[0039] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.
[0040] Figure 1 A schematic diagram of the implementation process of a photovoltaic panel angle adjustment method according to an embodiment of the present disclosure is shown. Figure 1 As shown, according to a first aspect of an embodiment of the present disclosure, a method for adjusting the angle of a photovoltaic panel is provided, and the method includes:
[0041] Step 101, selecting a target panel having a risk of being blocked at a target adjustment time from all photovoltaic panels;
[0042] The photovoltaic panel is an array panel composed of photovoltaic cells. In order to enable the photovoltaic panel to obtain as much solar radiation as possible, the angle of the photovoltaic panel needs to be adjusted every preset adjustment period. The preset adjustment period can be a preset period based on the geographical location of the photovoltaic panel and the design of the photovoltaic panel, for example, it can be 1-30 minutes.
[0043] The target adjustment time is the time when the angle of the target panel is adjusted next time. Assuming that the last time the target panel was adjusted was nine o'clock and the preset adjustment cycle is 30 minutes, the target adjustment time is nine thirty; the target panel is a photovoltaic panel that may be blocked by each other after its angle is adjusted at the target debugging time.
[0044] Step 102, determining a first projection area of a target panel on a horizontal plane and a second projection area of other non-target panels except the target panel on a horizontal plane at a target adjustment moment;
[0045] The first projection area is the area formed by the projection of the target panel on the horizontal plane at the target adjustment moment, and the second projection area is the area formed by the projection of other non-target panels except the target panel on the horizontal plane at the target adjustment moment; the first projection area is related to the angle between the target panel and the horizontal plane at the target adjustment moment and the position of the sun at the target adjustment moment, and the second projection area is related to the angle between the non-target panel and the horizontal plane at the current moment and the position of the sun at the target adjustment moment.
[0046] Step 103, determining the normal vector of the plane where the target panel is located at the target adjustment time and the position vector of the sun at the target adjustment time;
[0047] The normal vector of the plane where the target panel is located at the time of target adjustment can be determined by the following formulas (1), (2), and (3):
[0048]
[0049]
[0050]
[0051] in, Represents the normal vector of the plane where the target panel is located at the time of target adjustment, θ ’ Represents the target angle, which is the value to be solved; express The component on the x-axis, express The component on the y-axis, express The component on the z-axis, γ, is the angle between the central axis of the photovoltaic panel and the horizontal plane. The position of the central axis on the photovoltaic panel is as follows: Figure 2 Shown by the dashed line.
[0052] The position vector of the sun at the target adjustment time can be determined according to the altitude angle and azimuth angle of the sun at the target adjustment time, and can be determined by the following formulas (4), (5), and (6):
[0053]
[0054]
[0055]
[0056] in, Represents the position vector of the sun at the target adjustment time, express The component on the x-axis, express The component on the y-axis, express The component on the z-axis, e ’ The altitude angle of the sun at the target adjustment time, a ’ Adjust the sun's azimuth for the target at that moment.
[0057] Step 104, determining a target angle of the target panel at the target adjustment time according to the first projection area, the second projection area, the normal vector of the plane where the target panel is located at the target adjustment time, and the position vector of the sun at the target adjustment time, so that when the target panel is adjusted to the target angle, there is no overlap between the projection areas of all photovoltaic panels;
[0058] The target angle is the angle at which the target panel rotates relative to the horizontal plane after the angle of the target panel is adjusted at the target adjustment moment; based on the first projection area and the second projection area, the minimum value of the cosine value of the angle between the normal vector of the plane where the target panel is located and the sun's position vector at the target adjustment moment is determined under the condition that there is no overlapping area between the first projection area and the second projection area, thereby determining the value of the target angle in the normal vector of the plane where the target panel is located at the target adjustment moment.
[0059] Step 105: At the target adjustment moment, adjust the target panel to the target angle.
