Description

Technical Field

[0001] The present invention relates to the technical field of charging station electricity price response, and in particular to a charging station operation strategy adjustment method. Background Art

[0002] As an important part of sustainable development in the transportation sector, electric vehicles (EVs) have been considered an important development direction for solving the energy crisis and greenhouse gas emissions. In order to provide users with charging services in a short period of time and meet the fast charging needs of users during travel, fast charging technology is gradually replacing the traditional slow charging mode. Considering the unified electricity price, car owners usually charge their vehicles according to their behavioral habits, which will lead to concentrated charging in certain time periods, and few or even no vehicles charging in certain time periods, which is not conducive to the operation of charging stations, and the power supply pressure is high during the peak charging period, which is not conducive to safe and stable power distribution.

[0003] Existing technologies usually use time-of-use electricity prices to divide the 24 hours of a day into multiple time periods, and set different fixed charging unit prices according to each time period. For example, the charging unit price is increased during time periods with more concentrated charging, and the charging unit price is reduced during time periods with fewer charging vehicles. The charging willingness of car owners is regulated by price, thereby shifting peaks and filling valleys in the time dimension, reducing the power supply pressure during peak charging time periods, and making the operation of charging stations more stable.

[0004] However, as the number of electric vehicles increases, the uncertainty of user travel has an increasing pressure on charging. For example, during certain holidays or events, concentrated charging may occur during time periods when there are fewer charging vehicles. At this time, the originally set fixed charging unit price cannot play the role of charging regulation. This leads to limited regulation of charging vehicles by setting fixed charging unit prices in different time periods. That is, the existing technology uses time-of-use electricity prices to set different fixed charging unit prices for each time period, which has poor regulation ability for charging vehicles and low robustness of the corresponding charging station operation strategy. Summary of the invention

[0005] The present application provides a charging station operation strategy adjustment method, which determines a preliminary adjustment charging unit price based on a preset charging unit price according to the total number of charging vehicles in the current time-sharing period in historical data; then determines the charging attraction degree that characterizes the charging willingness of each to-be-charged vehicle to the charging station to be adjusted in terms of distance and service fee; then characterizes the demand for charging scheduling of charging vehicles at the charging station to be adjusted in terms of attracting vehicles to charge according to the attraction control weight determined by the charging attraction degree; then determines the queue control weight according to the characteristic that the more uneven the number of charging vehicles queuing for charging at each charging station and the more saturated the number of charging vehicles queuing for charging at the charging station to be adjusted, the greater the demand for vehicle charging scheduling; thereby comprehensively determining the unit price control weight that characterizes the demand for vehicle charging scheduling by combining the attraction control weight and the queue control weight; finally, adjusts the preliminary adjustment charging unit price according to the unit price control weight, so that the charging willingness of the vehicle owner is changed in terms of price according to the obtained charging unit price to be adjusted, so that the ability to control the charging vehicle is stronger and more reasonable, solves the problem that the method of setting different fixed charging unit prices for each time-sharing period in the prior art by using time-sharing electricity prices has poor ability to control the charging vehicle, and improves the robustness of the charging station operation strategy.

[0017] In a third aspect, the present application provides a computer device, comprising a memory and a processor.

[0018] In a fourth aspect, the present application provides a computer program product, comprising a computer program code, which, when executed, performs the method of the first aspect of the present application or any embodiment of the first aspect.

[0019] In a fifth aspect, the present application provides a computer-readable storage medium, wherein the computer-readable storage medium stores a computer program code. When the computer program code is executed, the method of the first aspect or any embodiment of the first aspect of the present application is performed.

[0020] This application has the following beneficial effects: The more charging vehicles there are at the charging station to be adjusted in the current time-sharing period in the historical data, the more concentrated the charging behavior at the charging station to be adjusted in the current time-sharing period. At this time, in order to maintain the stability of the charging station operation and the stability of power distribution, the greater the demand for dispatching charging vehicles to other time periods or other charging stations for charging; and the regulation of charging vehicles is passive, so it is necessary to use price means to indirectly adjust the charging willingness of car owners, thereby indirectly dispatching charging vehicles in the time dimension or space dimension; therefore, this application first combines the number of charging vehicles per day at the charging station to be adjusted in the current time-sharing period in the historical data and the preset charging unit price, and first determines the charging unit price after preliminary regulation.

