Description

Technical Field

[0001] The present invention relates to the field of electric power technology, and in particular to a control method, device and equipment for aggregate electric vehicles to participate in peak load regulation. Background Art

[0002] In recent years, with the popularity of electric vehicles, as adjustable loads, the potential of electric vehicles to participate in grid peak load regulation has not been fully utilized. At present, the aggregation of electric vehicles to participate in peak load regulation is a method to participate in grid peak load regulation more efficiently by centrally managing and coordinating the battery storage capacity of many electric vehicles. This method can improve the efficiency of electric vehicles as grid peak load regulation resources and reduce dependence on a single electric vehicle. However, the existing grid peak load regulation method mainly uses a centralized system to process data from many electric vehicles. In actual applications, when many electric vehicle users operate in real time, the system needs to process large-scale data traffic. The data processing and data management processes of the centralized system are relatively complicated, and it is difficult to effectively verify the authenticity and integrity of each piece of data, resulting in low system processing efficiency and inability to guarantee the credibility of the data. Summary of the invention

[0003] The present invention provides a control method for aggregating electric vehicles to participate in peak load regulation, so as to solve the technical problems of low processing efficiency of the system and failure to ensure the credibility of data.

[0004] In order to solve the above technical problems, an embodiment of the present invention provides a control method for aggregating electric vehicles to participate in peak load regulation, the method comprising:

[0005] After obtaining the user declaration data of the electric vehicle user, the user's willingness to participate in peak-shaving and the real-time peak-shaving demand of the power grid respectively, it is identified whether the user's willingness to participate in peak-shaving is to agree to participate in peak-shaving, and it is judged whether the user declaration data meets the constraints pre-set in the blockchain platform, wherein the user declaration data and the user's willingness to participate in peak-shaving are collected after issuing a peak-shaving invitation, and the peak-shaving invitation includes: the peak-shaving consumption period, the total consumption power required by the power grid for electric vehicles to consume and the subsidy price, and the user declaration data includes: the declared power that can be consumed during the consumption period, the original consumption power and the user's quotation;

[0006] If the electric vehicle user is willing to agree to participate in peak load regulation and the user-declared data meets the constraint conditions, determine whether the grid peak load regulation demand is consistent with the total declared power provided by all the user-declared data. If so, generate a peak load regulation decision based on the grid peak load regulation demand and the user-declared data, wherein the peak load regulation decision includes: a list of electric vehicle users participating in peak load regulation, the declared power volume of each electric vehicle user and the user quotation. Specifically, the peak load regulation decision is generated by distributing and storing the grid peak load regulation demand, the subsidy price, the constraint conditions and the user-declared data on multiple nodes of the blockchain platform, and matching them after reaching a consensus of at least two-thirds of the nodes;

[0007] A peak-shaving task for each electric vehicle is generated according to the peak-shaving decision, a subsidy settlement amount for each electric vehicle user is calculated and paid according to the peak-shaving task, the subsidy settlement amount is recorded on the blockchain platform and a settlement report is provided, wherein the peak-shaving task includes the actual charging or discharging amount consumed or provided and the user's quotation.

[0008] Furthermore, the peak-shaving demand of the power grid and the user-declared data are matched with the peak-shaving decision through a transaction matching function, and the transaction matching function takes maximizing the profit as the objective function, and the objective function is:

[0009]

[0010] Among them, i=1,2,3 is the number of electric vehicle users participating in peak load regulation, ΔW i =W i -W i , , which means that electric vehicle users commit to charging capacity outside the plan in response to grid consumption, W i W is the reported amount of electricity that can be consumed during the consumption period, i , is the original power consumption, P average is the subsidy price, P i Provide quotes to users.

[0011] Furthermore, the constraints include: peak-shaving price constraints, peak-shaving capacity constraints and peak-shaving demand constraints. If the electric vehicle user is willing to participate in peak-shaving and satisfies three of the constraints at the same time, he / she participates in peak-shaving; otherwise, he / she exits peak-shaving.

[0012] Furthermore, the calculation formula for the subsidy settlement amount is:

[0013]

[0014] Where i=1, 2, 3 is the number of electric vehicle users participating in peak load regulation, Wactual,i is the actual amount of electricity consumed or provided, P i Provide quotes to users.

