Description

Technical Field

[0001] This invention relates to the field of solar power generation technology, and in particular to a method for deploying photovoltaic modules. Background Technology

[0002] By constructing 3D models, the layout of photovoltaic (PV) modules in different sites (such as rooftops and ground surfaces) can be visualized intuitively. In complex terrain or building structures, the available space of a site can be accurately assessed. 3D models can combine local meteorological data (such as the annual variations in solar altitude and azimuth angles) and geographical information (such as terrain and the shading effect of surrounding buildings) to conduct detailed illumination analysis, simulating the amount of solar radiation received by PV modules at different times of the year. This approach allows for more accurate prediction of the power generation of PV systems, providing reliable data support for project economic benefit assessment. Existing technologies determine suitable PV modules and their deployment parameters based on the maximum acceptable outdoor light intensity for different types of buildings at different times and the reflected light intensity received by those buildings, effectively avoiding the impact of light pollution on surrounding buildings. However, different PV modules reflect light differently from surrounding buildings. Without analyzing the reflection characteristics of PV modules, the control over their reflection is insufficient and prone to misjudgment.

[0003] Chinese Patent Application No. CN202311872810.1 discloses a method, apparatus, equipment, and medium for determining a photovoltaic (PV) module deployment scheme. The method includes selecting PV modules with low reflected light intensity that maximize capacity; simulating the maximum power angle of the PV modules under different meteorological conditions and light intensity at maximum capacity; determining the reflected light intensity affecting buildings at different times based on the maximum power angle; determining PV modules that do not affect buildings, target PV modules, and the PV module angle corresponding to the moment when the light intensity exceeds the limit, based on the highest acceptable outdoor light intensity for different types of buildings at different times and the reflected light intensity affecting buildings; adjusting the PV module angle as the base angle of the target PV module; and determining the PV module deployment scheme by combining the deployment of the PV modules that do not affect buildings. This method effectively avoids the impact of light pollution on surrounding buildings.

[0004] However, existing technologies still have the following problems:

[0005] The failure to analyze the reflection characteristics of photovoltaic modules makes it difficult to control the reflection of photovoltaic modules and easily leads to misjudgment. Summary of the Invention

[0006] To address this issue, the present invention provides a photovoltaic module deployment method to overcome the problem in the prior art that the reflection situation is not analyzed based on the reflection properties of the photovoltaic module, resulting in insufficient control over the reflection situation of the photovoltaic module and easy misjudgment.

[0007] To achieve the above objectives, the present invention provides a method for deploying photovoltaic modules. This method includes:

[0008] Step S1: Generate a three-dimensional model based on the environment where the photovoltaic modules are to be deployed; set up photovoltaic panels at the corresponding positions in the three-dimensional model according to the construction plan; obtain historical illumination data of the environment to be deployed; and construct a illumination simulation environment in the three-dimensional model based on the historical illumination data.

[0009] Step S2: Determine the buildings adjacent to the photovoltaic modules, screen the reflection areas that receive the reflected light from the photovoltaic modules, periodically obtain the area of ​​the reflection areas, and obtain the reflection area.

[0010] Step S3: Obtain the reflection area of ​​the reflected light received from the photovoltaic module within a single cycle. Based on the reflection area, preliminarily determine whether the photovoltaic module layout is qualified. If the layout is preliminarily determined to be unqualified, further analysis is performed, including:

[0011] This analysis uses the time-domain dispersion of the reflective area of ​​each sub-cycle to determine whether the layout of photovoltaic modules is affected by the illumination angle. Furthermore, when determining if the layout is affected by the illumination angle, the analysis considers the distribution of the sub-cycles to determine the reasons for any layout defects.

[0012] Alternatively, the reasons for substandard installation can be analyzed based on the number of photovoltaic modules.

[0013] Step S4: Based on the analyzed reasons for the unqualified layout, issue corresponding processing instructions, re-lay out the photovoltaic panels according to the processing instructions, construct a three-dimensional model, and re-analyze whether the photovoltaic module layout is qualified.

[0014] Furthermore, the preliminary determination of whether the photovoltaic module layout is qualified based on the reflection area includes:

[0015] Determine the total area of ​​the reflection region that receives reflected light from the photovoltaic module within a single cycle.

