Description

Technical Field

[0001] This invention relates to the field of pumped storage power station technology, specifically to layout analysis methods, devices, equipment, media, and products for pumped storage power stations. Background Technology

[0002] With the development of energy storage demand, the construction requirements for pumped storage power stations are becoming increasingly stringent. In order to ensure the number of pumped storage power stations in various regions, it is necessary to conduct statistics and layout analysis on both completed and uncompleted pumped storage power stations.

[0003] The statistical methods for pumped storage power stations in related technologies usually require technicians to manually count the number of pumped storage power stations in each region. This method is inefficient, prone to errors, and has low accuracy in classifying and counting pumped storage power stations that have been built and those that have not yet been built. It is difficult to meet the analytical needs of large-scale pumped storage power station layout planning. Summary of the Invention

[0004] This invention provides a layout analysis method, apparatus, equipment, medium, and product for pumped storage power stations, to solve the problem that statistical methods for pumped storage power stations in related technologies are difficult to meet the analysis needs of large-scale pumped storage power station layout planning.

[0005] In a first aspect, the present invention provides a layout analysis method for pumped storage power stations, comprising: acquiring location layer point vector files of multiple pumped storage power stations, acquiring region boundary surface vector files of multiple regions, spatially connecting the location layer point vector files and the region boundary surface vector files to obtain a target connection layer; constructing multiple progress vector layers on the target connection layer according to the project progress in the location layer point vector files; determining the total installed capacity of each progress vector layer corresponding to each region according to the location layer point vector files; classifying layout levels for each region according to the total installed capacity of each progress vector layer corresponding to each region and the region's installed capacity requirements, and rendering the layout on the target connection layer according to the layout levels for each region.

[0006] The layout analysis method for pumped storage power stations of this invention spatially connects the location layer point vector file of the pumped storage power stations with the regional boundary surface vector files of multiple regions to obtain a target connection layer. This automatically establishes the spatial affiliation relationship between each pumped storage power station and its corresponding region, eliminating the need for manual verification of each power station's location and significantly improving the efficiency and accuracy of region affiliation determination. Based on the construction progress in the location layer point vector file, this invention constructs multiple progress vector layers on the target connection layer, enabling hierarchical management and independent presentation of pumped storage power station data at different construction stages, making the distribution of pumped storage power stations at each progress stage clearer. Based on the location layer point vector file, this invention determines the total installed capacity of each progress vector layer corresponding to each region. By automatically calculating the total installed capacity of each region under each progress vector layer, it can accurately quantify the pumped storage installed capacity level at different construction stages in each region. This invention classifies each region into layout levels based on the total installed capacity of each progress vector layer corresponding to each region and the region's installed capacity requirements. The layout levels are then rendered on the target connection layer according to these levels. By matching and comparing the total installed capacity of each region at each progress stage with the region's installed capacity requirements and classifying the layout levels, the installed capacity of each region can be intuitively identified. This provides decision-making guidance for the subsequent planning of pumped storage power stations in each region. Rendering and displaying the layout analysis results on the target connection layer according to the layout levels achieves map visualization, making the advantages and disadvantages of regional layouts clearer and significantly improving the intuitiveness and efficiency of planning decisions.

[0007] In one optional implementation, the method involves acquiring location layer point vector files for multiple pumped storage power stations, acquiring regional boundary surface vector files for multiple regions, and spatially connecting the location layer point vector files and regional boundary surface vector files to obtain a target connection layer. This includes: acquiring basic information about multiple pumped storage power stations, converting the location coordinates in the basic information into spatial point features, associating the attribute data in the basic information with the spatial point features to obtain location layer point vector files; acquiring initial surface vector files for multiple regions, associating the regional installed capacity demand information and region name information with the initial surface vector files to obtain regional boundary surface vector files; and matching the location coordinates in the location layer point vector files with the spatial positions in the regional boundary surface vector files to obtain the target connection layer.

[0008] In one optional implementation, multiple progress vector layers are constructed on the target connection layer based on the project progress in the location layer point vector file, including: constructing a vector layer for the pumped storage power station corresponding to each progress label based on the project progress in the location layer point vector file, thereby obtaining multiple progress vector layers.