[0020] The peak-shaving willingness smart contract module is used to determine whether the grid peak-shaving demand is consistent with the total declared power provided by all the user declared data if the electric vehicle user is willing to agree to participate in the peak-shaving and the user declared data meets the constraint conditions. If so, a peak-shaving decision is generated according to the grid peak-shaving demand and the user declared data, wherein the peak-shaving decision includes: a list of electric vehicle users participating in the peak-shaving, the declared power of each electric vehicle user and the user quotation. The peak-shaving decision is generated specifically by storing the grid peak-shaving demand, the subsidy price, the constraint conditions and the user declared data in multiple nodes of the blockchain platform in a dispersed manner, and matching them after consensus of at least two-thirds of the nodes;

[0023]

[0024] Among them, i=1,2,3 is the number of electric vehicle users participating in peak load regulation, ΔW i =W i -W i , , which means that electric vehicle users commit to charging capacity outside the plan in response to grid consumption, W i W is the reported amount of electricity that can be consumed during the consumption period, i , is the original power consumption, P average is the subsidy price, P i Provide quotes to users.

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] Specifically, blockchain is a decentralized distributed ledger that is stored in a block chain, cannot be tampered with, is secure and reliable, and records transactions and information through a continuously growing data block chain to ensure data security and transparency.

[0050] Specifically, a smart contract is a computer program that automatically executes, controls or documents legal events and actions. Smart contracts automatically execute contract terms when preset conditions are met. The invention can be done without a third-party intermediary, and the execution process is traceable and irreversible. Today's smart contracts are usually directly bound to the blockchain and run on the blockchain. The computer program ensures the transparency, immutability and decentralization of the contract terms. This automation and decentralization make smart contracts an important part of decentralized applications.

[0051] Specifically, the aggregator is a load aggregator, which is registered through the demand response management platform and is one of the entities participating in the demand side response. The entities participating in the demand side response include large electricity users, load aggregators and virtual power plants. More specifically, charging pile operators are natural load aggregators.

[0052] Specifically, electric vehicle aggregation refers to integrating the charging and discharging behaviors of many electric vehicles through controllable load aggregators to participate in grid regulation as a unified power resource.

[0053] Specifically, peak shaving refers to the process of adjusting power generation or load to balance the supply and demand of the power grid.

[0054] Due to the rapid development of new energy vehicles, it is even more necessary to allow many electric vehicle users to participate in the peak load regulation of the power grid to improve the efficiency of electric vehicles as a peak load regulation resource of the power grid and reduce the rate of wind and solar power abandonment. At present, the centralized system of centralized management has the problem of slow data processing efficiency and the need to rely on third-party intermediaries for calculations, resulting in an opaque calculation process, which makes it impossible for electric vehicle users to maintain confidence in it, thereby reducing the participation rate of electric vehicle users.

[0055] The blockchain platform of the present invention integrates an acquisition module, a peak-shaving intention smart contract module and a clearing smart contract module, so that the entire process of aggregated electric vehicles participating in peak-shaving is automatically executed through smart contracts, thereby improving the efficiency and response speed of electric vehicles participating in power grid peak-shaving, thereby increasing the participation rate of electric vehicle users. At the same time, the present invention refers to the smart contract that introduces blockchain technology, which ensures the accuracy of electricity data without the intervention of a third-party intermediary. Based on the traceable, irreversible and tamper-proof characteristics of the blockchain platform, the credibility and transparency of the aggregated electric vehicles participating in the peak-shaving process are guaranteed.

[0056] The present invention can also use aggregators as third-party intermediaries. Aggregators can play a role in zoning management, improve work efficiency, and make it easier for electric vehicle users who are willing to participate in peak-shaving to receive peak-shaving invitations. Due to the introduction of smart contracts based on blockchain technology, aggregators can be prevented from privately tampering with electric vehicle users' peak-shaving participation willingness, user-declared data, and power grid peak-shaving demands issued by the power dispatching center without the consent of the power dispatching center and the electric vehicle users. This can also improve the credibility of the peak-shaving process in which aggregated electric vehicles participate and ensure the transparency of data processing.

[0057] Embodiment 1

[0058] Please refer to Figure 1 and Figure 4 , a control method for aggregating electric vehicles to participate in peak load regulation is provided in an embodiment of the present invention, and the control method includes:

[0059] Step S10: After respectively obtaining the user declaration data of the electric vehicle user, the user's willingness to participate in peak-shaving and the real-time peak-shaving demand of the power grid, identify whether the user's willingness to participate in peak-shaving is to agree to participate in peak-shaving, and judge whether the user declaration data meets the constraints pre-set in the blockchain platform, wherein the user declaration data and the user's willingness to participate in peak-shaving are collected after issuing a peak-shaving invitation, and the peak-shaving invitation includes: the peak-shaving consumption period, the total consumption power that the power grid needs to consume by electric vehicles, and the subsidy price, and the user declaration data includes: the declared power that can be consumed during the consumption period, the original consumption power, and the user's quotation.

