Example 1
Fig. 1 is a flow chart of a method for determining a layout scheme of a photovoltaic module according to an embodiment of the present invention, where the method may be applicable to a case of laying a photovoltaic module near a building, and the method may be performed by a device for determining a layout scheme of a photovoltaic module, where the device may be implemented by software and/or hardware and is generally integrated on an electronic device, and in this embodiment, the electronic device includes but is not limited to: a computer device.
As shown in fig. 1, a method for determining a layout scheme of a photovoltaic module according to an embodiment of the present invention includes the following steps:
s110, after determining that buildings influenced by light reflection exist around the area where the photovoltaic modules are paved, marking the buildings as influencing the buildings, and selecting the photovoltaic modules which have low reflected light intensity and meet the capacity maximization layout.
The building which is affected by the light reflection of the photovoltaic module can be determined in various modes around the area where the photovoltaic module is paved, and optionally, which buildings are affected by the light reflection can be determined through experimental data, and the building which is affected by the light reflection around the photovoltaic module can be analyzed through modeling.
In this embodiment, the number of buildings affected by light reflection is at least one, and after the buildings affected by light reflection are identified, the buildings can be marked as affecting buildings, and the affecting buildings can be understood as buildings affected by light reflected by the photovoltaic module. After determining that the influence on the building exists around, the photovoltaic modules with low reflected light intensity can be selected for layout, the photovoltaic capacities achieved by different photovoltaic modules after layout are different, and the photovoltaic modules with low reflected light intensity, which meet the requirement of capacity maximization layout, need to be selected so as to reduce the light reflection of the photovoltaic modules on the influence on the building to the greatest extent.
The photovoltaic module with low reflected light intensity can absorb more light rays and reduce reflection. The selection mode of the photovoltaic module with low reflected light intensity can be as follows: and selecting a photovoltaic module with an anti-reflection coating coated on the surface, selecting a photovoltaic module with a black backboard, and selecting a photovoltaic module with a semiconductor material with small radiation loss.
S120, simulating the maximum power angle of the photovoltaic module under the capacity maximization arrangement under the illumination intensity of different meteorological conditions.
The illumination intensities under different meteorological conditions are different, the annual illumination intensity can be obtained from meteorological data of one year, and the optimal reflection angle corresponding to the maximum capacity of the photovoltaic module under different types of illumination intensities is simulated.
Specifically, simulating the maximum power angle of the photovoltaic module under the capacity maximization arrangement under the illumination intensity of different meteorological conditions comprises: acquiring meteorological data of one year, and simulating the illumination intensity of the whole year through the meteorological data; and classifying the annual illumination intensity, and taking the reflection angle corresponding to the maximum capacity of the photovoltaic module under different types of illumination intensity as the maximum power angle.
The same level of illumination intensity may be classified into one category, for example, the illumination intensity may be classified into three categories of strong, medium and weak, and the annual illumination intensity may be classified into these three categories.
S130, determining the reflected light intensity which affects the building at different times based on the maximum power angle.
The reflected light intensity that affects the building is understood to be the reflected light intensity of the photovoltaic module.
In this embodiment, after obtaining the maximum power angle, the reflected light intensity and the reflected angle of the photovoltaic panel at different times under the angle may be determined, and the reflected light intensity is used as the initial reflected light intensity; then determining a light transmission area affecting the light radiation area on the building in the reflection angle range; finally, the reflected light intensity which influences the building to be subjected to different times can be calculated according to the light transmission area and the initial emitted light intensity through an illumination intensity attenuation formula.
And S140, determining the photovoltaic modules and the target photovoltaic modules which have no influence on the building and the photovoltaic module angles corresponding to the target photovoltaic modules at the moment when the influence of the illumination intensity exceeds the standard according to the outdoor highest illumination intensity of different types of influence buildings acceptable at different times and the reflected light intensity of the influence buildings.
The target photovoltaic module may be a photovoltaic module that causes the reflected light intensity that affects the building to be higher than the acceptable light intensity that affects the building. A photovoltaic module that causes the intensity of reflected light that affects a building to be less than or equal to the intensity of illumination that affects acceptable lighting for the building is used as a photovoltaic module that does not affect the building. The time when the influence of the illumination intensity exceeds the standard can be understood as the time when the influence of the illumination intensity on the building is higher than the time when the influence of the illumination intensity on the building is acceptable, and the time when the influence of the illumination intensity exceeds the standard can comprise a plurality of times.