[0009] In one optional implementation, the total installed capacity of each progress vector layer corresponding to each region is determined based on the location layer point vector file, including: extracting the installed capacity field of each progress vector layer corresponding to each region from the location layer point vector file; and statistically analyzing the value of the installed capacity field of each progress vector layer to obtain the total installed capacity of each progress vector layer.

[0010] In one optional implementation, based on the total installed capacity of each progress vector layer corresponding to each region and the region's installed capacity requirement, a layout level is defined for each region, and rendering is performed on the target connection layer according to the layout level defined for each region. This includes: obtaining the first total installed capacity of the first progress and the second total installed capacity of the second progress corresponding to each region based on the total installed capacity of each progress vector layer corresponding to each region; the first progress is the completed progress, and the second progress is the under-construction progress; if the first total installed capacity of a region is greater than the region's installed capacity requirement, the region is classified as a first layout level region; if the sum of the first and second total installed capacity of a region is greater than or equal to the region's installed capacity requirement, the region is classified as a second layout level region; if the sum of the first and second total installed capacity of a region is less than the region's installed capacity requirement, the region is classified as a third layout level region; and rendering the first, second, and third layout level regions on the target connection layer according to preset rendering rules.

[0011] In an optional implementation, the layout analysis method for pumped storage power stations further includes: acquiring substation vector files of multiple substations and new energy base surface element vector files of new energy bases; writing the identifier name of the target substation into the substation field of the layer point vector file based on the location layer point vector file and the substation vector file; the target substation is a substation whose distance from the pumped storage power station is less than a first preset distance; writing the identifier name of the target new energy base into the new energy base field of the layer point vector file based on the location layer point vector file and the new energy base surface element vector file; the target new energy base is a new energy base whose distance from the pumped storage power station is less than a second preset distance.

[0012] The layout analysis method for pumped storage power stations of this invention acquires vector files of substation sites from multiple substations and vector files of renewable energy base surface elements, improving the data dimensions of pumped storage power station layout analysis. This expands the analysis beyond the relationship between the pumped storage power station itself and its surrounding area, taking into account the distribution of surrounding power infrastructure and renewable energy resources. By automatically matching target substations around the pumped storage power station based on a first preset distance and directly writing their identifiers into the attribute fields of the layer point vector files, the spatial relationship between each pumped storage power station and its neighboring substations can be quickly established without manual investigation and labeling, improving the efficiency and accuracy of identifying the supporting relationships between pumped storage power stations and substations. Furthermore, by automatically matching target renewable energy bases around the pumped storage power station based on a second preset distance and writing their identifiers into the attribute fields, this invention can automatically identify renewable energy bases geographically adjacent to the pumped storage power station, intuitively reflecting the potential for coordinated development between the power station and the renewable energy base. This provides a quantitative spatial correlation basis for optimizing the collaborative layout of renewable energy bases and pumped storage power stations and improving the level of renewable energy absorption.

[0013] Secondly, the present invention provides a layout analysis device for pumped storage power stations, comprising: a file acquisition module, used to acquire multiple location layer point vector files of pumped storage power stations, acquire multiple region boundary surface vector files of regions, and spatially connect the location layer point vector files and the region boundary surface vector files to obtain a target connection layer; a layer construction module, used to construct multiple progress vector layers on the target connection layer according to the project progress in the location layer point vector files; an installed capacity determination module, used to determine the total installed capacity of each progress vector layer corresponding to each region according to the location layer point vector files; and a layer rendering module, used to divide each region into layout levels according to the total installed capacity of each progress vector layer corresponding to each region and the region's installed capacity requirements, and render the layout on the target connection layer according to the layout levels divided for each region.

[0014] Thirdly, the present invention provides an electronic device, comprising: a memory and a processor, wherein the memory and the processor are communicatively connected to each other, the memory stores computer instructions, and the processor executes the computer instructions to perform the layout analysis method for pumped storage power stations described in the first aspect or any corresponding embodiment thereof.

[0024] This invention provides a layout analysis method for pumped storage power stations. By associating pumped storage power stations with regions, the total installed capacity of each region is analyzed to achieve the effect of layout analysis of pumped storage power stations.

