Description

Technical Field

[0001] This invention belongs to the field of photovoltaic power plant planning technology, and specifically relates to a photovoltaic power plant planning method and system based on tidal flat scenarios. Background Technology

[0002] Mudflats are a special type of landform found in coastal areas, mainly distributed near the coastline. They refer to flat or slightly sloping areas where the ocean meets the land, typically the junction of water and land.

[0003] Tidal flat areas possess unique geographical conditions. On the one hand, they have relatively vast and flat terrain, and often abundant sunshine resources, making them suitable for building photovoltaic power plants to utilize solar energy. However, tidal flat areas also present many challenges. Among them, the construction of photovoltaic power plants may disrupt the local ecological balance. Therefore, a balance needs to be struck between protecting the ecological environment and constructing photovoltaic power plants. Summary of the Invention

[0004] Based on this, the present invention provides a photovoltaic power station planning method and system based on tidal flat scenarios, which aims to assist in the planning of photovoltaic power stations and to achieve a balance between protecting the ecological environment and building photovoltaic power stations.

[0005] A first aspect of this invention provides a photovoltaic power plant planning method based on a tidal flat scenario, the method comprising:

[0006] Obtain a topographic image of the area to be planned, and determine the first area based on the topographic image and tidal factors;

[0007] Obtain the vegetation area, wildlife habitat area, and migration area of ​​the area to be planned; and determine the target area in the first area based on the relationship between the vegetation area, the wildlife habitat area, the migration area and the first area.

[0008] Calculate the planned area of ​​the photovoltaic power station in the target area, and determine whether the planned area of ​​the photovoltaic power station is greater than the preset area;

[0009] If so, the photovoltaic power station planning area will be pushed to the user.

[0010] Furthermore, the step of acquiring a geomorphic image of the area to be planned, and determining the first area based on the geomorphic image and tidal factors, includes:

[0011] Obtain historical geomorphological images of the area to be planned, and mark the tidal flat areas and tidal areas in the historical geomorphological images to obtain the marking results;

[0012] The geomorphic images of the area to be planned are acquired according to a preset cycle, and the tidal flat area and tidal area in the geomorphic images are divided according to the marking results.

[0013] The first area is determined based on the changes in the divided tidal flat areas and tidal areas.

[0014] Furthermore, the step of determining the first region based on the changes in the divided tidal flat area and tidal area includes:

[0015] Obtain the first pixel value of the first pixel representing the tidal flat area and the second pixel value of the second pixel representing the tidal area;

[0016] Overlay all the topographic images of the area to be planned in chronological order;

[0017] Based on the second pixel value, the tidal regions in the overlapping landform images are subjected to union processing. During the union processing, the pixel values ​​of the pixels in the areas where the tidal regions of the landform images intersect are superimposed.

[0018] Based on the first pixel value, the tidal flat areas in the overlapping landform images are subjected to intersection processing. During the intersection processing, the pixel value of the pixel point in the area where the tidal flat areas of the landform images intersect is always the first pixel value.

[0019] When the tidal region area is at its minimum, obtain the pixel superposition value of the pixels to be processed by union, and determine whether the pixel superposition value is less than the threshold.

[0020] If it is determined that the pixel superposition value is less than the threshold, then the pixels whose pixel superposition value is less than the threshold are marked.

[0021] The region formed by the marked pixel and the pixel belonging to the first pixel value is defined as the first region.

[0022] Furthermore, in the step of superimposing the pixel values ​​of pixels in the overlapping areas of tidal regions between terrain images during the union processing, the number of all collected terrain images when the tidal region area is the smallest is obtained, and the size of the pixel value for a single superposition is determined based on the number and the pixel value range of the second pixel.

[0023] Furthermore, the step of obtaining the vegetation area, wildlife habitat area, and migration area of ​​the area to be planned, and determining the target area in the first area based on the relationship between the vegetation area, the wildlife habitat area, the migration area, and the first area includes:

[0024] Obtain the current vegetation area, wildlife habitat area, and migration area of ​​the area to be planned, and predict the target vegetation area, target wildlife habitat area, and target migration area based on the historical changes of the current vegetation area, wildlife habitat area, and migration area of ​​the area to be planned.

[0025] Determine whether the target vegetation area, the target wildlife habitat area, and the target migration area interfere with the first area;

[0026] If it is determined that the target vegetation area, the target wildlife habitat area, and the target migration area interfere with the first area, then the first area is adjusted to obtain the target area.

[0027] Furthermore, the step of adjusting the first region to obtain the target region includes:

[0028] Based on their ecological importance, the target vegetation area, target wildlife habitat area, and target migration area are assessed separately to obtain corresponding scores. The sum of the scores for the target vegetation area, target wildlife habitat area, and target migration area is the full score.

[0029] According to the grading standards, the corresponding sub-regions of the target vegetation area, target wildlife habitat area and target migration area are scored to obtain the score of each sub-region;

[0030] Based on the scores of each sub-region, the first region is adjusted to obtain the target region.