[0016] If the total area is less than or equal to the first preset total area standard threshold, the photovoltaic module installation is deemed qualified.

[0017] 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 photovoltaic module layout is unqualified, and the layout of the photovoltaic module is analyzed based on the time-domain dispersion of the reflection area of ​​each sub-cycle to determine whether it is affected by the illumination angle.

[0018] If the total area is greater than the second preset total area standard threshold, the photovoltaic module layout is determined to be unqualified, and the reason for the unqualified layout is analyzed based on the number of photovoltaic modules.

[0019] Furthermore, the time-domain discreteness analysis based on the reflective area of ​​each sub-cycle to determine whether the deployment of photovoltaic modules is affected by the illumination angle includes:

[0020] Divide a single period into several sub-periods.

[0021] The area of ​​the reflection region receiving reflected light from the photovoltaic module in each sub-cycle is determined to obtain the reflection area of ​​the sub-region.

[0022] Calculate the variance of the area of ​​each sub-region to obtain the time-domain dispersion.

[0023] 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.

[0024] If the time-domain dispersion is less than the preset time-domain dispersion standard threshold, it is determined that the deployment of photovoltaic modules is not affected by the illumination angle, and the reasons for the unqualified deployment are analyzed based on the number of photovoltaic modules.

[0025] Furthermore, if the reason for the unqualified deployment is determined to be the influence of the illumination angle on the reflection of the photovoltaic modules, sub-periods with a reflection area higher than a preset value are selected to determine strong reflection sub-periods. Based on the distribution of strong reflection sub-periods, the reasons for the unqualified deployment are analyzed, including:

[0026] If the strong reflective sub-period distribution is discrete, the reason for the unqualified layout is determined based on the number of photovoltaic modules.

[0027] If the strong reflective sub-periods are concentrated, the reason for the unqualified layout is that the amount of sample data used for illumination simulation is insufficient, and more sample data should be added.

[0028] Furthermore, under the condition of increasing sample data, the ratio of strong reflection sub-periods to the total number of self-periods is calculated to obtain the proportion of strong reflection sub-periods. Sample data for illumination simulation is obtained based on big data, and the sample data is increased according to the proportion of strong reflection sub-periods. The increase in sample data is positively correlated with the proportion of strong reflection sub-periods.

[0029] Furthermore, after determining the reasons for non-compliance in the installation based on the number of photovoltaic modules, the photovoltaic modules exhibiting reflection are identified and marked based on the reflection area. These marked photovoltaic modules are designated as reflecting modules. The number of reflecting modules is counted, and the ratio of the number of reflecting modules to the total number of photovoltaic modules is calculated. Based on this ratio, the reasons for non-compliance in the installation are analyzed, including:

[0030] If the ratio is less than or equal to the first preset ratio standard threshold, the reason for the unqualified layout is that the installation of the reflective component is unqualified, and the installation angle of the reflective component is adjusted.

[0031] If the ratio is greater than the first preset ratio standard threshold and less than or equal to the second preset ratio standard threshold, then a secondary determination is made based on the distribution of the reflective components to determine the reason for the unqualified deployment.

[0032] If the ratio is greater than the second preset ratio standard threshold, the reason for the unqualified deployment is determined to be a problem with the deployment of photovoltaic modules, and the deployment area is redefined.

[0033] Furthermore, the secondary determination of the reasons for unqualified deployment based on the distribution of the reflective components includes:

[0034] If the reflective components are scattered, the reason for the unqualified layout is that the reflective components are not installed properly, and the installation angle of the reflective components is adjusted.

[0035] If the reflective components are concentrated in one area, the reason for the unqualified layout is determined to be a problem with the layout of the photovoltaic components, and the layout area should be redefined.

[0036] Furthermore, after adjusting the installation angle of the reflective components, a three-dimensional model of the photovoltaic modules is reconstructed according to the adjusted parameters. The power generation of the reconstructed three-dimensional model is recorded, and an analysis is conducted based on the power generation to determine whether to supplement the photovoltaic modules, including:

[0037] If the power generation is lower than the preset power generation standard threshold, it is determined that additional photovoltaic modules are needed;

[0038] If the power generation exceeds the preset power generation standard threshold, it is determined that no additional photovoltaic modules will be added.