[0025] According to an embodiment of the present invention, a layout analysis method for a pumped storage power station is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0026] This embodiment provides a layout analysis method for pumped storage power stations, which can be used with computer equipment. Figure 2 This is a first flowchart of a layout analysis method for a pumped storage power station according to an embodiment of the present invention, as shown below. Figure 2 As shown, the process includes the following steps: Step S201: Obtain the location layer point vector files of multiple pumped storage power stations, obtain the region boundary surface vector files of multiple regions, and spatially connect the location layer point vector files and the region boundary surface vector files to obtain the target connection layer.

[0027] Among them, pumped storage power stations are energy storage hydropower stations that use electricity during off-peak hours to pump water to the upper reservoir and release water to the lower reservoir to generate electricity during peak hours.

[0028] In some optional implementations, the location layer point vector file is a vector data layer file that stores the geographical coordinates of the pumped storage power station in the geometric form of point features, and includes various basic information about the pumped storage power station. For example, the various basic information includes the name of the power station, its longitude and latitude, installed capacity (ten thousand kilowatts), project progress (built, under construction, approved, feasibility study reviewed, three major thematic studies reviewed, pre-feasibility study reviewed), etc.

[0029] In some alternative implementations, a region is an administrative or planning unit with clearly defined geographical boundaries, such as an administrative region or a specific planning zone.

[0030] In some alternative implementations, the region boundary surface vector file is a vector data layer file that stores the region boundary extent in the form of surface feature geometry and includes various region information, such as region identifier name, pumped storage demand (in kilowatts), etc.

[0031] In some optional implementations, the target connection layer is the result layer output after spatial connection operations on the location layer point vector file and the region boundary polygon vector file, and contains the attributes of the original point features and the attributes of the polygon features into which they fall.

[0032] In some alternative implementations, spatial connectivity operations are performed to establish spatial attribute associations between points and surfaces, resulting in a target connectivity layer.

[0033] Step S202: Based on the project progress in the location layer point vector file, construct multiple progress vector layers on the target connection layer.

[0034] Among them, the project progress refers to the construction stage attributes of pumped storage power stations, including different progress statuses such as planning, under construction, already in operation, and approved.

[0035] In some alternative implementations, the progress vector layer is an independent vector layer generated after being divided according to the project progress category, and each layer contains only the power plant elements of a specific progress stage.

[0036] In some optional implementations, the progress vector layer corresponding to each progress step is generated from the target connection layer by using the progress of the project in the location layer point vector file as a filtering criterion.

[0037] Step S203: Based on the location layer point vector file, determine the total installation scale of each progress vector layer corresponding to each region.

[0038] The total installed capacity is the sum of the installed capacity of all pumped storage power stations in each progress vector map layer corresponding to each region.

[0039] In some optional implementations, the total installed capacity of each progress vector layer corresponding to each region is summed based on the location layer point vector file to obtain the total installed capacity of each progress vector layer corresponding to each region.

[0040] Step S204: Based on the total installation scale of each progress vector layer corresponding to each region and the installation scale requirement of each region, divide the layout level for each region, and render the target connection layer according to the layout level of each region.

[0041] Among them, the regional installed capacity demand is the target value of pumped storage installed capacity demand calculated by each region based on factors such as power load and new energy consumption.

[0042] In some alternative implementations, the layout level is a graded evaluation result of each region based on the degree of matching between the total installed capacity and demand.

[0043] In some alternative implementations, rendering is an operation that symbolizes and colors layer features, presenting the data in an intuitive visual way.

[0044] In some optional implementations, the comparison between the total installed capacity and demand is used as the basis for classification. Each region is classified into different level categories according to preset standards or thresholds, and symbolic configuration and color display operations are performed on the layer elements of the target connected layer.

