Referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of a photovoltaic module partitioning method according to the present invention.
In the present embodiment, an embodiment of an interface switching method is provided, and it should be noted that although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in an order different from that here.
In order to partition a plurality of photovoltaic modules in a photovoltaic system and connect each partitioned photovoltaic module through a cable, so that the laying cost of the cable is the lowest, in this embodiment, as shown in fig. 3, first, position information of the photovoltaic modules is read, then, a determined objective function is obtained based on the position information of each photovoltaic module, and then, the objective function is optimized through a genetic algorithm to obtain an optimal partition and an optimal connection mode of the photovoltaic modules.
Step S10, based on the position parameters of the photovoltaic modules in the preset module matrix, carrying out initial partitioning on the photovoltaic modules to obtain a photovoltaic module set;
it should be noted that, in the present embodiment, the layout positions of the photovoltaic modules in the photovoltaic system are predetermined, that is, the positions of the photovoltaic modules cannot be changed. On this basis, before the plurality of photovoltaic modules are partitioned on the basis of the cable laying cost minimization principle, initial partitioning needs to be performed on each photovoltaic module.
Specifically, for example, the position parameter of the photovoltaic module may be expressed as:
X={X 1 ,X 2 ,…,X i ,…,X n }
wherein n is a squareTotal number of components in array, X i Is the position coordinate (x) of the ith photovoltaic module Xi ,y Xi )。
It should be noted that, in this embodiment, the photovoltaic modules may be uniformly grouped or non-uniformly grouped, and this grouping manner is not specifically limited in this embodiment.
Step S20, determining cable functions corresponding to the photovoltaic module sets, and determining target cable functions corresponding to the preset photovoltaic module square matrix based on the cable functions;
the terminal equipment further determines cable functions corresponding to all the photovoltaic module sets after acquiring position parameters, namely position coordinates, of all the photovoltaic modules in the photovoltaic module array and initially partitioning the photovoltaic modules according to the position coordinates to obtain the photovoltaic module sets. On the basis, the cable functions are accumulated to obtain a target cable function corresponding to the photovoltaic module array.
And step S30, based on the cable cost minimization principle, performing parameter optimization on the target cable function to obtain the optimal partition of the photovoltaic module.
It should be noted that, in this embodiment, the principle of minimizing the cable cost is that, when all the photovoltaic modules in the photovoltaic module matrix are wired by cables, the cables are used for completing the wiring of all the photovoltaic modules, so that the cost of the bus cable for the wiring is the lowest.
Specifically, for example, after each photovoltaic module in the photovoltaic module matrix is initially partitioned to obtain a photovoltaic module set, and then a target cable function of the photovoltaic module matrix is determined based on a cable function of each photovoltaic module set, in order to minimize the wiring cost, the target cable function is optimized in parameters to obtain an optimal partition of each photovoltaic module in the photovoltaic module matrix, and the total cable cost for wiring is minimized according to the optimal partition.
In this embodiment, each photovoltaic module is initially partitioned based on the position parameter of the photovoltaic module to obtain a photovoltaic module set, a cable function of each photovoltaic module set to the photovoltaic module set is determined, and the cable functions are accumulated to obtain a function of a target cable corresponding to the photovoltaic module array. In order to minimize the wiring cost, the target cable function is optimized in parameters to obtain the optimal partition of each photovoltaic module in the photovoltaic module square matrix, and the total cable cost for wiring is minimized according to the optimal partition.
Compared with the photovoltaic module partitioning wiring mode in the prior art, in the invention, the target cable function of the photovoltaic module matrix is obtained according to the cable function of the photovoltaic module set obtained by initial partitioning, and the photovoltaic module partitioning mode with the lowest cable cost of the photovoltaic modules in the photovoltaic module matrix can be obtained by carrying out parameter optimization on the target cable function. Therefore, the photovoltaic module can be wired through the cable, and the photovoltaic module partition mode with the lowest cable wiring cost can be realized. On the basis, the photovoltaic power station can further reduce the cost of the photovoltaic power station.
Based on the first embodiment of the partitioning method of the photovoltaic module of the present invention, a second embodiment of the partitioning method of the photovoltaic module of the present invention is proposed.
