[0033] In order to make the purpose, technical solution and advantages of the present invention clearer and more specific, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0034] The following describes the charging device construction planning method, device, terminal and storage medium of the embodiment of the present application with reference to the accompanying drawings. In view of the problem mentioned in the above background technology that when constructing charging devices for charging stations, the vehicle behavior of the charging station is not considered, which easily leads to too few charging devices being built to meet the vehicle charging needs, or too many charging devices being built, resulting in waste of resources, and thus leading to unreasonable construction of charging devices in charging stations, the present application provides a charging device construction planning method, in which the actual parking information of each parking space in the target charging station in the previous period is obtained, and the parking prediction information of each parking space in the target charging station in the next period is simulated in a pre-constructed simulation model according to the actual parking information; several charging device construction scenarios are simulated to determine the investment costs corresponding to the several charging device construction scenarios, and the user satisfaction corresponding to the several charging device construction scenarios is determined based on the parking prediction information; the target charging device construction scenario is determined in the several charging device construction scenarios according to the investment cost and user satisfaction, and the charging construction information corresponding to the target charging device construction scenario is used as the charging device construction planning result. This application simulates the parking prediction information in the target charging station in the next period, takes into account the vehicle behavior in the charging station, and determines the charging device construction planning results based on user satisfaction and investment cost, thereby improving the rationality of the charging device construction.

[0035] Specifically, Figure 1 A schematic flow chart of a charging device construction planning method provided in an embodiment of the present application.

[0036] like Figure 1 As shown, the charging device construction planning method described in the embodiment of the present invention includes:

[0037] Step S100: Acquire actual parking information of each parking space in the target charging station in the previous period, and simulate in a pre-built simulation model according to the actual parking information to obtain parking prediction information of each parking space in the target charging station in the next period.

[0038] Specifically, when constructing the simulation model, historical data and structural features of the target charging station can be collected, such as the average parking time of vehicles parked at the station, the average charging order time of historical electric vehicles, the probability of parking vehicles in each parking space, and the type of parked vehicles (traditional fuel vehicles or electric vehicles). The structural features are: Where T ix represents the historical average parking time of electric vehicle users; T ic represents the expected charging time for electric vehicle users; is the parking probability parameter of each parking space, representing the probability that the parking space is selected and parked by each car entering the station; is the distance from each parking space to the parking lot exit, which is based on the plane structure design of the station. The simulation is carried out based on these data.

[0039] In the embodiment of the present application, the actual parking information includes: the total number of electric vehicles that entered the target charging station in the previous period and the parking positions of the electric vehicles in the target charging station in the previous period.

[0040] Specifically, an embodiment of the present application is a rolling planning method. For example, taking one month as a time period, the actual parking information of each parking space in the previous time period is used to predict the parking prediction information of each parking space in the next time period, and then a decision on the construction of charging devices for different parking spaces in the next time period is made.

[0041] The embodiment of the present application improves the rationality of construction by continuously using real-time information to make decisions on the construction of charging devices for each parking space in the next stage.

[0042] like Figure 1 As shown, the charging device construction planning method described in this embodiment also includes:

[0043] Step S200, simulating several charging device construction scenarios, determining the investment costs corresponding to the several charging device construction scenarios, and determining the user satisfaction corresponding to the several charging device construction scenarios based on the parking prediction information.

[0044] In an embodiment of the present application, the charging construction information corresponding to the charging device construction scenario includes: the number of charging devices to be constructed and the target parking space locations for constructing the charging devices; the maximum load current corresponding to each of the charging device construction scenarios is less than or equal to the maximum thermal capacity current that the power system connected to the target charging station can withstand.

[0045] Specifically, assuming that several charging devices are built at the target charging station, as well as the parking spaces where each charging device is located, to form several charging device construction scenarios, the investment cost and user satisfaction required for construction according to each charging device construction scenario can be calculated. The maximum load current required for each charging device construction scenario cannot exceed the maximum thermal capacity current that the power system connected to the charging station can withstand, that is:

[0046]

[0047] In the formula, represents the maximum load current required for each charging device construction scenario, t represents the unit time, T represents the time period, It indicates the maximum thermal capacity current that the power system connected to the charging station can withstand. A means that the charging device is connected to phase A of the three-phase circuit laid in the charging station. B means that the charging device is connected to phase B of the three-phase circuit laid in the charging station. C means that the charging device is connected to phase C of the three-phase circuit laid in the charging station.

[0048] The embodiment of the present application simulates the number of parking spaces to be built and the locations of charging devices to be built, and then calculates user satisfaction and investment costs, so as to select a construction scenario based on user satisfaction and investment costs.

[0049] In one embodiment of the present application, the parking prediction information includes: the total number of electric vehicles that will enter the target charging station in the next period and the parking positions of the electric vehicles in the target charging station in the next period. The step S200 of "determining the user satisfaction corresponding to several charging device construction scenarios based on the parking prediction information" specifically includes:

[0050] Based on the parking positions of electric vehicles in the target charging station in the next period, determine the number of target electric vehicles parked in the parking spaces corresponding to the target parking spaces in each charging device construction scenario;

[0051] According to the target number of electric vehicles and the total number of electric vehicles that will enter the target charging station in the next period, the user satisfaction under each charging device construction scenario is obtained.

[0052] In an embodiment of the present application, based on the target number of electric vehicles and the total number of electric vehicles that will enter the target charging station in the next time period, the user satisfaction level under each charging device construction scenario is obtained. Specifically, the ratio of the target number of electric vehicles under each charging device construction scenario to the total number of electric vehicles that will enter the target charging station in the next time period is calculated to obtain the user satisfaction level under each charging device construction scenario.

