contract logic is encoded through a preset blockchain language to obtain a transaction smart contract, including: defining state variables, functions, events and permission controls in the transaction according to the transaction specification, and designing the logical flow of the transaction contract to obtain the contract logic; obtaining the smart contract code by selecting a suitable blockchain language and encoding the contract logic into a code form; performing unit testing and integration testing on the smart contract code in a test network or sandbox environment, and obtaining the transaction smart contract when the unit test and integration test pass.

[0047] It is understandable that by querying the automated processes required in virtual power plant transactions, building transaction specifications, designing contract logic, and encoding them into transaction smart contracts, this process realizes the automation and intelligent management of energy transactions in virtual power plants, which not only improves transaction efficiency and reduces costs, but also enhances transaction transparency and security, ensures transaction compliance and grid stability, and provides a reliable and efficient trading platform for virtual power plants, enabling them to better respond to market changes and user needs.

[0048] S4. Deploy the transaction smart contract to the standard blockchain, construct an initial transaction settlement model, optimize the standard blockchain and the transaction smart contract to obtain an optimization result, adjust the initial transaction settlement model according to the optimization result, and obtain a standard transaction settlement model.

[0049] It should be explained that the optimization of the standard blockchain and the transaction smart contract to obtain the optimization results includes: determining the key performance indicators that need to be optimized by evaluating the performance of the standard blockchain combined with the transaction smart contract, wherein the key performance indicators include transaction processing speed, network throughput, security, data privacy protection and energy metering accuracy; analyzing the current status of the standard blockchain and the transaction smart contract, and analyzing according to the key performance indicators that need to be optimized to obtain analysis results; designing a targeted optimization plan based on the analysis results to optimize the standard blockchain and the transaction smart contract to obtain optimization results, wherein the optimization plan includes improving the smart contract code, optimizing the blockchain consensus mechanism, and enhancing data privacy protection measures.

[0050] It is understandable that by deploying transaction smart contracts to the standard blockchain and building and optimizing the initial transaction settlement model, this process realizes the automation, security improvement, performance optimization and compliance guarantee of electricity trading, and ultimately forms an efficient, stable and flexible standard transaction settlement model, providing virtual power plants with strong market competitiveness and continuous improvement capabilities.

[0051] S5. Obtain the identity information of the owner of the distributed energy connected to the virtual power plant, perform identity authentication and energy authentication on the business of the distributed energy according to the identity information, and perform transaction matching based on the standard transaction settlement model when the identity authentication and energy authentication are passed to obtain a matching result.

[0052] It should be understood that by verifying the owner's identity and the authenticity of energy information, only certified distributed energy can participate in transaction matching based on the standard transaction settlement model, thereby ensuring the legitimacy of the transaction, enhancing market trust, and promoting efficient and reliable energy transactions.

[0053] Furthermore, the identity information refers to the process of verifying the legitimacy and authenticity of the identity of individuals or enterprises that manage and control distributed energy, which usually involves relevant identity documents, business licenses and other official documents to ensure that the distributed energy owners participating in the transaction are authorized and trustworthy; the energy certification refers to a series of verifications and assessments of the technical parameters, production capacity, safety and compliance of distributed energy facilities to ensure that these facilities can provide energy in accordance with established standards and regulations, thereby ensuring the quality and reliability of energy supply.

[0054] S6. The multilateral bidding transaction mechanism proposed by the rules of the virtual power plant is used to eliminate the electric energy deviation in the matching result, and to carry out power trading and power transmission to realize power settlement.

[0055] It should be explained that the Multi-sided Auction Mechanism refers to a market mechanism in which multiple buyers and sellers determine the price and quantity of power transactions through bidding in the power market. This mechanism allows multiple buyers (power consumers) and sellers (power producers) to submit their buy and sell orders at the same time, and a centralized trading platform is used to match the orders of buyers and sellers, and finally determine the price and quantity of the transaction.