[0060] A method for adjusting the angle of a photovoltaic panel in the present embodiment first selects a target panel that has a risk of being blocked at a target adjustment moment, and then determines the target angle based on a first projection area of the target panel on the horizontal plane at the target adjustment moment, a second projection area of other non-target panels other than the target panel on the horizontal plane, a normal vector of the plane where the target panel is located at the target adjustment moment, and a position vector of the sun, so that when the target panel is adjusted to the target angle at the target adjustment moment, there is no overlapping area between the projection areas of all the photovoltaic panels, thereby achieving no blocking between the photovoltaic panels after adjustment and improving the power generation efficiency of the photovoltaic panels.
[0061] In one embodiment of the present disclosure, a target panel with a risk of shading at a target adjustment moment is selected from all photovoltaic panels, including: determining the cosine value of the angle between the normal vector of the plane where the photovoltaic panel is located at the current moment and the position vector of the sun at the current moment; and determining the photovoltaic panel whose cosine value of the angle at the current moment is less than the angle threshold and has not failed as the target panel.
[0062] The angle threshold is the cosine value of the angle between the normal vector of the plane where the photovoltaic plane is located and the position vector of the sun. The photovoltaic panels that are not faulty refer to the photovoltaic panels that can work normally at the current moment. Specifically, which photovoltaic panels are not faulty can be obtained through the control end of the photovoltaic panels.
[0063] Specifically, the normal vector of the plane where the photovoltaic panel is located at the current moment can be determined by the following formulas (7), (8), and (9):
[0064]
[0065]
[0066]
[0067] in, Represents the normal vector of the plane where the photovoltaic panel is located at the current moment, express The component on the x-axis, express The component on the y-axis, express The component on the z-axis, θ is the angle between the photovoltaic panel and the horizontal plane at the current moment, and γ is the angle between the central axis of the photovoltaic panel and the horizontal plane at the current moment.
[0068] The current position vector of the sun can be determined by the following formulas (10), (11), and (12):
[0069]
[0070]
[0071]
[0072] in, represents the sun's position vector at the current moment, express The component on the x-axis, express The component on the y-axis, express The component on the z-axis, e is the altitude angle of the sun at the current moment, and a is the azimuth angle of the sun at the current moment.
[0073] The cosine value of the angle between the normal vector of the plane where the photovoltaic panel is located and the position vector of the sun at the current moment can be determined by the following formula (13):
[0074]
[0075] in, Represents the normal vector of the plane where the photovoltaic panel is located at the current moment, represents the sun's position vector at the current moment, express and The product of express The model and The product of the modulos.
[0076] The cosine value obtained by the above formula (13) is compared with the angle threshold, and the photovoltaic panel whose cosine value is less than the angle threshold and has not failed is determined as the target panel.
[0077] In one embodiment of the present disclosure, determining a first projection area of a target panel on a horizontal plane at a target adjustment moment includes: determining target coordinates of vertices of the target panel at the target adjustment moment in a three-dimensional coordinate system; determining coordinates of projection points of the vertices on the horizontal plane at the target adjustment moment based on the target coordinates, where the horizontal plane is an XY plane in the three-dimensional coordinate system; determining the first projection area of the target panel on the horizontal plane at the target adjustment moment based on the coordinates of the projection point.
[0078] like Figure 2 As shown, a three-dimensional coordinate system is established with due east as the X-axis, due north as the Y-axis, and the Z-axis perpendicular to the ground. The horizontal plane is the XY plane in the three-dimensional coordinate system. The target coordinates are the coordinates of the vertices of the target panel in the three-dimensional coordinate system at the time of target adjustment. The target coordinates can be determined according to the coordinates when the target panel is parallel to the horizontal plane and the target angle.
[0079] The coordinates of the projection point of the vertex on the horizontal plane at the target adjustment time can be determined by the following formulas (14) and (15):
[0080]
[0081]
[0082] (x r ,y r 、z r ) is the coordinate of the sun at the target adjustment time, which can be determined according to the time of the target adjustment time and is a known quantity; x e ,y e They represent the horizontal and vertical coordinates of the projection point respectively. Since x, y, and z contain the target angle, x e ,y e Also an expression with a target angle.
