[0044] like Figure 1 As shown in the figure, a photovoltaic module arrangement method provided by an embodiment of the present invention can be applied to bifacial photovoltaic modules, including:

[0045] Step S110: Determine one layout parameter of the photovoltaic module as a variable, and the other layout parameters as fixed quantities.

[0046] Specifically, layout parameters include, but are not limited to, the tilt angle and ground clearance of photovoltaic (PV) modules, as well as the spacing between PV modules and adjacent rows of PV modules. For example, the orientation of the PV modules may also be included, and these parameters can be randomly determined variables or fixed quantities. For instance, if the tilt angle of the PV modules is determined as a variable, then the ground clearance of the PV modules (which can be the ground clearance of the lowest point or the center point of the PV module) and the spacing between adjacent rows of PV modules are fixed quantities. For bifacial PV modules, in addition to power generation from direct sunlight, power can also be generated through ground reflection. Different ground surfaces have different reflectivities, resulting in different power generation from PV modules at different ground clearances.

[0047] Step S120: Repeat the optimization step multiple times to determine the maximum power generation value of the photovoltaic module and the value of the variable corresponding to each of the fixed quantities taking multiple sets of different values. The optimization step includes determining a set of values ​​for each of the fixed quantities, adjusting the value of the variable, obtaining the power generation of the photovoltaic module when the variable takes different values, and determining the maximum power generation value and the value of the variable corresponding to the maximum power generation value based on all the obtained power generation values.

[0048] For example, first, fixed values ​​such as the height of a set of photovoltaic (PV) modules from the ground and the spacing between them and adjacent rows of PV modules are determined. Then, the tilt angle of the PV modules is adjusted. The power generation of the PV modules will change with the tilt angle. The power generation of the PV modules after each tilt angle adjustment is obtained. This process is repeated multiple times to obtain the power generation of the PV modules with different tilt angle values. By comparing the power generation values, the maximum power generation of the PV modules under the fixed values ​​and the corresponding tilt angle can be determined. The fixed values ​​of the height of a new set of PV modules from the ground and the spacing between them and adjacent rows of PV modules are determined again, and the above steps are repeated to determine the maximum power generation of the PV modules under the new set of fixed values ​​and the corresponding tilt angle. By determining the fixed values ​​of multiple sets of PV modules and repeating the above steps, the maximum power generation of the PV modules and the corresponding tilt angles under each set of fixed values ​​can be determined.

[0049] Step S130: Determine the maximum power generation of the photovoltaic module based on all the maximum power generation values, and arrange the photovoltaic module according to the values ​​of each of the layout parameters corresponding to the maximum power generation.

[0050] Specifically, the maximum power generation of the photovoltaic module is determined from all the maximum power generation values, and the values ​​of layout parameters such as tilt angle, ground clearance, and spacing between adjacent photovoltaic modules are determined corresponding to the maximum power generation.

[0051] For example, assuming the maximum power generation P1 corresponds to a photovoltaic module tilt angle of φ1, the spacing between two adjacent rows of photovoltaic modules is L1, and the height above the ground is H1, the corresponding array is (P 1， Similarly, it also includes (P) φ1, L1, H1). 2， φ2, L2, H2), ..., (P n， φ n L n H n Based on these arrays, establish a matrix relating photovoltaic module power generation to tilt angle, height, and spacing:

[0052]

[0053] Furthermore, a formula can be established to relate the power generation of photovoltaic modules to their tilt angle, height above ground, and spacing between adjacent rows of photovoltaic modules:

[0054] P = f(φ) + f(L) + f(H),

[0055] Where P represents the power generation of the photovoltaic module, f(φ) is the functional relationship between the power generation of the photovoltaic module and the tilt angle, f(L) is the functional relationship between the power generation of the photovoltaic module and the spacing between the front and rear rows of photovoltaic modules, and f(H) is the functional relationship between the power generation of the photovoltaic module and the height above the ground. The maximum power generation of the extreme photovoltaic modules can be determined by dimensionality reduction methods, for example, by comparing P1, P2...P n The size of the value is the maximum power output of the photovoltaic module.