[0053] Specifically, the calculation formula for user satisfaction is:

[0054]

[0055] in, Indicates the number of target electric vehicles parked in the parking space corresponding to the target parking space position; Represents the total number of electric vehicles entering the target charging station.

[0056] The target number of electric vehicles parked in parking spaces corresponding to the target parking spaces and the total number of electric vehicles entering the target charging station are determined based on parking prediction information obtained by simulation of the simulation model.

[0057] Specifically, the constructed simulation model is as follows:

[0058]

[0059] Where n is the parking space number, d is the owner number, It represents the decision matrix of the car owner. For each electric vehicle that enters, its score for each parking space can be generated to form a matrix of the number of parking spaces to simulate the choice of the car owner. The parking space with the highest score will become the parking space selected by the car owner d, recorded as position i. When the car owner d selects position i, the next car owner d+1 cannot choose this position repeatedly (the score is recorded as 0) until the expected parking time of the car owner d is reached. (Based on the historical average parking time T ix As the set value), d leaves the position, and the position becomes available again and is included in the decision matrix of the next vehicle owner entering; It is the status matrix of each location in the charging station, recording whether there are electric vehicles parked. is the parking probability parameter of each parking space, which represents the probability that the parking space is selected and parked by each car entering the station, and is obtained from the historical parking data of each parking space in the station; is the coefficient of the surrounding parking space occupancy of each parking space when the vehicle enters t, expressed as a score. When there are vehicles parked around parking space n, it will increase the difficulty for car owner d to park in the parking space, thus reducing the car owner's score for the parking space. That is, if there are no vehicles parked in the adjacent parking spaces of parking space n, the score is the highest. If there are vehicles parked on one side of parking space n, the score is medium. If there are vehicles parked on both sides of parking space n, the score is low. is the distance from each parking space to the parking lot exit. * The number is equal to the parking space that car owner d finally parked. * If the number of the parking space where the charging device is to be built coincides with that of the target parking space, the charging vehicle is recorded as satisfied. Plus one. t represents unit time. For electric car owner d, the location where the charging pile is installed will be more attractive to the owner to park. This preference is reflected in middle.

[0060] The embodiment of the present application obtains user satisfaction under each charging device construction scenario by calculating the ratio of the target number of electric vehicles under each charging device construction scenario to the total number of electric vehicles that will enter the target charging station in the next period of time. That is, user satisfaction is defined according to the ratio of the number of parking spaces for charging devices to be constructed to the total number of electric vehicles, thereby realizing the construction of charging devices based on vehicle behavior and improving rationality.

[0061] In the embodiment of the present application, the investment cost includes: the charging device expansion cost, the charging device purchase cost, the line laying cost of the parking space corresponding to the target parking space position, and the charging device maintenance cost.

[0062] Specifically, the hardware structure data such as the transformer model, line layout, and distance from the parking space to the parking lot exit of the station are obtained to build an investment cost model for the internal spatial location coupling of the station. The station operation cost caused by the charging load can be expressed as:

[0063]

[0064] Among them, Cost mob represents the investment cost, The cost of expanding the power system is proportional to the number of charging devices to be added. Indicates the purchase cost of charging devices, which is proportional to the number of new charging devices to be added. The line laying cost of the parking space corresponding to the target parking space is related to the number and location of the additional charging devices to be installed. represents the maintenance cost of the charging device, which is proportional to the total number of charging devices. Specifically, It includes the line laying cost caused by the different locations of parking spaces from electrical connection points (such as transformers and busbars).

[0065] The embodiment of the present application takes into account the expansion, purchase and maintenance costs of the charging device, as well as the cost of laying the line, so that the calculation of the investment cost is more reasonable.

[0066] like Figure 1 As shown, the charging device construction planning method described in this embodiment also includes:

[0067] Step S300: determining a target charging device construction scenario from among the plurality of charging device construction scenarios according to the investment cost and user satisfaction, and using the charging construction information corresponding to the target charging device construction scenario as a charging device construction planning result.

[0068] Specifically, the charging device construction planning results include: the number of charging devices to be built and the target parking space locations for building the charging devices.

[0069] In the embodiment of the present application, the step S300 of “determining a target charging device construction scenario from among the plurality of charging device construction scenarios according to the investment cost and user satisfaction” specifically includes:

[0070] The charging device construction scenarios with user satisfaction greater than a preset threshold are used as the initial screening charging device construction scenarios;

[0071] The initially screened charging device construction scenario with the lowest investment cost is taken as the target charging device construction scenario.

[0072] Specifically, the embodiment of the present application selects a solution with high user satisfaction and low investment cost for construction, so that the construction solution can be applicable to the target charging station.

[0073] The embodiment of the present application no longer constructs charging devices for charging stations all at once, but divides the time periods and performs real-time construction updates. Specifically, the construction plan for the next time period is predicted based on the actual parking information of the previous time period. For example, charging devices are constructed in 50 of the 100 parking spaces in the parking lot. After the next time period, the construction plan for the third time period can be predicted based on the actual parking information of the next time period. If the construction plan for the third time period is updated, different processing plans are used for fixed charging piles and movable shared charging devices.

[0074] Specifically, for fixed charging piles, the expansion construction of charging equipment can continue according to the construction plan of the third period; for movable shared charging devices, expansion construction can be carried out, or the previous movable charging devices can be moved to the parking space currently needed.

[0075] In this way, the embodiments of the present application are based on real-time power data, user interaction and optimized intelligent decision-making, so that charging stations can achieve goals such as high user satisfaction, high charging station operating efficiency, and low power system expansion costs under the large-scale electric vehicle charging demand, thereby achieving a balance among car owners, stations, and power grids.
