[0043] It should be understood by those skilled in the art that the embodiments described below are only some embodiments of the present invention, rather than all embodiments of the present invention, and these embodiments are intended to explain the technical principles of the present invention, rather than to limit the protection scope of the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should still fall within the protection scope of the present invention.

[0045] It should be noted that the logic and / or steps represented in the flowchart or described in other ways herein, for example, can be considered as a sequenced list of executable instructions for implementing logical functions, and can be specifically implemented in any computer-readable medium for use by an instruction execution system, device or equipment (such as a computer-based system, a system including a processor, or other system that can fetch instructions from an instruction execution system, device or equipment and execute instructions), or used in combination with these instruction execution systems, devices or equipment.

[0046] The flow chart provided by the present embodiment is not intended to indicate that the operation of the method will be performed in any particular order, or that all operations of the method are included in all every case. In addition, the method may include additional operations. Within the scope of the technical thinking provided by the present embodiment method, additional changes may be made to the above method.

[0047] like Figure 1 As shown, in one embodiment, the design method of a photovoltaic power station generally includes:

[0048] Step S101, obtain a 3D model of the photovoltaic power station installation area. Specifically, obtain a 3D model of the area where the photovoltaic power station needs to be built, for example, if it is built on a roof, obtain a 3D model of the house that at least shows the roof.

[0049] Reference Figure 2 As shown, in one embodiment, this step includes:

[0050] Step S201, controlling the drone to take aerial photos of the installation area to obtain a survey image.

[0051] Reference Figure 3 As shown, in one implementation, step S201 includes:

[0052] Step S301, obtaining the address information of the photovoltaic power station installation area. Specifically, the address information may include the geographical coordinates (latitude and longitude) of the installation area, or the administrative area address (administrative division, road house number), etc. That is, the location of the installation area can be determined on the map according to the address information.

[0053] It should be noted that the way to obtain the address information may be to receive the address information input by the user, or may be to receive a point selection signal from the user on a preset plane map, and the location selected by the user is used as the address information.

[0054] Step S302, generating an aerial photography area covering the installation area on the plane map according to the address information. Specifically, the aerial photography area covering the installation area is displayed on the plane map. For example, if the photovoltaic power station needs to be built on the roof of a building, the aerial photography area is a graphic covering the building on the plane map.

[0055] It should be noted that the aerial photography area may be generated by receiving the frame selection information of the user, or may be automatically generated according to the range of the installation area on the plane map.

[0056] Step S303, generating a first aerial photography plan according to the aerial photography area. Specifically, the aerial photography plan includes flight parameters and shooting parameters of the drone, such as flight route, flight speed, shooting interval, shooting angle, and other parameters. The flight route of the first aerial photography plan has route portions located inside and outside the aerial photography area, and at each shooting point located outside the installation area, at least three images of the upper, middle, and lower angles are shot in the direction in which the lens faces the installation area.

[0057] Specifically, the flight route is generally a reciprocating and tortuous route generated according to the aerial photography area. Because it is generated according to the aerial photography area, the first aerial photography plan is to shoot above the installation area. If it is a building roof, the aerial photography is performed above the building roof. In addition, during the drone aerial photography process, at each shooting point outside the installation area, that is, in terms of plane, the drone shooting point is outside the plane graphic range of the installation area, at least three photos are taken in the direction of the lens facing the installation area, one camera is tilted upward to shoot, one camera is shot horizontally, and one camera is tilted downward to shoot.

[0058] Step S304, control the drone to perform aerial photography according to the first aerial photography scheme to obtain a first aerial image. After the first aerial photography scheme is generated, the drone can be controlled to perform photography according to the first aerial photography scheme to obtain a plurality of first aerial images.

[0059] Step S305, generating a second aerial photography plan based on the first aerial image, wherein the flight route of the second aerial photography plan surrounds the installation area, and the flight altitude is lower than the flight altitude of the first aerial photography plan, and at each shooting point, at least three angles of images are shot in the direction of the lens toward the installation area, and three angles of images are shot in the direction of the lens away from the installation area.

[0060] Specifically, after the drone takes pictures according to the first aerial photography plan, a first aerial image is obtained, and the general situation of the installation area and the surrounding environment observed from the top can be obtained based on the first aerial image, so that the second aerial photography plan is generated based on the above information. Because the second aerial photography plan surrounds the installation area, after understanding the general situation of the installation area and the surrounding environment based on the first aerial image, it can be known whether there are obstacles around the installation area that hinder flight, so as to determine the route of the second aerial photography plan.

