Description

Technical Field

[0001] The present invention relates to the technical field of charging and discharging pile placement, and in particular to a method, device, electronic equipment and storage medium for selecting a charging and discharging pile placement address. Background Art

[0002] With the rapid development of the electric vehicle market, the demand for charging infrastructure is increasing. Among them, the vehicle to grid (V2G) charging and discharging pile, as a new type of charging facility, can not only charge electric vehicles, but also transmit the battery energy of electric vehicles back to the grid, realizing bidirectional charging and discharging of electric vehicles and the grid. For the grid, V2G technology can achieve the effects of peak-shaving, dynamic capacity increase, load-side response and emergency power supply of the grid load, thereby improving the stability of the grid. For electric car owners, they can absorb electricity when the grid load is low and the electricity price is low; release electricity when the grid load is high and the electricity price is high, sell the electricity in the electric car to the grid, earn the difference and obtain economic benefits. For car companies, V2G technology enables users to effectively reduce the cost of using electric vehicles. In an emergency, V2G technology can also be used to use electric vehicles with power output function as emergency power sources, which invisibly increases the use of electric vehicles and promotes the production and sales of electric vehicles. Therefore, V2G is a win-win situation for the grid, electric car owners and car companies.

[0003] However, there are few existing charging and discharging piles that support V2G technology. If users want to discharge electricity to the grid during peak hours, they may need to drive a long way to reach a charging pile that meets the discharge conditions, which hinders users' enthusiasm and willingness to participate in V2G technology. At present, the site selection method of charging and discharging piles is mainly based on human experience and judgment. Most of them are installed in parks or customer-specified locations, ignoring the gathering, parking and battery status of vehicles, resulting in unreasonable distribution of charging and discharging piles and low utilization of charging and discharging piles.

In addition, components, features, and elements with the same name in different embodiments of the present application may have the same meaning or different meanings, and their specific meanings need to be determined by their explanation in the specific embodiment or further combined with the context of the specific embodiment.

[0060] See also Figure 1 , is a flow chart of a method for selecting a charging and discharging pile delivery address provided in an embodiment of the present application. The method for selecting a charging and discharging pile delivery address can be executed by a device for selecting a charging and discharging pile delivery address provided in an embodiment of the present application. The device can be implemented in software and / or hardware, such as a server, a computer, a processor and other electronic devices. In this embodiment, the execution subject of the method for selecting a charging and discharging pile delivery address is a processor of a vehicle-mounted terminal as an example. The method for selecting a charging and discharging pile delivery address provided in this embodiment includes:

[0061] Step S1, obtaining the operation data of the vehicle, and obtaining the travel information of the vehicle according to the operation data;

[0062] Step S2, extracting the stop address of the vehicle from the trip information;

[0063] Step S3, performing DBSCAN clustering on the stay address, and selecting the clustering result that meets the preset clustering condition as the target address for the placement of the charging and discharging pile.

[0064] Here, the vehicle's operating data can come from the vehicle's on-board navigation system, battery management system, on-board communication module, on-board data recorder and other on-board devices. These data can reflect the vehicle's driving data and power data. The vehicle's navigation data can also be obtained from the vehicle's operating data. The time and place of the vehicle in the use state and the time and place of the vehicle in the non-use state can be known through the navigation data. The location of the vehicle in the non-use state is the vehicle's stop address. By extracting the vehicle's stop address from the vehicle's operating data, it can be ensured that these stop addresses are accurate and can reflect the vehicle's real stop address. By performing DBSCAN clustering on the real vehicle stop address to obtain the target address for placing the charging and discharging pile, the target location for placing the charging and discharging pile is the actual location where the vehicle is parked, thereby making the layout of the charging and discharging pile more consistent with the actual use of the vehicle, improving the use efficiency of the charging and discharging pile, and promoting the promotion and use of the electric vehicle to grid (Vehicle to Grid, V2G) mode.

[0065] In some embodiments of the present invention, the step of extracting the stop address of the vehicle from the trip information includes:

[0066] The operation data is preprocessed, and a target vehicle that meets a preset clustering condition is selected based on the preprocessed operation data; the stop address of the vehicle is extracted according to the preprocessed operation data of the target vehicle; the preset clustering condition includes: the parking time of the vehicle within a preset time period meets the preset time period and the remaining power of the vehicle battery when parked meets the preset remaining power threshold.

[0067] It is understandable that the raw operating data directly obtained may be missing, duplicated, and abnormal, and the operating data from different sources may have problems such as inconsistent formats or data types. By preprocessing the raw operating data, these operating data can be identified and processed to ensure the consistency of the operating data format and type, improve the quality and credibility of the operating data, and ensure the practicality of the clustering results.

[0068] Here, the preset time period in the preset clustering condition can be a peak period of vehicle use, such as rush hour, weekends, etc. The specific time period can be set according to the specific situation. The preset parking time can be 5 hours, 6 hours, etc. The preset remaining power threshold can be 50%, 60%, 70% of the vehicle battery capacity, etc., which can be set according to the specific situation. When the vehicle meets the preset clustering conditions, it means that the owner of the vehicle does not have a high demand for the vehicle, and the vehicle battery has enough power to be discharged.

[0069] In some embodiments of the present invention, the method for selecting the charging and discharging pile placement address also includes: setting a first reference itinerary and a second reference itinerary in the itinerary information; and calculating the parking time of the vehicle based on the time difference between the end time of the first reference itinerary and the start time of the second reference itinerary.