[0021] It is further necessary to consider that the travel of users, namely electric car owners, is uncertain. The preliminary adjustment of charging unit prices determined only based on the number of historical charging vehicles is obviously not accurate enough and cannot accurately reflect the current scheduling needs in real time. For electric car owners, the choice of charging station is affected by both distance and cost; the closer the charging station is, the more convenient charging is and the more attractive charging is; the lower the service fee, the higher the cost-effectiveness of charging at the corresponding charging station and the greater the attractiveness of charging; at the same time, it is also necessary to consider that the less the remaining power of the vehicle to be charged, the greater the owner's anxiety about electricity consumption will be, and the higher the demand for a charging station close to the vehicle at this time, and the greater the impact of distance on the choice of charging station for the vehicle to be charged; therefore, in combination with the above characteristics, the charging attractiveness of the charging station to be adjusted for each vehicle to be charged is comprehensively determined based on the location of each vehicle to be charged, the remaining power and the service fee of each charging station; thus, the attraction control weight is determined based on the numerical distribution of each charging attraction corresponding to the charging station to be adjusted, so that the greater the attraction control weight, the stronger the willingness of the vehicle to be charged to go to the charging station to be adjusted for charging, that is, the greater the potential charging pressure of the charging station to be adjusted, which means that the charging station to be adjusted has a greater demand for vehicle charging scheduling under the current time-sharing period.

[0022] For the area where the charging station to be adjusted is located, the more uneven the number of vehicles queuing for charging in each charging station in the current time-sharing period, the more the area needs to promote vehicle scheduling in terms of maintaining the stable operation of each charging station and the stable power supply pressure; and the more vehicles queuing for charging at the charging station to be adjusted in the current time-sharing period, the closer the charging vehicles at the charging station to be adjusted are to saturation, and the greater the corresponding demand for scheduling to other charging stations or other time-sharing periods for charging; therefore, according to the uneven distribution of the number of vehicles queuing for charging at all charging stations and the saturation of the number of vehicles queuing for charging at the charging station to be adjusted, the demand for vehicle charging scheduling is further characterized by the obtained queuing control weight.

[0023] The charging station can only dispatch vehicles passively and cannot actively command or require car owners to choose other charging stations. Therefore, the charging unit price is usually adjusted to increase or reduce the charging vehicle flow to indirectly dispatch vehicle charging. The attraction control weight and the queue control weight can both characterize the demand for vehicle dispatch to a certain extent. Therefore, the unit price control weight that characterizes the adjustment range of the charging unit price is finally determined in combination with the attraction control weight and the queue control weight. The preliminary regulated charging unit price is adjusted in combination with the unit price control weight, and a more accurate charging unit price to be adjusted corresponding to the charging station to be adjusted in the current time-sharing period is adaptively determined. This makes the ability to regulate charging vehicles stronger and more reasonable, solves the problem that the existing technology uses time-sharing electricity prices to set different fixed charging unit prices for each time-sharing period, and has poor ability to regulate charging vehicles, and improves the robustness of the charging station operation strategy.

[0027] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0028] A specific scheme of a charging station operation strategy adjustment method provided by the present invention is described in detail below with reference to the accompanying drawings.

[0029] This application embodiment provides a charging station operation strategy adjustment method, please refer to Figure 1 , which shows a flow chart of a charging station operation strategy adjustment method provided by an embodiment of the present invention, the method comprising: Step S101: Obtain the preset charging unit price of the charging station to be adjusted in each time-sharing period; determine the preliminary adjusted charging unit price of the charging station to be adjusted in the current time-sharing period according to the number of charging vehicles per day at the charging station to be adjusted in the current time-sharing period in historical data combined with the corresponding preset charging unit price.

