The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0051] Embodiment 1

[0052] According to an embodiment of the present invention, a photovoltaic power station planning method based on a tidal flat scenario is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in an order different from that shown here.

[0053] In this embodiment 1, a photovoltaic power station planning method based on a tidal flat scenario is provided, which can be used in electronic devices, such as computers. Figure 1 , Figure 1 A flowchart of a photovoltaic power station planning method based on a tidal flat scenario provided in the first embodiment of the present invention is shown, which specifically includes steps S01 to S04.

[0054] Step S01, obtaining a topographic image of a region to be planned, and determining a first region according to the topographic image and tidal factors.

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

[0056] In this embodiment, a historical geomorphic image of the area to be planned is obtained, and the tidal flat area and the tidal flat area in the historical geomorphic image are marked to obtain a marking result, wherein the marking can be performed manually, or the marking can be performed manually first, and the pixel range values ​​of the pixel points corresponding to the tidal flat area and the tidal flat area are respectively determined, and then the tidal flat area and the tidal flat area are automatically marked according to the corresponding pixel range values;

[0057] Acquire a geomorphic image of the area to be planned according to a preset period, and divide the tidal flat area and the tidal area in the geomorphic image according to the marking result, wherein the preset period can be determined by expert evaluation, and can be in hours or days. For example, one geomorphic image of the area to be planned is collected every day;

[0058] Determine the first area according to the changes of the divided tidal flat area and the tidal area, specifically, obtain a first pixel value of a first pixel point representing the tidal flat area and a second pixel value of a second pixel point representing the tidal area, wherein the first pixel value and the second pixel value may be pixel range values;

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

[0060] According to the second pixel value, a union process is performed on the tidal areas in the overlapped landform images, wherein, in the process of the union process, the pixel values ​​of the pixel points in the area where the tidal areas between the landform images intersect will be superimposed. It should be noted that there is a limit to the superposition of pixel values. Therefore, the number of all landform images collected when the tidal area is the smallest is obtained, and the pixel value size of a single superposition is determined according to the number and the pixel value range of the second pixel point, that is, the pixel value range of the second pixel point is divided by the number;

[0061] According to the first pixel value, intersection processing is performed on the tidal flat area in the overlapped landform image, wherein, during the intersection processing, the pixel value of the pixel point in the area where the tidal flat area between the landform images intersects is always the first pixel value;

[0062] When the tidal region is the smallest, the pixel superposition value of the pixel points to be processed by the union is obtained, and it is determined whether the pixel superposition value is less than a threshold value;

[0063] If it is determined that the pixel superposition value is less than the threshold, the pixel points whose pixel superposition value is less than the threshold are marked;

[0064] An area formed by the marked pixel points and the pixel points belonging to the first pixel value is determined as the first area.

[0065] Step S02, obtaining vegetation areas, wildlife habitat areas and migration areas of the area to be planned, and determining a target area in the first area according to the relationship between the vegetation areas, the wildlife habitat areas and the migration areas and the first area.

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

[0067] Determine whether the target vegetation area, the target wildlife habitat area, and the target migration area interfere with the first area, that is, determine whether the target vegetation area, the target wildlife habitat area, and the target migration area have an intersecting area with the first area;

[0068] If it is determined that the target vegetation area, the target wildlife habitat area, and the target migration area interfere with the first area, the first area is adjusted to obtain the target area. Specifically, according to the ecological importance, the target vegetation area, the target wildlife habitat area, and the target migration area are evaluated respectively to obtain corresponding scores, which can be determined after expert evaluation. In addition, the ecological importance can be considered based on biodiversity indicators, ecosystem service function value, ecosystem stability and resilience, ecosystem rarity and vulnerability, etc. Among them, the total score of the target vegetation area, the target wildlife habitat area, and the target migration area is the full score;

[0069] According to the grade standard, the corresponding subdivided areas in the target vegetation area, the target wildlife habitat area and the target migration area are scored to obtain the score of each subdivided area. For example, the subdivided areas of the target vegetation area can be distinguished according to the plant protection grade, the subdivided areas of the target wildlife habitat area can be distinguished according to the animal protection grade, and the corresponding subdivided areas in the target migration area can be distinguished according to the priority of the migration route;

[0070] According to the scores of each subdivided area, the first area is adjusted to obtain the target area. Specifically, according to the direction of light, the largest photovoltaic power station planning area in the first area is determined. It can be understood that in the northern hemisphere, photovoltaic panels are installed facing due south, wherein the optimal installation angle of photovoltaic panels is calculated according to the local latitude to maximize the amount of solar radiation received throughout the year. For example, when the local latitude is about 30°, the installation angle can be set between 28° and 32°. In addition, the shape of the planning area of ​​the photovoltaic power station is regular and neatly arranged. Generally, the photovoltaic power station forms a rectangular pattern as a whole. Therefore, according to the rectangular pattern, the largest photovoltaic power station planning area in the first area is determined;

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

[0072] If yes, determine the area of ​​the target vegetation area, the target wildlife habitat area, and the target migration area interfering with the largest PV power station planning area in the first area, and calculate the proportion of each interfering area in the corresponding subdivided area;

[0073] Determine the score of each interfering area according to the proportion of the area of ​​each interfering area in the corresponding subdivided area and the score of the corresponding subdivided area;

[0074] According to the scores of each interfered area and the minimum ecological score value, the corresponding interfered area is divided out from the first area to obtain the target area. For example, the total score of the target vegetation area, the target wildlife habitat area and the target migration area is 100 points, and the minimum ecological score value is 80 points. It can be understood that after the interfered area is finally divided out from the first area, the total score of the remaining target vegetation area, target wildlife habitat area and target migration area is not less than 80 points. It should be noted that priorities can be set for the vegetation area, wildlife habitat area and migration area, and the corresponding interfered area is divided out from the first area according to the order of priority.

[0075] Step S03, calculating the planned area of ​​the photovoltaic power station in the target area, and determining whether the planned area of ​​the photovoltaic power station is larger than a preset area, and if so, executing step S04.

[0076] Among them, a regular photovoltaic power station area is planned in the target area, and the area of ​​the photovoltaic power station area is calculated, and finally compared with the preset area.

[0077] Step S04: Push the planned area of ​​the photovoltaic power station to the user.

[0078] In summary, the photovoltaic power station planning method based on the tidal flat scene in the above-mentioned embodiment of the present invention obtains a topographic image of the area to be planned, and determines the first area according to the topographic image and tidal factors; obtains the vegetation area, wildlife habitat area and migration area of ​​the area to be planned, and determines the target area in the first area according to the relationship between the vegetation area, wildlife habitat area and 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 the preset area; if so, pushes the planned area of ​​the photovoltaic power station to the user, which can ensure the stability of the natural ecology and the healthy development of the photovoltaic power station.