[0061] The second aerial photography route surrounds the installation area and is lower than the flight altitude of the first aerial photography solution. If the installation area is the roof of a building, the flight route of the second aerial photography solution flies around the building and is lower than the shooting altitude of the first aerial photography solution. In addition, at each shooting point, at least three angles of images are taken in the direction of the lens facing the installation area, and three angles of images are taken in the direction of the lens facing away from the installation area. In this way, it can be more clearly determined whether there are objects around the installation area that are higher than the building, so as to better perform subsequent shadow analysis.

[0062] Step S306: Control the drone to perform aerial photography according to the second aerial photography scheme to obtain a second aerial image. The first aerial image and the second aerial image are used as survey images.

[0063] Reference Figure 4 As shown, in another implementation, step S201 includes:

[0064] Step S401, obtain basic information of the installation area. Basic information may include: location information, terrain information, and grid access equipment information. The location information includes the geographic coordinates (latitude and longitude) of the installation area, the administrative area address (administrative divisions, road numbers), and the distance to surrounding markers. The terrain information includes the altitude, slope and slope direction (the degree of inclination and inclination direction of the ground), the type of foundation layout (roof, wall, ground, other supports), landform type, and infrastructure information (foundation surface flatness, foundation surface covering type) of the installation area. The grid access equipment information includes the access transformer capacity, inverter type, PCS specifications, etc.

[0065] The step of obtaining the location information and terrain information may include: reading the location information and terrain information from the location of the installation area selected in the preset map. The map may be a digital map, which is obtained by digitally processing geographic information using computer technology, and in addition to graphics, may also include terrain data, vector data, description information and other related data. In actual application, the method of this embodiment may determine the location of the installation area on the digital map through the selection operation of the surveyor on the map or according to the input selection information, and read the corresponding location information and terrain information. The location information and terrain information are used as positioning information for the survey on the one hand, and can also be used as basic data for the survey on the other hand.

[0066] The step of obtaining the information of the grid-connected equipment includes: sending a query request to the grid management device according to the location information, and obtaining the grid-connected equipment information of the grid management device in response to the query request. The grid management device can find the corresponding grid-connected equipment information according to the grid deployment data of the installation area. The grid-connected equipment information can be used to limit the technical indicators and economic indicators of the photovoltaic system, such as providing the capacity limit parameters of the photovoltaic system, the consumables cost of the photovoltaic equipment to access the grid (cable specifications and quantity, transformer and PCS expansion costs, etc.), and the grid's restriction conditions for absorbing microgrid power transmission (whether to operate reverse transmission to the grid, and the grid electricity price).

[0067] Step S402, control the drone to perform initial survey and photography of the installation area to obtain an initial image. The initial survey and photography can be performed using the drone's default cruise mode, for example, the drone photographs the installation area at a certain height in a preset scanning photography mode (such as reciprocating along a straight line). The initial image obtained is used to obtain a general understanding of the installation area.

[0068] Step S403, set marker points for the initial image, and divide the initial image into objects based on the marker points to at least determine the installation object and estimate the regional area and terrain characteristics of the installation object. The marker points can be obtained by analyzing the initial image, for example, by finding obvious marker points using pixel threshold segmentation, edge detection, regional growth clustering, machine learning model classification, etc. The marker points may include points such as demarcation points, edge points, feature intensity change points, cluster centers or representative points. In addition to the installation objects (installation roofs, installation walls, vacant ground, etc.), the objects obtained by object division may also include the basic objects of the installation objects (installed building objects, walls, supports, etc.). The estimated regional area and terrain characteristics of the installation object are used for the formulation of the aerial photography plan, not the final survey results.

[0069] Step S404, design an aerial photography plan according to the area and terrain characteristics of the installation object. The aerial photography plan includes the flight parameters and shooting parameters of the drone. The flight parameters may include calculating the navigation altitude, speed, route length, flight time and other data. To ensure the accuracy of the measurement, the same target position can be photographed from at least three directions. The aerial photography plan requires that the captured images have a certain degree of overlap to facilitate subsequent stitching. The aerial photography plan can shoot in multiple directions and at multiple heights for the installation object.

[0070] Step S405, control the drone to perform a first survey and shooting around the installation object according to the aerial photography plan to obtain a survey image of the installation object. The survey image of the installation object may include images taken from multiple directions and multiple heights from multiple shooting points. The shooting points can be arranged in an open, unobstructed location with a large shooting range. After the first survey and shooting is completed, the shooting quality of the survey image (such as clarity, overlap, occlusion status, etc.) can be checked. If an image that does not meet the requirements appears, repeat the shooting.