[0060] Specifically, the peak-shaving demand of the power grid includes the total amount of electricity that the power grid needs electric vehicles to consume in the same period in history and the subsidy price corresponding to each period in history. The real-time peak-shaving demand of the power grid is the total amount of electricity that the power grid needs electric vehicles to consume in the current period in history according to the query of the current period.

[0061] Specifically, the total amount of electricity that the power grid needs to consume by electric vehicles in the same period of history can be downloaded from the power company's website, and the subsidy price corresponding to each period of history can be found from the pricing strategy of the power market, and the pricing strategy is formulated uniformly by the power market.

[0062] In this embodiment, obtaining the total amount of electricity that the electric vehicle needs to consume during the current period of the power grid can ensure the accuracy of the acquired data information, and based on the accurate data information, the specific peak load operation can be optimized in real time. In addition, the available energy storage of the electric vehicle can be obtained, and the battery status of the electric vehicle can be detected to optimize the peak load operation.

[0063] In this embodiment, electric vehicle users interact with the power dispatch center through the blockchain platform. When peak load regulation is required, the power dispatch center will send a peak load regulation instruction to the blockchain platform. Aggregators receive the peak load regulation instruction through the blockchain platform and learn about the peak load regulation demand of the power dispatch center. Electric vehicle users publish their willingness to participate in peak load regulation and user declaration data to the blockchain platform.

[0064] In another optional embodiment of the present invention, the electric vehicle users of this embodiment interact with the aggregators through the blockchain platform, and the aggregators interact with the power dispatching center through the blockchain platform. When peak shaving is required, the power dispatching center will send a peak shaving instruction to the blockchain platform. The aggregators receive the peak shaving instruction through the blockchain platform and learn about the power grid peak shaving demand of the power dispatching center. The aggregators issue peak shaving invitations and collect peak shaving participation willingness and user declaration data.

[0065] The control method of the present invention is applied to a blockchain platform, which is usually bound to a smart contract. The blockchain platform automatically performs various operations according to a preset smart contract. The smart contract can send a form to the electric vehicle user, which includes a form for the electric vehicle user's willingness to participate in peak load regulation and a form for user declaration data.

[0066] In this embodiment, the peak-shaving invitation can be sent directly to the electric vehicle user; the peak-shaving invitation can also be sent to the aggregator. After receiving the peak-shaving demand and peak-shaving invitation issued by the power grid, the aggregator issues the peak-shaving invitation to the electric vehicle user. The electric vehicle user can view the peak-shaving invitation and fill in the willingness to participate in the peak-shaving and the user declaration data according to the provided form.

[0067] Aggregators can play a role in zoning management, improve work efficiency, and make it easier for electric vehicle users who are willing to participate in peak-shaving to receive peak-shaving invitations. The introduction of smart contracts based on blockchain technology can prevent aggregators from privately tampering with electric vehicle users' peak-shaving participation willingness, user-declared data, and grid peak-shaving demands issued by the power dispatching center without the consent of the power dispatching center and electric vehicle users.

[0068] Specifically, the constraints are written into the smart contract of the blockchain platform in advance. After collecting the user-declared data, the smart contract automatically begins to identify whether the user-declared data meets the constraints.

[0069] Step S20: If the electric vehicle user is willing to agree to participate in peak-shaving and the user-declared data meets the constraints, determine whether the grid peak-shaving demand is consistent with the total declared power provided by all the user-declared data; if so, generate a peak-shaving decision based on the grid peak-shaving demand and the user-declared data, wherein the peak-shaving decision includes: a list of electric vehicle users participating in peak-shaving, the declared power of each electric vehicle user and the user's quotation; generating a peak-shaving decision specifically involves distributing and storing the grid peak-shaving demand, the subsidy price, the constraints and the user-declared data on multiple nodes of the blockchain platform, and matching them after consensus is reached by at least two-thirds of the nodes.

[0070] In this embodiment, the step of identifying the willingness of electric vehicle users to participate in peak load regulation and the step of determining whether the user-declared data meets the constraint conditions can be executed in parallel through parallel instructions, thereby shortening the calculation time.

[0071] Specifically, analyzing whether the peak-shaving demand of the power grid is consistent with the total reported electricity provided by all users' declared data is to determine whether the peak-shaving demand of the power grid and the total reported electricity meet the supply and demand balance. If they meet the requirements, matching peak-shaving decisions are made to ensure that the electricity is consumed in sufficient quantities, to ensure the supply and demand balance, and to reduce the wind and solar power abandonment rates.