In this embodiment, the reflected light intensity which can affect the building is compared with the outdoor highest illumination intensity acceptable by different types of affecting the building in different time, the target photovoltaic module and the illumination intensity affecting exceeding time can be determined according to the comparison result, and the photovoltaic module angle of the target photovoltaic module at the illumination intensity affecting exceeding time is recorded.
It should be noted that the influencing buildings may be classified into a plurality of categories according to the characteristics of the influencing buildings, and may include commercial buildings, office buildings, and residential buildings, and the highest illumination intensity acceptable for different types of buildings at different times may also be different. For example, commercial buildings include business hours and non-business hours, i.e., there is a correspondence to the highest illumination intensity acceptable to commercial buildings during business hours and the highest illumination intensity acceptable to commercial buildings during non-business hours; for example, an office building includes an on-time and an off-time, i.e., corresponds to a highest illumination intensity acceptable to the office building during the on-time and a highest illumination intensity acceptable to the office building during the off-time; for example, a residential building includes a normal activity time and a rest time, i.e., corresponds to a highest illumination intensity acceptable to the residential building during the normal activity time and a highest illumination intensity acceptable to the residential building during the rest time.
And S150, taking the angle of the photovoltaic module as a basic adjustment angle of the target photovoltaic module to perform angle adjustment, and determining a photovoltaic module layout scheme by combining the layout of the photovoltaic modules which have no influence on the building.
The photovoltaic module layout scheme comprises layout of photovoltaic modules and angles of the photovoltaic modules.
In this embodiment, the angle of the photovoltaic module may be first used as a basic adjustment angle of the target photovoltaic module to perform angle adjustment to determine a set of routable photovoltaic modules, and then the angle of the routable photovoltaic modules may be adjusted back to obtain an optimal angle; and determining whether the photovoltaic modules are distributed according to the scheme according to the photovoltaic capacity value of the routable photovoltaic module at the optimal angle.
In this embodiment, the layout scheme of the photovoltaic module further includes layout of the photovoltaic module that has no influence on the building, and specifically includes layout angles of the photovoltaic module that has no influence on the building.
It should be noted that, if the capacity satisfies the condition, the photovoltaic module may be arranged, and if the capacity does not satisfy the condition, the photovoltaic module is not arranged.
According to the method for determining the layout scheme of the photovoltaic modules, firstly, after a building influenced by light reflection exists around a laid photovoltaic module area, the building is marked as an influencing building, and the photovoltaic modules with low reflected light intensity and capacity maximization layout meeting requirements are selected; secondly, simulating the maximum power angle of the photovoltaic module under the capacity maximization arrangement under the illumination intensity of different meteorological conditions; then determining the reflected light intensity which affects the building and can be received at different times based on the maximum power angle; then according to the outdoor highest illumination intensity acceptable by different types of influencing buildings at different times and the reflected light intensity which can be received by the influencing buildings, determining the photovoltaic modules and target photovoltaic modules which have no influence on the buildings and the photovoltaic module angles corresponding to the target photovoltaic modules at the moment when the illumination intensity influences exceed the standard; and finally, taking the angle of the photovoltaic module as a basic adjustment angle of the target photovoltaic module to perform angle adjustment, and determining a photovoltaic module layout scheme by combining the layout of the photovoltaic modules which have no influence on the building. According to the method, the target photovoltaic module and the basic angle are determined by comparing the outdoor highest illumination intensity acceptable in different time and the reflected light intensity received by the affected building, the optimal angle for arranging the target photovoltaic module can be obtained by carrying out angle adjustment on the photovoltaic module according to the basic angle, and the influence of light reflection on surrounding buildings can be effectively avoided by arranging the photovoltaic module by the method.
On the basis of the above embodiments, modified embodiments of the above embodiments are proposed, and it is to be noted here that only the differences from the above embodiments are described in the modified embodiments for the sake of brevity of description.
In one embodiment, determining that there is an influencing building affected by light reflection around an area where the photovoltaic module is laid comprises: determining a pre-influence building with light reflection influence probability around the paved photovoltaic module area through the constructed environment model, and constructing a pre-influence building set;
and removing the buildings with the building heights larger than the preset height and the buildings without the requirement on the illumination intensity from the pre-influence building set to obtain the influence building set.
The construction process of the environment model comprises the step of outwards drawing circles with preset sizes by taking four vertexes of a roof paved with the photovoltaic module as circle centers respectively to construct the environment model. As shown in fig. 2, fig. 2 is a schematic diagram of an environmental model in a method for determining a layout scheme of a photovoltaic module according to an embodiment of the present invention, where circles with a radius of 300 meters are drawn outwards by using four vertices of a roof on which the photovoltaic module is laid as circle centers, and in actual operation, circles with a radius of 300 meters are drawn on a contour line at intervals of 0.1 meter outside the four vertices.