[0039] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention constructs a three-dimensional model based on the environment where the photovoltaic modules are to be deployed and the specific parameters of the photovoltaic modules. Considering that excessive reflectivity of photovoltaic modules can cause light pollution and affect the space utilization of surrounding buildings, the present invention preliminarily determines whether the deployment of photovoltaic modules is qualified based on the reflective area of ​​the photovoltaic modules on surrounding buildings in a single detection cycle. If the deployment is initially determined to be unqualified, the detection cycle is divided into several sub-cycles, and further determination is made based on the fluctuation of the reflective area in each sub-cycle, or the reasons for unqualified deployment are analyzed based on the number of photovoltaic modules installed. This improves the control accuracy of photovoltaic module deployment. Based on the analysis results, the corresponding parameters are adjusted, thereby improving the rationality of photovoltaic panel deployment and reducing light pollution.

[0040] Furthermore, this invention takes into account that the illumination angle of the light source on the photovoltaic module changes over time, and the change in the illumination angle affects the reflection of the photovoltaic module onto surrounding buildings. This invention divides a single detection cycle into several sub-cycles, and analyzes the degree of influence of the illumination angle on the photovoltaic module based on the fluctuation of the reflection area of ​​the photovoltaic module onto surrounding buildings in each sub-cycle, thereby further improving the control precision of the photovoltaic module deployment and improving the accuracy of the analysis.

[0041] Furthermore, in this invention, when the reflection area of ​​the photovoltaic module to the surrounding buildings fluctuates significantly within each sub-cycle, it is determined that the reflection degree of the photovoltaic module to the buildings is greatly affected by changes in the light source. It is determined that there are time periods when the reflection intensity of individual photovoltaic modules is high, and these time periods are marked to facilitate subsequent adjustment of the parameters of the photovoltaic modules during those time periods, thereby reducing light pollution.

[0042] Furthermore, this invention takes into account that the more photovoltaic modules there are, the easier it is to generate reflection. Therefore, the reflective photovoltaic modules are determined based on the emission of the photovoltaic modules, and the proportion of reflective photovoltaic modules is determined based on the ratio of the number of reflective photovoltaic modules to the total number of photovoltaic modules. The reasons for unqualified photovoltaic module layout are analyzed based on the proportion. When the proportion is low, the photovoltaic module is judged to be unqualified in installation, and the installation angle of the photovoltaic modules is adjusted to reduce light pollution.

[0052] Please see Figure 1 As shown, it is a flowchart of the photovoltaic module deployment method of the present invention.

[0053] The photovoltaic module deployment method provided in this embodiment includes:

[0054] Step S1: Generate a three-dimensional model based on the environment where the photovoltaic modules are to be deployed; set up photovoltaic panels at the corresponding positions in the three-dimensional model according to the construction plan; obtain historical illumination data of the environment to be deployed; and construct a illumination simulation environment in the three-dimensional model based on the historical illumination data.

[0055] Step S2: Determine the buildings adjacent to the photovoltaic modules, screen the reflection areas that receive the reflected light from the photovoltaic modules, periodically obtain the area of ​​the reflection areas, and obtain the reflection area.

[0056] Step S3: Obtain the reflection area of ​​the reflected light received from the photovoltaic module within a single cycle. Based on the reflection area, preliminarily determine whether the photovoltaic module layout is qualified. If the layout is preliminarily determined to be unqualified, further analysis is performed, including:

[0057] This analysis uses the time-domain dispersion of the reflective area of ​​each sub-cycle to determine whether the layout of photovoltaic modules is affected by the illumination angle. Furthermore, when determining if the layout is affected by the illumination angle, the analysis considers the distribution of the sub-cycles to determine the reasons for any layout defects.

[0058] Alternatively, the reasons for substandard installation can be analyzed based on the number of photovoltaic modules.

[0059] Step S4: Based on the analyzed reasons for the unqualified layout, issue corresponding processing instructions, re-lay out the photovoltaic panels according to the processing instructions, construct a three-dimensional model, and re-analyze whether the photovoltaic module layout is qualified.