[0056] In this embodiment, one layout parameter is randomly selected as a variable from all layout parameters of the photovoltaic module. All other layout parameters are fixed values. A set of fixed values ​​is determined, and the variable values ​​are adjusted multiple times to obtain the power generation of the photovoltaic module when the variable takes different values. From all the obtained power generation values, the maximum power generation value of the photovoltaic module and the corresponding variable value are determined. Multiple sets of fixed values ​​are repeatedly determined, and for each set of fixed values, the above process is repeated to obtain the maximum power generation value and the variable value corresponding to each set of fixed values. The maximum power generation of the photovoltaic module and the values ​​of each parameter corresponding to the maximum power generation can be determined from all the maximum power generation values. The technical solution of this invention can be applied to photovoltaic modules in various application scenarios and meteorological environments. Compared to manually calculating layout parameters based on historical experience, it has a higher degree of automation, improving the calculation efficiency and accuracy of photovoltaic module layout parameters when obtaining maximum power generation benefits, thereby improving the arrangement efficiency and power generation benefits of photovoltaic modules.

[0057] Optionally, before repeatedly performing the optimization step multiple times, the method further includes:

[0058] The numerical range of each layout parameter of the photovoltaic module is determined according to a preset correspondence based on the historical surface reflectance of the area where the photovoltaic module is located. The correspondence includes the corresponding historical surface reflectance and the numerical range of each layout parameter.

[0059] Specifically, historical surface reflectance can be the average surface reflectance of the area where the photovoltaic module is located over a period of time. In the correspondence, each historical surface reflectance corresponds to a set of layout parameter values.

[0060] In this optional embodiment, the numerical range of each layout parameter is determined by the historical surface reflectance of the area where the photovoltaic module is located. Adjusting the layout parameters within this range can improve the efficiency of determining the final layout parameters and shorten the deployment cycle of the photovoltaic module.

[0061] Optionally, before repeatedly performing the optimization step multiple times, the method further includes:

[0062] For each of the layout parameters, a set of values ​​for each of the other layout parameters is randomly determined.

[0063] The layout parameters are adjusted multiple times to obtain the power generation of the photovoltaic module after each adjustment.

[0064] The power generation change trend corresponding to the layout parameters is determined based on the values ​​of the layout parameters and the power generation of the photovoltaic modules.

[0065] For example, assuming the layout parameters include the tilt angle of the photovoltaic modules, their height above the ground, and the spacing between adjacent rows of photovoltaic modules, then for the tilt angle of the photovoltaic modules, the value of the height above the ground of the photovoltaic modules and the value of the spacing between adjacent rows of photovoltaic modules are randomly determined. Then, the tilt angle of the photovoltaic modules is adjusted multiple times, and the power generation of the photovoltaic modules corresponding to each adjustment is obtained. Based on the obtained power generation of multiple photovoltaic modules, the trend of power generation change with the change of the photovoltaic module tilt angle can be determined, resulting in... Figure 2 The graph shows the relationship between the power generation of the photovoltaic module and the tilt angle. Similarly, for the height of the photovoltaic module above the ground and the spacing between two adjacent rows of photovoltaic modules, the power generation trend of the photovoltaic module with changes in height above the ground and the power generation trend of the photovoltaic module with changes in spacing can be determined, resulting in the following... Figure 3 The graph showing the relationship between the power generation of photovoltaic modules and their height above the ground is shown below. Figure 4 The graph shown shows the relationship between the power generation of photovoltaic modules and their spacing.

[0066] In this optional embodiment, by obtaining the power generation of the photovoltaic module when adjusting the value of a single layout parameter, the trend of the photovoltaic module's power generation with the change of a single layout parameter can be determined. This trend can guide the adjustment direction of the layout parameters and improve the efficiency of each layout parameter when obtaining the maximum power generation of the photovoltaic module.

[0067] Optionally, adjusting the value of the variable includes: adjusting the value of the variable within the corresponding numerical range according to the corresponding trend of power generation change;

[0068] Specifically, by adjusting the values ​​of variables in the direction of increasing power generation within the corresponding numerical range according to the trend of power generation change of the variables, the maximum power generation of photovoltaic modules can be quickly determined, avoiding the time waste caused by random adjustments, thereby improving the efficiency of determining the final layout parameters.

[0069] Optionally, determining a set of values ​​for each of the fixed quantities includes: each time the optimization step is performed, for each fixed quantity, determining the value of the fixed quantity within the corresponding value range based on the power generation change trend corresponding to the fixed quantity.

