[0043] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0045] Figure 1 1 is a flow chart of a method for determining a photovoltaic module string line arrangement provided by an embodiment of the present invention. This embodiment is applicable to the case where a photovoltaic module string line arrangement is determined. The method can be executed by a photovoltaic module string line arrangement determination device. Figure 1 As shown, the method includes:

[0046] S110 , dividing the photovoltaic components into multiple clusters according to the parameters of the inverter, and allocating each cluster of components to a corresponding inverter.

[0047] Specifically, all photovoltaic components are globally scanned, and the photovoltaic components are divided according to the parameters of the inverter, and the photovoltaic components are divided into multiple clusters of components. For example, the photovoltaic components are divided according to the number of inverters, so that the number of clusters of photovoltaic components is the same as the number of inverters, which is convenient for allocating each cluster of components to the corresponding inverter. When allocating each cluster of components to the corresponding inverter, the allocation can be made according to the parameters of the inverter and the type of photovoltaic components, for example, according to the power adaptation range of the inverter and the power of each cluster of components, so that each cluster of components can be adapted to the corresponding inverter, thereby realizing coarse-grained component resource allocation for the inverter.

[0048] Exemplarily, the number of inverters is, for example, p, where p is a positive integer greater than or equal to 1, and the p inverters are [W1, W2, ... Wp]. After the photovoltaic components are divided according to the parameters of the inverter, p cluster components are obtained, and the p cluster components are [N1, N2, ... Np]. After each cluster component is allocated to the corresponding inverter, the allocation result is, for example, {[W1, N1], [W2, N2], ... [Wp, Np]}.

[0049] S120, in each cluster of components, iteratively search the neighborhood of each photovoltaic component to obtain multiple connected region sequences.

[0050] Specifically, in each cluster of components, the neighborhood of each photovoltaic component is iteratively searched to obtain multiple strings, which realizes the division of each cluster of components into strings. When iteratively searching the neighborhood of photovoltaic components, you can search horizontally or vertically, and you can search the two-neighborhood, four-neighborhood, or eight-neighborhood of photovoltaic components, so each cluster of components will have multiple string division methods, and each division method can obtain a connected area sequence, and a connected area sequence represents a string line arrangement method. Therefore, after iterative search, multiple connected area sequences can be obtained, which realizes fine-grained component resource division for each inverter.

[0051] Exemplarily, in each cluster component {[W1, N1], [W2, N2], ... [Wp, Np]}, the neighborhood of each photovoltaic component is iteratively searched to obtain multiple connected region sequences {[Nx1, Nx2, ..., Nxs]1, ..., [Nx1, Nx2, ..., Nxs]p}. Wherein, s represents the number of connected region sequences, s is a positive integer greater than or equal to 1, Nx1 represents the first connected region sequence in each cluster component, Nx2 represents the second connected region sequence in each cluster component, ..., Nxs represents the sth connected region sequence in each cluster component.

[0052] S130, calculating the distances between the starting point and the end point in each connected area sequence and the corresponding inverter, and determining the string arrangement of each cluster of components and the inverter according to the connected area sequence corresponding to the smallest distance among all distances.

[0053] Specifically, there are multiple strings in each connected area sequence. In each connected area sequence, the first distance from the photovoltaic component at the starting point of all strings to the corresponding inverter and the second distance from the photovoltaic component at the end point to the corresponding inverter are added together to obtain the distance between the photovoltaic component at the starting point and the photovoltaic component at the end point and the corresponding inverter in each connected area sequence. All distances are compared, and the connected area sequence corresponding to the smallest distance among all distances is taken as the optimal sequence. By determining the string arrangement of photovoltaic components according to the optimal sequence, a better string arrangement can be achieved, which is conducive to reducing the cable length, reducing the series connection time of photovoltaic components, and reducing the string cost.

[0054] The technical solution of this embodiment is to divide the photovoltaic components into multiple clusters according to the parameters of the inverter, and allocate each cluster of components to the corresponding inverter, so as to realize the coarse-grained component resource allocation for the inverter. In each cluster of components, the neighborhood of each photovoltaic component is iteratively searched to obtain multiple strings, so as to realize the string division of each cluster of components. When iteratively searching the neighborhood of the photovoltaic component, the search can be performed horizontally or vertically, and the two neighborhoods, four neighborhoods or eight neighborhoods of the photovoltaic component can be searched, so each cluster of components will have multiple string division methods; each division method can obtain a connected area sequence, and a connected area sequence represents a string line arrangement method, so multiple connected area sequences can be obtained, so as to realize the fine-grained component resource division for each inverter. There are multiple strings in each connected area sequence. In each connected area sequence, the first distance from the photovoltaic component at the starting point of all strings to the corresponding inverter and the second distance from the photovoltaic component at the end point to the corresponding inverter are added, so as to obtain the distance between the photovoltaic component at the starting point and the photovoltaic component at the end point and the corresponding inverter in each connected area sequence. Compare all the distances, take the connected area sequence corresponding to the smallest distance among all the distances as the optimal sequence, and determine the string line arrangement of the photovoltaic module according to the optimal sequence, so as to achieve a better string line arrangement. It is beneficial to reduce the cable length, reduce the string line connection time, and reduce the string line cost. The technical solution of this embodiment solves the problem that the string line arrangement in the component arrangement is carried out in a strange-shaped square array, which causes the string line arrangement to be time-consuming and labor-intensive, and the final string line arrangement is not optimal. The effect of achieving a better string line arrangement is achieved, which is beneficial to reduce the cable length, reduce the string line connection time, and reduce the string line cost.