[0072] Step S30: generating a peak-shaving task for each electric vehicle according to the peak-shaving decision, calculating and paying a subsidy settlement amount for each electric vehicle user according to the peak-shaving task, recording the subsidy settlement amount on the blockchain platform and providing a settlement report, wherein the peak-shaving task includes the actual amount of charging or discharging consumed or provided and the user's quotation.

[0073] The price clearing operation can be performed according to the peak-shaving decision, and then the peak-shaving task of each electric vehicle can be generated based on the price clearing operation. Finally, the subsidy settlement amount of each electric vehicle user is calculated and paid according to the peak-shaving task, and the subsidy settlement amount is recorded on the blockchain platform and a settlement report is provided, wherein the peak-shaving task includes the actual amount of charging or discharging consumed or provided and the user's quotation. In this embodiment, the smart contract responds to the procedure of the price clearing operation to perform the price clearing operation, and responds to the procedure of allocating the peak-shaving task after completing the price clearing operation. The aggregator performs charging or discharging on the electric vehicle according to the peak-shaving task assigned to each charging pile, and calculates the subsidy settlement amount according to the peak-shaving task after completing the peak-shaving task, and pays the subsidy settlement amount to the electric vehicle user. For fairness and transparency, the subsidy settlement amount is recorded on the blockchain platform, and settlement reports are provided for power companies, aggregators, and electric vehicle users respectively.

[0074] Specifically, the price clearing operation may be performed to determine the final electricity distribution and price, that is, the actual amount of charging or discharging consumed or provided and the user's quotation.

[0075] In the present invention, the data of each node of the aggregated electric vehicles participating in the entire process of peak-shaving are stored on the blockchain platform to record the data information of each node for aggregators and electric vehicle users to view. Due to the characteristics of the blockchain platform, the uploaded data cannot be modified, making the entire peak-shaving process transparent, reflecting the transparency and authenticity of the entire peak-shaving process, improving the credibility of electric vehicle users, and thus increasing the willingness of electric vehicles to participate in cooperation.

[0076] Specifically, the data information of each node includes the collected electric vehicle users' willingness to participate in peak-shaving, user declaration data, price clearing operations, execution operations of peak-shaving tasks, and subsidy settlement amounts.

[0077] In the embodiment of the present invention, the smart contract mechanism of the blockchain platform is used to automatically execute the whole process of the aggregated electric vehicles participating in the peak load regulation through the smart contract, thereby improving the efficiency and response speed of the electric vehicles participating in the peak load regulation of the power grid. At the same time, the present invention can ensure the accuracy of the power data without the intervention of a third-party intermediary. Based on the traceable, irreversible and tamper-proof characteristics of the blockchain platform, it can ensure that the data uploaded to the blockchain is accurate and true and cannot be tampered with, thereby improving the credibility of the aggregated electric vehicles participating in the peak load regulation process and ensuring the transparency of data processing.

[0078] The present invention can also use aggregators as third-party intermediaries. Aggregators can play a role in zoning management, improve work efficiency, and make it easier for electric vehicle users who are willing to participate in peak-shaving to receive peak-shaving invitations. Due to the introduction of smart contracts based on blockchain technology, aggregators can be prevented from privately tampering with electric vehicle users' peak-shaving participation willingness, user-declared data, and power grid peak-shaving demands issued by the power dispatching center without the consent of the power dispatching center and the electric vehicle users. This can also improve the credibility of the peak-shaving process in which aggregated electric vehicles participate and ensure the transparency of data processing.

[0079] like Figure 4 As shown, an embodiment of the present invention further provides a device for aggregating electric vehicles to participate in peak load regulation, and the device for aggregating electric vehicles to participate in peak load regulation is used to implement a control method for aggregating electric vehicles to participate in peak load regulation, and the device includes:

[0080] The acquisition module is used to respectively obtain the user declaration data of the electric vehicle user, the user's willingness to participate in peak-shaving and the real-time peak-shaving demand of the power grid, identify whether the user's willingness to participate in peak-shaving is to agree to participate in peak-shaving, and judge whether the user declaration data meets the constraints pre-set in the blockchain platform, wherein the user declaration data and the user's willingness to participate in peak-shaving are collected after issuing a peak-shaving invitation, the peak-shaving invitation includes: the peak-shaving consumption period, the total consumption power that the power grid needs to consume by electric vehicles and the subsidy price, and the user declaration data includes: the declared power that can be consumed during the consumption period, the original consumption power and the user's quotation.

