Description

Technical Field

[0001] The present invention relates to the technical field of solar power generation, and in particular to a photovoltaic component layout method. Background Art

[0002] By constructing a three-dimensional model, the layout of photovoltaic modules in different sites (such as roofs, ground, etc.) can be intuitively seen. In complex terrain or building structure environments, the available space of the site can be accurately evaluated. The three-dimensional model can combine local meteorological data (such as the annual changes in the solar altitude angle and azimuth angle) and geographic information (such as terrain and the shading of surrounding buildings) to conduct detailed light analysis, and can simulate the amount of solar radiation received by photovoltaic modules in different seasons and different time periods. In this way, the power generation of photovoltaic power generation systems can be more accurately predicted, providing reliable data support for the economic benefit evaluation of the project. The existing technology determines the appropriate photovoltaic modules and the layout parameters of photovoltaic modules according to the maximum outdoor light intensity acceptable to different types of buildings at different times and the reflected light intensity that affects the buildings, effectively avoiding the impact of light pollution on surrounding buildings. However, different photovoltaic modules have different reflection conditions on surrounding buildings. The reflection condition is not analyzed according to the reflection properties of the photovoltaic modules, resulting in insufficient control of the reflection condition of the photovoltaic modules, which is easy to cause misjudgment.

[0003] Chinese patent application number: CN202311872810.1 discloses a method, device, equipment and medium for determining a photovoltaic module layout scheme, including selecting photovoltaic modules with low reflected light intensity and meeting the capacity maximization layout; simulating the maximum power angle of photovoltaic modules under capacity maximization layout under illumination intensity under different meteorological conditions; determining the reflected light intensity that will affect the building at different times based on the maximum power angle; determining photovoltaic modules and target photovoltaic modules that have no impact on the building and the photovoltaic module angle corresponding to the target photovoltaic module at the time when the illumination intensity exceeds the standard according to the maximum outdoor illumination intensity acceptable to the building of different categories and the reflected light intensity that will affect the building; adjusting the photovoltaic module angle as the basic angle of the target photovoltaic module, and determining the photovoltaic module layout scheme in combination with the layout of the photovoltaic modules that have no impact on the building. This method effectively avoids the impact of light pollution on surrounding buildings.

[0004] However, the prior art still has the following problems: Failure to analyze the reflection situation based on the reflection properties of the photovoltaic modules results in insufficient control of the reflection situation of the photovoltaic modules, which can easily lead to misjudgment. Summary of the invention

[0005] To this end, the present invention provides a photovoltaic module layout method to overcome the problem in the prior art that the reflection condition is not analyzed according to the reflection properties of the photovoltaic module, resulting in insufficient difficulty in controlling the reflection condition of the photovoltaic module and easily leading to misjudgment.

[0006] To achieve the above-mentioned purpose, the present invention provides a photovoltaic module layout method. It includes: Step S1, generating a three-dimensional model based on the environment where the photovoltaic components are to be deployed, setting photovoltaic panels at corresponding positions of the three-dimensional model according to the construction plan, obtaining historical illumination data of the environment to be deployed, and constructing an illumination simulation environment in the three-dimensional model based on the historical illumination data; Step S2, determining the buildings adjacent to the photovoltaic module, screening the reflection area receiving the reflected light of the photovoltaic module, periodically acquiring the area of ​​the reflection area, and obtaining the reflection area; Step S3, obtaining the reflection area of ​​the reflected light received from the photovoltaic module in a single cycle, preliminarily determining whether the layout of the photovoltaic module is qualified based on the reflection area, and further analyzing when the layout is preliminarily determined to be unqualified, including: Based on the time domain discreteness of the reflection area of ​​each sub-period, it is analyzed whether the layout of photovoltaic modules is affected by the illumination angle. When it is determined that the layout is affected by the illumination angle, the reasons for the unqualified layout are analyzed according to the distribution of the sub-periods. Or analyze the reasons for unqualified layout based on the number of PV modules; Step S4, issuing corresponding processing instructions based on the analyzed reasons for the unqualified layout, re-laying out the photovoltaic panels according to the processing instructions, and constructing a three-dimensional model to re-analyze whether the layout of the photovoltaic components is qualified.

