The present embodiment and the following embodiments will be described below by taking the photovoltaic module arrangement apparatus as an example.
It should be understood that the area to be arranged refers to an area where the photovoltaic module arrangement is required, for example, a roof, a slope, etc. The obstacle may generate an obstacle shadow, which refers to a shadow generated by the obstacle on the area to be arranged, for example, a shadow generated by an obstacle such as a telegraph pole, a chimney, and the like. Initial shading refers to: if the shadow change of an obstacle at different moments is small, namely the shadow area, the shadow range and the like are not basically changed along with the change of time, the shadow set of the obstacle at different moments is used as the initial shadow of the obstacle; the initial shadow set refers to a set of initial shadows of all obstacles in the arrangement area; changing shadows refers to: if the shadow of one obstacle changes greatly at different moments, namely the shadow area, the shadow range and the like change along with the change of time, the shadow set of the obstacle at different moments is used as the changed shadow of the obstacle; the shadow changing set refers to a set of changing shadows of all barriers in the arrangement area; the obstacle shadow set refers to a set of an initial shadow set and a changed shadow set.
Step S20: and determining initial arrangement points of the photovoltaic modules according to the initial shadow set and a preset shielding ratio, and determining an initial photovoltaic module arrangement scheme according to the initial arrangement points.
It is understood that the photovoltaic module refers to a photovoltaic module that is arranged on an area to be arranged, and the size, the capacity, and the like of the photovoltaic module are not particularly limited in this embodiment. The preset shielding ratio may be a threshold value set in advance according to actual conditions, for example, 30%, 35%, or the like, which is not particularly limited in the present embodiment.
It should be understood that the initial arrangement point refers to an arrangement starting point of the photovoltaic modules, that is, the photovoltaic modules are arranged on the area to be arranged with the initial arrangement point as the starting point, so as to obtain an initial photovoltaic module arrangement scheme. Specifically, an initial arranging point of the photovoltaic module can be determined according to an initial shadow set and a preset shielding ratio, the ratio of the area shielded by the shadow to the module area is calculated according to the initial shadow set when the photovoltaic module moves once, and the position can be used as the initial arranging point when the ratio is smaller than the preset shielding ratio.
Further, in order to accurately obtain the initial arrangement point, in this embodiment, the step of determining the initial arrangement point of the photovoltaic module according to the initial shadow set and the preset shielding ratio specifically includes: selecting a preset initial arrangement point on the area to be arranged according to a preset rule; arranging an initial photovoltaic module by taking the preset initial arranging point as a starting point, and determining a shadow area on the initial photovoltaic module according to the initial shadow set; determining the shielding ratio of the initial photovoltaic module according to the shadow area, and comparing the shielding ratio with a preset shielding ratio; and if the shielding ratio is greater than the preset shielding ratio, returning to execute the step of selecting the preset initial arranging point on the area to be arranged until the shielding ratio of the initial photovoltaic module is less than or equal to the preset shielding ratio, and taking the selected preset initial arranging point as the initial arranging point.
It can be understood that referring to fig. 3, fig. 3 is a schematic diagram of an area to be arranged and an initial shadow set according to an embodiment of the photovoltaic module arranging method of the present invention. As shown in fig. 3, the entire quadrangle hijk may be represented as an area to be arranged, and the hatched portion may be represented as an initial shadow set, which is shown in fig. 3 as an example only, and may be an irregular shadow, or a plurality of initial shadows. The quadrilateral abgf may be represented as an initial photovoltaic module.
