[0065] In one embodiment, such as Figure 1 As shown, a method for determining the construction location of a charging station is provided. This embodiment illustrates the application of this method to a terminal. It is understood that this method can also be applied to a server, and further to a system including both a terminal and a server, and implemented through interaction between the terminal and the server. In this embodiment, the method includes the following steps:
[0066] S102. For any candidate construction location of a charging station in the target power supply area, obtain the first charging demand data of the charging service coverage area of the candidate construction location.
[0067] Among them, the power supply area refers to a power supply area with a clear geographical boundary that is powered by a single distribution transformer or a single distribution circuit; the charging demand data refers to quantitative data used to characterize the amount of charging services required for a region or location.
[0068] S104. Perform density clustering on all candidate construction locations in the power supply area to obtain at least one demand hot zone; for all charging service coverage areas of all candidate construction locations in any demand hot zone, obtain the hot zone weight of the demand hot zone based on the first charging demand data of all charging service coverage areas.
[0069] Among them, the demand hot zone refers to the area where charging demand is highly concentrated and the candidate construction sites are densely distributed; the hot zone weight represents the charging demand potential of the corresponding demand hot zone.
[0070] Optionally, the purpose of density clustering is to identify high-demand hotspots based on charging demand at candidate construction locations; the DBSCAN clustering algorithm can be used to perform density clustering on all candidate construction locations in the power supply area, and the clustering radius can be, but is not limited to, [missing information]. The minimum group size can be, but is not limited to, 1. Among them, the DBSCAN clustering algorithm is an algorithm for spatial clustering based on data point density. This is a preset length threshold.
[0071] S106. If the length of the shortest path between any two candidate construction locations is not greater than the first length threshold, obtain the number of first charging piles to be planned at the two candidate construction locations and the number of users that can be served by any one charging pile. For the intersection of the charging service coverage of the two candidate construction locations, obtain the second charging demand data that is not satisfied by the planned charging piles within the intersection.
[0072] Optionally, for any two candidate construction positions i and j, if the following conditions are met... Then, obtain the number of the first charging piles and the number of users that any one charging pile can serve; where, Let be the length of the shortest path between candidate construction locations i and j.
[0073] S108. Based on the number of first charging piles, the number of users that can be served, and the second charging demand data, obtain the collaborative gain value between the two candidate construction locations; wherein, the collaborative gain value is used to characterize that when there is an intersection between the charging service coverage of the two candidate construction locations, the two candidate construction locations meet the additional charging demand.
[0074] Alternatively, the synergistic gain value can be calculated using the following formula:
[0075]
[0076] In the formula, The collaborative gain value between candidate construction positions i and j; and These represent the first number of charging piles to be planned at candidate construction locations i and j, respectively. The scale effect coefficient represents how many users a single charging station can serve. This represents the remaining unmet demand at location k, i.e., the second charging demand data within the intersection that has not been satisfied by the planned charging piles.
[0077] S110. Based on the heat zone weight and the collaborative gain value, determine the target location combination formed by multiple candidate construction locations, and plan charging stations in the power supply area based on the target location combination.
[0078] Optionally, charging stations can be planned in the power supply area based on the location coordinates of each candidate construction location in the target location combination and the number of charging piles to be planned.
