TECHNICAL FIELD
[0001] The present application relates to the field of electric power information technology, and in particular to a frequency regulation market-oriented electric vehicle package design and parameter setting method and system. BACKGROUND
[0002] The statements in this section merely provide background information related to the present application and do not necessarily constitute the prior art.
[0003] Vehicle-to-grid (V2G) technology is developing rapidly, and electric vehicles (EV) capable of bidirectional energy flow with the power grid can be seen as a large number of distributed energy storage resources providing frequency regulation support for the power grid. EV participation in power grid frequency regulation has become a new business model. With the increasing penetration of renewable energy, the demand for power grid frequency regulation is increasing. EVs with distributed characteristics and rapid response capabilities have great potential in stabilizing renewable energy fluctuations and improving power grid stability. Therefore, how an electric vehicle aggregator (EVA) adopts strategies to encourage users to participate in the frequency regulation market has become a key factor in its success in business competition. As a win-win value-added service of the power selling party, the package can solve the problems of multiple power selling parties and complex electricity pricing mechanisms that users encounter in the process of seeking power selling agents. However, unreasonable package design can result in deep discharge, high rate charge and discharge, and low user benefits, thereby reducing the willingness of users to participate in frequency regulation. Therefore, for an EVA, it is very important to design a frequency regulation package and use an appropriate method to analyze package selection to optimize parameter settings.
[0004] In terms of package design, existing research focuses on scheduling targets such as peak shaving and low carbon, and designs packages based on load charging characteristics. However, no research has considered the frequency regulation characteristics of EVs and designed corresponding frequency regulation subsidy packages.
[0005] In terms of parameter setting, existing research only considers the response willingness of users and does not combine a global optimization model with bidding revenue in the electricity market. Moreover, simple models are used to describe the selection behavior of users, which cannot accurately depict the complex psychology of scattered users when making selections.
[0006] In terms of user selection psychology, there have been many studies abroad on the use of fuzzy decision-making for qualitative recommendations. These studies have been proven effective in charging scheduling, site selection, road traffic analysis, and vehicle path decision-making. The above studies are based on different influencing factors and evaluate the preferences of EV users through fuzzy theory. However, the above studies lack a fuzzy evaluation system under the influence of frequency regulation participation, and the evaluation of fuzzy set membership lacks a theoretical basis. SUMMARY
[0007] To solve the technical problems in the background art, the application provides a method and system for designing and formulating parameters of electric vehicle packages for frequency modulation markets.

[0009] The method for designing and formulating parameters of electric vehicle packages for frequency modulation markets comprises the following steps: Based on the discharge frequency modulation participation, the mandatory retention time length and the privacy information, a plurality of retail frequency modulation packages are constructed, and a charging subsidy price is configured for each package. According to the provision of charging information, participation in discharge frequency modulation, willingness to stay at the charging station for a long time and user price sensitivity, four evaluation criteria are set in turn. The historical data of users are obtained, and the user preference fuzzy set of the users under the evaluation criteria is constructed according to the acceptance degree of the users to the evaluation criteria.

[0036] Compared with the prior art, the present application has the following beneficial effects: The application proposes a dynamic decision model based on a double-layer optimization framework, aiming to realize intelligent optimization of electric vehicle frequency modulation package parameters. Through data interaction and iterative calculation between the upper and lower layers, the model effectively balances the complex relationship between user selection preferences and aggregator economic benefits. In the lower layer model, the system first aggregates user groups with similar selection tendencies based on different package selection results of users. By analyzing the combined characteristics of discharge participation and retention time, users are divided into four typical clusters. In the upper layer model, the aggregator establishes a multi-objective optimization decision system by comprehensively considering frequency modulation market revenue and various operating costs. This system not only needs to calculate the frequency modulation capacity value provided by each user cluster, but also needs to fully consider key factors such as electricity purchase cost, package subsidy expenditure, and risk cost due to user behavior prediction deviation. By dynamically adjusting key variables such as retention time and subsidy price in the package parameters, and feeding back the optimization results to the lower layer model for a new round of user selection probability calculation, a closed-loop optimization mechanism is formed. The improved particle swarm algorithm is used for solving, and through multiple iterations, the optimal balance solution between user satisfaction and aggregator revenue is finally obtained. The model verification results show that this two-way feedback optimization mechanism can significantly improve the overall performance of the system, while ensuring the user's selection freedom, maximizing the economic benefits of the aggregator, and providing a scientific and effective decision support tool for electric vehicle frequency modulation services in the power market environment. This model not only solves the limitations of traditional optimization methods that cannot balance the interests of multiple parties, but also provides an important reference for demand response mechanism design in new power systems through intelligent dynamic adjustment of parameters.