It should be understood that a preset initial arrangement point may be selected on the area to be arranged according to a preset rule, where the preset rule may be that an edge point on the area to be arranged is selected as a preset initial arrangement point, for example, any point in h, i, j, k in fig. 3, and the initial photovoltaic module is arranged with the preset initial arrangement point as a starting point, that is, the vertex of the initial photovoltaic module coincides with the preset initial arrangement point, for example, the point a of the initial photovoltaic module coincides with the point h of the area to be arranged in fig. 3, so that a shadow area on the initial photovoltaic module under the preset initial arrangement point may be obtained, where the shadow area may be an area occupied by the initial shadow set on the initial photovoltaic module, and the shielding ratio of the initial photovoltaic module is a ratio between the shadow area and the area of the initial photovoltaic module, and compares the shielding ratio with the preset shielding ratio.
It can be understood that if the shielding ratio of the initial photovoltaic module under the preset initial arranging point is greater than the preset shielding ratio, the preset initial arranging point can be selected again, and the preset initial arranging point can be moved according to the preset direction and the preset distance, for example, the preset initial arranging point is moved rightward and downward, firstly moved rightward by 0.1 meter, then moved downward by 0.1 meter, then moved rightward by 0.1 meter, and the like, and the embodiment does not limit the preset direction or the preset distance. Therefore, in the moving process of the preset initial arranging points, the shielding ratio of the initial photovoltaic modules under different preset initial arranging points can be obtained, if the shielding ratio is smaller than the preset shielding ratio, the preset initial arranging points can be used as the initial arranging points, and it can be understood that another scheme for moving the preset initial arranging points exists simultaneously, namely, the initial arranging points move downwards and then move rightwards, when the preset initial arranging points are moved in the mode, the shielding ratio of the initial photovoltaic modules under different preset initial arranging points can be obtained, if the shielding ratio is smaller than the preset shielding ratio, the preset initial arranging points can be used as the initial arranging points, and if two preset initial arranging points meeting the conditions exist simultaneously, and the two preset initial arranging points do not coincide, the arrangement modules are arranged by taking the points as the initial arranging points, so that a plurality of initial photovoltaic module arrangement schemes are obtained; if the two preset initial arrangement points are overlapped, an initial photovoltaic module arrangement scheme is obtained.
In a specific implementation, assuming that the h point in fig. 3 is taken as a preset initial arranging point, firstly calculating the shielding ratio of the point at the upper left of the initial photovoltaic module under the condition that the point a and the h point coincide, and if the shielding ratio is smaller than the preset shielding ratio, selecting the h point as the initial arranging point. If the shielding ratio is greater than the preset shielding ratio, taking a point from the h point to the next unit as a preset initial arrangement point, arranging the initial photovoltaic assembly on the preset initial arrangement point, namely, overlapping the vertex of the initial photovoltaic assembly with the preset initial arrangement point, calculating the shielding ratio of the initial photovoltaic assembly, if the shielding ratio is less than or equal to the preset shielding ratio, stopping calculation, taking the preset initial arrangement point meeting the condition as the initial arrangement point, if the shielding ratio is greater than the preset shielding ratio, re-selecting the preset initial arrangement point, taking the point from the preset initial arrangement point to the right as a new preset initial arrangement point, calculating the shielding ratio of the initial photovoltaic assembly, if the shielding ratio is less than or equal to the preset shielding ratio, stopping calculation, taking the preset initial arrangement point meeting the condition as the initial arrangement point, if the shielding ratio is greater than the preset shielding ratio, re-selecting the preset initial arrangement point, taking the preset initial arrangement point meeting the condition as the initial arrangement point, re-selecting the new preset initial arrangement point, and carrying out one downward calculation on the new preset initial arrangement point as the new preset initial arrangement point, and carrying out one downward calculation on the initial arrangement point, and one downward unit, thus obtaining a downward unit in a downward calculation process. Besides the scheme of selecting the preset initial arrangement point, the point which is one unit to the right from the h point can be selected as the preset initial arrangement point, the initial photovoltaic module is arranged on the preset initial arrangement point, namely, the vertex of the initial photovoltaic module is overlapped with the preset initial arrangement point, the shielding ratio of the initial photovoltaic module is calculated, if the shielding ratio is smaller than or equal to the preset shielding ratio, the condition is met, the calculation is stopped, the preset initial arrangement point which meets the condition is taken as the initial arrangement point, if the shielding ratio is larger than the preset shielding ratio, the preset initial arrangement point is selected again, the point which is one unit to the right from the preset initial arrangement point is selected as the new preset initial arrangement point, the shielding ratio of the initial photovoltaic module is calculated, if the shielding ratio is smaller than or equal to the preset shielding ratio, the condition is met, the calculation is stopped, the preset initial arrangement point which meets the condition is taken as the initial arrangement point, if the shielding ratio is larger than the preset shielding ratio, the preset initial arrangement point is selected again, the point which is one unit to the right from the new preset initial arrangement point is selected, and the unit to the right is calculated, and the unit to the right is sequentially arranged in the process. If the initial arrangement points obtained in the two modes are not coincident, two initial arrangement points are obtained, and then two initial arrangement schemes are obtained; if the initial arrangement points obtained in the two modes coincide, an initial arrangement scheme can be obtained.