[0007] Furthermore, the preliminary determination of whether the layout of the photovoltaic modules is qualified based on the reflection area includes: Determine the total area of ​​the reflective region that receives reflected light from the PV module in a single cycle, If the total area is less than or equal to the first preset total area standard threshold, the photovoltaic assembly is determined to be arranged in a qualified manner; If the total area is greater than the first preset total area standard threshold and less than or equal to the second preset total area standard threshold, it is preliminarily determined that the layout of the photovoltaic module is unqualified, and whether the layout of the photovoltaic module is affected by the illumination angle is analyzed based on the time domain discreteness of the reflection area of ​​each sub-period; If the total area is greater than the second preset total area standard threshold, it is determined that the layout of the photovoltaic components is unqualified, and the reasons for the unqualified layout are analyzed according to the number of photovoltaic components.

[0008] Furthermore, the analysis of whether the layout of photovoltaic modules is affected by the illumination angle based on the time domain discreteness of the reflection area of ​​each sub-period includes: Divide a single cycle into several sub-cycles, The area of ​​the reflection region receiving the reflected light of the photovoltaic module in each sub-period is determined respectively to obtain the sub-region reflection area. Calculate the variance of each sub-region area to obtain the time domain discreteness, If the time domain dispersion is greater than or equal to the preset time domain dispersion standard threshold, it is determined that the layout of the photovoltaic module is affected by the illumination angle; If the time domain discreteness is less than the preset time domain discreteness standard threshold, it is determined that the layout of the photovoltaic components is not affected by the illumination angle, and the reasons for the unqualified layout are analyzed according to the number of photovoltaic components.

[0009] Further, under the condition that the reason for the unqualified layout is that the reflection of the photovoltaic module is affected by the illumination angle, the sub-periods in which the reflection area of ​​the sub-region is higher than the preset value are screened, and the strong reflection sub-periods are determined. The reasons for the unqualified layout are analyzed based on the distribution of the strong reflection sub-periods, including: If the strong reflection sub-period distribution is discrete, determining the reason for the unqualified layout according to the number of photovoltaic modules; If the strong reflection sub-periods are concentrated, it is determined that the reason for the unqualified layout is that the amount of sample data used for lighting simulation is insufficient, and the sample data is increased.

[0010] Furthermore, under the condition of determining whether to increase sample data, the ratio of the strong reflection sub-period to the total number of self-periods is calculated to obtain the proportion of strong reflection sub-periods, and sample data for lighting simulation is obtained based on big data. The sample data is increased according to the proportion of strong reflection sub-periods, wherein the increase in sample data is positively correlated with the proportion of strong reflection sub-periods.

[0011] Further, under the condition that the reason for the unqualified layout is analyzed based on the number of photovoltaic modules, the photovoltaic modules with reflection are determined and marked based on the reflection area, the marked photovoltaic modules are recorded as reflection modules, the number of reflection modules is counted, and the ratio of the number of reflection modules to the total number of photovoltaic modules is calculated. The reason for the unqualified layout is analyzed based on the ratio, including: If the ratio is less than or equal to a first preset ratio standard threshold, it is determined that the reason for the unqualified arrangement is that the installation of the reflective component is unqualified, and the installation angle of the reflective component is adjusted; If the ratio is greater than the first preset ratio standard threshold and less than or equal to the second preset ratio standard threshold, a secondary determination is made on the cause of the unqualified deployment based on the distribution of the reflective components; If the ratio is greater than the second preset ratio standard threshold, it is determined that the reason for the unqualified layout is that there is a problem with the layout of the photovoltaic components, and the layout area is re-determined.

[0012] Furthermore, the second determination of the reasons for the unqualified deployment based on the distribution of the reflective components includes: If the reflective components are dispersed, it is determined that the reason for the unqualified arrangement is that the installation of the reflective components is unqualified, and the installation angle of the reflective components is adjusted; If the reflective components are concentratedly distributed, it is determined that the reason for the unqualified layout is that there is a problem with the layout of the photovoltaic components, and the layout area is re-determined.