[0042] As introduced in the background, (1) existing researches mostly focus on peak shaving, low carbon, and other dispatching targets, and design packages according to load charging characteristics, but there is no research based on the frequency modulation characteristics of EVs and the corresponding frequency modulation subsidy package is designed. (2) Existing technologies only consider price optimization. (3) EV aggregators need to establish a decision-making model to estimate the day-ahead frequency modulation capacity. However, existing research lacks a fuzzy evaluation system under the influence of participation in frequency modulation, and the evaluation of fuzzy set membership lacks theoretical basis.
[0043] In order to solve the above problems, the present application provides a frequency modulation market-oriented electric vehicle package design and parameter setting method and system. The scheme of the present application will be described in detail below through several embodiments.
[0044] Figure 1 is a flowchart of the frequency modulation market-oriented electric vehicle package design and parameter setting method shown in the embodiment of the present application; refer to Figure 1 , the method comprises: Based on the discharge frequency modulation participation, the forced retention time, and the privacy information, a plurality of retail frequency modulation packages are constructed, and a charging subsidy price is configured for each package; According to the provision of charging information, participation in discharge frequency modulation, willingness to stay for a long time at the charging station, and user price sensitivity, four evaluation criteria are set in turn; Obtaining user historical data, constructing user preference fuzzy set of the user under the evaluation criteria according to the acceptance degree of the user to the evaluation criteria; calculating the degree of conformity of the package to the evaluation criteria based on all retail frequency modulation packages, constructing package intuitionistic fuzzy set of each package under the evaluation criteria; matching the user and the package based on the user preference fuzzy matrix of the user under the evaluation criteria and the package intuitionistic fuzzy matrix of each package under the evaluation criteria, obtaining a similarity measure matrix, calculating the probability of the user selecting a certain package, and obtaining a user package selection probability matrix; Based on the user package selection probability matrix, the package subsidy cost is determined; based on the energy purchase cost, the package subsidy cost, the expected risk cost and the frequency modulation income, a target function is constructed, and the optimal scheme is solved combined with the constraint condition.
[0045] The application establishes a double-layer optimization model: the upper layer takes the maximum income of EVA participating in the day-ahead market as the target, and dynamically optimizes the package parameters; the lower layer establishes a package selection model considering user satisfaction, and transmits the selection result to the upper layer for iteration.
[0046] 1. Frequency modulation package design 1) EV grid-connected model In the intelligent charging station, the charging pile is equipped with an edge, which can receive the real-time frequency modulation signal of the upper power grid and control the EV to start or stop charging and discharging, and monitor the cloud server and sensor operation state of the charging vehicle, so that the battery energy can always be kept in the operable area. The grid-connected state of the electric vehicle equipped with V2G function can be divided into three modes of charging-idling-discharging. The existing related research describes the scheduling flexibility of a single EV through a grid-connected model, as shown in the figure. The red line encloses the upper and lower boundaries of the operable area. Figure 2
[0047] 2) Frequency modulation package design As can be seen from the grid-connected model, if the vehicle can enter the discharging mode, the range of its operable area will be widened, that is, the frequency modulation capacity will be improved. At the same time, appropriately prolonging the user's stay time in the charging station can improve the EV frequency modulation capacity. Some users are unwilling to upload key information such as battery capacity and next day entering charging station time, and the lack of these information will increase the risk loss in the operation process. By providing subsidies to these users, information sharing can be encouraged, and the risk loss caused by prediction error can be reduced.