Step S30: and optimizing the photovoltaic module arrangement in the initial photovoltaic module arrangement scheme according to the initial shadow set and the changed shadow set to obtain a target photovoltaic module arrangement scheme.
It can be appreciated that, in this embodiment, the photovoltaic module arrangement in the initial photovoltaic module arrangement scheme may be optimized according to the initial shadow set and the changed shadow set, and specifically, the photovoltaic modules meeting the preset conditions may be deleted according to the comparison between the area occupied by the shadow photovoltaic module by the obstacle shadow set and the area of the shadow photovoltaic module, so as to obtain the optimized module arrangement scheme. It can be appreciated that if there are a plurality of initial photovoltaic module arrangements, the plurality of initial photovoltaic module arrangements are optimized, respectively, and then a target photovoltaic module arrangement is selected from the plurality of optimized module arrangements.
According to the method, the device and the system, the initial shadow set and the changed shadow set of the obstacle shadows on the area to be arranged are determined, then the initial arrangement points of the photovoltaic modules are determined according to the initial shadow set and the preset shielding ratio, the initial photovoltaic module arrangement scheme is determined according to the initial arrangement points, and then the photovoltaic module arrangement in the initial photovoltaic module arrangement scheme is optimized according to the initial shadow set and the changed shadow set, so that the target photovoltaic module arrangement scheme is obtained. According to the method, the initial shadow set and the changed shadow set of the obstacle on the area to be arranged can be determined, the initial shadow set with small change and the changed shadow set with large change corresponding to the obstacle can be determined, then the initial arranging point is determined according to the initial shadow set and the preset shielding ratio, the starting point of photovoltaic module arrangement can be determined, the initial photovoltaic module arrangement scheme is determined according to the initial arranging point, photovoltaic module arrangement in the initial photovoltaic module arrangement scheme is optimized according to the initial shadow set and the changed shadow set, compared with the existing simple superposition of the shadow area of the obstacle, the initial arranging point can be determined according to the initial shadow set and the preset shielding ratio, photovoltaic module arrangement is effectively carried out according to the initial arranging point, and photovoltaic module arrangement optimization is carried out according to the initial shadow set changed shadow set.

step S101: and determining the obstacle on the area to be arranged.
Step S102: and determining the shadow of each obstacle at different moments, and selecting the maximum shadow and the close shadow of the obstacle from the shadows.

It should be understood that referring to fig. 5, fig. 5 is a schematic diagram of maximum shadows and similar shadows according to an embodiment of the photovoltaic module arrangement method of the present invention. As shown in fig. 5, when the obstacle is a utility pole, shade 1, abfh, can be the maximum obstacle shade; shadow 2, cdig, can be considered a similar shadow.
Step S103: a rate of change of the obstacle is determined based on the maximum shadow and the proximate shadow.