[0071] Step S406, control the drone to perform a second survey and photography of the surrounding environment objects to obtain a survey image of the surrounding environment objects. The second survey and photography photographs the periphery of the installation object to obtain an image reflecting the overall state of the installation area.

[0072] Step S407, stitching the survey image of the installation object and the survey image of the surrounding environment object to obtain a survey image of the installation area. An optional survey image stitching method includes: performing angle matching on the survey image of the installation object and the survey image of the surrounding environment object to find multiple pairs of matching images; performing grayscale histogram equalization processing and geometric distortion elimination on the multiple pairs of matching images to obtain multiple groups of images to be stitched; extracting feature information from the multiple groups of images to be stitched, stitching and fusing the images according to the feature information, and obtaining survey images of the installation area from multiple angles.

[0073] Angle matching can be done by searching for images with similar shooting directions and shooting ranges through the flight records of drones. The matching images found have similar angles, which can reduce the image calculations (including image translation, scaling, and twisting) in the stitching process and improve processing efficiency. Grayscale histogram equalization and geometric distortion elimination can eliminate the problems caused by geometric distortion and color brightness differences in image processing.

[0074] Feature information is extracted from multiple groups of images to be spliced, and an image transformation model can be established based on the matched features, and finally transformation mapping is performed. The transformation mapping of the method of this embodiment first uses point, line and angle features to estimate the homography matrix of the global transformation, and pre-aligns the spliced ​​images; then the image is gridded, and the grid deformation is constrained by the energy function to achieve grid refinement alignment. Since the shooting angle is matched in advance, the complexity of the image transformation model can be reduced. The image alignment process can use a feature-based image registration method. Alignment is performed by adding feature line segments and feature points of the shooting angle, which greatly reduces the amount of calculation. For example, the scale-invariant feature transformation algorithm (ScaleInvariant Feature Transform, referred to as SIFT) can be used to determine the feature points of the image and the angle information of the feature points; for example, the line segment detector (LSD) can be used to extract the straight line characteristics of the image.

[0075] Image stitching and fusion are performed based on feature information to convert each pixel of the transformed image into the same image, and then the image fusion method is used to perform pixel fusion on the transition area of ​​the stitched image to optimize the image stitching quality.

[0076] The survey images of the installation area obtained in the above steps reflect the characteristics of the installation object and the surrounding environment objects from different angles. Compared with the prior art in which surveyors manually set marker points and aerial photography points for the installation area, the method of this embodiment uses three aerial photography to complete the entire survey task, designs the aerial photography plan with the help of the initial images obtained by the initial survey, and automatically completes the aerial photography task, which has a higher accuracy rate and reduces the dependence on the operation of the surveyors.

[0077] Step S202: Generate a 3D model based on the survey image. Figure 5 As shown, this step may include:

[0078] Step S501, discretize the survey image using set grid points to generate point cloud data of the installation area. One discretization method is: discretize using three-dimensional space grid points, and then sample a point in each grid point. Each small grid contains several points, and the point closest to the center point of the grid is taken as the discrete sampling point.

[0079] Step S502, using the point cloud data to construct a surface to obtain a surface model; the data captured by the drone can be processed to obtain sufficient point cloud data. Through surface construction, a surface model in the form of a point cloud can be obtained.

[0080] Step S503, perform object recognition on the survey image to determine the object boundary. The object recognition results include: installation objects (installation roofs, installation walls, vacant ground, etc.), basic objects of installation objects (installed building objects, walls, supports, etc.), surrounding environment objects, etc.

[0081] Step S504: compare the object boundary with the surface model and perform contour segmentation on the surface model.

[0082] Step S505, the surface model after contour segmentation is visualized to obtain a three-dimensional model. The specific visualization process may include: performing object entity processing on the surface model after contour segmentation to obtain contour surfaces of multiple objects; collecting color and pattern features of multiple objects in the survey image; performing appearance processing on the contour surfaces of multiple objects according to the color and pattern features to obtain a three-dimensional model of the installation area.

[0083] The final three-dimensional model of the installation area is similar to the actual visual state of the installation area, which is convenient for the construction owner of the photovoltaic system to intuitively understand the situation of the installation area. After obtaining the three-dimensional model of the installation area, it also includes: performing data statistics on the three-dimensional model to obtain data information of the three-dimensional model; assigning attribute information to multiple objects of the three-dimensional model. The data information of the three-dimensional model includes: coordinates, elevation data, area, length, height, slope, direction, etc., which can be read from the three-dimensional model. Object attribute information includes: project name, object type, etc.

