DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] The specific implementation of the above concept is described below.

[0021] Please refer to Figure 1 The embodiment of the present invention provides a photovoltaic panel layout optimization method for mountain photovoltaics, comprising: Project the mountain terrain data vertically onto a plane to obtain a terrain plane map; wherein each point in the terrain plane map is marked with the actual height of the point; Divide the terrain plan into multiple grid units, and calculate the height difference in each grid unit; wherein the height difference is the height difference between the point with the highest actual height and the point with the lowest actual height in the grid unit; The height difference of each grid cell is compared with the preset interval, and the grid cells with a height difference greater than the maximum value of the preset interval are marked as abandoned grids, the grid cells with a height difference within the preset interval are marked as modified grids, and the grid cells with a height difference less than the maximum value of the preset interval are marked as qualified grids; Determine the grid demand according to the number of pre-installed photovoltaic panels and the area of ​​the grid unit, select the grid demand grid units from the transformed grid and the qualified grid, traverse all possibilities, and obtain multiple different grid combinations; each grid combination includes the grid demand grid units; The best grid combination is selected from multiple grid combinations, and photovoltaic panels are laid out according to the best grid combination; if the grid combination includes a modified grid, construction is performed on the plots within the modified grid before laying the photovoltaic panels to improve the flatness of the plots within the modified grid.

[0022] In this embodiment, the three-dimensional surface data is projected and the three-dimensional surface is projected into a plane, that is, a topographic plane map. The topographic plane map is divided into a plurality of grid units, wherein the areas of the grid units are the same. Since the topographic plane map comes from the surface surface, after the projection is completed, the actual height of each point on the surface surface is retained, that is, each point in each grid unit in the topographic plane map is marked with the height of the corresponding point on the surface surface. The difference between the highest point and the lowest point in each grid unit is calculated and recorded as the height difference. The greater the height difference, the greater the ground undulations and the more uneven the actual surface position corresponding to the grid unit. The flatness of each grid unit is determined according to the height difference. If the height difference is less than the preset interval, the ground is relatively flat, and no construction modification is required, and photovoltaics can be directly laid out; if the height difference is within the preset interval, including falling at the end point of the preset interval, it is necessary to carry out construction modification to make the ground inside the grid flat before the photovoltaic panel layout is carried out; if the height difference exceeds the preset interval, the modification cost is too high, the construction platform is poor, and it is difficult to use. As mentioned above, each grid unit is marked and classified using the height difference to obtain qualified grids, modified grids and abandoned grids. Among them, qualified grids can be used directly, modified grids can be used after construction and modification, and abandoned grids cannot be used. After completing the marking and classification of the grid units, select appropriate grid units for the layout of photovoltaic panels. First, determine the required area based on the number of pre-laid photovoltaic panels, and then determine the required grid demand, that is, how many grid units are needed. There are multiple possibilities for selecting grid units with the required number of grids among multiple qualified grids and multiple modified grids. Traverse each possibility to obtain multiple grid combinations. Among the multiple grid combinations, select the optimal photovoltaic panel layout method that meets the needs according to the screening conditions.

[0023] In this embodiment, the preset interval can be calculated based on the area of ​​the grid unit and the preset angle interval. The preset angle interval is a slope interval suitable for transforming the slope into a flat surface, which can be 15°~25°.

[0024] In some embodiments of the present invention, screening the optimal grid combination from multiple grid combinations includes: For each grid combination, the following are performed: Calculate the construction costs of all the transformed grids in the grid combination; The grid combination with the lowest construction cost is selected as the optimal grid combination among all grid combinations.

[0025] In this embodiment, the screening condition may be construction cost. Specifically, the transformation of the grid requires surface earth excavation and other works, which will incur certain costs. The total cost of construction within the grid combination may be screened to select the grid combination with the lowest construction cost as the layout location of the photovoltaic panel.

[0026] In some embodiments of the present invention, the construction cost of each transformation grid is calculated as follows: The horizontal plane where the lowest point in the transformation grid is located is taken as the plane after transformation; Determine the rock composition of the upper strata of the transformed plane; Calculate the excavation and clearing construction cost of each type of rock in the upper stratum of the transformed plane, and sum them up to obtain the construction cost of the transformed grid.

[0027] In this embodiment, the sum of the excavation and cleaning construction costs of each modified grid in the grid combination is the construction cost of the grid combination. The modification of the modified grid is to excavate part of the rock soil in the modified grid to make its surface flat. In order to ensure that the ground of the modified grid is flat and stable after the modification, the plane where the point with the lowest altitude or actual height in the modified grid is located is selected as the reference, that is, the modified plane, and all the earthwork on the upper part of the modified plane is cleared. The upper earthwork of the modified plane may have one or more layers of strata, that is, there may be multiple rock layers. The physical and chemical properties of the rocks in each rock layer are different, so the cost caused by excavation and cleaning is different. The construction cost of each type of rock is calculated, and finally the construction cost of all types of rocks is summed up to obtain the construction cost of the modified grid.

[0028] In some embodiments of the present invention, the excavation and clearing construction cost of each type of rock is calculated as follows: M=V×q Among them, M is the construction cost of excavation and cleaning of a type of rock, f 1 is the function expression of the surface where the top layer of the rock is located, f 2 is the functional expression of the surface where the rock bottom layer is located, V is the volume of the rock, q is the construction cost per unit volume of the rock, x , y is the coordinate point on the rectangular coordinate system of the transformed plane.

[0029] In some embodiments of the present invention, f 1 and f 2Generated by mathematical software (such as MATLAB, Mathematica) or CAD tools (such as SolidWorks, Blender).

[0030] In this embodiment, a three-dimensional geological model can be generated by using geological data such as plan views and cross-section views collected in the field, and the data in the three-dimensional geological model is imported into the above software to generate f 1 and f 2.

[0031] In some embodiments of the present invention, screening the optimal grid combination from multiple grid combinations includes: Among multiple grid combinations, the grid combination with the most south slopes among multiple grid units is selected as the optimal grid combination.

[0032] In this embodiment, the screening condition may be the slope direction of the grid unit. According to the height change of the points in the grid unit, the main slope direction may be obtained, and the south slope with good lighting conditions may be selected for the layout of the photovoltaic panels.

[0033] In some embodiments of the present invention, screening the optimal grid combination from multiple grid combinations includes: Among multiple grid combinations, the grid combination with the most concentrated grid unit distribution is selected as the optimal grid combination.

[0034] In this embodiment, the photovoltaic panels need to be connected with cables, and the more concentrated the photovoltaic panels are, the more cables are saved. In addition, concentrated photovoltaic panels are also conducive to management and inspection.

[0035] Of course, the optimal photovoltaic panel layout can also be selected based on concentration, slope and cost. You only need to determine the weight coefficient of each factor and perform calculations.