[0030] In a specific implementation of an embodiment of the present invention, the 24 hours of each day are evenly divided into 12 time-sharing periods, each time-sharing period is 2 hours in length, and the starting time of each time-sharing period is an even integer, for example, 0:00 to 2:00 is a time-sharing period, and 2:00 to 4:00 is a time-sharing period; and the same preset charging unit price is set in all time-sharing periods of the charging station to be adjusted; in a specific implementation of an embodiment of the present invention, the preset charging unit price is set to 0.5 yuan per kilowatt-hour, and the division of the time-sharing periods and the preset charging unit price of each time-sharing period can be adjusted according to the specific implementation environment, which will not be further elaborated here.

[0031] The more charging vehicles there are at the charging station to be adjusted in the current time-sharing period in the historical data, the more concentrated the charging behavior at the charging station to be adjusted in the current time-sharing period. At this time, in order to maintain the stability of the charging station operation and the stability of power distribution, the greater the demand for scheduling charging vehicles to other time periods or other charging stations for charging; and the regulation of charging vehicles is passive, so it is necessary to indirectly adjust the owner's charging willingness with the help of price means, thereby indirectly scheduling charging vehicles in the time dimension or space dimension; therefore, this application first combines the number of charging vehicles per day at the charging station to be adjusted in the current time-sharing period in the historical data and the preset charging unit price, and first determines the charging unit price after preliminary regulation. It should be noted that all data used in the embodiments of the present invention are data that the user has authorized, and no further elaboration will be made later.

[0032] Preferably, in some possible implementations of the embodiments of the present invention, the process of obtaining the initial regulation charging unit price includes: In the historical data, the average number of charging vehicles in all days of the charging station to be adjusted in the current time-sharing period is used as the historical load degree of the charging station to be adjusted in the current time-sharing period; according to the product of the positive correlation mapping value of the historical load degree and the preset charging unit price, the preliminary adjustment charging unit price of the charging station to be adjusted in the current time-sharing period is determined. In a specific implementation of the embodiment of the present invention, the number of days of the historical data is set to all days in the month before the current day.

[0033] In the historical data of each day corresponding to the current time-sharing period, the more charging vehicles there are at the charging station to be adjusted, that is, the greater the historical load level, the more concentrated the charging behavior at the charging station to be adjusted in the current time-sharing period, and the greater the demand for dispatching charging vehicles to other time periods or other charging stations for charging, that is, it is necessary to reduce the charging behavior at the charging station to be adjusted in the current time-sharing period, so price means are used to promote more vehicles to charge at other charging stations or other time-sharing periods; therefore, the greater the historical load level, the higher the charging unit price that needs to be regulated; therefore, the preset charging unit price is weighted by the positive correlation mapping value of the historical load level, and the regulated charging unit price of the charging station to be adjusted in the current time-sharing period is preliminarily determined.

[0034] In a specific implementation of the embodiment of the present invention, the process of obtaining the initial regulation charging unit price is expressed by the formula: ;in, The charging station to be adjusted in the current time-sharing period The initial regulation of charging unit price; To preset the first positive correlation mapping parameter, the embodiment of the present invention is set to 0.5, which can be adjusted according to the specific implementation environment; The charging station to be adjusted in the current time period in the historical data The average number of charging vehicles on all days, that is, the number of charging stations to be adjusted in the current time period The historical load level; The charging station to be adjusted in the current time-sharing period The preset charging unit price.

[0035] It should be noted that the number of vehicles charged at the charging station to be adjusted every day in the current time-sharing period in the historical data is specifically: the number of vehicles charged at the charging station to be adjusted every day from the beginning to the end of the current time-sharing period before the day; and the subsequent analysis is not historical data, but a real-time analysis of the current time-sharing period of the day. Therefore, when analyzing the current time-sharing period in the subsequent process, the collected data are all data corresponding to the 5 minutes before the start of the corresponding time-sharing period, that is, when analyzing the data under the current time-sharing period, the collected data is actually the data corresponding to the 5 minutes before the current time-sharing period, so as to adjust the operation strategy of the charging station to be adjusted in the current time-sharing period according to the data analysis results; analyzing 5 minutes in advance can enable the owners of the vehicles to be charged to respond to changes in the charging unit price, and can also adjust the time length according to the specific implementation environment, or the implementer can also analyze the data at the starting time of each time-sharing period according to the specific implementation environment, that is, adjust the charging unit price in real time at the beginning of each time-sharing period, which will not be further elaborated here.