[0048] Based on the user discharging mode participation, the difference in stay time and the demand for privacy protection, eight kinds of retail frequency modulation packages are designed as shown in Table 1, each package has different subsidies. Among them, the stay time and the subsidy price are the package parameters that change within a certain range.
[0049] Table 1: Frequency modulation package settings
[0050] The application is based on in-depth analysis of electric vehicle user behavior characteristics and systematic research on grid-connected model of electric vehicles, and proposes an innovative differentiated frequency modulation package design scheme. By establishing a coupling model of electric vehicles participating in power grid frequency modulation, three core user behavior characteristics are first identified and quantified, including: (1) the willingness of users to participate in discharge frequency modulation; (2) the time preference of users at the charging station; (3) the tendency of users to provide vehicle privacy information. These characteristics not only directly determine the potential ability of electric vehicles to participate in power grid frequency modulation, but also have a significant impact on the operation and dispatch of power systems.
[0051] Based on this, the research innovatively constructs a multi-dimensional frequency modulation package system, which includes 8 types of differentiated combination schemes. Each package is composed of four key dimension parameters: first, the discharge frequency modulation participation dimension, which directly determines whether the vehicle can provide discharge service through V2G technology, thereby significantly expanding the frequency modulation capacity of the power grid; second, the mandatory residence time dimension, which can greatly improve the flexibility and response ability of system frequency modulation by appropriately extending the vehicle's residence time at the charging station; third, the privacy information provision dimension, which encourages users to share key data such as battery capacity and arrival time at the station to more accurately predict and dispatch frequency modulation resources and reduce uncertainty risks; and fourth, the charging subsidy price dimension, which provides differentiated economic incentives according to different combinations of the first three dimensions.
[0052] Based on the grid-connected model, the application extracts three user behavior characteristics that affect the frequency regulation capability of electric vehicles. For these characteristics, eight types of packages are designed that cover discharge frequency adjustment needs, time flexibility preferences, and privacy protection tendencies.
[0053] 2. Lower layer fuzzy set-based package selection model 1) User fuzzy set establishment Set Four evaluation criteria are used to evaluate users and packages respectively. They represent providing charging information, participating in discharge frequency modulation, willingness to stay at the charging station for a long time, and user price sensitivity. Assuming there are EV users and criteria, their historical data upload permission, V2G function installation, reservation charging period selection, historical data such as charging price sensitivity, and past package selection are collected through questionnaires to obtain the user Fuzzy set of user under criterion (1) In the formula, The physical meaning is the user's criteria. The level of acceptance. express users The fuzzy matrix composed of fuzzy sets under the criteria: (2) 2) Fuzzy evaluation of packages Assuming the number of packages is Get the package In the guidelines Fuzzy sets below: (3) (1) Standard : Guidelines and These respectively represent providing charging information and participating in discharge frequency regulation, which are directly related to the package attributes and are evaluated as binary constants. (In the criteria...) Under these circumstances, packages one, two, three, and four do not require any information, therefore their compliance rate is 0. (Based on the criteria...) The attributes of packages three, four, seven, and eight indicate that users must participate in discharge frequency modulation after selecting these packages, so their compliance rate is 1. Other packages do not have this requirement, so their compliance rate is 0.
[0054] (4) (5) (2) Standard : Guidelines The purpose is to assess the mandatory stay time of the package. Ideal user dwell time The degree of deviation was assessed. A first conformity function was constructed using statistical methods to quantify the degree of matching in terms of dwell time. First conformity evaluation function. It adopts a Gaussian-like distribution form: (6) In the formula, The mandatory stay time for the package This is the adjustment parameter for the time deviation. This function describes how close the residence time is to the ideal time: when... near When the two deviate significantly, the degree of agreement reaches its maximum; when the two deviate significantly, the degree of agreement decreases exponentially.
[0055] (3) Standard
[0056] Guidelines Evaluate the suitability of the package pricing parameters for users' price preferences. Similarly, design a second suitability evaluation function. This is to quantify users' acceptance of the price points within the range of subsidized pricing.
[0057] The second conformity function uses an adjusted Sigmoid function to represent the trend that the degree of conformity to the standard gradually increases as the price rises.