[0013] Further, under the condition that the installation angle of the reflective assembly is adjusted, the photovoltaic assembly is re-arranged to construct a three-dimensional model according to the adjusted parameters, the power generation of the re-constructed three-dimensional model is recorded, and whether the photovoltaic assembly is supplemented is analyzed based on the power generation, including: If the power generation is lower than the preset power generation standard threshold, it is determined that the photovoltaic components need to be supplemented; If the power generation is higher than the preset power generation standard threshold, it is determined not to supplement the photovoltaic components.

[0014] Compared with the prior art, the beneficial effect of the present invention lies in that a three-dimensional model is constructed according to the environment in which the photovoltaic components are to be deployed and the specific parameters of the photovoltaic components. Considering that the excessive reflection ability of the photovoltaic components will cause light pollution and affect the space use of surrounding buildings, the present invention preliminarily determines whether the deployment of the photovoltaic components is qualified based on the reflection area of ​​the photovoltaic components on the surrounding buildings within a single detection cycle, and when it is preliminarily determined that the deployment is unqualified, the detection cycle is divided into several sub-cycles, and further determination is made based on the fluctuation of the reflection area within each sub-cycle, or the reason for the unqualified deployment is analyzed based on the number of photovoltaic components set, thereby improving the control accuracy of the deployment of the photovoltaic components, and adjusting the corresponding parameters according to the analysis results, thereby improving the rationality of the deployment of the photovoltaic panels and reducing light pollution.

[0015] Furthermore, the present invention takes into account that the illumination angle of the light source to the photovoltaic module will change with the change of time, and the change of the illumination angle will affect the reflection of the photovoltaic module to the surrounding buildings. The present invention divides a single detection cycle into several sub-cycles, and analyzes the influence of the illumination angle on the photovoltaic module according to the fluctuation of the reflection area of ​​the photovoltaic module to the surrounding buildings in each sub-cycle, thereby further improving the control precision of the photovoltaic module layout and improving the analysis accuracy.

[0016] Furthermore, in the present invention, when the fluctuation degree of the reflection area of ​​the photovoltaic components on the surrounding buildings is relatively large within each sub-period, it is determined that the reflection degree of the photovoltaic components on the buildings is greatly affected by the change of the light source, and it is determined that there are time periods with high reflection intensity of individual photovoltaic components, and the time periods with high reflection intensity are marked to facilitate the subsequent adjustment of the parameters of the photovoltaic components in this time period, thereby reducing light pollution.

[0017] Furthermore, the present invention takes into account that the more photovoltaic modules there are, the easier it is to generate reflection. Therefore, the reflected photovoltaic modules are determined according to the emission conditions of the photovoltaic modules, and the proportion of the reflected photovoltaic modules is determined according to the ratio of the number of reflected photovoltaic modules to the total number of photovoltaic modules. The reasons for the unqualified layout of the photovoltaic modules are analyzed according to the proportion. When the proportion is small, it is determined that the installation of the photovoltaic modules is unqualified, and the installation angle of the photovoltaic modules is adjusted to reduce light pollution.

[0025] The photovoltaic assembly layout method provided in this embodiment includes: Step S1, generating a three-dimensional model based on the environment where the photovoltaic components are to be deployed, setting photovoltaic panels at corresponding positions of the three-dimensional model according to the construction plan, obtaining historical illumination data of the environment to be deployed, and constructing an illumination simulation environment in the three-dimensional model based on the historical illumination data; Step S2, determining the buildings adjacent to the photovoltaic module, screening the reflection area receiving the reflected light of the photovoltaic module, periodically acquiring the area of ​​the reflection area, and obtaining the reflection area; Step S3, obtaining the reflection area of ​​the reflected light received from the photovoltaic module in a single cycle, preliminarily determining whether the layout of the photovoltaic module is qualified based on the reflection area, and further analyzing when the layout is preliminarily determined to be unqualified, including: Based on the time domain discreteness of the reflection area of ​​each sub-period, it is analyzed whether the layout of photovoltaic modules is affected by the illumination angle. When it is determined that the layout is affected by the illumination angle, the reasons for the unqualified layout are analyzed according to the distribution of the sub-periods.