[0070] Here, the first reference trip and the second reference trip can be any two adjacent trips extracted from the trip information, and the time difference between the end and the start of the two adjacent trips is used to represent the parking time of the vehicle. In this way, the parking locations of vehicles that have been parked for a long time within a preset time period and have a high battery remaining power can be screened out, thereby improving the accuracy of the target address selection of the charging and discharging station.

[0071] For example, if a vehicle finishes a trip at 10 a.m. and starts the next trip at 18:00 p.m. on the same day, it can be considered that the vehicle has been parked at the location where it was parked at 10 a.m. for 8 hours.

[0072] In some embodiments of the present invention, before performing DBSCAN clustering on the stay address, the method further includes: acquiring longitude data and latitude data of the stay address, and converting the longitude data and the latitude data into radians.

[0073] Understandably, before performing DBSCAN clustering on the stay address, the longitude and latitude are converted to radians because the earth is a sphere, and longitude and latitude use angles to represent positions. When performing distance calculations or cluster analysis on a sphere, directly using angles may lead to calculation errors because the distance of the angle does not directly correspond to the actual distance on the surface. Specifically, the shape of the earth is approximately an ellipsoid, and the longitude and latitude represent the position on the surface of the earth, but in spherical geometry, the calculation of the true distance needs to consider the influence of the curvature of the earth. The radian system measures the arc length on the sphere, not a simple angle, so it is more suitable for distance calculation and cluster analysis on the surface of the earth. After converting the longitude and latitude to the radian system, the error of distance calculation can be reduced, and a more accurate clustering result can be obtained, thereby improving the accuracy of the selection of charging and discharging station addresses.

[0074] In some embodiments of the present invention, performing DBSCAN clustering on the stay address and selecting a clustering result that meets a preset clustering condition as a target address for charging and discharging pile deployment includes: performing DBSCAN clustering on the longitude data and latitude data in the radian system;

[0075] Determine the stay address corresponding to the preset cluster in the clustering results that meet the preset clustering condition as the target address for the charging and discharging pile deployment;

[0076] The preset condition includes: the silhouette coefficient meets the preset coefficient value.

[0077] It can be understood that the silhouette coefficient can be understood as an evaluation index of the clustering effect. Its actual meaning is the compactness of samples in the cluster, and the greater the distance between clusters, the better the clustering effect. Specifically, the value of the silhouette coefficient is in the range of [-1,1]. The closer it is to 1, the higher the density of samples in the cluster and the separation between clusters, and the better the clustering effect.

[0078] In some embodiments of the present invention, after performing DBSCAN clustering on the stop addresses in the radian system, the method further includes: adjusting the scanning radius and the minimum number of samples of the DBSCAN clustering by a grid parameter adjustment method, and calculating the silhouette coefficients corresponding to different scanning radii and different minimum numbers of samples.

[0079] It is understandable that adjusting the scan radius and the minimum number of samples can significantly affect the results of DBSCAN clustering. The scan radius and the minimum number of samples directly affect the clustering density of DBSCAN. Too small a scan radius or too small a minimum number of samples may lead to overfitting (noise points are treated as independent classes); while too large a scan radius or too large a minimum number of samples may lead to underfitting (most points are treated as noise). By adjusting the parameters, a balance can be found between overfitting and underfitting to obtain appropriate clustering results. As mentioned above, by adjusting the parameters through grid search, the optimal parameter combination can be found to optimize the clustering effect.

[0080] In some embodiments of the present invention, the selecting of the clustering result satisfying the preset clustering condition as the target address for the placement of the charging and discharging piles further includes: obtaining the center position of the stay address corresponding to the preset number of clusters, and determining whether to determine the center position as the target address for the placement of the charging and discharging piles in combination with the actual environment of the center position and the placement of the charging and discharging piles within a preset range of the center position.

[0081] Understandably, after determining the center position corresponding to each cluster, it is necessary to examine the actual environment in which these center positions are located. This includes factors such as the surrounding geographical features, urban facilities, and traffic conditions. At the same time, it is necessary to understand the distribution of existing charging and discharging piles in the areas where these center positions are located, in order to assess whether the center position of each cluster is suitable as a new charging and discharging pile placement location. In this way, the actual geographical conditions of the vehicle gathering area and the layout of the existing charging and discharging facilities are taken into account, and the best charging and discharging pile placement location can be selected to meet the charging and discharging needs.

[0082] In some embodiments of the present invention, the method for selecting the charging and discharging pile placement address further includes:

[0083] The layout of the charging and discharging piles around the target address is displayed on a map, the usage of the charging and discharging piles is monitored, and user feedback is received; based on the usage and the user feedback, the number of the charging and discharging piles is adjusted.

[0084] Here, the map can intuitively display the layout of the charging and discharging piles around the target address. Combined with the usage and user feedback, it can be judged whether the layout of the charging and discharging piles at this location is reasonable. According to the usage, the number of charging and discharging piles can be modified, or the placement address can be changed. In this way, the flexibility of the charging and discharging pile site selection can be improved.

[0085] The method for selecting the charging and discharging pile placement address provided by the embodiment of the present invention obtains the vehicle's travel data and power data from the vehicle's operation information, performs DBSCAN clustering on the parking addresses that meet the stay time and power requirements, thereby selecting the parking addresses where the vehicle is parked for a long time and the battery power of the vehicle meets the charging and discharging requirements when parked, and uses the selected parking addresses as the target addresses for placing the charging and discharging piles. In this way, the charging and discharging piles can be reasonably placed according to the user's car usage habits, thereby improving the utilization rate of the charging and discharging piles.