[0084] Those skilled in the art will appreciate that generating a three-dimensional model by utilizing drone survey images can help improve modeling efficiency.

[0085] It should be noted that in some other embodiments, a manually drawn three-dimensional model may also be obtained.

[0086] Continue to refer to Figure 1 As shown in the figure, after obtaining the 3D model of the photovoltaic power station installation area:

[0087] Step S102, select equipment specification parameters from a preset equipment specification parameter library and perform photovoltaic power station layout design in a three-dimensional model to generate at least one candidate three-dimensional layout scheme. The equipment specification parameter library pre-stores multiple specification parameters of multiple equipment in a photovoltaic power station, and each specification parameter of each equipment includes multiple candidate parameters.

[0088] Specifically, the equipment of a photovoltaic power station includes photovoltaic panels, mounting brackets, and power distribution equipment. The power distribution equipment includes junction boxes or inverters, etc. Therefore, the equipment specification parameter library includes multiple specification parameters of photovoltaic panels, such as type (monocrystalline silicon panels, polycrystalline silicon panels, etc.), size, power, operating voltage and current, etc., multiple specification parameters of mounting brackets, such as the material of the mounting bracket (steel or aluminum alloy, etc.), size, shape and installation method (fixed bracket and tracking bracket), etc., and multiple specification parameters of power distribution equipment, such as current, voltage and power, etc. Each specification parameter of each device has multiple parameters to be selected. For example, there are many types and sizes of photovoltaic panels.

[0089] Reference Figure 6 As shown, this step includes:

[0090] Step S601, select one candidate parameter from each specification parameter of each device in turn to obtain a parameter set. That is, after obtaining the three-dimensional model of the installation area, the system automatically selects one of the multiple candidate parameters of the specification parameters of various devices of the photovoltaic power station from the preset device parameter library. For example, one is selected from multiple candidate types of photovoltaic panel type parameters, and one is selected from multiple candidate sizes of photovoltaic panel size parameters. Finally, all the selected parameters constitute the parameter set.

[0091] Step S602, generating a scheme to be verified according to the parameter set. Specifically, after all the specification parameters of various devices in the equipment specification parameter library are selected, the layout of the photovoltaic power station in the three-dimensional model can be carried out according to the parameter set composed of the selected parameters to obtain the three-dimensional model of the constructed photovoltaic power station, that is, the scheme to be verified.

[0092] Step S603, determine whether the scheme to be verified meets the preset design requirements. If so, execute step S604. If not, return to execute step S601 and obtain a new parameter set, thereby generating a new scheme to be verified. Specifically, after the scheme to be verified is generated, it is also necessary to verify indicators such as the cost and power generation of the scheme. Only when various indicators meet the preset design requirements can it be used as a photovoltaic power station scheme for construction. If the requirements are not met, it is necessary to redesign, that is, reselect parameters to form a new parameter set. The new parameter set is a set that has at least one parameter that is different from the previous parameter set. For a simple example, the photovoltaic panel in the previous parameter set is a monocrystalline silicon panel, and the new parameter set selects a polycrystalline silicon panel.

[0093] Step S604: The scheme to be verified is stored as a 3D layout scheme to be selected. If the scheme to be verified meets the preset design requirements, it can be stored as a 3D layout scheme to be selected and wait for subsequent output for selection.

[0094] Step S103: output all the three-dimensional layout solutions to be selected. Output the formed three-dimensional layout solution for selection.

[0095] In the scheme of this embodiment, after obtaining the three-dimensional model of the installation area, specification parameters are selected in the preset equipment specification parameter library to perform photovoltaic power station layout design in the three-dimensional model, thereby forming a candidate three-dimensional layout scheme, and finally outputting all the candidate three-dimensional layout schemes. In other words, the system can automatically select various specification parameters of various equipment in the photovoltaic power station for the photovoltaic power station layout design, thereby reducing the workload of users manually entering the specification parameters of photovoltaic power station equipment, effectively improving the degree of automation of photovoltaic power station design, and helping to improve design efficiency.

[0096] In addition, by detecting whether the scheme to be verified generated according to the parameter set meets the preset design requirements, that is, automatically verifying the scheme, thereby generating a candidate three-dimensional layout scheme that meets the preset design requirements, it helps to further improve the design efficiency.