[0081] The peak-shaving willingness smart contract module is used to determine whether the grid peak-shaving demand is consistent with the total declared electricity provided by all the user declared data if the electric vehicle user is willing to agree to participate in peak-shaving and the user declared data meets the constraints. If so, a peak-shaving decision is generated based on the grid peak-shaving demand and the user declared data, wherein the peak-shaving decision includes: a list of electric vehicle users participating in peak-shaving, the declared electricity of each electric vehicle user and the user's quotation. The peak-shaving decision is generated specifically by storing the grid peak-shaving demand, the subsidy price, the constraints and the user declared data in a dispersed manner on multiple nodes of the blockchain platform, and matching them after consensus is reached by at least two-thirds of the nodes.

[0082] In this embodiment, the peak-shaving willingness smart contract module interacts with the electric vehicle user, and a program is set in the peak-shaving willingness smart contract module, and a form for filling in the electric vehicle user's willingness to participate in peak-shaving and the user's declared data is popped up on the electric vehicle user's operation interface. After the form is filled in, the peak-shaving participation willingness and the user's declared data are stored on the blockchain platform through the smart contract. After identifying that the user's declared data meets the constraint conditions, the electric vehicle user's willingness to participate in peak-shaving is obtained at the same time, and the smart contract automatically matches the corresponding peak-shaving decision based on the aggregator's total power demand and the user's declared data.

[0083] In this implementation, the peak-shaving willingness smart contract module automatically executes the above procedures through the smart contract mechanism, improving the interactive experience of electric vehicle users.

[0084] The clearing smart contract module is used to generate a peak-shaving task for each electric vehicle according to the peak-shaving decision, calculate and pay the subsidy settlement amount for each electric vehicle user according to the peak-shaving task, record the subsidy settlement amount on the blockchain platform and provide a settlement report, wherein the peak-shaving task includes the actual charging or discharging amount consumed or provided and the user's quotation.

[0085] In an embodiment of the present invention, an acquisition module, a peak-shaving intention smart contract module and a clearing smart contract module are integrated on the blockchain platform, so that the entire process of aggregated electric vehicles participating in peak-shaving is fully automatically executed through smart contracts.

[0086] The beneficial effects of the device for the participation of aggregated electric vehicles in peak load regulation according to the embodiment of the present invention are equivalent to the beneficial effects of the control method for the participation of aggregated electric vehicles in peak load regulation described above, and will not be elaborated here.

[0087] In this embodiment, the blockchain platform uses the smart contract mechanism to upload the data information of each node when each module executes its function to the blockchain platform. When one module needs to obtain data from another module, it obtains it from the blockchain platform through the smart contract in the module.

[0088] Embodiment 2

[0089] Please refer to Figure 2 Based on the first embodiment, the specific steps of step S20 of the present invention include:

[0090] Step S21, the smart contract determines whether the electric vehicle user is a new user;

[0091] If the electric vehicle user is a new user, a registration information form is provided to the new electric vehicle user. The new electric vehicle user joins the smart contract by filling out the registration form. The smart contract verifies whether the registration information form is complete and valid. If so, the new electric vehicle user is added to the database of the blockchain platform and a unique identifier is created for the new electric vehicle user. The registration information form includes the electric vehicle user ID, contact information, electric vehicle model, battery specifications and user charging preferences.

[0092] Specifically, a registration information form is provided for new users to fill out. The blockchain platform can verify whether the registration information form is complete and valid through the smart contract. More specifically, corresponding verification instructions can be stored in the smart contract in advance, and verification is performed through the verification instructions. In a specific embodiment, the electric vehicle user identification can be a license plate, and the contact information can be a telephone number. Rules such as whether the license plate is 5 digits and whether the telephone number is 11 digits are established to verify whether the information is complete and valid.

[0093] In this embodiment, after the registration information form verification is completed, the process automatically jumps to step S22.

[0094] If the electric vehicle user is not a new user, the process automatically jumps to step S22 and logs into the blockchain platform to provide the smart contract with the willingness to participate in peak load regulation and user declaration data.

[0095] Step S22: The aggregator issues a peak-shaving invitation, which includes the consumption period of this peak-shaving, the total consumption power that the power grid needs electric vehicles to consume, and the subsidy price.

[0096] Step S23: Electric vehicle users log in to the blockchain platform to collect the electric vehicle users' willingness to participate in peak load regulation and the user declaration data provided to the aggregator.