[0045] The layout analysis method for pumped storage power stations provided in this embodiment spatially connects the location layer point vector files of pumped storage power stations with the regional boundary surface vector files of multiple regions to obtain a target connection layer. This automatically establishes the spatial affiliation relationship between each pumped storage power station and its corresponding region, eliminating the need for manual verification of each power station's location and significantly improving the efficiency and accuracy of region affiliation determination. Based on the construction progress in the location layer point vector files, this embodiment constructs multiple progress vector layers on the target connection layer. This allows for hierarchical management and independent presentation of pumped storage power station data at different construction stages, making the distribution of pumped storage power stations at each progress stage clearer. Furthermore, based on the location layer point vector files, this embodiment determines the total installed capacity of each progress vector layer corresponding to each region. By automatically calculating the total installed capacity of each region under each progress vector layer, it accurately quantifies the pumped storage installed capacity level at different construction stages in each region. This invention, in its embodiments, classifies each region into layout levels based on the total installed capacity of each progress vector layer corresponding to each region and the region's installed capacity requirements. The layout levels are then rendered on the target connection layer according to these regional classifications. By matching and comparing the total installed capacity of each region at each progress stage with the region's installed capacity requirements and classifying the layout levels, the installed capacity of each region can be intuitively identified. This provides decision-making guidance for the subsequent planning of pumped storage power stations in each region. Rendering and displaying the layout analysis results on the target connection layer according to layout levels achieves map visualization, making the regional layout advantages and disadvantages clearer and significantly improving the intuitiveness and efficiency of planning decisions.

[0046] This embodiment provides a layout analysis method for pumped storage power stations, which can be used with computer equipment. Figure 3 This is a second flowchart of the layout analysis method for pumped storage power stations according to an embodiment of the present invention, as shown below. Figure 3 As shown, the process includes the following steps: Step S301: Obtain the location layer point vector files of multiple pumped storage power stations, obtain the region boundary surface vector files of multiple regions, and spatially connect the location layer point vector files and the region boundary surface vector files to obtain the target connection layer.

[0047] Specifically, step S301 includes: Step S3011: Obtain basic information of multiple pumped storage power stations, convert the location coordinates in the basic information into spatial point features, associate the attribute data in the basic information with the spatial point features, and obtain the location layer point vector file.

[0048] This involves acquiring basic information about multiple pumped storage power stations to obtain a basic information table, which lists the basic information of each pumped storage power station.

[0049] In some optional implementations, ArcGIS (a tool for capturing, storing, processing, analyzing, and visualizing geographic data) is used to convert the location coordinates in the basic information into spatial point features. The attribute data in the basic information is then associated with the spatial point features to obtain a location layer point vector file. Specifically, the basic information table is imported into ArcGIS, and the basic information table containing location coordinates is converted into a point feature vector file on the map. Specifically, the latitude and longitude values ​​of each pumped storage power station in the basic information table are read line by line. Based on the built-in geographic coordinate algorithm, the latitude and longitude values ​​are converted into geographic coordinate point geometric objects, and spatial point features are automatically generated and stored on the local hard drive. At the same time, the attribute data in the basic information is associated with the spatial point features and bound to the attribute library to obtain the location layer point vector file point.shp.

[0050] For example, attribute data includes text attributes such as the identifier name of the pumped storage power station, installed capacity, and project progress.

[0051] Step S3012: Obtain initial surface vector files for multiple regions, associate the region's installed capacity requirement information and region name information with the initial surface vector files to obtain the region boundary surface vector files.

[0052] This involves obtaining initial polygon vector files for multiple regions through a regional geographic information system.

[0053] In some alternative implementations, ArcGIS is used to associate the regional installation scale requirement information and regional name information with the initial polygon vector file to obtain the regional boundary polygon vector file.

[0054] Among them, the regional installed capacity demand information is the pre-set installed capacity information that needs to be met in the region, and the regional name information is the regional identifier name, which makes it easy to distinguish and identify different regions.

[0055] In some optional implementations, the regional installation scale requirement information and regional name information are attribute-bound to the corresponding polygon features in the initial polygon vector file and stored in the layer attribute library to obtain the regional boundary polygon vector file province.shp.

[0056] Step S3013: Match the position coordinates in the position layer point vector file with the spatial position in the region boundary surface vector file to obtain the target connection layer.