[0097] like Figure 7 As shown, in one embodiment, for the step of selecting equipment specification parameters in a preset equipment specification parameter library and performing photovoltaic power station layout design in a three-dimensional model, the step of storing the scheme to be verified as a three-dimensional layout scheme to be selected includes: checking whether the preset conditions are met, if so, executing the step of outputting all the three-dimensional layout schemes to be selected, if not, then executing the step of selecting a candidate parameter from each specification parameter of each device in turn and obtaining a new parameter set.

[0098] Specifically, in this embodiment, the steps of selecting equipment specification parameters from a preset equipment specification parameter library and performing photovoltaic power station layout design in a three-dimensional model include:

[0099] Step S701 , selecting a candidate parameter from each specification parameter of each device in turn to obtain a parameter set.

[0100] Step S702: Generate a solution to be verified according to the parameter set.

[0101] Step S703, determine whether the scheme to be verified meets the preset design requirements, if so, execute step S704, if not, return to execute step S701, and obtain a new parameter set, thereby generating a new scheme to be verified.

[0102] Step S704: storing the scheme to be verified as a three-dimensional layout scheme to be selected.

[0103] Step S705, check whether the preset conditions are met, if so, execute step S706, if not, return to execute step S701 and obtain a new parameter set, thereby generating a new solution to be verified.

[0104] Specifically, the preset conditions include that the generated three-dimensional layout schemes to be selected have reached a preset number, or that all target sets that can be constituted by the candidate parameters in the device specification parameter library have generated schemes to be verified. The preset number is configured by the user and is greater than or equal to two. For example, it can be two, three, four, five or more. When the number of generated three-dimensional layout schemes to be selected is less than the preset number, new three-dimensional layout schemes to be selected continue to be generated until the preset number is reached. Alternatively, when all target sets that can be constituted by the candidate parameters in the device specification parameter library have generated schemes to be verified, that is, no new schemes to be verified can be generated, the next step is also performed.

[0105] Alternatively, the preset condition may also be receiving a signal to stop generating.

[0106] Step S706: output all candidate three-dimensional layout solutions.

[0107] In the scheme of this embodiment, after generating the candidate three-dimensional layout, it is checked whether the preset conditions are met. If the preset conditions are not met, a new candidate three-dimensional layout is continuously generated, so that multiple candidate three-dimensional layout schemes can be output for the user to choose from, thereby improving the flexibility of photovoltaic power station design and improving the user experience.

[0108] like Figure 8 As shown, in one embodiment, the device specification parameter library includes multiple specification parameters of photovoltaic panels, and the steps of selecting a candidate parameter from each specification parameter of each device in turn to obtain a parameter set include:

[0109] Step S801, firstly, a parameter to be selected is selected from various specification parameters of the photovoltaic panel to obtain a photovoltaic panel parameter set. In other words, the photovoltaic panel parameter set is obtained first.

[0110] Step S802, laying photovoltaic panels in the three-dimensional model according to the photovoltaic panel parameter set to obtain a photovoltaic panel layout. Specifically, after determining the photovoltaic panel parameter set, photovoltaic panels can be laid first to obtain a three-dimensional photovoltaic panel layout model with only photovoltaic panels.

[0111] Step S803, shadow analysis and power generation verification are performed on the photovoltaic panel layout. Specifically, although other equipment has not yet been determined, as long as the photovoltaic panels are laid, shadow analysis and discharge verification can be performed first, because they are only related to the specification parameters of the photovoltaic panels.

[0112] Step S804, whether the preset target requirements are met, if yes, execute step S805, if not, execute step S801, and obtain a new set of photovoltaic panel parameters. If the preset target requirements are not met, it means that the photovoltaic panel design parameters need to be changed, so a candidate parameter is selected from the various specification parameters of the photovoltaic panel to obtain a new set of photovoltaic panel parameters.

[0113] Step S805, continue to select parameters from each specification parameter of the remaining devices except the photovoltaic panel to obtain a parameter set. If the preset target requirements are met, the specification parameters of other devices can be further selected to finally form a parameter set of all devices.

