Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic energy storage, and particularly relates to a method and system for adjusting the angle of a photovoltaic panel and a computer-readable medium. Background Art

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect at the semiconductor interface. It mainly consists of three major parts: a photovoltaic panel, a controller, and an inverter, and the main components are composed of electronic components. Solar cells can be encapsulated and protected after being connected in series to form large-area solar cell modules, and then combined with components such as a power controller to form a photovoltaic power generation device.

[0003] During the application process of photovoltaic panels, a large number of photovoltaic panels are paved on a large panel, which easily causes a large area to be occupied, and the occupation of a large amount of land will also result in a waste of land resources. Due to different latitudes and longitudes, the sunrise and sunset times of the sun will also vary, and the intensity of sunlight on the photovoltaic panels changes greatly; in addition, there are differences in terrain. Especially in some hilly areas, the terrain has pits and bumps and different heights. If the photovoltaic panels are installed at the same height and inclination, the photovoltaic panels will block each other, resulting in low power generation efficiency. Summary of the Invention

[0004] Based on the above situation, the present invention proposes a method for adjusting the angle of a photovoltaic panel, adopting a precise azimuth sensor scheme for the photovoltaic panel. It can automatically adjust the orientation of the photovoltaic panel according to the difference in the installation height of the photovoltaic panel, thereby avoiding mutual occlusion between the photovoltaic panels.

[0005] The present invention discloses a method for adjusting the angle of a photovoltaic panel, which includes obtaining the three-dimensional coordinates, the width of the photovoltaic panel, and the relative position between two adjacent rows of photovoltaic panels; obtaining the solar incident angle of the photovoltaic panel; calculating the effective width of each photovoltaic panel that is not blocked according to the three-dimensional coordinates, the width of the photovoltaic panel, the relative position, and the solar incident angle; obtaining the total power generation of the photovoltaic panel according to the effective width of each photovoltaic panel; and determining whether the total power generation is the maximum. If so, adjusting the photovoltaic panel according to the angle of the photovoltaic panel when the total power generation is the maximum.

[0006] The step of determining whether the total power generation is the maximum specifically includes: traversing the angle combinations of each photovoltaic panel and selecting the maximum value of the total power generation of the angle combinations as the maximum value.

[0007] Detecting whether the difference between the total power generation and the actual output power generation is greater than a first preset threshold; if so, adjusting the angle of the photovoltaic panel row by row to obtain the actual output power generation of this row; when the difference between the total power generation of this row and the actual output power generation of this row is greater than a second preset threshold, it is determined that the photovoltaic panel row is abnormal.

[0008] If the row of photovoltaic panels has an abnormality, adjust the angle of each photovoltaic panel one by one to obtain the actual output power generation of this panel; when the difference between the total power generation of this panel and the actual output power generation of this panel is greater than the third preset threshold, it is determined that this photovoltaic panel has an abnormality.

[0009] The steps to obtain the angle of the photovoltaic panel when the total power generation is the largest include: the solar altitude angle is θ, the width of the photovoltaic panel is D, the three-dimensional coordinates of the row of photovoltaic panels are obtained as (X i , Y i , Z i ), the angles α i of each row of photovoltaic panels are obtained, the solar incident angles β i of each row of photovoltaic panels are obtained, where β i = α i + θ, and then the power generation power η i per unit length can be obtained according to the performance of the photovoltaic panel;

[0010] Calculate the vertical / horizontal distance between the fixed points of adjacent rows of photovoltaic panels:

[0011] L i，i+1 = f(X i , Y i , Z i , X i+1 , Y i+1 , Z i+1 ), H i，i+1 = g(X i , Y i , Z i , X i+1 , Y i+1 , Z i+1 )

[0014] Obtain the total power generation P:

[0015]

[0016] Solve to obtain the angles of each row of photovoltaic panels

[0017] The present invention also discloses a photovoltaic panel angle adjustment device, which includes a positioning data acquisition module, a photovoltaic panel information module, a power generation calculation module, and an angle adjustment module; each module is connected by signals; the positioning data acquisition module is used to acquire the three-dimensional coordinates of each photovoltaic panel, the width of the photovoltaic panel, and the relative position between two adjacent rows of photovoltaic panels; the photovoltaic panel information module is used to acquire the solar incident angle of each photovoltaic panel; the power generation calculation module is used to calculate the effective width of each photovoltaic panel that is not blocked according to the three-dimensional coordinates, the width of the photovoltaic panel, the relative position, and the solar incident angle; and calculate the total power generation of the photovoltaic panel according to the effective width of each photovoltaic panel; the angle adjustment module is used to adjust each of the photovoltaic panels according to the angle of the photovoltaic panel when the total power generation is determined to be the maximum.