[0057] Specifically, coordinate projection transformation is performed on the location layer point vector file and the regional boundary surface vector file. The geographic coordinate system is converted into the corresponding strip projection coordinate system according to the location of the pumped storage power station. Cross-zone data is converted in batches according to the strip to which it belongs. The files to be matched subsequently are the location layer point vector file and the regional boundary surface vector file after coordinate transformation.

[0058] Specifically, the process iterates through all layers of the location layer point vector file and the region boundary surface vector file, identifies the current coordinate system identifier, automatically writes geographic coordinate system reference parameters for layers without projection files, updates the layer projection file, loads the target region Gauss-Kruger zone projection parameters for layers with only geographic coordinates (latitude and longitude), iterates through all point and surface geometric vertices for each feature, performs mathematical operations for the seven-parameter coordinate transformation, batch converts latitude and longitude geographic coordinates to planar projection coordinates, overwrites or saves the newly vectorized layer after projection correction to the hard drive, unifies the spatial reference of all layers, and eliminates subsequent spatial matching misalignment and empty matching calculation errors.

[0059] In some optional implementations, ArcGIS is used to spatially connect the location layer point vector file and the regional boundary polygon vector file. The two layers are matched based on their spatial location relationship; that is, without a unified code, matching is based on geographic location to match the pumped storage power station to its corresponding region. Specifically, the location coordinates in the location layer point vector file are used as the target features, the spatial location in the regional boundary polygon vector file is used as the connecting features, the point being within the polygon is used as the spatial matching rule, and the regional identifier name is used as the unique identifier. A spatial index retrieval algorithm is activated to construct a spatial index for the polygons of multiple regions. The geometry of each pumped storage point is traversed to quickly retrieve the polygon features of the region that completely contain that point. The attribute information of the successfully matched regional polygons is automatically extracted and appended to the location layer point vector file, generating a new spatial connection result vector layer, thus obtaining the target connection layer. Each pumped storage power station feature is bound to its corresponding regional identifier name.

[0060] Step S302: Based on the project progress in the location layer point vector file, construct multiple progress vector layers on the target connection layer.

[0061] Specifically, step S302 includes: Step S3021: Based on the project progress in the location layer point vector file, construct a vector map layer for each progress label corresponding to the pumped storage power station to obtain multiple progress vector map layers.

[0062] In this process, the pumped storage power station corresponding to each project progress label is selected from the location layer point vector file to form a new layer, resulting in multiple progress vector map layers. For example, the progress labels "under construction, approved, feasibility study reviewed, and pre-feasibility study reviewed" are selected respectively to generate multiple sets of progress vector map layers in batches.

[0063] Specifically, based on the progress label corresponding to the project progress, the full attribute table of the location layer point vector file is traversed, and the text value of the "project progress" field is compared line by line. All point feature geometry and attributes that meet the conditions are filtered out, and the filtered results are generated into a new vector layer. The filtering procedure is repeated to match the conditions such as "under construction, approved, and feasibility study reviewed" to obtain multiple progress vector layers.

[0064] Step S303: Based on the location layer point vector file, determine the total installation scale of each progress vector layer corresponding to each region.

[0065] Specifically, step S303 includes: Step S3031: Extract the installation scale field of each progress vector layer corresponding to each region from the location layer point vector file.

[0066] Step S3032: Statistically analyze the values ​​of the installation scale field for each progress vector map layer to obtain the total installation scale for each progress vector map layer.

[0067] Specifically, ArcGIS is used to calculate the total installed capacity of each region at different stages of construction, such as completed, under construction, and approved. This yields the total installed capacity of each progress vector layer. The field to be counted is the installed capacity, and the grouping field is the region identifier name. The statistical result is an attribute table containing the corresponding region identifier name, project progress, frequency of statistics, and total installed capacity.

[0068] Specifically, the input layer is a phased pumped storage layer, the statistical field is the installed capacity, and the grouping field is the region identifier name; all data in the layer attribute table is read, a hash index is built based on the grouping field, and all pumped storage installed capacity values ​​in the same region are grouped into the same group; numerical accumulation is performed, and the total installed capacity and project frequency of each group are automatically calculated, generating a new statistical data table and storing it on the hard drive; the output table has the following built-in fields: region identifier name, project progress, number of projects, and total installed capacity.