[0036] Step S102: In the area where the charging station to be adjusted is located in the current time-sharing period, the charging attractiveness of the charging station to be adjusted for each vehicle to be charged is determined according to the location of each vehicle to be charged, the remaining power and the service fee of each charging station; according to the numerical distribution of the charging attractiveness of each vehicle to be charged corresponding to the charging station to be adjusted in the current time-sharing period, the attractiveness control weight of the charging station to be adjusted in the current time-sharing period is determined.

[0037] It is further necessary to consider that the travel of users, namely electric car owners, is uncertain. The preliminary adjustment of charging unit prices determined only based on the number of historical charging vehicles is obviously not accurate enough and cannot accurately reflect the current scheduling needs in real time. For electric car owners, the choice of charging station is affected by both distance and cost; the closer the charging station is, the more convenient charging is and the more attractive charging is; the lower the service fee, the higher the cost-effectiveness of charging at the corresponding charging station and the greater the attractiveness of charging; at the same time, it is also necessary to consider that the less the remaining power of the vehicle to be charged, the greater the owner's anxiety about electricity consumption will be, and the higher the demand for a charging station close to the vehicle at this time, and the greater the impact of distance on the choice of charging station for the vehicle to be charged; therefore, in combination with the above characteristics, the charging attractiveness of the charging station to be adjusted for each vehicle to be charged is comprehensively determined based on the location of each vehicle to be charged, the remaining power and the service fee of each charging station; thus, the attraction control weight is determined based on the numerical distribution of each charging attraction corresponding to the charging station to be adjusted, so that the greater the attraction control weight, the stronger the willingness of the vehicle to be charged to go to the charging station to be adjusted for charging, that is, the greater the potential charging pressure of the charging station to be adjusted, which means that the charging station to be adjusted has a greater demand for vehicle charging scheduling under the current time-sharing period.

[0038] Preferably, in some possible implementations of the embodiments of the present invention, the process of acquiring the charging attraction degree includes: Within the preset geographic neighborhood of the charging station to be adjusted, the route length of the shortest driving route from each vehicle to be charged to the charging station to be adjusted in the current time-sharing period is used as the initial charging distance from each vehicle to be charged to the charging station to be adjusted; the charging service fee of the charging station to be adjusted in the current time-sharing period is counted. In a specific implementation of an embodiment of the present invention, the preset geographic neighborhood range is set to a circular area corresponding to a radius of two kilometers with the target as the center. The size of the preset geographic neighborhood range can be adjusted according to the specific implementation environment, and no further details are given here. And in a specific implementation of an embodiment of the present invention, the shortest driving route from each vehicle to be charged to the charging station to be adjusted in the current time-sharing period can be determined by navigation software or GPS, so as to determine the corresponding initial charging distance. It should be noted that in order to make the analysis of the vehicle to be charged more reasonable in this application, in a specific implementation of an embodiment of the present invention, the vehicles to be charged are all electric vehicles outside the charging station, the percentage of the remaining power is less than the preset charging threshold and have been started, so that the analyzed vehicles to be charged have a reasonable willingness to charge, so that the subsequent analysis is more accurate, and the preset charging threshold is set to 0.2, which can be adjusted according to the specific implementation environment.

[0039] The distance weight of each vehicle to be charged in the current time-sharing period is determined according to the remaining power of each vehicle to be charged in the current time-sharing period; the service fee weight is determined according to the distance weight, and the sum of the distance weight and the service fee weight is a real number 1. Considering that the vehicles to be charged will pay more attention to the charging station that is closer when the power is low, the distance weight and the service fee weight are set to adjust the weight according to the specific implementation environment, and in order to ensure the uniformity of the analysis results, the sum of the distance weight and the service fee weight is set to the real number 1. Therefore, after determining the distance weight, the required service fee weight can be determined by subtracting the distance weight from the real number 1.