It is understood that the change ratio refers to the change condition of the shadow of the obstacle, and the smaller the change ratio, the smaller the change degree of the shadow of the obstacle is, and the change ratio can be specifically determined according to the maximum shadow and the close shadow of the obstacle.
Further, in order to accurately determine the change ratio corresponding to the obstacle, in the present embodiment, the step S103 includes: determining a maximum shadow area corresponding to the maximum shadow; determining cross shadows between the maximum shadows and the similar shadows, and determining cross shadow areas corresponding to the cross shadows; and determining an unchanged ratio and a changed ratio of the obstacle according to the cross-hatched area and the maximum hatched area.

Referring to fig. 6, fig. 6 is a schematic flow chart of a third embodiment of the photovoltaic module arrangement method of the present invention.
Based on the above embodiments, in this embodiment, the step S30 includes:
step S301: and performing primary optimization on the photovoltaic module arrangement in the initial photovoltaic module arrangement scheme according to the initial shadow set to obtain a primary optimized photovoltaic module arrangement scheme.
It can be understood that the photovoltaic module arrangement in the initial photovoltaic module arrangement scheme can be optimized for the first time according to the initial shadow set, and particularly the photovoltaic module with larger shielding ratio corresponding to the initial shadow set can be deleted to obtain the photovoltaic module arrangement scheme after the first time optimization.
Further, in this embodiment, the step S301 includes: determining each initial shadow photovoltaic module in the initial photovoltaic module arrangement scheme according to the initial shadow set; determining an initial shielding ratio corresponding to each initial shadow photovoltaic module, and comparing the initial shielding ratio with a preset shielding ratio; if the initial shielding ratio is larger than the preset shielding ratio, deleting the initial shadow photovoltaic module to obtain a photovoltaic module arrangement scheme after primary optimization; and if the initial shielding ratio is smaller than or equal to the preset shielding ratio, reserving the initial shadow photovoltaic module to obtain a photovoltaic module arrangement scheme after primary optimization.
It should be understood that an initial shadow photovoltaic module refers to a module covered by an initial shadow set in an initial photovoltaic module arrangement. The initial shielding ratio refers to the ratio between the area occupied by the initial shadow on the initial shadow photovoltaic module and the module area, and the initial shielding ratio is compared with the preset shielding ratio.
In a specific implementation, when the initial shielding ratio is greater than the preset shielding ratio, the corresponding initial shadow photovoltaic module can be deleted to obtain a photovoltaic module arrangement scheme after primary optimization, and when the initial shielding ratio is less than or equal to the preset shielding ratio, the corresponding initial shadow photovoltaic module can be reserved to obtain the photovoltaic module arrangement scheme after primary optimization.
Step S302: and determining each shadow-changing photovoltaic module in the initially optimized photovoltaic module arrangement scheme according to the shadow-changing set.
It is understood that the shadow-changing photovoltaic module refers to a module covered by a shadow-changing set in the initial photovoltaic module arrangement scheme.
Step S303: for each variable shade photovoltaic module, determining an average shielding ratio corresponding to the variable shade photovoltaic module, and comparing the average shielding ratio with a preset shielding ratio.
It should be understood that each variable shade photovoltaic module corresponds to an average shielding ratio, the average shielding ratio may be an average value of the shielding ratios of the variable shade photovoltaic module at each time, the shielding ratio may be a ratio between an area of a shade on the variable shade photovoltaic module and an area of the variable shade photovoltaic module at any time, and the average shielding ratio is compared with a preset shielding ratio.
Further, in order to accurately determine the average shielding ratio corresponding to the changed shadow photovoltaic module, in this embodiment, the step of determining the average shielding ratio corresponding to the changed shadow photovoltaic module specifically includes: determining the shadow area of the shadow-changing photovoltaic module at each moment in a preset time period according to the initial shadow set and the shadow-changing set; and determining an average shadow area according to each shadow area, and determining an average shielding ratio according to the average shadow area.