[0097] Specifically, a quotation form for collecting user-declared data is popped up on the operation interface of the electric vehicle user, and the electric vehicle user fills in the quotation form to provide the user-declared data to the aggregator.

[0098] Specifically, the data on the original amount of electricity consumed will be recorded on the blockchain platform, allowing electric vehicle users to view historical data and aggregators to analyze the battery status of electric vehicles.

[0099] More specifically, aggregators can also obtain information about user charging preferences and battery status to dynamically adjust peak-shaving participation strategies to provide personalized services that match personalized data suitable for the charging or discharging amount of the electric vehicle.

[0100] Step S24: Identify whether the electric vehicle user is willing to participate in peak load regulation and determine whether the user's declared data meets the constraints pre-set in the blockchain platform.

[0101] If both conditions are met, peak load regulation starts; otherwise, peak load regulation is exited.

[0102] The peak load willingness smart contract module of the present invention may include:

[0103] The user registration submodule has a user registration function, and the smart contract determines whether the electric vehicle user is a new user;

[0104] If so, a registration information form is provided to the new electric vehicle user through the user registration function. The new electric vehicle user joins the smart contract by filling out the registration form. The smart contract verifies whether the registration information form is complete and valid. If so, the new electric vehicle user is added to the database of the blockchain platform and a unique identifier is created for the new electric vehicle user. The registration information form includes the electric vehicle user ID, contact information, electric vehicle model, battery specifications, and user charging preferences.

[0105] If not, the user login function is executed to log in directly to the blockchain platform to provide the smart contract with the willingness to participate in peak load regulation and user declaration data.

[0106] Specifically, the user login submodule interacts with the electric vehicle user through the user registration function, and determines through the smart contract whether the information input by the electric vehicle user corresponds to the unique identifier stored in the blockchain platform. If so, the user login function is executed; if not, the user registration function is executed.

[0107] The user login submodule has a user login function. Electric vehicle users log in to the blockchain platform through the user login function. The user login function is used to collect the willingness of electric vehicle users to participate in peak load regulation and the user declaration data provided to the aggregator.

[0108] Specifically, the user login function can provide the electric vehicle user with an operation process of the login program. The electric vehicle user logs in to the blockchain platform through the user login function, and the user login function can respond to the form program for filling in the user's declared data.

[0109] The peak-shaving invitation submodule has a peak-shaving invitation function. According to the peak-shaving invitation function, the aggregator publishes the peak-shaving invitation. The peak-shaving invitation includes the consumption period of this peak-shaving, the total consumption power that the power grid needs electric vehicles to consume, and the subsidy price.

[0110] The user quotation submodule has a user quotation function, which collects user declaration data provided by electric vehicle users to aggregators. The user declaration data includes the declared electricity that can be consumed during the consumption period and the user quotation.

[0111] Specifically, the user quotation function interacts with the electric vehicle user, and the aggregator sends a program for providing declared power and user quotation to the electric vehicle user through the user quotation function. After the user quotation function receives the peak-shaving invitation, a quotation form for collecting user declared data pops up on the operation interface of the electric vehicle user, and the electric vehicle user starts to provide the user declared data to the aggregator online.

[0112] Specifically, the user quotation function interacts with the electric vehicle users. The aggregator sends a program for providing user declaration data to the electric vehicle users through the user quotation function, thereby sending the collected declared electricity, the original consumption electricity and the user quotation to the transaction matching function.

[0113] The judgment submodule is used to identify whether the electric vehicle user is willing to participate in peak load regulation and to judge whether the user's declared data meets the constraints pre-set in the blockchain platform.

[0114] In this embodiment, the peak load willingness smart contract module also includes:

[0115] The transaction matching submodule is provided with a transaction matching function, which makes a matching peak-shaving decision based on the peak-shaving demand of the power grid and the user's declared data, wherein the peak-shaving decision includes a list of electric vehicle users participating in the peak-shaving, the declared power amount of each electric vehicle user and the user's quotation.

[0116] Specifically, the user registration function, user login function, peak-shaving invitation function, user quotation function, and transaction matching function communicate with each other through the smart contract within the module, so that they can transmit data to each other, and finally the peak-shaving decision is generated by matching the transaction matching function.

[0117] Embodiment 3

[0118] Please refer to Figure 2 and Figure 3 Based on the first and second embodiments, the constraints of the present invention include: peak-shaving price constraints, peak-shaving capacity constraints, and peak-shaving demand constraints. If the electric vehicle user is willing to participate in peak-shaving and satisfies the three constraints in the constraints at the same time, he / she will participate in peak-shaving; otherwise, he / she will exit peak-shaving.

