s201, acquiring meteorological data of an area where the photovoltaic assembly is located according to the position information of the photovoltaic assembly, wherein the meteorological data at least comprises irradiance data and weather types of the current time.
When the position information of the photovoltaic module is obtained, the longitude and latitude coordinates of the photovoltaic module can be obtained firstly, the position of the photovoltaic module is determined according to the longitude and latitude coordinates, and then the area where the photovoltaic module is located is determined according to the position of the photovoltaic module. The regions may be divided according to administrative regions, such as province, city, county, etc. The area where the photovoltaic module is located can be the city or county where the photovoltaic module is located, considering that the weather conditions of the city or county are similar. After the position information of the photovoltaic module is acquired, meteorological data corresponding to the position of the photovoltaic module can be acquired, the meteorological data can be acquired through a satellite or a meteorological station, the meteorological data at least comprise irradiance data and weather types of the current time, and the weather types comprise types of sunny days, rainwater weather (including rainwater weather with different rainwater intensities such as light rain, medium rain, heavy rain and heavy rain) and extreme weather (such as windy days, heavy snow days and hail days).
S202, acquiring a real-time tracking angle of the photovoltaic assembly through the angle tracking model based on the irradiance data.
In this embodiment, the angle tracking model is a pre-constructed model for obtaining the tracking angle of the photovoltaic module, and is an algorithm optimization model, which finds out the angle characteristics of high-scattering radiation changing with 12 hours every day under different weather conditions through deep learning. The angle tracking model may be obtained by: firstly, constructing an initial angle tracking model; then obtaining historical meteorological data of an area where the photovoltaic assembly is located and angle tracking data of the position where the photovoltaic assembly is located, wherein the historical meteorological data at least comprises irradiance data corresponding to weather types, data acquisition time and time; and then training the initial angle tracking model based on the historical meteorological data and the angle tracking data to obtain a trained angle tracking model, wherein the angle tracking model comprises the relation between the tracking angle of the position of the photovoltaic module and the meteorological data. It can be understood that, in order to improve the accuracy of the model, the model may be trained continuously using new training data, and as the data amount of the training data set increases continuously, the accuracy of the model may be improved continuously. After irradiance data of the position where the photovoltaic component is located and the current time are obtained, the real-time tracking angle of the photovoltaic component can be confirmed through the angle tracking model.
S203, acquiring the geographic environment information of the position of the photovoltaic module and the arrangement information of the photovoltaic module.
The geographic environment information at least comprises gradient information of the position of the photovoltaic module. After the real-time tracking angle is obtained, because the gradient of the position of the photovoltaic module is different, the actually adjusted angle of the photovoltaic module is also different, and meanwhile, the arrangement mode of the photovoltaic module is also required to be considered, so that gradient information and arrangement information are required to be obtained. In the embodiment of the disclosure, the unmanned aerial vehicle can ascend to the high altitude of the area where the photovoltaic module is located to shoot the first image information of the position where the photovoltaic module is located, and the first image information is subjected to image recognition to obtain the gradient of the position where the photovoltaic module is located and the arrangement mode of the photovoltaic module.
And S204, determining an angle adjusting strategy of the photovoltaic module through the three-dimensional terrain model based on the geographic environment information, the arrangement information, the real-time tracking angle and the meteorological data.
In this embodiment, the three-dimensional terrain model is a pre-constructed model for obtaining an adjustment angle of the photovoltaic module, and is capable of simulating a terrain where the photovoltaic module is located, and determining how to adjust the photovoltaic module based on the obtained gradient information, photovoltaic module arrangement information, meteorological data, and a real-time tracking angle.
Specifically, whether the weather type is sunny or not is determined based on the weather type of the area where the photovoltaic assembly is located.
If the weather type is clear, the weather is clear, the irradiation intensity is high at the moment, and the sunlight needs to be utilized to the maximum extent for power generation, so that the adjustment angle of the photovoltaic module is determined according to the sunshine moving track based on the slope information, the arrangement information and the real-time tracking angle, and the photovoltaic module is ensured to obtain high-scattering radiation.
If the weather type is rainwater weather, it means that solar irradiation intensity is low, whether the rainwater is utilized to clean the photovoltaic module can be considered at the moment, so that maintenance cost of the photovoltaic module is saved, and therefore the adjustment angle of the photovoltaic module is determined based on rainwater intensity, geographical environment information and arrangement information of the rainwater weather, and the photovoltaic module is cleaned by utilizing the rainwater. For example, when the rain weather is light rain (for example, light rain is defined as rainfall between 0.1 and 4.9 millimeters within 12 hours) or medium rain (for example, medium rain is defined as rainfall between 5.0 and 14.9 millimeters within 12 hours), the rain is mild and does not damage the photovoltaic module, and at this time, the rain can be fully utilized for cleaning by adjusting the angle (for example, adjusting the angle to be vertical to the falling direction of the rain or forming an angle of 45 degrees); when the rainwater weather is heavy rain (for example, heavy rain between 15.0.1-29.9 mm of rainfall in 12 hours is defined) or heavy rain, the rainwater easily damages the photovoltaic module, and at this moment, the rainwater is prevented from impacting the photovoltaic module by adjusting the angle (for example, adjusting the angle to be parallel to the falling direction of the rainwater), so that the damage to the photovoltaic module is reduced.