[0031] Furthermore, the step of adjusting the first region based on the scores of each sub-region to obtain the target region includes:

[0032] Based on the direction of sunlight, determine the largest planned area for a photovoltaic power station in the first region;

[0033] Determine whether the target vegetation area, target wildlife habitat area, and target migration area interfere with the largest photovoltaic power station planning area in the first area;

[0034] If so, determine the area of ​​interference between the target vegetation area, the target wildlife habitat area, and the target migration area and the largest photovoltaic power station planning area in the first area, and calculate the proportion of each interfering area in the corresponding sub-area;

[0035] The score of each interference region is determined based on the proportion of the area of ​​each interference region in the corresponding sub-region and the score of the corresponding sub-region.

[0036] Based on the scores of each interfering region and the minimum ecological score, the corresponding interfering region is separated from the first region to obtain the target region.

[0037] A second aspect of this invention provides a photovoltaic power plant planning system based on a tidal flat scenario, used to implement the photovoltaic power plant planning method based on a tidal flat scenario provided in the first aspect, the system comprising:

[0038] The first determining module is used to acquire a geomorphic image of the area to be planned, and determine the first area based on the geomorphic image and tidal factors;

[0039] The second determining module is used to acquire the vegetation area, wildlife habitat area and migration area of ​​the area to be planned, and determine the target area in the first area based on the relationship between the vegetation area, the wildlife habitat area and the migration area and the first area.

[0040] The judgment module is used to calculate the planned area of ​​the photovoltaic power station in the target area and determine whether the planned area of ​​the photovoltaic power station is greater than a preset area.

[0041] The push module is used to push the planned area of ​​the photovoltaic power station to the user when it is determined that the planned area of ​​the photovoltaic power station is greater than the preset area.

[0048] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of the invention are illustrated in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0050] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0051] Example 1

[0052] According to an embodiment of the present invention, a photovoltaic power plant planning method based on a tidal flat scenario 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.

[0053] This first embodiment provides a photovoltaic power plant planning method based on a tidal flat scenario, which can be used in electronic devices, such as computers. Please refer to... Figure 1 , Figure 1 The flowchart of a photovoltaic power plant planning method based on a tidal flat scenario provided in Embodiment 1 of the present invention is shown, specifically including steps S01 to S04.

[0054] Step S01: Obtain a geomorphic image of the area to be planned, and determine the first area based on the geomorphic image and tidal factors.

[0055] Specifically, the topographic images of the area to be planned can be obtained through satellite remote sensing, drone mapping, or a combination of these methods. Understandably, since the tidal flats are close to the water, they will be affected by tides, and the actual area of ​​the tidal flats will change. It should be noted that the brackets of the photovoltaic panels are immersed in water with high salinity for a long time, which makes them prone to rust and damage. Therefore, it is necessary to plan the construction area of ​​the photovoltaic power station in a reasonable way so that the brackets can spend less time in the water.

[0056] In this embodiment, historical geomorphological images of the area to be planned are obtained, and the tidal flat areas and tidal areas in the historical geomorphological images are marked to obtain the marking results. The marking can be done manually, or the marking can be done manually first to determine the pixel range values ​​of the corresponding pixels in the tidal flat areas and tidal areas, and then the tidal flat areas and tidal areas are automatically marked according to the corresponding pixel range values.

[0057] The geomorphic images of the area to be planned are acquired according to a preset cycle. Based on the marking results, the tidal flat area and tidal area in the geomorphic images are divided. The preset cycle can be determined by expert evaluation and can be in the unit of hours or days. For example, one geomorphic image of the area to be planned is collected every day.

[0058] Based on the changes in the divided tidal flat area and tidal area, the first area is determined. Specifically, the first pixel value of the first pixel point representing the tidal flat area and the second pixel value of the second pixel point representing the tidal area are obtained. The first pixel value and the second pixel value can be pixel range values.

[0059] Overlay all the topographic images of the area to be planned in chronological order;

[0060] Based on the second pixel value, the tidal regions in the overlapping terrain images are subjected to union processing. During the union processing, the pixel values ​​of the pixels in the overlapping tidal regions of the terrain images will be superimposed. It should be noted that there is a limit to the superposition of pixel values. Therefore, the number of all terrain images collected when the tidal region area is the smallest is obtained, and the size of the pixel value for a single superposition is determined based on the number and the pixel value range of the second pixel, that is, the pixel value range of the second pixel is divided by the number.

[0061] Based on the first pixel value, the tidal flat areas in the overlapping landform images are subjected to intersection processing. During the intersection processing, the pixel value of the pixel in the area where the tidal flat areas of the landform images intersect is always the first pixel value.

[0062] When the tidal region area is at its minimum, obtain the pixel superposition value of the pixels to be processed by union, and determine whether the pixel superposition value is less than the threshold.

[0063] If the pixel overlap value is determined to be less than the threshold, then the pixels with pixel overlap values ​​less than the threshold are marked.