[0083] According to the coordinates of the projection point, the linear equations of the four straight lines passing through the projection point can be determined, and the projection area can be determined according to the linear equations of the four straight lines. For example, Figure 2 As shown, the four vertices of the photovoltaic panel are A, B, C, and D. Assume that the projection points corresponding to vertices A, B, C, and D are A ′ , B ′ , C ′ and D ′ , A can be obtained from the above formula ′ , B ′ , C ′ and D ′ The coordinates are expressions with target angles, according to A ′ , B ′ , C ′ and D ′ The coordinates of A are determined by′ and B ′ , B ′ and C ′ , C ′ and D ′ , D ′ and A ′ The linear equations of the four determined straight lines can be used to determine the projection area corresponding to the photovoltaic panel.
[0084] In one embodiment of the present disclosure, the target coordinates of the vertices of the target panel at the target adjustment moment in the three-dimensional coordinate system are determined, including: obtaining the initial coordinates of the vertices in the three-dimensional coordinate system when the target panel is parallel to the horizontal plane; determining the rotation matrix corresponding to the target panel at the target adjustment moment; and determining the target coordinates of the vertices based on the rotation matrix and the initial coordinates.
[0085] The initial coordinates are the coordinates of the vertices of the target panel in the three-dimensional coordinate system when the target panel is parallel to the horizontal plane. The initial coordinates can be determined based on the central axis coordinates of the target panel and the size of the target panel. The rotation matrix can be determined by the target angle. Since the current target angle is unknown, the rotation matrix is an expression with the target angle.
[0086] Specifically, the target coordinates of the vertices of the target panel in the three-dimensional coordinate system at the target adjustment time can be determined by the following formula (16):
[0087]
[0088] Among them, (x, y, z) represents the coordinates of any vertex on the target panel at the target adjustment moment, (x0, y0, z0) represents the initial coordinates of the vertex when the target panel is parallel to the horizontal plane; R is the rotation matrix, which is determined according to the target angle. R contains the target angle, so x, y, z obtained by R also contain the target angle, and the target angle is the number to be determined.
[0089] In one embodiment of the present disclosure, determining a second projection area of a non-target panel on a horizontal plane includes: determining real-time coordinates of vertices of the non-target panel at a current moment in a three-dimensional coordinate system; determining coordinates of projection points of vertices of the non-target panel at the target adjustment moment on the horizontal plane based on the real-time coordinates and the position coordinates of the sun at the target adjustment moment; and determining a second projection area of the non-target panel on the horizontal plane at the target adjustment moment based on the coordinates of the projection points of the non-target panel.
[0090] The real-time coordinates are the coordinates of other non-target panels except the target panel at the current moment, which can be specifically determined by the central axis coordinates of the non-target panel at the current moment and the size of the non-target panel; the method for obtaining the coordinates of the projection point of the non-target panel at the target adjustment moment is similar to the method for obtaining the projection point of the target panel, and will not be repeated again; the position coordinates of the sun at the target adjustment moment are the coordinates of the sun at the target adjustment moment. Since the non-target panel is not adjusted at the target adjustment moment, the projection area of the non-target panel at the target adjustment moment, that is, the second projection area is determined by the current angle between the non-target panel and the horizontal plane and the position coordinates of the sun at the target adjustment moment.
[0091] In one embodiment of the present disclosure, determining a target angle of the target panel at the target adjustment time according to the first projection area, the second projection area, the normal vector of the plane where the target panel is located at the target adjustment time, and the position vector of the sun at the target adjustment time includes:
[0092] Determine a first coefficient matrix and a first constant matrix corresponding to the target panel at the target adjustment moment according to the expression of the first projection area;
[0093] According to the expression of the second projection area, determine the second coefficient matrix and the second constant matrix corresponding to the non-target panel at the target adjustment time;
[0094] The target angle is determined according to the first coefficient matrix, the first constant matrix, the second coefficient matrix and the second constant matrix, the normal vector of the plane where the target panel is located at the target adjustment moment, and the position vector of the sun at the target adjustment moment.