If the weather type is extreme weather, the solar radiation intensity is low, and the photovoltaic module is easily damaged, so that the adjusting angle of the photovoltaic module is determined based on the weather type, the gradient information and the arrangement information, so that the front impact of the photovoltaic module in the extreme weather is avoided, and the damage to the photovoltaic module is reduced. For example, for a windy day, the angle of the photovoltaic module can be adjusted according to the wind direction, so that the photovoltaic module is parallel to the wind direction, and the front impact on the photovoltaic module is avoided. For another example, the photovoltaic module can be adjusted to the vertical direction aiming at a big snow day or a hail day, and the front of the photovoltaic module cannot be impacted by snow or hail at the moment, so that the photovoltaic module can be protected.
And S205, adjusting the angle of the photovoltaic assembly based on the angle adjusting strategy.
In some embodiments, after the angle adjustment strategy is obtained, the tracking support is controlled to adjust according to the angle adjustment strategy, so that the angle adjustment of the photovoltaic module is realized.
In some embodiments, after the angle adjustment strategy of the photovoltaic module is obtained, the angle adjustment strategy can be pushed to a user and displayed to form interactive operation, the user determines whether to adjust the angle of the photovoltaic module according to the mode or receives an adjustment mode input by the user, and therefore the tracking support of the photovoltaic module is controlled to move based on the adjustment strategy determined by the user to adjust the angle of the photovoltaic module, and manual adjustment is achieved.
According to the photovoltaic module angle adjusting method, the real-time tracking angle of the photovoltaic module is obtained by obtaining meteorological data of the area where the photovoltaic module is located, meanwhile, the real-time adjusting strategy is determined based on the geographical environment information of the area where the photovoltaic module is located and the arrangement information of the photovoltaic module, so that the tracking support of the photovoltaic module is adjusted based on the real-time adjusting strategy, the photovoltaic module can be guaranteed to receive the largest effective illumination area in real time, the optimal high radiation angle is achieved, light energy can be utilized to the maximum degree, photovoltaic power generation efficiency is improved, generated energy is increased, and system power generation cost is reduced. Meanwhile, when the angle is adjusted, adjustment strategies of different weather types are fully considered, sunlight can be effectively utilized, rainwater can be utilized to clean the photovoltaic assembly, maintenance cost is reduced, damage to the photovoltaic assembly caused by extreme weather can be avoided, the damage rate of the photovoltaic assembly is reduced, and the service life is prolonged.
Furthermore, after the angle of the photovoltaic module is adjusted, the adjustment result can be checked, at the moment, second image information after the photovoltaic module is adjusted can be obtained through the unmanned aerial vehicle, image recognition is carried out based on the second image information, the arrangement mode after the photovoltaic module is adjusted is obtained, and whether the expected angle is reached is confirmed; and then optimizing the three-dimensional terrain model based on the adjusted arrangement mode of the photovoltaic modules so as to further improve the model precision.
In order to evaluate the optimization effect of the photovoltaic module adjusted according to the embodiment of the disclosure, an evaluation index system can be established according to the management requirement of the distributed photovoltaic power generation system, the indexes can include power generation capacity, temperature efficiency loss, shielding rate, module breakage rate and the like, the size relationship of the indexes of the photovoltaic modules which are not provided with the tracking support and provided with the tracking support in the same type in the past period (for example, one year) is compared, the improvement effect under the condition that the tracking support is adjusted by adopting a photovoltaic module angle adjustment method after being provided is evaluated, the income of income increase is quantified, and the reduced electricity consumption cost is evaluated. It can be understood that when the power generation amount of the distributed photovoltaic power generation system provided with the tracking support is larger than that of the distributed photovoltaic power generation system not provided with the tracking support, and the component damage rate is smaller than that of the distributed photovoltaic power generation system not provided with the tracking support, it means that the use of the tracking support in the embodiment of the present disclosure has a positive optimization effect.
In this embodiment, the module breakage rate is as one of evaluation power station index, and the fixed photovoltaic module of tradition can't follow weather and make real-time dynamic adjustment, and the photovoltaic module breakage rate is higher, and economic cost risees by a wide margin, and the tracking support can real-time control photovoltaic module's angle in this embodiment of the disclosure, carries out the adjustment strategy, greatly reduced photovoltaic module's breakage rate.
In some embodiments, the method further comprises: stopping rotating the photovoltaic assembly under the condition that the tracking angle is determined to be the low-efficiency acceptable irradiance; or when the tracking angle is determined to be the tracking angle with low power generation capacity, a system prompt is sent to remind people to adjust the tracking angle.