[0018] Some technical effects of the present disclosure are as follows: By using a precise azimuth sensor for photovoltaic panels and considering the differences in the installation heights of photovoltaic panels, on the one hand, the time for automatically adjusting the orientation of photovoltaic panels can be effectively reduced through system traversal calculation, the mutual shading between photovoltaic panels can be reduced, and the power generation of photovoltaic panels per unit time can be increased. At the same time, it can automatically detect whether there are faults in the photovoltaic panels and automatically adjust the angle according to the fault situation to obtain the maximum power generation under fault conditions.

[0023] The technical means or technical effects involved in the present disclosure will be further described below. Obviously, the provided embodiments are only part of the implementation manners of the present disclosure, not all. Based on the embodiments and the explicit or implicit content in the drawings of the present disclosure, all other embodiments that those skilled in the art can obtain without creative efforts will be within the protection scope of the present disclosure.

[0024] As Figure 1 shown, the method in this embodiment includes the steps:

[0025] S1: Obtain the three-dimensional coordinates, the width of the photovoltaic panel, and the relative position between two adjacent rows of photovoltaic panels of each photovoltaic panel; obtain the solar incident angle of each photovoltaic panel.

[0026] The installation scenarios for photovoltaic panel power generation include installation in open grasslands, on the rooftops of high-rise buildings, and in hilly areas. In order to maximize power generation as much as possible, the installation density should be as high as possible, which inevitably leads to shading. To improve the power generation efficiency of photovoltaic panels with the same installation area, an intelligent angle adjustment system can be installed on the photovoltaic panels to improve power generation efficiency. The intelligent angle adjustment system includes an azimuth sensor and a Beidou high-precision positioning module, which are responsible for collecting the angle, vibration amplitude, and precise three-dimensional position information of the photovoltaic panel support; a DC motor and a controller: receiving instructions to adjust the angle of the photovoltaic panel support, thereby adjusting the orientation of the photovoltaic panel; a local controller: responsible for receiving data from the azimuth sensor within a certain range and transmitting the data to the cloud platform, and also receiving instructions from the cloud platform and distributing the instructions to the DC motor control unit; the cloud platform: responsible for calculating the optimal orientation plan for each solar panel based on the data collected by each sensor and the position information of the sun through data modeling, and sending instructions to notify the DC motor to adjust the attitude of the photovoltaic panel support; the high-precision positioning module can collect the high-precision position information of the photovoltaic panel support (photovoltaic panel) in real time through the Beidou satellite navigation system and the Beidou ground-based augmentation system, and accurately calculate the installation position and height information of the photovoltaic panel. At the same time, adding an IMU inertial sensor can detect the tilt angle of the photovoltaic panel and the vibration amplitude and vibration frequency in the X, Y, and Z directions of the photovoltaic panel.

[0027] As Figure 2 shown, since each row of photovoltaic panels is installed compactly and parallelly, the approximate relative position of each row of photovoltaic panels can be obtained by taking a cross-section and intercepting one photovoltaic panel in each row. For the current solar altitude angle θ, extract the reference points of each row of photovoltaic panels (which can be the support points of the photovoltaic panel or better recognition points on the photovoltaic panel). Extract three reference points A, B, and C from three of the rows and define their three-dimensional coordinates (high-precision positioning coordinates) as (X1, Y1, Z1), (X2, Y2, Z2), (X3, Y3, Z3); similarly, extract the i reference points of the i-th row and define their three-dimensional coordinates as (X i , Y i , Z i ). In this way, the vertical / horizontal distance between the reference points of two adjacent rows of photovoltaic panels can be calculated through coordinate conversion. At the same time, obtain the angle α i of each row of photovoltaic panels and the solar incident angle β i, the corresponding photoelectric conversion efficiency of the photovoltaic panel is η and the width D of the photovoltaic panel are obtained by looking up a table; based on the width D of the photovoltaic panel, the solar altitude angle θ, and the coordinate relationship of the reference points of two adjacent rows of photovoltaic panels, the ineffective width D of the unobstructed part of the photovoltaic panel can be calculated and obtained. 无效 。

[0028] S2: Calculate the effective widths of the unobstructed parts of the respective photovoltaic panels according to the three-dimensional coordinates, the width of the photovoltaic panel, the relative position, and the solar incident angle.