[0060] In this invention, a three-dimensional model is constructed based on the environment where the photovoltaic modules are to be deployed and the specific parameters of the photovoltaic modules. Considering that excessive reflectivity of photovoltaic modules can cause light pollution and affect the space utilization of surrounding buildings, this invention preliminarily determines whether the deployment of photovoltaic modules is qualified based on the reflective area of ​​the photovoltaic modules on surrounding buildings within a single detection cycle. If the deployment is initially determined to be unqualified, the detection cycle is divided into several sub-cycles, and further determination is made based on the fluctuation of the reflective area within each sub-cycle, or the reasons for unqualified deployment are analyzed based on the number of photovoltaic modules installed. This improves the control accuracy of photovoltaic module deployment. Based on the analysis results, the corresponding parameters are adjusted, thereby improving the rationality of photovoltaic panel deployment and reducing light pollution.

[0061] Please see Figure 2 As shown, it is a flowchart for the preliminary determination of whether the photovoltaic module layout is qualified.

[0062] Specifically, the preliminary determination of whether the photovoltaic module layout is qualified based on the reflection area includes:

[0063] Determine the total area of ​​the reflection region that receives reflected light from the photovoltaic module within a single cycle.

[0064] If the total area is less than or equal to the first preset total area standard threshold, the photovoltaic module installation is deemed qualified.

[0065] 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 photovoltaic module layout is unqualified, and the layout of the photovoltaic module is analyzed based on the time-domain dispersion of the reflection area of ​​each sub-cycle to determine whether it is affected by the illumination angle.

[0066] If the total area is greater than the second preset total area standard threshold, the photovoltaic module layout is determined to be unqualified, and the reason for the unqualified layout is analyzed based on the number of photovoltaic modules.

[0067] Specifically, in this embodiment, the first preset total area standard threshold and the second preset total area standard threshold are pre-determined. Based on big data, the reflection area standard of the photovoltaic module that reflects the surrounding buildings but does not affect the normal operation of the surrounding buildings is determined. 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.

[0068] This invention takes into account that the illumination angle of the light source on the photovoltaic module changes over time, and the change in the illumination angle affects the reflection of the photovoltaic module onto surrounding buildings. This invention divides a single detection cycle into several sub-cycles, and analyzes the degree of influence of the illumination angle on the photovoltaic module based on the fluctuation of the reflection area of ​​the photovoltaic module onto surrounding buildings in each sub-cycle, thereby further improving the control precision of the photovoltaic module deployment and improving the accuracy of the analysis.

[0069] Please see Figure 3 As shown, it is a flowchart for determining whether the layout of photovoltaic modules is affected by the angle of sunlight.

[0070] Specifically, the analysis of whether the deployment of photovoltaic modules is affected by the illumination angle based on the time-domain discreteness of the reflective area of ​​each sub-cycle includes:

[0071] Divide a single period into several sub-periods.

[0072] The area of ​​the reflection region receiving reflected light from the photovoltaic module in each sub-cycle is determined to obtain the reflection area of ​​the sub-region.

[0073] Calculate the variance of the area of ​​each sub-region to obtain the time-domain dispersion.

[0074] 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.

[0075] If the time-domain dispersion is less than the preset time-domain dispersion standard threshold, it is determined that the deployment of photovoltaic modules is not affected by the illumination angle, and the reasons for the unqualified deployment are analyzed based on the number of photovoltaic modules.

[0076] Specifically, in this embodiment, the preset time-domain dispersion standard threshold is obtained by pre-determining. The reflection area of ​​the photovoltaic module to the surrounding buildings in each detection cycle under several qualified conditions is obtained. The variance of the reflection area of ​​each sub-cycle in a single cycle is calculated. The mean variance of each cycle is calculated to obtain the preset time-domain dispersion standard threshold.

[0077] In this invention, when the reflection area of ​​the photovoltaic module to the surrounding buildings fluctuates significantly within each sub-cycle, it is determined that the reflection degree of the photovoltaic module to the buildings is greatly affected by changes in the light source. It is then determined that there are time periods with high reflection intensity for individual photovoltaic modules, and these time periods are marked to facilitate subsequent adjustment of the parameters of the photovoltaic modules during those time periods, thereby reducing light pollution.