[0079] In the above method for determining the construction location of charging stations, for any candidate construction location of a charging station in the target power supply area, the first charging demand data of the charging service coverage area of the candidate construction location is obtained; density clustering is performed on all candidate construction locations in the power supply area to obtain at least one demand hot zone; for all charging service coverage areas of all candidate construction locations in any demand hot zone, the hot zone weight of the demand hot zone is obtained based on the first charging demand data of all charging service coverage areas; and if the length of the shortest path between any two candidate construction locations is not greater than a first length threshold, the first number of charging piles to be planned for the two candidate construction locations is obtained. The system calculates the number of users that can be served by any one charging pile, and obtains the second charging demand data that is not met by the planned charging piles within the intersection of the charging service coverage areas of two candidate construction locations. Based on the number of the first charging piles, the number of users that can be served, and the second charging demand data, it obtains the collaborative gain value between the two candidate construction locations. The collaborative gain value is used to characterize the additional charging demand that the two candidate construction locations meet when there is an intersection between their charging service coverage areas. Based on the heat zone weight and the collaborative gain value, it determines the target location combination formed by multiple candidate construction locations, and plans charging stations in the power supply area based on the target location combination. The method provided in this application obtains demand data of the charging service coverage area of candidate construction sites and identifies demand hotspots based on density clustering. This allows for a precise grasp of the spatial distribution of charging demand, avoiding blind site selection and making the layout of charging stations more aligned with actual user needs. The method introduces a collaborative gain value to quantitatively evaluate the additional demand-satisfying capacity of two candidate construction sites due to overlapping service areas. This prioritizes site combinations that can complement each other and improve overall service efficiency, avoiding resource waste and insufficient coverage. Furthermore, the method determines the target location combination based on hotspot weights and collaborative gains, ensuring priority coverage of high-demand areas while improving overall service capabilities through site collaboration, achieving a balance between local priorities and overall efficiency.
[0080] In some embodiments, such as Figure 2 As shown, the first charging demand data for the charging service coverage area of the candidate construction location is obtained, including:
[0081] S202. Determine any candidate construction location as the first location and any other candidate construction location besides the first location as the second location. For the shortest path between the first location and the second location, if the length of the shortest path is not greater than the second length threshold, determine the second location as the serviceable location of the first location.
[0082] S204. Obtain the third charging demand data of the first location and the fourth charging demand data of any available location of the first location, and determine the sum of the third charging demand data and all the fourth charging demand data as the first charging demand data of the charging service coverage area of the first location.
[0083] Optionally, the set of service locations formed by all serviceable locations of the first location can be represented by the following formula:
[0084]
[0085] In the formula, Let i be the set of service locations, where i is the first location and j is the second location. Let be the length of the shortest path between the first and second positions. This is the second length threshold.
[0086] Optionally, the first position i and the second position j can be the same position.
[0087] Optionally, the first charging demand data can be represented by the following formula:
[0088]
[0089] In the formula, The first charging demand data for the charging service coverage area of the first location i. Data on the fourth charging demand for available locations.
[0090] In this embodiment, by determining the serviceable location based on the shortest path length and summing the demand of the first location itself with the demand of surrounding serviceable locations to obtain the first charging demand data, the overall charging service demand of a single candidate construction location can be quantified more comprehensively and accurately. This provides a real and reliable data foundation for subsequent demand hotspot division and hotspot weight calculation, thereby improving the rationality of determining the construction location of charging stations.
[0091] In some embodiments, obtaining the hot zone weight of a demand hot zone based on the first charging demand data of all charging service coverage areas includes: determining the sum of the first charging demand data of all charging service coverage areas as the fifth charging demand data of the demand hot zone, and obtaining the maximum charging demand data among the fifth charging demand data of all demand hot zones; and determining the first ratio between the fifth charging demand data and the maximum charging demand data of the demand hot zone as the hot zone weight of the demand hot zone.
[0092] Optionally, the heat zone weights of the demand heat zones can be represented by the following formula:
[0093]
[0094] In the formula, For the kth demand hot zone Hot zone weight, The maximum charging demand data is the fifth charging demand data among all demand hot zones.
[0095] In this embodiment, the total demand of the hot zone (the fifth charging demand data) is obtained by summing the demand data of all candidate construction locations within the hot zone. This total demand is then compared with the maximum demand among all hot zones to objectively and quantitatively reflect the demand intensity and importance of each hot zone within the entire power supply area. The hot zone weight, as a standardized dimensionless indicator, provides a clear and comparable basis for decision-making regarding the priority of deploying charging stations and configuring the number of charging piles in high-weight hot zones, which helps to improve the rationality and pertinence of the planning scheme. Based on the hot zone weight, the site layout and scale configuration can prioritize the allocation of limited charging facility resources to the areas with the most concentrated demand, thereby improving resource utilization efficiency and avoiding resource waste or insufficient coverage.