[0026] In the present invention, a three-dimensional model is constructed according to the environment in which the photovoltaic components are to be deployed and the specific parameters of the photovoltaic components. Considering that the excessive reflective ability of the photovoltaic components will cause light pollution and affect the space use of surrounding buildings, the present invention preliminarily determines whether the deployment of the photovoltaic components is qualified based on the reflection area of ​​the photovoltaic components on the surrounding buildings within a single detection cycle, and when the deployment is preliminarily determined to be unqualified, the detection cycle is divided into several sub-cycles, and further determination is made based on the fluctuation of the reflection area within each sub-cycle, or the reason for the unqualified deployment is analyzed based on the number of photovoltaic components set, thereby improving the control accuracy of the deployment of the photovoltaic components, and adjusting the corresponding parameters according to the analysis results, thereby improving the rationality of the deployment of the photovoltaic panels and reducing light pollution.

[0027] See also Figure 2 As shown, it is a flow chart for preliminarily determining whether the layout of photovoltaic modules is qualified.

[0028] Specifically, the preliminary determination of whether the layout of the photovoltaic modules is qualified based on the reflection area includes: Determine the total area of ​​the reflective region that receives reflected light from the PV module in a single cycle, If the total area is less than or equal to the first preset total area standard threshold, the photovoltaic assembly is determined to be arranged in a qualified manner; If the total area is greater than the first preset total area standard threshold and less than or equal to the second preset total area standard threshold, it is preliminarily determined that the layout of the photovoltaic module is unqualified, and whether the layout of the photovoltaic module is affected by the illumination angle is analyzed based on the time domain discreteness of the reflection area of ​​each sub-period; If the total area is greater than the second preset total area standard threshold, it is determined that the layout of the photovoltaic components is unqualified, and the reasons for the unqualified layout are analyzed according to the number of photovoltaic components.

[0029] Specifically, in this embodiment, the first preset total area standard threshold and the second preset total area standard threshold are obtained in advance, and the reflection area standard at which the photovoltaic components reflect the surrounding buildings but do not affect the normal operation of the surrounding buildings is determined based on big data. The first preset total area standard threshold is 1.05 times the reflection area standard, and the second preset total area standard threshold is 1.2 times the reflection area standard.

[0030] The present invention takes into account that the illumination angle of the light source to the photovoltaic module will change with the change of time, and the change of the illumination angle will affect the reflection of the photovoltaic module to the surrounding buildings.

The sample data is increased according to the proportion of strong reflection sub-periods, wherein the increase in sample data is positively correlated with the proportion of strong reflection sub-periods.

[0038] Specifically, under the condition that the reasons for the unqualified layout are analyzed based on the number of photovoltaic modules, the photovoltaic modules with reflection are determined and marked based on the reflection area, the marked photovoltaic modules are recorded as reflection modules, the number of reflection modules is counted, and the ratio of the number of reflection modules to the total number of photovoltaic modules is calculated. The reasons for the unqualified layout are analyzed based on the ratio, including: If the ratio is less than or equal to a first preset ratio standard threshold, it is determined that the reason for the unqualified arrangement is that the installation of the reflective component is unqualified, and the installation angle of the reflective component is adjusted; If the ratio is greater than the first preset ratio standard threshold and less than or equal to the second preset ratio standard threshold, a secondary determination is made on the cause of the unqualified deployment based on the distribution of the reflective components; If the ratio is greater than the second preset ratio standard threshold, it is determined that the reason for the unqualified layout is that there is a problem with the layout of the photovoltaic components, and the layout area is re-determined.

[0039] Specifically, in this embodiment, the first preset ratio standard threshold is selected in the interval [0.5, 0.6], and the second preset ratio standard threshold is selected in the interval [0.75, 0.85].