[0040] Preferably, in some possible implementations of the embodiments of the present invention, the process of obtaining the distance weight includes: As for the distance weight, the larger the distance weight, the greater the distance requirement of the vehicle to be charged, that is, the closer the charging station is needed; and the less the remaining power of the vehicle to be charged, the greater the owner's anxiety about electricity consumption will be, and the higher the demand for a charging station close to the vehicle; therefore, the less the remaining power of each vehicle to be charged in the current time-sharing period, the greater the corresponding distance weight should be; therefore, the remaining power of each vehicle to be charged in the current time-sharing period is further normalized with a negative correlation to determine the distance weight of each vehicle to be charged in the current time-sharing period.

[0041] In a specific implementation of the embodiment of the present invention, the process of obtaining the distance weight is expressed by the formula: ;in, The vehicle to be charged in the current time period The distance weight of The vehicle to be charged in the current time period The remaining power; It is a linear normalization function. The implementer can adjust the normalization method according to the specific implementation environment.

[0042] After determining the distance weight and service fee weight, the corresponding parameters are further weighted to analyze the charging attraction degree more accurately. Specifically, the distance attraction degree of each to-be-charged vehicle to the to-be-adjusted charging station in the current time-sharing period is determined according to the product of the negative correlation mapping value of the initial charging distance and the distance weight; the service fee attraction degree of each to-be-charged vehicle to the to-be-adjusted charging station in the current time-sharing period is determined according to the product of the negative correlation mapping value of the charging service fee and the service fee weight. The smaller the initial charging distance, the smaller the time cost and space cost of the to-be-charged vehicle to the corresponding to-be-adjusted charging station for charging, and the greater the corresponding attraction degree; therefore, when weighting by the distance weight, the initial charging distance needs to be negatively mapped first; similarly, the lower the charging service fee, the smaller the cost of the to-be-charged vehicle to the corresponding to-be-adjusted charging station for charging, and the greater the corresponding attraction degree; therefore, when weighting by the distance weight, the charging service fee needs to be negatively mapped first.

[0043] The distance attraction degree and the service fee attraction degree both represent the ability of the charging station to be adjusted to attract the charging vehicles. Therefore, the distance attraction degree and the service fee attraction degree are further combined, and the initial charging attraction degree of each charging vehicle to be charged to the charging station to be adjusted in the current time-sharing period is determined according to the sum of the distance attraction degree and the service fee attraction degree. It should be noted that in addition to the sum, the implementer can also determine the initial charging attraction degree according to the distance attraction degree and the service fee attraction degree by other methods, such as the normalized value of the product, etc., which will not be further elaborated here.

[0044] In a specific implementation of the embodiment of the present invention, the process of obtaining the initial charging attraction degree is expressed by the formula: ;in, The vehicle to be charged in the current time-sharing period Go to the charging station to be adjusted The initial charge attraction level; The vehicle to be charged in the current time-sharing period The distance weight of The vehicle to be charged in the current time-sharing period Go to the charging station to be adjusted Initial charging distance; It is a linear normalization function. The implementer can adjust the normalization method according to the specific implementation environment. The vehicle to be charged in the current time-sharing period Go to the charging station to be adjusted The negative correlation mapping value of the initial charging distance; The vehicle to be charged in the current time-sharing period Go to the charging station to be adjusted The degree of distance attraction; The charging station to be adjusted in the current time-sharing period Charging service fee; The charging station to be adjusted in the current time-sharing period The negative correlation mapping value of the charging service fee; The vehicle to be charged in the current time-sharing period The weight of the service fee; The vehicle to be charged in the current time-sharing period Go to the charging station to be adjusted attractiveness of service fees.

