step S10, determining a width function of an arrangeable area in a target roof, determining a first maximization function corresponding to the total row number of photovoltaic modules in the target roof, and determining a second maximization function corresponding to an operation and maintenance channel;
In this embodiment, the number of photovoltaic modules in the roof photovoltaic power station may be the product between the total number of rows of photovoltaic modules and the total number of columns of photovoltaic modules, and in this embodiment, the total number of rows of photovoltaic modules is exemplified, and a multi-objective planning manner is adopted, so that the maximization of the total number of rows in the roof is considered, and meanwhile, the maximization of the operation and maintenance channel is considered, so that operation and maintenance personnel can pass through the photovoltaic array conveniently. The total column number of the photovoltaic modules can be calculated and determined in the same way as the total column number of the photovoltaic modules is obtained.
Alternatively, a general plan view with roof images may be acquired prior to photovoltaic module placement. The global plan is then preprocessed to determine the image area of the target roof in the global plan (hereinafter referred to as the target roof), and the width function of the arrangeable area in the target roof. Alternatively, the target roof may be shaded to determine a shaded area, from which an arrangeable area is determined. And then constructing a straight line perpendicular to the ridge line, translating, and taking the absolute value distance between two intersection points of the translated straight line and the boundary of the arrangeable area as a width function. Since the straight line can be translated multiple times and there are shadow areas, there will be multiple different absolute distances, i.e. multiple width functions.
Optionally, the step of determining a first maximization function corresponding to the total number of photovoltaic modules in the target roof and determining a second maximization function corresponding to the operation and maintenance channel includes:
step x, setting a first objective function, and taking the first objective function as a first maximized function, wherein the first objective function is thatmaxf 1 (X) represents the function value of the first objective function, i T Representing the vector transposition of i, N being the minimum array row number, N being the maximum array row number, x i Representing the preset array number of the ith row of arrays;
step y, setting a second objective function, and taking the second objective function as a second maximization function, wherein the second objective function is thatmaxf 2 (X) represents the function value of the second objective function, W represents the width function, c T Representing that the vector is transposed for c, wherein c comprises the array width of each row of arrays, sum (X) expresses the element Sum in X, and X comprises the preset array number of each row of arrays after the vector is transposed.
Alternatively, let n be the smallest number of rows possible for the array, i.e., the smallest number of array rows. N is the maximum number of rows possible for the array, i.e., the maximum number of rows of the array. d is the assembly pitch of the photovoltaic assembly. D (D) min Is the minimum value of the operation and maintenance channel. h is light Component length of the photovoltaic component. And the width function W can be used as the photovoltaic module safety zone length.

For example, as shown in FIG. 2, the third row array has an array width c 3
Optionally, a first objective function corresponding to the total row number of the photovoltaic modules in the target roof may be constructed in advance, and the first objective function is used as a first maximization function, as shown in the following formula one:
optionally, a second objective function corresponding to the operation and maintenance channel when the photovoltaic modules in the target roof are arranged can be constructed in advance, and the second objective function is used as a second maximization function, as shown in the following formula II:
wherein maxf 1 (X) may represent a first maximization function. maxf 2 (X) represents a second pole maximization function. W represents a width function. Sum (X) expresses the Sum of elements in vector X. Alternatively, x may be set n ,x n+1 ,…,x N Represents the number of N, n+1, …, N rows of arrays, i.e., the number of arrays. Record x= [ X ] n ,x n+1 ,…,x N ] T . Alternatively, T represents vector transposition of elements, such as c T The representation is vector transposed of c, i T The representation transposes the vector of i.
Step S20, determining a first optimal value of the first maximization function according to a first constraint condition corresponding to the first maximization function and a roof parameter, and constructing a second constraint condition according to the first optimal value, wherein the roof parameter comprises a width function;
optionally, in the arrangement of the photovoltaic modules, it is required to preferentially ensure that the number of the photovoltaic modules is the largest, that is, the total number of the modules is the largest, and then consider to increase the operation and maintenance channels. Thus, to avoid collision of the first maximization function and the second maximization function, the priority of the first maximization function may be set higher than the priority of the second maximization function. Therefore, the first optimal value corresponding to the first maximizing function can be determined first, and then the second maximizing function is operated.
Optionally, before determining the first optimal value, a constraint condition that needs to be met by the first maximization function is constructed, and the constraint condition is used as the first constraint condition. Optionally, the first constraint condition may include an array total length constraint condition that constrains an array total length of the photovoltaic module array, an array length constraint condition that constrains each array length in the photovoltaic module array, and an operation and maintenance channel constraint condition that constrains the operation and maintenance channel. And obtaining roof parameters input by a user, inputting the roof parameters into a first constraint condition for operation to obtain an operation result, and inputting the operation result into a first maximization function to obtain a first optimal value. Optionally, the roof parameters include at least a width function of the arrangeable area. The specific operation step of the first maximization function may be operated by referring to the formula one.
Alternatively, since the first maximization function has a higher priority than the second maximization function, the second constraint may be constructed in dependence on when the first maximization function is equal to the first optimal value.
Step S30, determining a second optimal value of the second maximization function according to the first constraint condition and the second constraint condition;
alternatively, the roof parameters may be input into a second maximization function for operation to obtain a second optimal value. Optionally, the function parameters in the second maximum function meet the first constraint condition and the second constraint condition simultaneously, and on the basis, a second optimal value is obtained according to the roof parameters and the formula II.