Wherein, the buildings possibly influenced by light reflection around the area where the photovoltaic modules are laid can be taken as pre-influence buildings, and the set of at least one pre-influence building combination is taken as a pre-influence building set.
In this embodiment, after the pre-influence building set is obtained, the pre-influence buildings that do not meet the conditions in the pre-influence building set may be removed, and the remaining identification buildings in the pre-influence building set may be used as influence buildings. Wherein unconditional buildings can be removed from the pre-affected building set according to building height and building type. Optionally, the pre-affected building with the height of the corresponding building being larger than the preset height can be removed, the pre-affected building with the type of the building being not required for the illumination intensity can be removed, and the pre-affected building with the no requirement for the illumination intensity can be a storage type building. Preferably, the preset height may be a height of a roof on which the photovoltaic module is laid.
Further, determining, by the constructed environmental model, that a pre-affected building having a probability of being affected by light reflection exists around the paved photovoltaic module area, includes: and taking a union region of all circles in the environment model, and marking the buildings in the union region and the buildings intersected with the union region as pre-affected buildings with light reflection influence probability around the paved photovoltaic module region.
Illustratively, as shown in fig. 2, the building 1 and the building 2 in fig. 2 are the buildings in the union region, the building 3 is the building having the intersection with the union region, and the building 1, the building 2, and the building 3 are combined as the pre-affected buildings to form the pre-affected building set.
Further, the method further comprises: simulating the capacity of the photovoltaic module which is laid for a preset time length according to the layout scheme of the photovoltaic module; evaluating whether the simulation result meets the standard; if yes, arranging the photovoltaic modules according to the photovoltaic module arrangement scheme; if not, the photovoltaic module is not paved.
The preset time period may be set according to actual requirements, and is not particularly limited herein.
In this embodiment, whether to perform layout according to the determined layout scheme of the photovoltaic module may be determined by evaluating the simulation result. The simulation result can be used for distributing the capacity of the photovoltaic module which is reached for a certain time according to the determined distribution scheme. There are various ways of evaluating whether the simulation result meets the standard, and this is not an example. Further, after the target photovoltaic module is erected according to the optimal angle, traversing the moment with highest fitting degree of the current meteorological data and the meteorological data of one year in history, taking the rotation angle of the target module under the meteorological data with the highest fitting degree as the operation angle of the target photovoltaic panel, and ensuring that the photovoltaic module does not influence the life of nearby people according to a plan in actual work.

In addition, the light transmittance of the light radiation area can be identified, for example, the light transmittance of common glass and the light transmittance of special glass are different, and identification is needed.
S240, obtaining initial reflected light intensity and reflection angle of the photovoltaic module at different times when the angle of the photovoltaic module is the maximum power angle after simulation.

And S260, calculating the reflected light intensity which affects the building at different times according to an attenuation formula of the illumination intensity based on the initial reflected light intensity of the light transmission area and the photovoltaic module at different times.
Specifically, based on the light transmission area and the initial reflected light intensity of the photovoltaic module, the reflected light intensity which affects the building is calculated according to an attenuation formula of the illumination intensity, and the method comprises the following steps: calculating a distance value between a center point of one photovoltaic module and a center point of the building surface with a light transmission area for each photovoltaic module; calculating the ratio of the initial reflected light intensity of the photovoltaic module at one time to the square of the distance value to obtain the reflected light intensity affecting the roof of the building at the same time; calculating the product of the reflected light intensity on the roof of the building and the shielding coefficient of the light transmission area on the building to obtain the final reflected light intensity of the photovoltaic module in the same time; taking the sum of the final reflected light intensities of each photovoltaic module in one time as the reflected light intensity which affects the building in the same time; the sum of the reflected light intensities that each influencing building will be subjected to during a time is taken as the reflected light intensity that each influencing building will be subjected to during a time.
Wherein, every photovoltaic module can all calculate the reflected light intensity on influencing the building roofing according to illumination intensity decay formula, and illumination intensity decay formula is as follows:

After the calculation of the I, the shielding coefficient of the light transmission area can be multiplied by the I to obtain the final reflected light intensity of the photovoltaic module in a certain time. According to the method, the final reflected light intensity of each photovoltaic module at different times can be obtained through calculation, the sum of the final reflected light intensities of each photovoltaic module at the same time is used as the reflected light intensity which can influence the building at the same time, the reflected light intensity which can influence the building at different times can be obtained, and the sum of the reflected light intensities which can influence the building at the same time is used as the reflected light intensity which can influence the building at the same time.