[0045] Preferably, in some possible implementations of the embodiments of the present invention, the process of obtaining the attraction control weight includes: Within the preset geographic neighborhood of each vehicle to be charged in the current time-sharing period, calculate the charging attraction degree of all charging stations for each vehicle to be charged; in the current time-sharing period, take the charging station corresponding to the maximum charging attraction degree of each vehicle to be charged as the attraction charging station for each vehicle to be charged. Within the preset geographic neighborhood of the charging station to be adjusted, take the number of vehicles that use the charging station to be adjusted as the attraction charging station in the current time-sharing period as the reference attraction number of the charging station to be adjusted. The larger the reference attraction number, the more vehicles to be charged that use the charging station to be adjusted as the preferred charging station at the current moment within the preset geographic neighborhood of the charging station to be adjusted, the stronger the willingness of the vehicles to be charged to go to the charging station to be adjusted for charging, that is, the greater the potential charging pressure of the charging station to be adjusted, and the greater the demand for vehicle charging scheduling.

[0046] Within the preset geographic neighborhood of the charging station to be adjusted, the average value of the charging attraction of the charging station to be adjusted to all vehicles to be charged in the current time-sharing period is taken as the overall attraction capacity of the charging station to be adjusted. The greater the overall attraction capacity, the stronger the attraction capacity of the charging station to be adjusted to each vehicle to be charged within the preset geographic neighborhood, and the greater the possibility that the charging station to be adjusted will be selected for charging, that is, the greater the potential charging pressure of the charging station to be adjusted, and therefore the greater the demand for vehicle charging scheduling.

[0047] Taking into account that both the reference attraction quantity and the overall attraction capacity can represent the vehicle's demand for charging scheduling, the reference attraction quantity and the overall attraction capacity are further combined, and the attraction control weight of the charging station to be adjusted in the current time-sharing period is determined according to the product of the reference attraction quantity and the overall attraction capacity; when the attraction control weight is larger, the charging station to be adjusted needs vehicle charging scheduling more, that is, the higher the demand for dispatching vehicles to other charging stations or other time-sharing periods.

[0048] In a specific implementation of the embodiment of the present invention, the process of obtaining the attraction control weight includes: ;in, The charging station to be adjusted in the current time period The attractiveness regulation weight; The charging station to be adjusted in the current time-sharing period The average value of the charging attraction of all vehicles to be charged, that is, the charging stations to be adjusted in the current time period Overall attractiveness; The charging station to be adjusted in the current time-sharing period To attract the number of vehicles to the charging station, that is, the charging station to be adjusted The reference attraction quantity.

[0049] Step S103: In the area where the charging station to be adjusted is located in the current time-sharing period, according to the uneven distribution of the number of vehicles queuing for charging at all charging stations and the saturation of the number of vehicles queuing for charging at the charging station to be adjusted, determine the queue control weight of the charging station to be adjusted in the current time-sharing period.

[0050] For the area where the charging station to be adjusted is located, the more uneven the number of vehicles queuing for charging in each charging station in the current time-sharing period, the more the area needs to promote vehicle scheduling in terms of maintaining the stable operation of each charging station and the stable power supply pressure; and the more vehicles queuing for charging at the charging station to be adjusted in the current time-sharing period, the closer the charging vehicles at the charging station to be adjusted are to saturation, and the greater the corresponding demand for scheduling to other charging stations or other time-sharing periods for charging; therefore, according to the uneven distribution of the number of vehicles queuing for charging at all charging stations and the saturation of the number of vehicles queuing for charging at the charging station to be adjusted, the demand for vehicle charging scheduling is further characterized by the obtained queuing control weight.

[0051] Preferably, in some possible implementations of the embodiments of the present invention, the process of obtaining the queue control weight includes: Within the preset geographic neighborhood of the charging station to be adjusted in the current time-sharing period, the variance of the number of vehicles queuing for charging in all charging stations is used as the degree of uneven vehicle queuing. For any set of data, the larger the variance, the more discrete the set of data, that is, the more uneven the set of data; therefore, the greater the degree of uneven vehicle queuing obtained by the variance, the more uneven the number of vehicles queuing for charging in each charging station in the current time-sharing period, and the more the region needs to promote vehicle scheduling in terms of maintaining the stable operation of each charging station and the stable power supply pressure.