[0069] In some optional implementations, the total installed capacity of each progress vector layer is associated with the region boundary vector file, using the region identifier name as the association key field. The region surface features are automatically matched with the corresponding total installed capacity. Custom fields are added to the attribute table in the region boundary vector file, and the statistically obtained installed capacity values ​​are written in batches to the custom fields of the corresponding regions.

[0070] Step S304: Based on the total installation scale of each progress vector layer corresponding to each region and the installation scale requirement of each region, divide the layout level for each region, and render the target connection layer according to the layout level of each region.

[0071] Specifically, step S304 includes: Step S3041: Based on the total installed capacity of each progress vector layer corresponding to each region, obtain the first total installed capacity of the first progress and the second total installed capacity of the second progress for each region; the first progress is the completed progress, and the second progress is the progress under construction.

[0072] In the attribute table of the regional boundary surface vector file, the total installed capacity corresponding to each progress of each region is filtered.

[0073] Step S3042: When the total installed capacity of the first region exceeds the region's installed capacity requirement, the region is classified as a first-level layout region.

[0074] Among them, the first layout level area can be the area with the most complete layout planning. When the total installed capacity of the first level, that is, the total installed capacity of the completed projects, is greater than the regional installed capacity demand, it means that the scale of the existing power stations has met the space demand of pumped storage power stations in the province, and there is no need to conduct layout analysis of pumped storage power stations for the time being.

[0075] In some optional implementations, the level field corresponding to the first layout level area is assigned a value of 1.

[0076] Step S3043: When the sum of the first total installed capacity and the second total installed capacity of the region is greater than or equal to the region's installed capacity demand, the region is divided into a second layout level region.

[0077] Among them, the second layout level area can be the area with the least complete layout plan. When the sum of the first and second installed capacity of the area, that is, the sum of the total installed capacity that has been completed and the total installed capacity that is under construction, is greater than or equal to the area's installed capacity demand, it means that the total approved installed capacity that has been built and is under construction can meet the demand, and the construction of pumped storage power stations under construction can be temporarily promoted.

[0078] In some optional implementations, the level field corresponding to the second layout level area is assigned a value of 2.

[0079] Step S3044: If the sum of the first and second total installed capacity of the region is less than the region's installed capacity requirement, then the region is divided into a third-level layout region.

[0080] Among them, the third layout level area can be the area with the least perfect layout planning. When the sum of the first and second installed capacity of the area, that is, the sum of the total installed capacity that has been completed and the total installed capacity that is under construction, is less than the area's installed capacity demand, it means that the total approved installed capacity that has been built and is under construction cannot meet the demand, and there is still a capacity gap in the area.

[0081] In some optional implementations, the level field corresponding to the third layout level area is assigned a value of 3.

[0082] In some optional implementations, the loading judgment logic condition is: the required installed capacity in this area is less than or equal to the existing pumped storage installed capacity in this area; each regional-level feature attribute is traversed, and the values ​​of the two numerical fields, "requirement" and "existing", are compared row by row to filter regional features that meet the condition; a new integer field "meets spatial level" is created, and the selected features are automatically assigned numerical values; the field of features that do not meet the condition is assigned a default value of 0; all numerical comparisons, field creation, and batch assignment are completed automatically by the computer, without the need for manual editing of the attribute table row by row.

[0083] Step S3045: Render the first layout level area, the second layout level area, and the third layout level area on the target connection layer according to the preset rendering rules.

[0084] The process includes: reading the complete attribute dataset of the regional-level polygon layer from the updated regional boundary polygon vector file; receiving hierarchical rendering rules input by operators (setting color band hierarchies, legends, and annotation styles according to the "satisfying space" field and the cumulative installed capacity field); executing spatial rendering algorithms to match the corresponding fill color and boundary style for each regional-level polygon feature according to the attribute values; automatically overlaying pumped storage point layers and power facility layers as base maps; automatically generating standardized thematic maps, supporting export to PDF and image formats to the hard drive, and automatically outputting visualization results.