[0029] The parameters in step S1 can be used to calculate the incident angle and the power generation:

[0030] β i =α i +θ. According to the performance of the photovoltaic panel, the power generation η per unit length corresponding thereto can be found. i ;

[0031] Regarding the vertical / horizontal distance between the fixed points of two adjacent rows of photovoltaic panels:

[0032] L i，i+1 =f(X i ,Y i ,Z i ,X i+1 ,Y i+1 ,Z i+1 ), H i，i+1 =g(X i ,Y i ,Z i ,X i+1 ,Y i+1 ,Z i+1 );

[0033] Regarding the width of the part of the i-th row of photovoltaic panels blocked by the (i - 1)-th row, that is, the ineffective width of the i-th row of photovoltaic panels:

[0034] And its effective width D_effective = D - D 无效 ;

[0035] Among them, the total power generation P is the photoelectric conversion rate ηi of each row of photovoltaic panels. Generally, it has a certain relationship with the solar incident angle and the angle of the photovoltaic panel. When the angle of the photovoltaic panel is different, the photoelectric conversion rate will be slightly different. The formula in this embodiment is set based on the slight differences in the photoelectric conversion efficiency of each row (which requires significant lookup table adjustment according to the actual situation). Therefore, only the effective width of the photovoltaic panel irradiated by the sun needs to be known to calculate the total power generation. In the actual use process, this photoelectric conversion efficiency can be approximately regarded as a constant value by ignoring the angle differences of some photovoltaic panels. Therefore, only the effective width of the photovoltaic panel irradiated by the sun needs to be known to calculate the total power generation.

[0036] Regarding the total photoelectric conversion rate P:

[0037]

[0038] That is:

[0039] (Note: In engineering, the iterative solution method is used. Set a sufficiently small residual threshold value ε. When is obtained, the angle at which the conversion rate η approaches the maximum is obtained as the optimal solution).

[0040] As an example actually implemented in engineering, due to the limitation of the adjustable angle of the photovoltaic panel controlled by the stepper motor, the angles of each photovoltaic panel are adjusted in a step-by-step mode, that is, there is a minimum single adjustment angle ε, and the adjustment angle is an integer multiple of ε, and the adjustment range is: -90° to 90°; therefore, each photovoltaic panel can have different angle selection options. For n rows of independently adjustable photovoltaic panels, there are N n different combinations. In the process of obtaining the optimal solution for each photovoltaic panel, an algorithm will be used to traverse these N n angle setting combinations, calculate the total power generation of all photovoltaic panels under each combination, find the angle combination corresponding to the maximum power generation, and obtain the optimal solution of the angle setting.

[0041] S3. Calculate and obtain the total power generation of the photovoltaic panels according to the effective width of each photovoltaic panel; obtain the angle combination of the photovoltaic panels when the total power generation is the largest, and adjust the photovoltaic panels according to the angle combination.

[0042] From step S2, there are two methods to find the angle of the photovoltaic panel when the total power generation is the largest:

[0043] The first is to solve When the total power generation of all photovoltaic panels is the largest, the angles of each photovoltaic panel can be obtained The optimal solution (i.e., the angle combinations of each photovoltaic panel), and then adjust each photovoltaic panel according to the angle optimal solution. In this way, the total power generation of all photovoltaic panels can be maximized and adjusted according to the change of time and the solar altitude angle, achieving the purpose of optimally using all photovoltaic panels. The second limitation of adjusting the adjustable angle of the photovoltaic panel based on the stepper motor is that the angle adjustment of each photovoltaic panel is a step-by-step adjustment mode, that is, there is a minimum single adjustment angle ε, and the adjustment angle is an integer multiple of ε. When the adjustment range is: -90° to 90°, the algorithm can be used to traverse N n kinds of angle setting combinations, calculate the total power generation of all photovoltaic panels under each combination, find the angle combination corresponding to the maximum power generation, and obtain the optimal solution of the angle setting. Then adjust the angles of each photovoltaic panel according to the optimal solution of the angle setting.