[0119] Specifically, the specific steps for determining whether the user's declared data meets the constraints pre-set in the blockchain platform include:

[0120] The peak-shaving price constraint can be specifically: determining whether the user's bid is greater than or equal to the aggregator's subsidy price;

[0121] The peak load capacity constraint can be specifically: judging whether the declared power that can be consumed during the consumption period provided by each electric vehicle user is less than or equal to its regulation threshold. The regulation threshold is the maximum regulation capacity of the electric vehicle, which is used to avoid false declaration of power, which exceeds the maximum regulation capacity of the electric vehicle battery and thus causes damage to the battery;

[0122] The peak demand constraint can be specifically: judging whether the total declared electricity provided by all electric vehicle users is greater than or equal to the total electricity demand of the aggregator, so as to ensure that the total electricity provided by the aggregator is sufficiently consumed by all electric vehicles and to ensure the balance between supply and demand.

[0123] More specifically, the judgment process of the three constraints in the above constraints is automatically judged in sequence by the smart contract without the need for other software control. After the judgment is completed, if all are judged as yes, the result of satisfying the constraint conditions is output. After the smart contract receives the result that the user declaration data provided by the electric vehicle user meets the constraint conditions, it automatically executes the transaction matching function.

[0124] Of course, in other embodiments, the judgment process of the three constraints in the above constraint conditions can also be judged simultaneously through parallel instructions.

[0125] In this embodiment, if any one of the three constraints of the above constraints is judged to be negative, the peak-shaving operation is terminated, that is, the peak-shaving operation is not established, and the process jumps to step S23 to collect user declaration data again.

[0126] When the electric vehicle user is willing to participate in peak load regulation and satisfies three of the constraints, a matching peak load regulation decision is made based on the total electricity demand of the aggregator and the user's declared data.

[0127] Preferably, in order to ensure that the power grid's electricity is consumed in sufficient quantity, after the electric vehicle users are willing to participate in peak-shaving and meet the three constraints in the constraints at the same time, analyze whether the peak-shaving demand of the power grid is consistent with the total declared electricity provided by all users' declared data. If they are consistent, match the peak-shaving decision based on the peak-shaving demand of the power grid and the user's declared data.

[0128] More specifically, the peak-shaving demand of the power grid and the user's declared data are matched with the peak-shaving decision through the transaction matching function. The transaction matching function takes the maximization of revenue as the objective function, and the objective function is:

[0129]

[0130] Among them, i=1,2,3 is the number of electric vehicle users participating in peak load regulation, ΔW i =W i -W i ,, which means that electric vehicle users commit to charging capacity outside the plan in response to grid consumption, W i W is the reported amount of electricity that can be consumed during the consumption period, i , is the original power consumption, P average is the subsidy price, P i Provide quotes to users.

[0131] Specifically, the transaction matching function takes profit maximization as its objective function, which means ensuring that the aggregator's income is maximized.

[0132] In this embodiment, a supply-demand balance is maintained between the electricity provided by the aggregator and the electricity consumed by the aggregated electric vehicles, thereby improving the utilization rate of the power supply and maximizing the income of the aggregator, thereby ensuring the interests of the aggregator.

[0133] Specifically, before executing the transaction matching function, it is necessary to first determine whether the user-declared data meets the constraints. After the smart contract receives the result that the electric vehicle user is willing to participate in peak load regulation and the user-declared data meets the constraints, the transaction matching function is automatically executed.

[0134] In the device of the present invention, the constraints in the peak-shaving willingness smart contract module include: peak-shaving price constraints, peak-shaving capacity constraints and peak-shaving demand constraints. If the electric vehicle user is willing to participate in peak-shaving and satisfies the three constraints in the constraints at the same time, he will participate in peak-shaving, otherwise, he will exit peak-shaving.

[0135] Embodiment 4

[0136] On the basis of the first, second and third embodiments, the calculation formula of the subsidy settlement amount of the present invention is:

[0137]

[0138] Where i=1, 2, 3 is the number of electric vehicle users participating in peak load regulation, W actual,i is the actual amount of electricity consumed or provided, P i Provide quotes to users.

[0139] Specifically, the subsidy settlement amount is calculated based on the actual amount of electricity consumed or provided and the user's quotation. In the peak-shaving market, the calculated subsidy settlement amount is the remuneration that the aggregator pays to electric vehicle users.