[0056] It is understandable that the multilateral bidding transaction mechanism proposed through the rules of the virtual power plant eliminates the electric energy deviation in the matching result, and conducts electric energy trading and electric energy transmission to realize electric energy settlement, including: monitoring the electric energy supply and demand deviation between the distributed energy sources within the virtual power plant to obtain the internal supply and demand deviation; obtaining the electric energy quotations of each distributed energy in the virtual power plant to obtain multiple electric energy quotations; sorting the multiple electric energy quotations according to the rules of the virtual power plant to obtain an electric energy quotation ranking, and adjusting the matching result according to the electric energy quotation ranking and the internal supply and demand deviation to obtain an adjusted transaction result; conducting electric energy trading and electric energy transmission according to the adjusted transaction result to realize electric energy settlement.

[0057] Furthermore, the electricity supply and demand deviation refers to the difference between the actual power supply in the power system and the user demand. This deviation may be caused by factors such as inaccurate forecasts, volatility of renewable energy, equipment failure or load changes, and has an important impact on the stability of the power grid and the operation of the power market.

[0058] It is understandable that the matching results are adjusted to obtain the adjusted transaction results based on the supply and demand deviation and quotation ranking, and an adjustment strategy is formulated to achieve dynamic balance of electricity supply and demand and optimize the allocation of electricity resources. For example, if there is an oversupply of electricity in a certain period of time, sellers with lower prices may be given priority; if there is insufficient power supply, it may be necessary to find additional electricity supply at a reasonable price.

[0059] It should be understood that by monitoring and adjusting the deviation between electricity supply and demand of distributed energy within the virtual power plant, optimizing the ranking of electricity quotations, and executing electricity transactions and settlements based on the adjusted transaction results, it is possible to achieve supply and demand balance, improve transaction efficiency and grid stability, and ensure the effective operation of the electricity market. Among them, optimizing the ranking of electricity quotations can be to introduce distance parameters, stability parameters, etc. into the basic high to low electricity price ranking, and recalculate and sort the electricity prices.

[0060] Furthermore, the method further comprises: counting the real-time supply and demand deviation of the virtual power plant, and dividing each virtual power plant into a bidding virtual power plant participating in the bidding and a purchasing virtual power plant to purchase electricity according to the electric energy of the virtual power plant, obtaining the bidding quotations of the bidding virtual power plant and the required electric energy of the purchasing virtual power plant; sealing and sorting the bidding quotations of the bidding virtual power plant, and encrypting the bidding quotations using a hash function to obtain encrypted quotations; reporting the required electric energy of the purchasing virtual power plant to the trading platform, and after counting the total demand electric energy, the trading platform matches the real-time supply and demand deviation of the virtual power plant and the encrypted quotations to obtain the matching transaction price and share, and returns the matching transaction price and share to the bidding virtual power plant; notifying the bidding virtual power plant to complete the point-to-point energy clearing according to the matching transaction price and share.

[0061] Among them, sealed sorting means that during the bidding process in the electricity market, the quotations submitted by the bidding virtual power plants will be confidentially sorted, and these quotations will be encrypted using hash functions to ensure the privacy and security of the quotations until the final transaction results are announced, thereby ensuring the fairness and transparency of the bidding process.

[0062] It should be understood that by real-time monitoring of the supply and demand deviation of virtual power plants, dividing virtual power plants into bidders and electricity buyers, and encrypting the bidders' quotations, the security and privacy of transactions can be ensured. The trading platform matches the supply and demand deviation with the encrypted quotations, determines the transaction price and share, and then guides the bidding virtual power plants to complete point-to-point energy clearing, which can achieve efficient allocation of power resources, improve the transparency and security of the power market, and optimize the configuration of power resources.

[0063] In order to solve the problems described in the background technology, the present invention receives an energy query instruction, obtains multiple distributed energy sources within a unit range according to the energy query instruction, and aggregates the multiple distributed energy sources to establish a unified data acquisition system, energy management system and communication network to obtain a virtual power plant, wherein the distributed energy includes photovoltaic equipment, micro gas turbines and energy storage systems. It can be seen that the present invention integrates the distributed energy located in the underlying structure of the system to form a virtual power plant for unified and standardized management. The present invention obtains the operational requirements and specific requirements of the virtual power plant, and selects a blockchain type according to the operational requirements to obtain an initial blockchain, and adjusts the initial blockchain according to the specific requirements of the virtual power plant to obtain a standard blockchain.