[0052] The average number of vehicles queuing for charging in all charging stations in the current time-sharing period is taken as the reference queue number; the difference between the number of vehicles queuing for charging in the charging station to be adjusted in the current time-sharing period and the reference queue number is normalized to determine the charging saturation degree of the charging station to be adjusted in the current time-sharing period. The reference queue number represents the overall characteristics of the numerical size of a set of data. The greater the difference between the number of vehicles queuing for charging in the charging station to be adjusted in the current time-sharing period and the reference queue number, the greater the charging saturation degree, indicating that the number of vehicles queuing for charging in the charging station to be adjusted is relatively more, and the corresponding queuing vehicles are relatively more saturated, and the greater the need to dispatch vehicles that want to go to the charging station to be adjusted to charge to other charging stations.

[0053] The unevenness of vehicle queues represents the overall demand for charging vehicle dispatch in the area where the charging station to be adjusted is located, while the charging saturation represents the demand for charging vehicle dispatch at the charging station to be adjusted; therefore, the greater the unevenness of vehicle queues and the charging saturation, the more the charging station to be adjusted needs to dispatch vehicles for charging, that is, the higher the demand for dispatching vehicles to other charging stations or other time-sharing periods. Further, according to the unevenness of vehicle queues and the charging saturation, the queue control weight of the charging station to be adjusted in the current time-sharing period is determined; the unevenness of vehicle queues and the charging saturation are both positively correlated with the queue control weight; so that the larger the queue control weight, the higher the demand for dispatching vehicles to other charging stations or other time-sharing periods.

[0054] Preferably, in some possible implementations of the embodiments of the present invention, the process of determining the queue control weight of the charging station to be adjusted in the current time-sharing period according to the unevenness of the vehicle queues and the charging saturation level includes: The product of the unevenness of vehicle queues and the charging saturation is used as the queue control weight of the charging station to be adjusted in the current time-sharing period. It should be noted that in addition to the product, the implementer can also calculate the queue control weight by other methods according to the correlation, such as the normalized value of the mean and the sum, which will not be further elaborated here.

[0055] In a specific implementation of the embodiment of the present invention, the process of obtaining the queue control weight is expressed by the formula: ; The charging station to be adjusted in the current time period The queue control weight of The charging station to be adjusted in the current time period The number of vehicles in the charging queue; For charging stations to be adjusted The average number of vehicles queuing for charging at all charging stations in the current time period within the preset geographical neighborhood, that is, the number of charging stations to be adjusted in the current time-sharing period The number of reference queues; It is a linear normalization function. The implementer can adjust the normalization method according to the specific implementation environment. The charging station to be adjusted in the current time-sharing period The charging saturation level; For charging stations to be adjusted The variance of the number of vehicles queuing for charging at all charging stations in the current time period within the preset geographical neighborhood, that is, the number of charging stations to be adjusted in the current time-sharing period The degree of unevenness of vehicle queues.

[0056] Step S104: Determine the unit price control weight of the charging station to be adjusted in the current time-sharing period according to the attraction control weight and the queue control weight; adjust the preliminary controlled charging unit price according to the unit price control weight to determine the charging unit price to be adjusted in the current time-sharing period; adjust the operating strategy of the charging station to be adjusted according to the charging unit price to be adjusted.

[0057] The charging station can only dispatch vehicles passively and cannot actively command or require car owners to choose other charging stations. Therefore, the charging flow is usually increased or decreased by adjusting the charging unit price to indirectly dispatch vehicle charging. Both the attraction control weight and the queue control weight can characterize the demand for vehicle dispatch to a certain extent. Therefore, the unit price control weight that characterizes the adjustment range of the charging unit price is finally determined by combining the attraction control weight and the queue control weight. The preliminary controlled charging unit price is adjusted in combination with the unit price control weight, and a more accurate charging unit price to be adjusted corresponding to the charging station to be adjusted in the current time-sharing period is adaptively determined. This makes the ability to control charging vehicles stronger and more reasonable, solves the problem that the existing technology uses time-sharing electricity prices to set different fixed charging unit prices for each time-sharing period, and has poor ability to control charging vehicles, and improves the robustness of the charging station operation strategy.