[0085] In some optional implementations, the layout analysis method for pumped storage power stations further includes: acquiring substation vector files of multiple substations and new energy base surface element vector files of new energy bases; writing the identifier name of the target substation into the substation field of the layer point vector file based on the location layer point vector file and the substation vector file; the target substation is a substation whose distance from the pumped storage power station is less than a first preset distance; writing the identifier name of the target new energy base into the new energy base field of the layer point vector file based on the location layer point vector file and the new energy base surface element vector file; the target new energy base is a new energy base whose distance from the pumped storage power station is less than a second preset distance.

[0086] This involves exporting vector files for multiple substations in each region, specifically substation.shp, and vector files for new energy base features, specifically large base.shp. The substation vector files include attribute information such as the substation's name and voltage, while the new energy base vector files include attribute information such as the base's installed capacity and base name.

[0087] In some alternative implementations, a substation may include a converter station, an AC substation, and a switchyard.

[0088] In some optional implementations, a location layer point vector file is used as the source layer, and a substation vector file is used as the target layer. The substation field of the location layer point vector file contains the identifier name of the target substation and the distance between the target substation and the pumped storage power station. The first preset distance is kept as small as possible to ensure that the target substation is the closest substation to the pumped storage power station. Layout analysis is performed based on the distance between the target substation and the pumped storage power station; generally, substations that are closer have lower transmission costs and faster response times for participating in network-wide voltage regulation.

[0089] Specifically, a spatial index of power facility points is constructed, each pumped storage power station location is traversed, and all substations within the spatial range are searched. The straight-line distance is calculated point by point using the Euclidean distance formula. All distance results are compared, and the substation element corresponding to the minimum value is selected. The unique representation of this element and the minimum straight-line distance are extracted and written into the substation field, and the point.shp attribute table is updated synchronously. The built-in formula for calculating the investment of power transmission projects is retrieved, the minimum straight-line distance of the substation field is read, and the static investment of power transmission projects for each pumped storage power station is calculated in batches. The newly added investment field is stored in the attribute table.

[0090] In some optional implementations, the location layer point vector file is used as the source layer, and the new energy base surface feature vector file is used as the target layer. The target new energy base's identifier name and its distance from the pumped storage power station are entered into the new energy base field of the location layer point vector file. The second preset distance is kept as small as possible to ensure that the target new energy base is the closest new energy base to the pumped storage power station. Layout analysis is then performed based on the distance between the target new energy base and the pumped storage power station.

[0091] Specifically, a spatial index of power facility points is constructed, traversing each pumped storage power station location and searching all new energy bases within the spatial range. The straight-line distance is calculated point-by-point using the Euclidean distance formula. All distance results are compared, and the new energy base element corresponding to the minimum value is selected. The unique representation of this element and its minimum straight-line distance are extracted and written into the new energy base field, and the point.shp attribute table is updated synchronously. The built-in formula for calculating the investment of power transmission projects is retrieved, and the minimum straight-line distance in the new energy base field is read to automatically classify peak-shaving adaptability levels. Near-distance pumped storage is marked as high-adaptability peak-shaving resource, and far-distance is marked as low-adaptability. The level field is assigned values ​​in batches by the computer.

[0092] The layout analysis method for pumped storage power stations provided in this embodiment acquires vector files of substation sites from multiple substations and vector files of new energy base surface elements from new energy bases. This improves the data dimension of pumped storage power station layout analysis, allowing the analysis to go beyond the relationship between the pumped storage power station itself and the region, while also considering the distribution of surrounding power infrastructure and new energy resources. By automatically matching target substations around the pumped storage power station based on a first preset distance and directly writing their identifiers into the attribute fields of the layer point vector files, the spatial relationship between each pumped storage power station and its neighboring substations can be quickly established without manual investigation and labeling, improving the efficiency and accuracy of sorting out the supporting relationships between pumped storage power stations and substations. This embodiment of the invention also automatically matches target new energy bases around the pumped storage power station based on a second preset distance and writes their identifiers into the attribute fields. This automatically identifies new energy bases geographically adjacent to the pumped storage power station, intuitively reflecting the supporting linkage potential between the power station and the new energy base, and providing a quantitative spatial correlation basis for optimizing the coordinated layout of new energy bases and pumped storage power stations and improving the level of new energy consumption.