It is to be understood that the present embodiment may determine the shadow area at each time within a preset time period, and the preset time period may be a preset time period, for example, 9 to 15 points, 9 to 16 points, and the like, which is not particularly limited in the present embodiment. The shadow area refers to the area occupied by the initial shadow and the changed shadow in the changed shadow photovoltaic module at each moment in the preset time period, the average shadow area refers to the average value of the shadow areas of the changed shadow photovoltaic module in the preset time period, and the average shielding ratio refers to the ratio between the average shadow area and the module area.
In a specific implementation, referring to fig. 7, fig. 7 is a schematic view of shadows according to an embodiment of the photovoltaic module arrangement method of the present invention. As shown in fig. 7, assuming that the shadow 1, abhf, and the shadow 2, cdig, corresponding to the obstacle as the telegraph pole are obtained in the preset time period, the shadow 1 and the shadow 2 are initial shadows and changed shadows at different moments, the component with the side jk is the changed shadow photovoltaic component, the area occupied by the shadow 1 on the photovoltaic component and the area occupied by the shadow 2 on the photovoltaic component can be determined, and then the average value of the two areas is divided by the component area, so that the obtained ratio is taken as the average shielding frequency.
Step S304: and if the average shielding ratio is larger than the preset shielding ratio, deleting the shade-changed photovoltaic module to obtain an optimized photovoltaic module arrangement scheme.
It should be appreciated that when the average shielding ratio is greater than the preset shielding ratio, the corresponding shadow photovoltaic modules may be deleted to obtain an optimized photovoltaic module arrangement scheme.
Step S305: and if the average shielding ratio is smaller than or equal to the preset shielding ratio, reserving the shade-changed photovoltaic module to obtain an optimized photovoltaic module arrangement scheme.
It can be appreciated that when the average shielding ratio is less than or equal to the preset shielding ratio, the corresponding shadow photovoltaic modules can be reserved, and an optimized photovoltaic module arrangement scheme is obtained.
Step S306: and determining a target photovoltaic module arrangement scheme according to the optimized photovoltaic module arrangement scheme.
In a specific implementation, when the photovoltaic module arrangement scheme is only one, the optimized photovoltaic module arrangement scheme can be used as a target photovoltaic module arrangement scheme. When the photovoltaic module arrangement schemes are multiple, the multiple photovoltaic module schemes are required to be optimized respectively, and then a target photovoltaic module arrangement scheme is selected from the multiple optimized photovoltaic module arrangement schemes.
Further, in order to effectively select the target photovoltaic module arrangement from the plurality of optimized photovoltaic module arrangements, in this embodiment, the step S305 includes: if the photovoltaic module arrangement scheme is one, directly determining that the optimized photovoltaic module arrangement scheme is a target photovoltaic module arrangement scheme; and if the optimized photovoltaic module arrangement schemes are multiple, obtaining module capacities corresponding to the optimized photovoltaic module arrangement schemes, and selecting a target photovoltaic module arrangement scheme from the optimized photovoltaic module arrangement schemes according to the maximum value in the module capacities.
It should be understood that, since the preset directions when the preset initial arrangement points are obtained in this embodiment may be set to be multiple, the obtained initial photovoltaic module arrangement schemes may be also multiple, and the corresponding optimized photovoltaic module arrangement schemes may also be multiple, for example, two translation directions exist at the h point in fig. 3, one translates to the i point, and one translates to the k point, that is, the two schemes are calculated separately. One is to translate the calculation to the i point first, and one is to translate the calculation to the k point first. The first direction is translation to i, and the next translation direction is translation to k; conversely, the first direction is to translate toward k first, and the next translation direction is to translate toward i. According to the direction of the first translation, the two directions are respectively named as an i-direction scheme and a k-direction scheme. It is possible that two schemes obtain two different initial arrangement points, i.e. two initial photovoltaic module arrangement schemes can be obtained.