[0096] In some embodiments, determining a target location combination formed by multiple candidate construction locations based on hot zone weights and synergistic gain values includes: sorting all demand hot zones in descending order of hot zone weights, and determining the first demand hot zone in the sorting result as the first demand hot zone; based on the fifth charging demand data of the first demand hot zone, determining at least one candidate construction location in the first demand hot zone as an initial location, and obtaining the number of second charging piles to be planned at at least one initial location; if the number of second charging piles is less than a quantity threshold, for the remaining demand hot zones other than the first demand hot zone in the sorting result, determining the first demand hot zone in the remaining demand hot zones as a new first demand hot zone according to the sorting result, and determining the first difference between the quantity threshold and the number of second charging piles as a new quantity threshold; returning to the step of determining at least one candidate construction location in the first demand hot zone as an initial location based on the fifth charging demand data of the first demand hot zone, and continuing to execute until the number of second charging piles to be planned at the initial location is not less than the quantity threshold; and determining a target location combination formed by multiple candidate construction locations based on all determined initial locations and synergistic gain values.
[0097] Optionally, after sorting all demand hot zones in descending order of their hot zone weights, starting from the demand hot zone with the highest hot zone weight, candidate construction locations are selected as initial locations in each demand hot zone. After selecting an initial location in each demand hot zone, it is determined whether the number of second charging piles to be planned in all the initial locations selected so far is less than a quantity threshold. If it is less, a new candidate construction location is selected as the initial location in the next demand hot zone according to the sorting result. If it is not less, the initial location selection process is stopped.
[0098] In this embodiment, by selecting the initial position according to the heat zone weight from large to small and combining it with synergistic gain optimization, high-demand areas can be prioritized for coverage, the construction scale can be accurately controlled, and the overall service efficiency can be improved, making the planning scheme more reasonable and feasible.
[0099] In some embodiments, based on all determined initial locations and cooperative gain values, determining a target location combination formed by multiple candidate construction locations includes: determining all combinations formed by initial locations as a first initial location combination, and adjusting the number of second charging piles for at least one initial location to be planned for the first initial location combination to obtain at least one second initial location combination; determining at least one third initial location combination; wherein any third initial location combination is formed by at least one candidate construction location combination randomly selected from all demand hot zones; for any initial location combination among the first, second, and third initial location combinations, deleting the initial location combination if the length of the shortest path between any two candidate construction locations in the initial location combination is less than a third length threshold and the two candidate construction locations are located in the same demand hot zone; deleting the initial location combination if the cooperative gain value between any two candidate construction locations in the initial location combination is less than a gain value threshold; determining all remaining initial location combinations that have not been deleted as a first intermediate location combination, and determining the target location combination based on the first intermediate location combination.
[0100] Optionally, after determining the first initial location combination, the number of second charging piles to be planned at at least one initial location can be adjusted to achieve a small random perturbation of the first initial location combination, so as to generate multiple different second initial location combinations and avoid a single initial population; the location coordinates of the candidate construction locations and the number of charging piles to be planned in the third initial location combination are both random.
[0101] Optionally, to reduce invalid or inefficient solution spaces, a collaborative gain matrix is used to assist pruning. Specifically, if the collaborative gain value between any two candidate construction positions i and j in the initial position combination is... If the gain value is less than the threshold, the initial location combination is discarded to avoid wasting resources and overlapping coverage between sites.
[0102] Optionally, if any two candidate construction locations i and j in the initial location combination are located in the same demand hot zone, and the length of the shortest path between candidate construction locations i and j satisfies the following distance constraint, then the initial location combination is eliminated; wherein, the distance constraint is as follows:
[0103]
[0104] In the formula, This is the distance adjustment factor. and These represent the first number of charging piles to be planned at candidate construction locations i and j, respectively.