[0114] In the scheme of this embodiment, a candidate parameter is first selected from various specification parameters of the photovoltaic panel to obtain a photovoltaic panel parameter set, photovoltaic panels are laid out in a three-dimensional model according to the photovoltaic panel parameter set to obtain a photovoltaic panel layout, shadow analysis and power generation verification are performed on the photovoltaic panel layout, and when the preset target requirements are met, candidate parameters are continuously selected from each specification parameter of the remaining equipment except the photovoltaic panel to obtain a parameter set. If the preset target requirements are not met, a candidate parameter is reselected from various specification parameters of the photovoltaic panel to obtain a new photovoltaic panel parameter set. In this way, the verification related to the photovoltaic panel can be carried out separately in advance. When the requirements are not met, only the specification parameters of the photovoltaic panel need to be reselected, which reduces the amount of repeated work to a certain extent and helps to improve design efficiency.

[0115] It should be noted that in this embodiment, when the scheme to be verified does not meet the preset design requirements, in the step of selecting a candidate parameter from each specification parameter of each device in turn and obtaining a new parameter set, the photovoltaic panel parameter set may remain unchanged, and the candidate parameter selected from each specification parameter of the remaining devices except the photovoltaic panel may be changed.

[0116] like Fig. 9 As shown, in one embodiment, the design method of a photovoltaic power station generally includes:

[0117] Step S901, obtaining a three-dimensional model of the photovoltaic power station installation area.

[0118] Step S902 , firstly, a parameter to be selected is selected from various specification parameters of the photovoltaic panel to obtain a photovoltaic panel parameter set.

[0119] Step S903, laying out photovoltaic panels on the three-dimensional model according to the photovoltaic panel parameter set to obtain a photovoltaic panel layout.

[0120] Step S904, performing shadow analysis and power generation verification on the photovoltaic panel layout.

[0121] Step S905, whether the preset target requirements are met, if so, execute step S906, if not, execute step S902, and obtain a new photovoltaic panel parameter set.

[0122] Step S906, continue to select parameters to be selected from each specification parameter of the remaining equipment except the photovoltaic panel to obtain a parameter set.

[0123] Step S907: Generate a solution to be verified according to the parameter set.

[0124] Step S908, determine whether the scheme to be verified meets the preset design requirements, if so, execute step S909, if not, return to execute step S902, and obtain a new parameter set, thereby generating a new scheme to be verified.

[0125] Step S909: storing the scheme to be verified as a three-dimensional layout scheme to be selected.

[0126] Step S910, check whether the preset conditions are met, if so, execute step S911, if not, return to execute step S902, and obtain a new parameter set, thereby generating a new solution to be verified.

[0127] Step S911, output all the three-dimensional layout schemes to be selected. In this step, the three-dimensional layout schemes to be selected with parameter sets are output. That is to say, all the three-dimensional layout schemes have original parameter set information, which can be displayed in a table form or a text file form. In this way, the user can better select a three-dimensional layout scheme that meets the design requirements according to the needs.

[0128] For details of the steps not described in detail in this embodiment, please refer to the above description.

[0129] After obtaining the three-dimensional model of the installation area, the specification parameters are selected in the preset equipment specification parameter library to design the layout of the photovoltaic power station in the three-dimensional model, thereby forming a candidate three-dimensional layout plan, and finally outputting all the candidate three-dimensional layout plans. In other words, the system can automatically select various specification parameters of various equipment in the photovoltaic power station for the photovoltaic power station layout design, thereby reducing the workload of users manually inputting the specification parameters of photovoltaic power station equipment, effectively improving the automation of photovoltaic power station design, and helping to improve design efficiency. After generating the candidate three-dimensional layout, check whether the preset conditions are met. If the preset conditions are not met, continue to generate a new candidate three-dimensional layout, so that multiple candidate three-dimensional layout plans can be output for users to choose in the end, thereby improving the flexibility of photovoltaic power station design and improving the user experience.

[0130] By first selecting a candidate parameter from the various specification parameters of the photovoltaic panel, a photovoltaic panel parameter set is obtained, and the photovoltaic panels are laid in the three-dimensional model according to the photovoltaic panel parameter set to obtain the photovoltaic panel layout, and the photovoltaic panel layout is subjected to shadow analysis and power generation verification. When the preset target requirements are met, the candidate parameters are continuously selected from each specification parameter of the remaining equipment except the photovoltaic panel to obtain a parameter set. If the preset target requirements are not met, a candidate parameter is reselected from the various specification parameters of the photovoltaic panel to obtain a new photovoltaic panel parameter set. In this way, the verification of the photovoltaic panel can be carried out separately in advance. When the requirements are not met, only the specification parameters of the photovoltaic panel need to be reselected, which reduces the repetitive workload to a certain extent and helps to improve the design efficiency.