[0140] The device of the present invention also includes a clearing smart contract module, which includes:

[0141] The market clearing and task allocation submodule is used to perform price clearing operations according to the peak load shaving decision and allocate peak load shaving tasks to each electric vehicle based on the price clearing operations.

[0142] Specifically, the actual charging or discharging amount consumed or provided and the user quotation are obtained, and the corresponding actual charging or discharging amount and the user quotation corresponding to each electric vehicle user are allocated to each electric vehicle according to the charging or discharging amount and the user quotation. In this embodiment, the user quotation is used as the final price for clearing.

[0143] A result settlement submodule is used to calculate and pay the subsidy settlement amount for each electric vehicle user according to the peak-shaving task, and record the subsidy settlement amount on the blockchain platform and provide a settlement report, wherein the peak-shaving task includes the actual amount of charging or discharging consumed or provided and the user's quotation;

[0144] In this embodiment, price clearing is performed according to the peak-shaving decision, and the electricity allocation and price determination of the peak-shaving task are carried out. The subsidy settlement amount is calculated according to the data of the peak-shaving task and the payment process is executed to send the subsidy settlement amount to the electric vehicle users participating in the peak-shaving to complete the remuneration reward.

[0145] Since the data of each node in this embodiment is recorded on the blockchain platform, the entire peak-shaving process is transparent, which increases the willingness of electric vehicles to cooperate. After the peak-shaving is completed, the settlement report is sent to the electric vehicle users, so that the electric vehicle users can verify the entire peak-shaving process, increase credibility, and attract more electric vehicles to participate in peak-shaving, thereby alleviating the pressure on the power grid.

[0146] In this embodiment, after collecting the peak-shaving participation willingness and user declaration data, the peak-shaving willingness smart contract module matches the peak-shaving decision, and the clearing smart contract module executes price clearing and determines the electricity allocation and price of the peak-shaving task according to the peak-shaving decision. The subsidy settlement amount is calculated according to the data of the peak-shaving task and the payment process is executed to send the subsidy settlement amount to the electric vehicle users participating in the peak-shaving and complete the remuneration reward.

[0147] Embodiment 5

[0148] On the basis of Example 1, Example 2, Example 3, and Example 4, the power grid peak-shaving demand, subsidy price, constraint conditions, and user declaration data of the present invention are all stored in a distributed manner on multiple nodes of the blockchain platform, and are matched to form a peak-shaving decision after consensus by at least two-thirds of the nodes.

[0149] Specifically, the present invention is applied on a blockchain platform to disperse and store various data on multiple nodes, which can simplify data processing and management processes and improve data processing efficiency.

[0150] Specifically, all the above data will be generated after consensus by at least two-thirds of the nodes, which also makes it extremely difficult to tamper with the data, thereby improving data security. The peak-shaving demand of the power grid and the user declaration data generated after consensus can be matched with the peak-shaving decision through the transaction matching function. The peak-shaving decision includes a list of electric vehicle users participating in the peak-shaving, the declared power of each electric vehicle user, and the user's quotation.

[0151] Embodiment 6

[0152] On the basis of Example 1, Example 2, Example 3, Example 4, and Example 5, the present invention uses data obfuscation technology to obfuscate the user declaration data uploaded by electric vehicle users to the blockchain platform.

[0153] Specifically, the user-declared data is obfuscated before being transmitted to the blockchain platform, making the data chaotic. The blockchain platform also stores the data in a chaotic order to increase the difficulty for attackers to crack the data.

[0154] In a specific embodiment, the user's declared data is open to the aggregator and the power dispatch center. The smart contract of the blockchain is uniformly published and uploaded by the aggregator, and the smart contract responds to the program of filling in the user's declared data form, so that the electric vehicle user can fill in the declared power consumption, the original consumption power consumption and the user's quotation that can be consumed during the consumption period. In this way, the aggregator can dynamically adjust the actual consumption of electric vehicles in the responsible area to match more suitable peak-shaving decisions.

[0155] To protect the interests of electric vehicle users, user-declared data is disclosed to both aggregators and power dispatching centers to prevent aggregators from tampering with user-declared data. The power dispatching center supervises the transaction process to ensure fairness.

[0156] In another specific embodiment, the user-declared data is open to the power dispatch center, but not to the aggregator. The smart contracts of the blockchain are uniformly published and uploaded by the power dispatch center. The aggregator is only responsible for managing the users who are willing to participate in the electric vehicle transaction, and does not participate in the peak-load transaction process. This prevents the aggregator from tampering with or leaking the user-declared data from the source, and ensures the fairness of the transaction process.