[0070] Specifically, for each fixed quantity, the value of the fixed quantity is adjusted within the corresponding range along the direction of increasing power generation, based on the trend of power generation change corresponding to that fixed quantity. This avoids wasting time due to blind adjustment and improves efficiency.

[0071] Optionally, arranging the photovoltaic modules according to the values ​​of each of the layout parameters corresponding to the maximum power generation includes:

[0072] The values ​​of each of the layout parameters are determined for the photovoltaic module to achieve the maximum power generation under various weather conditions.

[0073] Specifically, the maximum power generation of photovoltaic (PV) modules under different weather conditions, such as sunny, cloudy, rainy, and snowy days, and the corresponding values ​​of various layout parameters, need to be determined. Different weather conditions result in varying sunlight intensity, leading to different power generation from PV modules. For example, in snowy weather, snow accumulation on the surface of PV modules directly affects their power generation efficiency. Snow on the ground also alters surface reflectivity, further impacting the efficiency of the PV modules. Therefore, it is necessary to adjust the tilt angle and height of the PV modules to maximize power generation.

[0074] The photovoltaic bracket of the photovoltaic module is adaptively adjusted according to the values ​​of the various layout parameters under various weather conditions.

[0075] Optionally, the step of adaptively adjusting the photovoltaic mounting bracket of the photovoltaic module according to the values ​​of each of the layout parameters under various determined weather conditions includes:

[0076] When the photovoltaic support is a fixed support, the probability of occurrence of various weather conditions in the area where the photovoltaic module is located is determined, and the optimal value and / or adjustment range of each layout parameter is determined according to the probability of occurrence of each weather condition and the value of each layout parameter corresponding to each weather condition. The photovoltaic support is then adjusted according to the optimal value and / or adjustment range of each layout parameter.

[0077] Specifically, when the photovoltaic (PV) support is a fixed support, it is not convenient to adjust it in real time. Furthermore, the layout parameters of the PV modules may differ depending on the weather conditions to achieve maximum power generation. For example, the tilt angle of the PV modules might be A on a sunny day and B on a cloudy day. Therefore, it is necessary to determine the optimal values ​​for each layout parameter of the PV modules based on the weather conditions of the area where the PV modules are located, so that the overall power generation of the PV modules is maximized over a period of time (such as a year) under various weather conditions. To facilitate adjustment, a numerical adjustment range can be determined, including this optimal value. For example, the optimal value plus or minus a preset threshold can form the numerical adjustment range.

[0078] This system can obtain the probability of different weather conditions occurring in the area where photovoltaic (PV) modules are located, as well as the values ​​of various layout parameters for PV modules to achieve maximum power generation under different weather conditions. Weights can be assigned to different weather conditions based on their probability of occurrence, or directly using the probability of occurrence as the corresponding weight. The optimal values ​​for each layout parameter can then be determined based on the corresponding weight and the value of the corresponding layout parameter. For example, assuming the area where the PV modules are located is a desert, the probability of sunny days in a desert is 80%, corresponding to a tilt angle A for PV modules to achieve maximum power generation; the probability of cloudy days is 18%, corresponding to a tilt angle B for PV modules to achieve maximum power generation; and the probability of rainy days is 2%, corresponding to a tilt angle C for PV modules to achieve maximum power generation. If the probability of occurrence is directly used as the corresponding weight, the optimal value for the tilt angle of the PV modules is 80%A + 18%B + 2%C. Since sunny days are predominant in deserts, this optimal value, or the range of tilt angle values, can be appropriately adjusted based on the tilt angle A during sunny days.

[0079] When the photovoltaic support is an adjustable support, the weather in the area where the photovoltaic module is located is obtained in real time, and the photovoltaic support is adjusted according to the values ​​of each of the layout parameters corresponding to the real-time weather.

[0080] Specifically, when the photovoltaic (PV) mounting system is adjustable, the values ​​of various layout parameters corresponding to the current weather conditions can be adjusted in real time. For example, if the area where the PV mounting system is located is currently experiencing sunny weather, the PV mounting system will be adjusted according to the values ​​of various layout parameters corresponding to the maximum power generation achieved on sunny days.

[0081] In this optional embodiment, the photovoltaic support of the photovoltaic module is adaptively adjusted according to the values ​​of the layout parameters under various weather conditions, which can maximize the overall power generation of the photovoltaic module under different weather conditions and improve the power generation efficiency.