[0058] Preferably, in some possible implementations of the embodiments of the present invention, the process of obtaining the unit price control weight includes: As the attraction control weight increases, the queue control weight increases, the charging station to be adjusted needs to dispatch vehicles for charging more, that is, the demand for dispatching vehicles to other charging stations or other time-sharing periods is higher; and the charging station dispatches vehicles by regulating the charging unit price. The higher the charging unit price, the more likely the owners of the vehicles to be charged will go to other charging stations or other time-sharing periods to charge after considering the charging cost; therefore, the product of the attraction control weight and the queue control weight is further multiplied as the unit price control weight of the charging station to be adjusted in the current time-sharing period; so that the larger the unit price control weight, the higher the adjusted charging unit price.

[0059] Preferably, in some possible implementations of the embodiments of the present invention, the process of obtaining the charging unit price to be regulated includes: The product of the positive correlation mapping value of the unit price control weight and the preliminary controlled charging unit price is used as the charging unit price to be adjusted for the charging station to be adjusted in the current time-sharing period. Since the larger the unit price control weight, the higher the adjusted charging unit price should be, the charging unit price to be adjusted is determined by directly combining the preliminary controlled charging unit price after the positive correlation mapping of the unit price control weight. The purpose of positive correlation mapping of the unit price control weight is to give the preliminary controlled charging unit price an appropriate control weight value. In a specific implementation of an embodiment of the present invention, the process of obtaining the charging unit price to be adjusted is expressed by the formula: ;in, The charging station to be adjusted in the current time period The charging unit price to be regulated; The charging station to be adjusted in the current time period The initial regulation of charging unit price; The charging station to be adjusted in the current time period The attractiveness regulation weight; The charging station to be adjusted in the current time period The queue control weight of The charging station to be adjusted in the current time period The unit price control weight; It is a linear normalization function. The implementer can adjust the normalization method according to the specific implementation environment. To preset the second positive correlation mapping parameter, the embodiment of the present invention is set to 0.6, which can be adjusted according to the specific implementation environment; The charging station to be adjusted in the current time period The positive correlation mapping value of the unit price control weight is used to perform positive correlation mapping with the help of the preset second positive correlation mapping parameter and the normalization function, so that the preliminary controlled charging unit price can be flexibly adjusted reasonably.

[0060] Preferably, in some possible implementations of the embodiments of the present invention, the process of adjusting the charging station operation strategy to be adjusted according to the charging unit price to be adjusted includes: Since the data used in the embodiment of the present invention to analyze the current time-sharing period is the data corresponding to 5 minutes before the start of the current time-sharing period, the charging unit price that should be adjusted for the current time-sharing period has been calculated 5 minutes before the current time-sharing period. Therefore, the charging unit price of the charging station to be adjusted in the current time-sharing period is finally adjusted to the charging unit price to be regulated.

[0061] In summary, a charging station operation strategy adjustment method determines a preliminary adjustment charging unit price based on the preset charging unit price according to the overall number of charging vehicles in the current time-sharing period in historical data; then determines the charging attraction degree that characterizes the charging willingness of each to-be-charged vehicle to the charging station to be adjusted in terms of distance and service fee; then characterizes the demand for charging scheduling of charging vehicles in the dimension of attracting vehicles to charge at the charging station to be adjusted according to the attraction control weight determined by the charging attraction degree; then determines the queue control weight according to the characteristics that the more uneven the number of charging vehicles queuing for charging at each charging station and the more saturated the number of charging vehicles queuing for charging at the charging station to be adjusted, the greater the demand for vehicle charging scheduling; thereby comprehensively determining the unit price control weight that characterizes the demand for vehicle charging scheduling by combining the attraction control weight and the queue control weight; finally, the preliminary adjustment charging unit price is adjusted according to the unit price control weight, so that the charging willingness of the owner is changed in the price dimension according to the obtained charging unit price to be regulated, so that the ability to regulate the charging vehicle is stronger and more reasonable, which solves the problem that the method of setting different fixed charging unit prices for each time-sharing period in the prior art using time-sharing electricity prices has poor ability to regulate charging vehicles, and improves the robustness of the charging station operation strategy.