It can be understood that when the optimized photovoltaic module arrangement schemes are multiple, the module capacity corresponding to each optimized photovoltaic module arrangement scheme can be obtained, the module capacity can be related to the number of modules and the module model, and the specific mode of determining the module capacity can refer to the prior art, which is not repeated in this embodiment. And selecting a photovoltaic module arrangement scheme from the optimized photovoltaic module arrangement schemes according to the module capacity, wherein the optimized photovoltaic module arrangement scheme with the largest module capacity can be specifically selected as a target photovoltaic module arrangement scheme.
Further, in order to determine the final photovoltaic module arrangement scheme, in this embodiment, after step S30, the method further includes: determining a target photovoltaic module arrangement scheme under different preset shielding ratios; determining component capacity profits and component costs under each target photovoltaic component arrangement scheme, and determining target profits according to the component capacity profits and the component costs; and selecting a photovoltaic module arrangement scheme from the target photovoltaic module arrangement schemes according to the target profit.
It can be understood that the preset shielding ratio in this embodiment may include a plurality of preset shielding ratios, and specifically may be set to any value from 0% to 100%, so that initial arrangement points of the photovoltaic modules under different preset shielding ratios can be obtained, and then a target photovoltaic module arrangement scheme under different preset shielding ratios is obtained.
It should be understood that different projects have different requirements, different projects have different requirements on component capacity, and the cost control is different. Sometimes, the shielding rate is large, the component loss is large, the component cost is high, but the component capacity is also large; sometimes the shielding ratio is small, the component loss is small, the component cost is low, but the component capacity is also small. Therefore, a line graph between component capacity profits and component costs under different target photovoltaic component arrangement schemes can be drawn, so that an optimal scheme is selected.
In a specific implementation, the target profit may be determined according to the profit of the component capacity and the component cost, specifically, the profit a of the component capacity, which is obtained by subtracting the lost photovoltaic capacity of the component from the full capacity of the photovoltaic component, is multiplied by the annual factor y, the component cost is denoted as B, and the target profit is a×y-B. The y value is the application period of the photovoltaic panel which the user thinks, and can be customized. The value of the target profit can be calculated in sequence according to 0-100%, and the target photovoltaic module arrangement scheme corresponding to the maximum target profit is selected as the photovoltaic module arrangement scheme. The final photovoltaic module arrangement scheme can be determined by comprehensively considering the cost brought by the number of module blocks, the module light Fu Rong magnitude and the module loss photovoltaic capacity.
According to the embodiment, the photovoltaic module arrangement in the initial photovoltaic module arrangement scheme is optimized for the first time according to the initial shadow set, a photovoltaic module arrangement scheme after the first time optimization is obtained, then each variable shadow photovoltaic module in the photovoltaic module arrangement scheme after the first time optimization is determined according to the variable shadow set, the average shielding ratio corresponding to each variable shadow photovoltaic module is determined, the average shielding ratio is compared with a preset shielding ratio, if the average shielding ratio is larger than the preset shielding ratio, the variable shadow photovoltaic module is deleted, an optimized photovoltaic module arrangement scheme is obtained, if the average shielding ratio is smaller than or equal to the preset shielding ratio, the variable shadow photovoltaic module is reserved, an optimized photovoltaic module arrangement scheme is obtained, and then a target photovoltaic module arrangement scheme is determined according to the optimized photovoltaic module arrangement scheme. According to the embodiment, the average shielding ratio corresponding to the shadow photovoltaic modules is compared with the preset shielding ratio, the changed shadow photovoltaic modules are deleted or reserved according to the comparison result, and the optimized photovoltaic module arrangement scheme is obtained, so that the photovoltaic module arrangement is optimized, the target module arrangement scheme is further obtained according to the number of the optimized photovoltaic module arrangement schemes, and the final target module arrangement scheme can be obtained effectively.