[0044] The core of these two methods is to obtain the maximum total power generation of the photovoltaic panels to adjust the angles of the photovoltaic panels. In this way, through computer algorithm calculation, multiple repeated adjustments of the photovoltaic panels in actual application can be avoided, and the time for automatically adjusting the orientation of the photovoltaic panels can be effectively reduced by system traversal calculation, which is beneficial to improving the overall power generation efficiency and reducing the cost of adjusting the angles.

[0045] In actual application scenarios, there may be various adverse situations for photovoltaic panels. For example, foreign objects block the photovoltaic panels and some photovoltaic panels fail, resulting in abnormal power generation. At this time, the angle combinations of each photovoltaic panel obtained by algorithm calculation may no longer be the maximum power generation. It is necessary to detect the faulty photovoltaic panel and readjust the angle combinations of each photovoltaic panel. Detect whether the difference between the total power generation and the actual output power generation is greater than the first preset threshold; if so, adjust the angles of the photovoltaic panels row by row to obtain the actual output power generation of this row. The value of the first threshold corresponds to the total power generation, and its value is relatively large.

[0046] Generally speaking, there will be a certain deviation between the total power generation and the actual output power generation, but these deviations are within a relatively reasonable value range. Once it exceeds the reasonable value range, it may be that some photovoltaic panels are faulty. Without excluding the faulty photovoltaic panels, it is difficult to always obtain the maximum total power generation, and the faulty photovoltaic panels will also affect obtaining the optimal angle combination of the photovoltaic panels.

[0047] The following is a method to quickly find the abnormal photovoltaic panels: When the difference between the total power generation of this row and the actual output power generation of this row is greater than the second preset threshold, it is judged that the photovoltaic panels in this row are abnormal. The value of the second threshold corresponds to the power generation of a row of photovoltaic panels, and its value is relatively moderate.

[0048] If the photovoltaic panels in the row are abnormal, adjust the angles of the photovoltaic panels one by one to obtain the actual output power generation of each panel; when the difference between the total power generation of the panel and the actual output power generation of the panel is greater than the third preset threshold, it is determined that the photovoltaic panel is abnormal. The third threshold here corresponds to the power generation of a single photovoltaic panel and has the relatively smallest value. Engineering personnel can quickly locate the faulty photovoltaic panel based on the system troubleshooting situation, and then repair and troubleshoot it. When the corresponding repair cannot be found in a short time, according to the position of the faulty photovoltaic panel, the area of other photovoltaic panels it blocks can be minimized, and the sub-combination of photovoltaic panel angles when the sub-total maximum power generation is obtained can be re-traversed.

[0049] As Figure 3 shown, this embodiment further includes a photovoltaic panel angle adjustment device, including a positioning data acquisition module, a photovoltaic panel information module, a power generation calculation module, and an angle adjustment module; each module is signal-connected;

[0050] The positioning data acquisition module is used to obtain the three-dimensional coordinates, the width of the photovoltaic panel, and the relative position between two adjacent rows of photovoltaic panels of each photovoltaic panel; the photovoltaic panel information module is used to obtain the solar incident angle of each photovoltaic panel; the power generation calculation module is used to calculate the effective width of each unobstructed photovoltaic panel according to the three-dimensional coordinates, the width of the photovoltaic panel, the relative position, and the solar incident angle; and calculate the total power generation of the photovoltaic panel according to the effective width of each photovoltaic panel; the angle adjustment module is used to adjust each of the photovoltaic panels according to the angle of the photovoltaic panel when the total power generation is determined to be the maximum. The step of determining whether the total power generation is the maximum is specifically: traverse the angle combinations of each photovoltaic panel, and select the maximum value of the total power generation in each combination as the maximum value.

[0051] Detect whether the difference between the total power generation and the actual output power generation is greater than the first preset threshold; if so, adjust the angles of the photovoltaic panels row by row to obtain the actual output power generation of each row; when the difference between the total power generation of the row and the actual output power generation of the row is greater than the second preset threshold, it is determined that the photovoltaic panels in the row are abnormal.

[0052] If the photovoltaic panels in the row are abnormal, adjust the angles of the photovoltaic panels one by one to obtain the actual output power generation of each panel; when the difference between the total power generation of the panel and the actual output power generation of the panel is greater than the third preset threshold, it is determined that the photovoltaic panel is abnormal.