[0105] Optionally, if any two candidate construction locations i and j in the initial location combination are located in the same demand hot zone, and the fifth charging demand data of that demand hot zone is greater than a threshold... If the shortest path length between candidate construction locations i and j satisfies the following distance constraint, then the initial location combination is eliminated; where, The scale effect coefficient represents how many users a charging station can serve, and the distance constraint is shown in the following formula:
[0106]
[0107] In this embodiment, by generating, adjusting and filtering multiple initial location combinations, and combining the shortest path, hot zone, and cooperative gain threshold triple constraints for filtering, unreasonable and inefficient site combinations can be eliminated, ensuring the quality of the initial population for subsequent optimization and improving the rationality and reliability of the planning results.
[0108] In some embodiments, determining the target location combination based on the first intermediate location combination includes: obtaining a fitness value for the first intermediate location combination based on any candidate construction location in any first intermediate location combination and the number of third charging piles of the planned charging piles at the candidate construction locations; sorting all first intermediate location combinations in descending order of fitness value, and determining the top preset number of first intermediate location combinations in the sorting result as second intermediate location combinations; for any two second intermediate location combinations, determining one of the second intermediate location combinations as the first location combination, and determining the remaining second intermediate location combination as the second location combination; selecting at least one first candidate construction location from the first location combination and at least one second candidate construction location from the second location combination, and combining the at least one first candidate construction location with at least one second candidate construction location. The location combination formed by the second candidate construction locations is determined as the third intermediate location combination; at least one third candidate construction location is selected from the first location combination, and at least one fourth candidate construction location is selected from the second location combination. The number of charging piles to be planned at the third candidate construction location is determined as the new number of charging piles to be planned at the fourth candidate construction location, and the number of charging piles to be planned at the fourth candidate construction location is determined as the new number of charging piles to be planned at the third candidate construction location. The number of third candidate construction locations is the same as the number of fourth candidate construction locations. The first location combination and the second location combination after adjusting the number of charging piles are determined as the fourth intermediate location combination, and the third intermediate location combination and the fourth intermediate location combination are determined as the fifth intermediate location combination. The target location combination is determined based on the fifth intermediate location combination.
[0109] Among them, the fitness value is a quantitative index obtained based on the comprehensive fitness function. It is used to characterize the quality of the location combination of candidate construction sites. The larger the fitness value, the wider the coverage of the corresponding location combination, the more reasonable the resource allocation, and the better the overall planning effect.
[0110] Alternatively, if a genetic algorithm is used to optimize the combination of the second middle positions, a two-point crossover method can be used to process the combination of the second middle positions into a third middle position combination, or an ordered crossover method can be used to process the combination of the second middle positions into a fourth middle position combination.
[0111] In this embodiment, by selecting the best solution based on fitness value and optimizing the combination of best locations by cross-referencing and exchanging the number of charging piles, better planning combinations can be continuously generated through iteration, thereby improving the overall planning effect and ensuring the rationality, efficiency and optimality of the final target location combination.
[0112] In some embodiments, determining the target location combination based on the fifth intermediate location combination includes: making a first adjustment to at least one candidate construction location in any fifth intermediate location combination; obtaining the center point location of the center point of any demand hot zone, and obtaining the distance between the candidate construction location after the first adjustment and the center point location; making a second adjustment to the candidate construction location after the first adjustment based on the center point location with the smallest corresponding distance and the candidate construction location after the first adjustment according to a preset adjustment probability, and determining the fifth intermediate location combination after the second adjustment of the candidate construction location as the sixth intermediate location combination; adjusting the number of charging piles of the planned charging piles at at least one candidate construction location in any sixth intermediate location combination, and determining the sixth intermediate location combination after adjusting the number of charging piles as the seventh intermediate location combination; and determining the target location combination based on the seventh intermediate location combination.