Compared with the first embodiment, in this embodiment, after the step S30, "performing parameter optimization on the target cable function to obtain the optimal partition of the photovoltaic module," the method further includes:
step S40, according to the optimal partition, all the photovoltaic modules in the preset module square matrix are partitioned to obtain each sub-area;
and step S50, sequentially connecting the photovoltaic modules in the sub-areas through cables.
It should be noted that, in this embodiment, after parameter optimization is performed on a target cable function by the terminal device to obtain an optimal partition of the photovoltaic module, area division of the photovoltaic module and connection of the photovoltaic module in the area are further performed according to the optimal partition, so that the total cost of cables for wiring is the lowest.
Specifically, for example, the terminal device partitions all photovoltaic modules in a preset photovoltaic module matrix according to the optimal partition to obtain each sub-area, wherein each sub-area includes a plurality of photovoltaic modules, and on the basis, the terminal device partitions all photovoltaic modules in the preset photovoltaic module matrix to obtain each sub-areaAnd the photovoltaic modules are connected in sequence according to the subscripts of the photovoltaic modules, and the cable laying cost generated by the partition and connection mode of the photovoltaic modules is the lowest. For example, in sub-region D i Including a photovoltaic module d 1 、d 2 、…、d i All photovoltaic modules within that sub-zone will be connected sequentially in the order 1, 2, …, i.
Further, in step S10, the "obtaining a photovoltaic module set by initially partitioning the photovoltaic modules" may include:
and S101, partitioning the photovoltaic modules according to the capacity of a preset header box or a preset string inverter to obtain a photovoltaic module set.
It should be noted that, in the present embodiment, all the photovoltaic modules in the photovoltaic module matrix may be partitioned by using the capacity of the combiner box or the string inverter.
Specifically, for example, the photovoltaic module is divided into m sub-regions according to the capacity of the combiner box or the group string inverter, the size of each sub-region may be different or the same, and the set of sub-regions is denoted as D ═ { D ═ D 1 ,D 2 ,…,D i ,…,D m The number of components corresponding to each sub-area is { d } 1 ,d 2 ,…,d i ,…,d m In which D is i Is the ith photovoltaic module subregion, contains d i And the photovoltaic modules are connected according to the subscript sequence.
On the basis, the set of components corresponding to each photovoltaic subregion Di is S ═ S 1 ,S 2 ,…,S i ,…,S di And (4) wherein S is equal to X, and X is a position parameter of the photovoltaic module and can be expressed as: x ═ X 1 ,X 2 ,…,X i ,…,X n }。
Further, in step S20, the "determining a cable function corresponding to each of the photovoltaic module sets" may include:
step S201, determining a Manhattan distance between adjacent photovoltaic modules according to the position parameters of each photovoltaic module in the photovoltaic module set, and determining a cable function corresponding to the photovoltaic module set according to the Manhattan distance.
The terminal equipment partitions the photovoltaic modules according to the position parameters of the photovoltaic modules, obtains a photovoltaic module set, and then connects the photovoltaic modules according to the subscripts of the modules according to the position parameters of the photovoltaic modules in the photovoltaic module set, so that the cable usage and the cable cost of the partitions can be determined.
In particular, for example, since the photovoltaic module is set to S ═ { S ═ S 1 ,S 2 ,…,S i ,…,S di At this time, the corresponding cable function is g i (S). Starting from S1 in the set S, the next connection point S is calculated respectively i And the last connection point S i-1 The Manhattan distance of, the target function of the connection mode of the components in the sub-area is
Figure BDA0003592006640000091
Wherein the content of the first and second substances,
Figure BDA0003592006640000092
further, in the step S20, the "determining the target cable function corresponding to the preset photovoltaic module square matrix based on each cable function" may include:
step S202, accumulating the cable functions of the photovoltaic modules to obtain a target cable function corresponding to the preset module matrix.
After the cable functions corresponding to the photovoltaic module sets are determined, in order to partition all photovoltaic modules of the photovoltaic module square matrix, the terminal equipment further determines target cable functions corresponding to the photovoltaic module square matrix according to the cable functions corresponding to the photovoltaic module sets.