[0058] (7) in, For package pricing parameters, Steepness is used to control the growth rate of the second conformity function as price changes. The center value of the price is used to adjust the translation position of the Sigmoid function. , This is the price compliance assessment coefficient.
[0059] Thus, you can get a package deal. In the guidelines The following evaluation value .use express Each package is available at The fuzzy matrix composed of the evaluation values under each criterion is shown in Equation (8).
[0060] (8) 3) Similarity assessment Define a similarity metric based on weighted Euclidean distance to match users with packages, where, Here, we define the weight for each criterion, assuming all criteria have the same weight. In the formula... This represents the similarity between users and service packages under the Euclidean distance.
[0061] (9) Thus, the similarity metric matrix is obtained. : (10) This represents user satisfaction with the package. Based on this, user... Select Package probability : (11) This yields the probability matrix of user plan selection. : (12) To effectively address the fuzziness and uncertainty of user preferences, this study constructs a multidimensional evaluation model based on fuzzy set theory. This model quantifies user preferences from four key dimensions and calculates the user's matching degree and selection probability for different FM packages accordingly: (1) Information support level: reflects the degree of user acceptance of sharing privacy information, and directly affects the system's prediction accuracy of frequency modulation resources; (2) Discharge frequency regulation participation: measures whether users are willing to participate in reverse discharge frequency regulation and determines their potential to expand the grid regulation capacity; (3) Dwell time matching degree: assess the degree of fit between the user's actual charging behavior and the package requirements. This factor significantly affects the continuity and flexibility of frequency modulation service; (4) Price sensitivity: This describes the user's response to economic incentives and determines the actual attractiveness of the package subsidy.
[0062] 3. Upper-level EVA Day-to-Day Market Bidding Strategy Model 1) EV aggregation model Assume the number is The EV belongs to the cluster The cluster's overall maximum and minimum power Maximum and minimum capacity It can be represented as: (13) (14) in, For clusters The number of EVs.
[0063] Since the grid connection and off-grid operation of EVs will affect the energy boundary of the cluster, equations (15)-(16) define the energy boundary under grid connection conditions. Energy boundary in the off-grid state In the formula and They are numbered as follows EV represents the maximum energy at time t and time t+1.
[0064] (15) (16) in, Indicates EV in The grid connection status at any given time is 1 for grid connection and 0 for off-grid. The corrected energy storage capacity of the EV cluster, etc. As shown in equation (17). In the equation... Let be the equal energy storage power of cluster j at time t.
[0065] (17) 2) EVA's participation in the day-ahead energy-frequency modulation market model EVAs can participate in day-ahead electricity market bidding and trading as resource agents, bidding in a clustered aggregation format. Their day-ahead objective is to minimize the sum of energy purchase costs, package subsidy costs, and risk prediction costs while meeting user charging needs, and to maximize revenue in the frequency regulation market. The objective function can be written as: (18) in, To purchase energy costs, The cost of the package subsidy is shown in equations (19) and (20), respectively.
[0066] (19) (20) in, To purchase the aggregate power of EVs in package k, The price for purchasing energy. For package parameters, Choose the option for the user.
[0067] To quantify the impact of time deviations of users who did not provide charging information on the system's frequency regulation capacity, a risk function is defined. First, for user i, their predicted arrival time is... Actual arrival time satisfy: (twenty one) in, This is the time deviation term. This is a binary variable representing whether a user is willing to provide information. The frequency modulation capacity deviation is defined. for: (twenty two) Then the expected risk cost for: (twenty three) in, The unit deviation penalty coefficient, and These are the frequency modulation capacities based on predicted time and actual time, respectively.
[0068] The time-domain distribution of reserve capacity available for auxiliary frequency regulation services is calculated using an equal energy storage model and used as the frequency regulation capacity to be reported to the frequency regulation market. (twenty four) (25) In the formula, , Adjust the aggregate capacity of EVs for cluster j. , Capacity limits are specified for providing auxiliary frequency modulation (FM) services. This allows for the calculation of FM revenue. In the formula and The capacity price is adjusted up or down at time t.