[0113] Optionally, in the process of optimizing the combination of positions using a genetic algorithm, the first adjustment of at least one candidate construction position is equivalent to genetic mutation of the candidate construction position; after the first adjustment, a hot zone gravity mechanism can be introduced to activate the probability (preset adjustment probability). This mechanism determines whether to redirect candidate construction locations, adjusted in the first round, to their nearest hotspot center to enhance coverage in high-demand areas. This helps strengthen the coverage density of individuals within the population in high-demand areas, improving service quality while avoiding ineffective location drift caused by mutations. It can be, but is not limited to, 0.3. Specifically, the distance between the candidate construction location after the first adjustment and the center point of any demand hot zone is calculated. After a preset adjustment probability indicates that the candidate construction location after the first adjustment needs to be adjusted a second time, based on the center point with the smallest corresponding distance to the candidate construction location after the first adjustment, and the candidate construction location after the first adjustment, the new location of the candidate construction location after the second adjustment is determined, and the candidate construction location after the first adjustment is adjusted to this new location. If the new location after the second adjustment is close to the center point with the smallest corresponding distance, the number of charging piles of the planned charging station at the candidate construction location after the first adjustment will also be fine-tuned according to the hot zone weight of the demand hot zone where the center point with the smallest corresponding distance is located. The new location after the second adjustment is shown in the following formula:
[0114]
[0115] In the formula, This is the new position after the second adjustment. These are the candidate construction locations after the first adjustment. In order to align with the first adjusted candidate construction locations The location of the center point of the demand hot zone with the smallest corresponding distance between them. The range of values is The coefficient.
[0116] Optionally, when adjusting the number of charging piles to be planned at candidate construction locations in the sixth intermediate location combination, the adjusted number of charging piles to be planned... The quantity must not exceed the threshold. This ensures a smooth transition in scale and avoids excessive fluctuations.
[0117] Optionally, genetic operations such as selection, crossover, and mutation can be performed iteratively to continuously update the population and optimize site selection and scale configuration.
[0118] In this embodiment, by adjusting the candidate construction locations twice and optimizing the number of charging piles, the sites can be made closer to the center of the demand hotspot, further improving the coverage of charging services and resource utilization, making the final planning scheme more in line with actual charging needs and more practical.
[0119] In some embodiments, determining a target location combination based on a seventh intermediate location combination includes: obtaining sixth charging demand data that can be met by planned charging piles at all candidate construction locations in any seventh intermediate location combination, and seventh charging demand data required within the charging service coverage area of all candidate construction locations, and obtaining a second ratio between the sixth charging demand data and the seventh charging demand data; for any candidate construction location in the seventh intermediate location combination, obtaining eighth charging demand data that can be met by planned charging piles at the candidate construction location, and ninth charging demand data required within the charging service coverage area of the candidate construction location; obtaining a second difference between the eighth charging demand data and the ninth charging demand data, and determining a first demand matching degree for the candidate construction location based on a third ratio between the second difference and the ninth charging demand data; obtaining a second demand matching degree for the corresponding seventh intermediate location combination based on the first demand matching degree; performing a weighted summation of the second ratio and the second demand matching degree, and determining a target location combination for the power supply area from the seventh intermediate location combination based on the weighted summation result.
[0120] Optionally, but not limited to, the absolute value of the third ratio can be determined as the first demand matching degree of the candidate construction location; the corresponding second demand matching degree of the seventh intermediate location combination can be calculated as follows:
[0121]
[0122] Optionally, For the second requirement matching degree, Let N be the first requirement matching degree, and N be the number of candidate construction locations in the seventh middle position combination.
[0123] Optionally, the process of weighted summation of the second ratio and the second demand matching degree is shown in the following formula:
[0124]
[0125] In the formula, and All are weighting parameters, with CD being the second ratio.
[0126] Optionally, the seventh middle position combination with the largest result of the corresponding weighted summation is determined as the target position combination.
[0127] Optionally, it is possible to Optimize the solution across multiple scenarios within the range of demand disturbances to improve its robustness; design a flexible range for scale. This enhances the flexibility of the solution; it accelerates fitness calculation by adopting parallel computing architectures (such as OpenMP); among which, OpenMP is an API for shared memory parallel programming, which can realize code parallelization to improve computational efficiency.