Specifically, for example, the number of components per partition { d } 1 ,d 2 ,…,d i ,…,d m Sequentially acquiring support point sets of the sub-areas from the support point sets in a centralized manner, namely the photovoltaic assembly sets { D ] of the sub-areas 1 ,D 2 ,…,D i ,…,D m Due to the cables of each sub-areaObjective function g i (S) having determined above, based on the partitioned cable functions, a cable objective function f (x) for the photovoltaic module square matrix can be obtained as:
Figure BDA0003592006640000093
on the basis, f (X) is taken as an objective function of the system to be optimized and solved.
Further, in step S30, the "performing parameter optimization on the target cable function to obtain the optimal partition of the photovoltaic module" may include:
and S301, performing parameter optimization on the target cable function through a preset genetic algorithm based on a cable cost minimization principle to obtain an optimal partition of the photovoltaic module.
After the terminal equipment acquires the target cable function corresponding to the photovoltaic module matrix, in order to determine the partition result and the wiring sequence of the photovoltaic module corresponding to the condition that the total cost of the cable for wiring is the lowest, parameter optimization is carried out on the target cable function through a genetic algorithm on the basis of a cable cost minimization principle.
Specifically, for example, the input of the optimization objective function f (X) is the position parameter X ═ X of the photovoltaic module 1 ,X 2 ,…,X i ,…,X n And f, (X) obtaining the partitioning result of each partitioning point set and the wiring sequence of the photovoltaic module when the optimization target is f (X) is the minimum value.
From this, it can be seen that the TSP optimization problem of the Genetic Algorithm (GA) can be used to solve.
Specifically, for example, when solving using the GA _ TSP function, the parameters are set as follows:
the objective function is set as: f (X); the number of the populations is set to 100; the genetic iteration times are set to be 200, genetic algorithm solving is carried out based on the above settings, and finally the optimal result of the connection mode of the photovoltaic module partitions and the photovoltaic modules is obtained. The optimized minimum objective function is the minimum cable usage in the photovoltaic module matrix, and the corresponding partitioning result is as follows:
D best ={D 1 best ,D 2 best ,…,D i best ,…,D m best }
further, before the step S10, "obtaining a photovoltaic module set by initially partitioning the photovoltaic modules based on the position parameters of the photovoltaic modules in the preset photovoltaic module square matrix", the method further includes:
and step S40, deriving the position parameters of all the photovoltaic modules in the preset module square matrix from preset drawing software.
Before the terminal equipment partitions the photovoltaic module based on the position parameters of the photovoltaic module in the photovoltaic module matrix, the position parameters of the photovoltaic module in the photovoltaic module matrix are required to be obtained in advance from a CAD drawing or a data file derived from other software.
In this embodiment, after the terminal device performs parameter optimization on the target cable function to obtain the optimal partition of the photovoltaic module, the terminal device further performs area division of the photovoltaic module and connection of the photovoltaic module in the area according to the optimal partition, so that the total cost of cables for wiring is the lowest. Terminal equipment can adopt the capacity of collection flow box or group string dc-to-ac converter to carry out the subregion to all photovoltaic module in the photovoltaic module square matrix. And determining the Manhattan distance between adjacent photovoltaic modules according to the position parameters of each photovoltaic module in the photovoltaic module set, and determining the cable function corresponding to the photovoltaic module set according to the Manhattan distance. In order to partition all photovoltaic modules of the photovoltaic module square matrix, accumulating the cable functions corresponding to all the photovoltaic module sets to obtain a target cable function corresponding to the photovoltaic module square matrix. After the terminal equipment acquires the target cable function corresponding to the photovoltaic module matrix, in order to determine the partition result and the wiring sequence of the photovoltaic module corresponding to the condition that the total cost of the cable for wiring is the lowest, parameter optimization is carried out on the target cable function through a genetic algorithm on the basis of a cable cost minimization principle.
In the invention, after each photovoltaic module in the photovoltaic module matrix is initially partitioned to obtain a photovoltaic module set, and further, cable functions of each photovoltaic module set are subjected to target cable functions of the photovoltaic module matrix, in order to minimize the wiring cost, the target cable functions are subjected to parameter optimization through a genetic algorithm to obtain the optimal partition of each photovoltaic module in the photovoltaic module matrix, and the photovoltaic modules of each sub-area are sequentially connected according to the optimal partition, so that the purpose of minimizing the consumption of the whole simulation cable and reducing the cable cost of a station is achieved.