[0095] In the above embodiment, it is mentioned that the straight line equations of the four straight lines where the outline of the projection area is located can be determined by the projection point coordinates;
[0096] For example, the linear equations of the four straight lines corresponding to the first projection area are:
[0097] A1x-B1y-b1=0
[0098] A2x-B2y-B2=0
[0099] A3x-B3y-b3=0
[0100] A4x-B4y-B4=0
[0101] The area enclosed by these four straight lines, namely the first projection area, is expressed as:
[0102]
[0103] Among them, A1-A4, B1-B4, b1-b4 are expressions with target angles. is the first coefficient matrix, is the first constant matrix.
[0104] The method for determining the second coefficient matrix and the second constant matrix corresponding to the non-target panel at the target adjustment moment is the same as that for the second coefficient matrix and the second constant matrix, so it will not be repeated here.
[0105] After determining the first coefficient matrix, the first constant matrix, the second coefficient matrix and the second constant matrix, the target angle can be determined by combining the normal vector of the plane where the target panel is located at the target adjustment time and the position vector of the sun at the target adjustment time;
[0106] Specifically, the target angle can be determined by the following optimization function (17):
[0107]
[0108] in, is the objective function, st is the optimization condition, i represents the i-th target panel, j represents other photovoltaic panels except the i-th target panel, N represents the number of target panels, Represents the normal vector of the plane where the i-th target panel is located at the time of target adjustment, Represents the position vector of the sun at the target adjustment time, represents the transpose of the second matrix corresponding to the i-th target panel, represents the transpose of the second matrix of the photovoltaic panels other than the i-th target panel, represents the transpose of the first matrix corresponding to the i-th target panel, represents the transpose of the first matrix corresponding to the photovoltaic panels other than the i-th target panel, μ i represents the auxiliary variable corresponding to the i-th target panel, λ j Represents the auxiliary variables corresponding to other photovoltaic panels except the i-th target panel.
[0109] For example, photovoltaic panels 1, 2 and 4 among photovoltaic panels 1-4 are target panels that have a risk of being blocked at the target adjustment moment, and photovoltaic panels 1, 2 and 4 are target panel 1, target panel 2 and target panel 3 respectively.
[0110] at this time, Where N is 3, which represents the sum of the cosine values of the angles between the normal vectors of the planes where the target panels 1, 2, and 3 are located and the position vector of the sun at the target adjustment time; represents the minimum value of the sum of the cosine values of the angle, where is a known quantity, Contains the target angles corresponding to target panels 1, 2, and 3.
[0111] Take i as an example, To illustrate, the transpose b1 of the second matrix corresponding to the target panel 1 T Multiply by the auxiliary variable μ1, and then subtract the transpose of the second matrix corresponding to the photovoltaic panels 2-4 and multiply by the corresponding auxiliary variables. μ and λ are unknown numbers without practical significance introduced to solve the optimization conditions;
[0112] Correspondingly, the data corresponding to when i is 2 and 3 are successively brought into
[0113] Take i as 3 examples, for To illustrate, when i is 3, the target panel 3 is the photovoltaic panel 4, and its corresponding is the transpose of the first matrix corresponding to target panel 3 Multiply by the auxiliary variable μ3, and then subtract the transpose of the first matrix corresponding to photovoltaic panels 1, 2, and 3 multiplied by the corresponding auxiliary variables;
[0114] Correspondingly, the data corresponding to when i is 1 and 2 are sequentially brought into
[0115] At this time, the optimization conditions in the optimization function and the unknowns contained in the objective function are the target angles corresponding to the target panels 1, 2 and 3 respectively. By solving the optimization function, the values of the target angles corresponding to the target panels 1, 2 and 3 respectively can be obtained.