[0128] In this embodiment, by quantifying the overall demand matching (second ratio) and the demand matching of individual candidate locations (first demand matching degree), and combining the weighted summation to comprehensively evaluate the seventh intermediate location combination, it can not only ensure the balance between the overall charging demand of the power supply area and the supply of charging piles, but also take into account the supply and demand adaptability of individual sites, eliminate schemes with supply and demand imbalance, improve the rationality and accuracy of the target location combination, and ensure that the planning scheme fits the actual charging demand.
[0129] In some embodiments, the method further includes: acquiring geographic topology data of the power supply area, and constructing an undirected graph corresponding to the power supply area based on the geographic topology data; wherein, nodes in the undirected graph represent candidate construction locations of charging stations, and edges in the undirected graph represent paths between different candidate construction locations; inputting the undirected graph into a Floyd shortest path model, and outputting the length of the shortest path between any two candidate construction locations.
[0130] The Floyd shortest path model is a dynamic programming algorithm model used to find the shortest path between any two nodes in a graph. It can obtain the shortest path between all pairs of nodes in the graph by iteratively updating the path length between nodes.
[0131] In this embodiment, by constructing an undirected graph and adopting the Floyd shortest path model, the shortest path length between any two candidate construction locations within the power supply area can be calculated accurately and efficiently. This provides an accurate and reliable path basis for subsequent distance judgment between stations, cooperative gain calculation, and location combination optimization, thereby improving the rationality and accuracy of determining the construction location of charging stations.
[0132] In one exemplary embodiment, another method for determining the construction location of a charging station is provided, including the following:
[0133] (1) The locations of potential sites within urban village areas are abstracted as nodes in the graph, and the spatial relationships and distance matrices between nodes are obtained. The Floyd algorithm is used to calculate the shortest path between any two points in the entire graph, realizing global service reachability modeling. It supports a scale of over 500 nodes and is suitable for practical application scenarios in high-density areas.
[0134] (2) Based on historical charging behavior, building distribution, and demand point density, service set and node demand potential indicators are defined. Using the density-based clustering algorithm (DBSCAN), hotspot areas are automatically extracted based on the service influence radius, significantly improving the spatial resolution of demand identification. Hotspot weights are constructed through weighted statistics to provide a quantitative priority basis for subsequent site selection.
[0135] (3) For station pairs in the same hot zone or adjacent areas, analyze the intersection of their service ranges, evaluate the collaborative gain of the remaining unmet needs in the intersection area, and construct a service collaboration network between the node pairs. Use sparse matrices to efficiently store the gain values, improve computational performance, and avoid redundant calculations.
[0136] (4) A chromosome encoding method including "site location + construction scale" is adopted, and novel genetic operators such as heat zone-aware hierarchical initialization strategy, scale-aware dynamic pruning mechanism, pruning operator based on cooperative gain, heat zone gravity mutation mechanism and scale stability crossover operator are introduced for the first time in the charging facility planning problem. This design takes into account both the spatial rationality of the solution and the convergence efficiency, and has good engineering practicality.
[0137] (5) Construct a multi-dimensional fitness function for service coverage and scale-demand matching, and systematically evaluate the service effectiveness and resource utilization efficiency of the solution. The fitness function fully considers the rationality of the total coverage demand and scale configuration to avoid resource waste and demand mismatch.
[0138] (6) Considering the daily fluctuations and behavioral uncertainties of the charging load of new energy vehicles, this invention introduces a multi-scenario simulation mechanism within a ±5% disturbance range and allows the scale configuration value of each site to be adjusted within a preset elastic range to improve the adaptability of the scheme to future changes in operating conditions.
[0139] (7) To address the problem of high computational complexity of fitness function, an OpenMP parallel evaluation structure is constructed to support efficient processing of parallel scoring and evolution of multiple individuals under large-scale node sets, significantly improving the scalability of the algorithm in engineering-level deployment environments.