[0064] The region formed by the marked pixels and the pixels belonging to the first pixel value is defined as the first region.

[0065] Step S02: Obtain the vegetation area, wildlife habitat area, and migration area of ​​the area to be planned. Based on the relationship between the vegetation area, the wildlife habitat area, the migration area, and the first area, determine the target area in the first area.

[0066] Specifically, the current vegetation areas, wildlife habitat areas, and migration areas of the area to be planned are obtained. Based on the historical changes of the current vegetation areas, wildlife habitat areas, and migration areas of the area to be planned, the target vegetation areas, target wildlife habitat areas, and target migration areas are predicted. It should be noted that the prediction of the target vegetation areas, target wildlife habitat areas, and target migration areas can be made by expert evaluation based on historical changes, or by big data models.

[0067] Determine whether the target vegetation area, target wildlife habitat area, and target migration area interfere with the first area, that is, determine whether the target vegetation area, target wildlife habitat area, and target migration area intersect with the first area.

[0068] If the target vegetation area, target wildlife habitat area, and target migration area are determined to interfere with the first area, the first area is adjusted to obtain the target area. Specifically, the target vegetation area, target wildlife habitat area, and target migration area are assessed separately according to their ecological importance, and corresponding scores are obtained. These scores can be determined by experts. In addition, the ecological importance can be considered from multiple aspects such as biodiversity indicators, ecosystem service function value, ecosystem stability and resilience, ecosystem rarity and vulnerability. The sum of the scores of the target vegetation area, target wildlife habitat area, and target migration area is the full score.

[0069] According to the grading standards, the target vegetation area, target wildlife habitat area, and target migration area are scored to obtain the score of each sub-area. For example, the sub-areas of the target vegetation area can be distinguished according to the plant protection level, the sub-areas of the target wildlife habitat area can be distinguished according to the animal protection level, and the sub-areas of the target migration area can be distinguished according to the priority of the migration route.

[0070] Based on the scores of each sub-region, the first region is adjusted to obtain the target region. Specifically, based on the direction of sunlight, the largest planned photovoltaic power station area in the first region is determined. Understandably, in the Northern Hemisphere, photovoltaic panels are installed facing due south. The optimal installation angle of the photovoltaic panels is calculated based on the local latitude to maximize the annual solar radiation reception. For example, when the local latitude is around 30°, the installation angle can be set between 28° and 32°. Furthermore, the planned area for a photovoltaic power station is regular in shape and neatly arranged; generally, a photovoltaic power station forms a rectangular pattern. Therefore, based on this rectangular pattern, the largest planned photovoltaic power station area in the first region is determined.

[0071] Determine whether the target vegetation area, target wildlife habitat area, and target migration area interfere with the largest photovoltaic power station planning area in the first region, that is, determine whether the target vegetation area, target wildlife habitat area, and target migration area intersect with the largest photovoltaic power station planning area in the first region.

[0072] If so, determine the area of ​​interference between the target vegetation area, the target wildlife habitat area, and the target migration area and the largest photovoltaic power station planning area in the first area, and calculate the proportion of each interference area in the corresponding sub-area.

[0073] The score of each interference region is determined based on the proportion of the area of ​​each interference region in the corresponding sub-region and the score of the corresponding sub-region.

[0074] Based on the scores of each interfering region and the minimum ecological score, the corresponding interfering region is separated from the first region to obtain the target region. For example, the total score of the target vegetation region, target wildlife habitat region, and target migration region is 100 points, and the minimum ecological score is 80 points. Understandably, after separating the interfering regions from the first region, the total score of the remaining target vegetation region, target wildlife habitat region, and target migration region is not less than 80 points. It should be noted that the vegetation region, wildlife habitat region, and migration region can be prioritized, and the corresponding interfering region is separated from the first region according to the priority order.

[0075] Step S03: Calculate the planned area of ​​the photovoltaic power station in the target area, and determine whether the planned area of ​​the photovoltaic power station is greater than the preset area. If so, proceed to step S04.

[0076] This involves planning regular photovoltaic power station areas within the target region, calculating the area of ​​these areas, and finally comparing it with a preset area.

[0077] Step S04 then pushes the photovoltaic power station planning area to the user.

[0078] In summary, the photovoltaic power station planning method based on tidal flat scenarios in the above embodiments of the present invention obtains a geomorphic image of the area to be planned, determines a first area based on the geomorphic image and tidal factors, obtains the vegetation area, wildlife habitat area, and migration area of ​​the area to be planned, determines a target area within the first area based on the relationship between the vegetation area, wildlife habitat area, migration area, and the first area, calculates the planned area of ​​the photovoltaic power station in the target area, and determines whether the planned area of ​​the photovoltaic power station is greater than a preset area; if so, the planned area of ​​the photovoltaic power station is pushed to the user, which can ensure the stability of the natural ecology and the healthy development of the photovoltaic power station.