[0069] (26) The constraints are the boundary limits of the equivalent energy storage model: (27) (28) (29) in, , Let j be the equivalent energy storage power and energy boundary of aggregate j. , This refers to the grid-connected and off-grid boundary energy of aggregate k. , Let be the same energy storage capacity of cluster j at time t and time t+1. Let be the equal energy storage power of cluster j at time t. The time difference is represented. This formula represents the relationship between energy and power under the constraint of equal energy storage, and the specific derivation is shown in equation (17).
[0070] This invention utilizes fuzzy sets to represent the uncertainty in user choice behavior and constructs a user package selection model. Ultimately, it establishes a two-layer optimization model with maximizing aggregator revenue as the upper-level objective and user choice behavior as the lower-level guide.
[0071] This invention first establishes a fuzzy set of user preferences using questionnaires and historical behavioral data to quantify their acceptance of each dimension. Based on this, two types of key functions are designed to evaluate the suitability of the service packages: The dwell time matching degree is modeled using a Gaussian function-like method. The matching degree reaches its peak when the mandatory duration of the package is close to the user's ideal time, and then decays exponentially as the deviation increases, accurately capturing the user's sensitivity to time flexibility. Price sensitivity is calculated based on an improved Sigmoid function. The higher the subsidy price, the faster the user acceptance grows, but the marginal utility diminishes, ensuring the rationality of economic incentives.
[0072] By employing a weighted Euclidean distance algorithm, the similarity of user satisfaction with each service plan under multi-dimensional criteria is comprehensively calculated and transformed into a probability distribution of user selection of different plans. This model not only effectively solves the ambiguity problem in user decision-making but also provides a quantitative basis for system operators to optimize plan design, achieving precise matching between supply and demand.
[0073] Finally, a dynamic decision-making model based on a two-layer optimization framework is proposed to achieve intelligent optimization of electric vehicle frequency regulation package parameters. This model effectively balances the complex relationship between user preferences and aggregator economic benefits through data interaction and iterative calculation between the upper and lower layers. In the lower-layer model, the system first aggregates user groups with similar selection tendencies based on different package choices. By analyzing the combined characteristics of discharge participation and dwell time, users are divided into four typical clusters. In the upper-layer model, the aggregator establishes a multi-objective optimization decision-making system by comprehensively considering frequency regulation market revenue and various operating costs. This system not only needs to calculate the frequency regulation capacity value that each user cluster can provide, but also fully considers key factors such as electricity purchase costs, package subsidy expenditures, and risk costs due to user behavior prediction biases. By dynamically adjusting key variables such as dwell time and subsidy prices in the package parameters, and feeding the optimization results back to the lower-layer model for a new round of user selection probability calculation, a continuously iterative closed-loop optimization mechanism is formed. The study uses an improved particle swarm optimization algorithm for solving the problem, and through multiple iterations, a solution that achieves the optimal balance between user satisfaction and aggregator revenue is finally obtained.
[0074] Model validation results demonstrate that this bidirectional feedback optimization mechanism significantly improves the overall system performance, maximizing the economic benefits for aggregators while ensuring user freedom of choice. This provides a scientific and effective decision support tool for electric vehicle frequency regulation services in the electricity market environment. The model not only overcomes the limitations of traditional optimization methods in balancing the interests of multiple parties but also provides an important reference for the design of demand response mechanisms in new power systems through intelligent dynamic parameter adjustment.
[0075] To verify the scheme of this invention, charging behavior data of 50 EVA vehicles with a battery capacity of 60 kWh and maximum charging and discharging powers of 6 kW and 5 kW respectively were selected. Based on their travel patterns, the Monte Carlo method was used to simulate the users' arrival time and minimum expected power upon departure. A survey was conducted on these users to obtain their fuzzy coefficients. The current pricing references the pricing of demand-side resource reserves in foreign electricity markets.
[0076] In the case study analysis, the impact of providing charging information, participating in discharge frequency regulation, willingness to stay at charging stations for extended periods, and the user's price sensitivity on the user is set to be 0.2, 0.3, 0.3, and 0.2, respectively. Through comprehensive evaluation and analysis, the following settings are established: It is 8. It is 1.4. The value is 2. It is 0.6. It is 0.5. It is 16.