[0078] Please see Figure 4 As shown, it is a flowchart for determining the reasons for unqualified layout.

[0079] Specifically, if the reason for the unqualified deployment is determined to be the influence of the illumination angle on the reflection of the photovoltaic modules, sub-periods with a reflection area higher than a preset value are selected to identify strong reflection sub-periods. Based on the distribution of strong reflection sub-periods, the reasons for the unqualified deployment are analyzed, including:

[0080] If the strong reflective sub-period distribution is discrete, the reason for the unqualified layout is determined based on the number of photovoltaic modules.

[0081] If the strong reflective sub-periods are concentrated, the reason for the unqualified layout is that the amount of sample data used for illumination simulation is insufficient, and more sample data should be added.

[0082] Specifically, under the condition of determining to increase sample data, the ratio of strong reflection sub-periods to the total number of self-periods is calculated to obtain the proportion of strong reflection sub-periods. Sample data for illumination simulation is obtained based on big data, and the sample data is increased according to the proportion of strong reflection sub-periods. The increase in sample data is positively correlated with the proportion of strong reflection sub-periods.

[0083] Specifically, under the condition of determining the reasons for non-compliance in photovoltaic (PV) installation based on the number of PV modules, PV modules exhibiting reflection are identified and marked based on the reflection areas. These marked PV modules are designated as reflective modules. The number of reflective modules is counted, and the ratio of the number of reflective modules to the total number of PV modules is calculated. Based on this ratio, the reasons for non-compliance in installation are analyzed, including:

[0084] If the ratio is less than or equal to the first preset ratio standard threshold, the reason for the unqualified layout is that the installation of the reflective component is unqualified, and the installation angle of the reflective component is adjusted.

[0085] If the ratio is greater than the first preset ratio standard threshold and less than or equal to the second preset ratio standard threshold, then a secondary determination is made based on the distribution of the reflective components to determine the reason for the unqualified deployment.

[0086] If the ratio is greater than the second preset ratio standard threshold, the reason for the unqualified deployment is determined to be a problem with the deployment of photovoltaic modules, and the deployment area is redefined.

[0087] Specifically, in this embodiment, the first preset ratio standard threshold is selected between the interval [0.5, 0.6], and the second preset ratio standard threshold is selected between the interval [0.75, 0.85].

[0088] In this invention, considering that the more photovoltaic modules there are, the easier it is to generate reflection, the reflective photovoltaic modules are determined based on the emission of the photovoltaic modules. The proportion of reflective photovoltaic modules is determined based on the ratio of the number of reflective photovoltaic modules to the total number of photovoltaic modules. The reasons for unqualified photovoltaic module layout are analyzed based on the proportion. When the proportion is low, the photovoltaic module is judged to be unqualified and the installation angle of the photovoltaic module is adjusted to reduce light pollution.

[0089] Specifically, the secondary determination of the reasons for unqualified deployment based on the distribution of the reflective components includes:

[0090] If the reflective components are scattered, the reason for the unqualified layout is that the reflective components are not installed properly, and the installation angle of the reflective components is adjusted.

[0091] If the reflective components are concentrated in one area, the reason for the unqualified layout is determined to be a problem with the layout of the photovoltaic components, and the layout area should be redefined.

[0092] Specifically, after adjusting the installation angle of the reflective components, a three-dimensional model of the photovoltaic components is reconstructed according to the adjusted parameters. The power generation of the reconstructed three-dimensional model is recorded, and an analysis is conducted based on the power generation to determine whether to supplement the photovoltaic components, including:

[0093] If the power generation is lower than the preset power generation standard threshold, it is determined that additional photovoltaic modules are needed;

[0094] If the power generation exceeds the preset power generation standard threshold, it is determined that no additional photovoltaic modules will be added.

[0095] Specifically, in this embodiment, the preset power generation standard threshold is determined based on big data. The power generation standard of the current photovoltaic module is determined based on big data, and the preset power generation standard threshold is 0.95 to 1.2 times the power generation standard.

However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of the present invention.