[0077] Through questionnaire surveys and collected user history data, we can obtain information about users'... Fuzzy preferences under four criteria, such as Figure 3 As shown in the figure, users are generally highly sensitive to price and dwell time, while their support for providing personal information is mostly in the middle range, indicating a relatively neutral preference. Furthermore, most users have a low willingness to participate in frequency modulation for discharge, but there is considerable room for hesitation.
[0078] User package selection results are as follows: Figure 4 As shown in the results, packages 3, 5, and 7 have the highest user satisfaction. Furthermore, some users who are hesitant about participating in discharge frequency regulation may still choose packages that include this feature. Meanwhile, packages 6 and 8 also have high satisfaction rates, indicating that most users are willing to adjust their behavior to support charging solutions that improve EV frequency regulation capabilities, provided there are appropriate subsidies or incentives.
[0079] Since the EV grid-connected model is directly affected by the frequency regulation method and charging time, users who have selected different packages will be aggregated according to whether they participate in discharge frequency regulation and the different times they stay at the charging station: Aggregation 1: Users who choose Package 1 and Package 5, which do not accept discharge frequency modulation and have short dwell times.
[0080] Aggregation 2: Users who choose Package 2 and Package 6 who do not accept discharge frequency modulation and have long dwell times.
[0081] Aggregation 3: Users who choose to accept discharge frequency modulation and have short dwell time in Package 3 and Package 7.
[0082] Aggregation 4: Users who choose to accept discharge frequency modulation and have a long dwell time in Package 4 and Package 8.
[0083] Upward and downward regulation capacity obtained in the energy-frequency regulation market, such as Figure 5 and Figure 6 As shown.
[0084] Combination Figure 5 and Figure 6Looking at the capacity increases, the capacity increase for aggregated EVs is stronger during the early morning (0:00 to 7:00) and afternoon (12:00 to 16:00) hours than at other times. This is because vehicle driving demand increases during other times, while charging resources are relatively reduced. Packages 7 and 8 are the most popular choices. These packages all provide discharge frequency regulation and charging information, indicating that many users are willing to choose packages with better frequency regulation to obtain more subsidies.
[0085] In terms of capacity reduction, the reduction capacity is significantly better during nighttime hours, especially between 9:00 PM and midnight. The capacity reduction during the early morning hours is lower because most charging vehicles have already reached their charging limits, making further power reduction impossible. Furthermore, due to... Figure 5 It is known that the price increase reached its peak during this period, and providing resources with higher prices yielded higher returns.
[0086] To investigate the impact of different package parameter settings on revenue and user satisfaction, three scenarios were designed (as shown in Table 2): Scenario 1 represents the optimal package parameters obtained through two-level iterative optimization; Scenario 2 represents the minimum value of the package parameters; and Scenario 3 represents the maximum value of the package parameters. The revenue, subsidy costs, and user satisfaction under the three scenarios are shown in Table 3.
[0087] Table 2 Parameters of Packages for Different Scenarios
[0088] Table 3 Comparison of Parameters and Scenarios for Different Packages
[0089] In scenario two, the package parameters are set to the minimum, resulting in low subsidy amounts and low user dwell time, leading to a negative total subsidy revenue. However, because low dwell time better meets the needs of most users, user satisfaction is maximized. This approach of simply pursuing user satisfaction at the expense of subsidies and service time fails to fully leverage users' frequency tuning potential and also impacts the aggregator's economic benefits.
[0090] In scenario three, the package parameters are set to the maximum value, the subsidy amount increases significantly, and the user's dwell time is significantly prolonged. However, the long dwell time affects the user experience, reduces users' willingness to choose the response package, and the higher subsidy cost also reduces the overall revenue.
[0091] This invention comprehensively considers the balance between EVA (Economic Value Added) benefits and user satisfaction through parameters obtained through two-layer optimization. The optimized parameter design ensures an appropriate subsidy amount and a reasonable user retention time, maximizing total benefits. In terms of user satisfaction, Scenario 1 also maintains a high level. This indicates that the optimized package can balance user experience and EVA benefits, demonstrating the effectiveness of the parameter optimization model.