[0055] Figure 2 is a flowchart of another method for determining the arrangement of photovoltaic assembly strings provided by an embodiment of the present invention. Optionally, refer to Figure 2 The photovoltaic module string line arrangement determination method includes:

[0056] S210, dividing the photovoltaic components into multiple clusters according to the number of inverters, with the center of the photovoltaic component array as the center and a preset distance as the radius as the boundary, and allocating each cluster of components to a corresponding inverter.

[0057] Specifically, the photovoltaic components are divided into a circle with the center of the photovoltaic component array as the center and the preset distance as the radius as the boundary. The preset distance can be determined according to actual conditions and can be flexibly changed according to the number of inverters, so that the number of clusters of photovoltaic components obtained is the same as the number of inverters, which is convenient for allocating each cluster of components to the corresponding inverter.

[0058] Furthermore, by dividing the photovoltaic components into a circle with the center of the photovoltaic component array as the center and a preset distance as the radius as the boundary, the distance between the photovoltaic components in each cluster of components can be made smaller, which facilitates the connection between the photovoltaic components; and facilitates the connection between the photovoltaic components and the corresponding inverter, which is beneficial to further reduce the length of the electrical terminal connection in the string arrangement and reduce the cable cost.

[0059] Optionally, allocating each cluster of components to a corresponding inverter includes:

[0060] Each cluster of components is allocated to the corresponding inverter according to the power adaptation range of the inverter.

[0061] Specifically, when allocating each cluster of components to the corresponding inverter, the allocation can be made according to the parameters of the inverter and the type of photovoltaic components. For example, the allocation can be made according to the power adaptation range of the inverter and the power of each cluster of components, so that each cluster of components can be adapted to the corresponding inverter, which is conducive to the normal operation of the inverter.

[0062] S220, in each cluster of components, iteratively search the neighborhood of each photovoltaic component to obtain multiple strings, and obtain multiple connected area sequences within a preset string range.

[0063] The preset string range is the number of photovoltaic modules in the string that can be connected to each inverter. The value of the preset string range can be determined according to parameters such as the capacity of the inverter, and the preset string range of each inverter can be different.

[0064] Specifically, in each cluster of components, the neighborhood of each photovoltaic component is iteratively searched until the number of photovoltaic components meets the preset string range, and a string is obtained. Then, the neighborhood of the remaining photovoltaic components is iteratively searched until the number of photovoltaic components meets the preset string range, and another string can be obtained. This is repeated until all photovoltaic components in each cluster of components are traversed, and multiple strings can be obtained. Each cluster of components can have multiple ways of iterative search, and there can be multiple ways of connecting strings, so each cluster of components can obtain multiple connected area sequences within the preset string range.

[0065] S230, calculating the distances between the starting point and the end point in each connected area sequence and the corresponding inverter, and determining the string arrangement of each cluster of components and the inverter according to the connected area sequence corresponding to the smallest distance among all distances.

[0066] Optionally, calculating the distances between the starting point and the end point in each connected region sequence and the corresponding inverter includes:

[0067] Step a: determining the first center coordinates of the photovoltaic assembly at the starting point and the second center coordinates of the photovoltaic assembly at the end point in each connected region sequence.

[0068] Specifically, in each connected region sequence, the first center coordinates of the photovoltaic module at the starting point and the second center coordinates of the photovoltaic module at the end point in each string are determined. The establishment of the coordinate system can be determined according to actual conditions, for example, according to the distribution of the photovoltaic modules, which is not limited here.

[0069] Step b: calculating the distances between the first center coordinate and the second center coordinate and the inverter.

[0070] Specifically, in each connected area sequence, the sum of the distance between the first center coordinate of all strings and the inverter and the distance between the second center coordinate and the inverter is calculated to obtain the distance between the photovoltaic components at the starting point and the photovoltaic components at the end point and the corresponding inverter in each connected area sequence. All distances are compared, and the connected area sequence corresponding to the smallest distance among all distances is taken as the optimal sequence. The string arrangement of the photovoltaic components is determined according to the optimal sequence, so that a better string arrangement can be achieved, which is conducive to reducing the cable length and reducing the string cost.

[0071] The technical solution of this embodiment divides the photovoltaic components by dividing the circle with the center of the photovoltaic component array as the center and the preset distance as the radius as the boundary, so that the number of clusters of photovoltaic components obtained is the same as the number of inverters, which is convenient for allocating each cluster of components to the corresponding inverter; and the distance between photovoltaic components in each cluster of components can be made smaller, which is convenient for connecting photovoltaic components and connecting photovoltaic components with corresponding inverters, which is conducive to further reducing the length of electrical terminal connections in string arrangement and reducing cable costs. In each cluster of components, iteratively searching the neighborhood of each photovoltaic component can obtain multiple strings. There can be multiple ways to iteratively search for each cluster of components, and there can be multiple ways to connect strings, so each cluster of components can obtain multiple connected area sequences within the preset string range. Calculate the distance between the photovoltaic component at the starting point and the photovoltaic component at the end point and the corresponding inverter in each connected area sequence. By comparing all distances, the optimal connected area sequence can be determined, thereby determining a better photovoltaic component string arrangement method.

[0072] Figure 3is a flowchart of another method for determining the arrangement of photovoltaic assembly strings provided by an embodiment of the present invention. Optionally, refer to Figure 3 The photovoltaic module string line arrangement determination method includes:

[0073] S310, dividing the photovoltaic components into multiple clusters according to the number of inverters, with the center of the photovoltaic component array as the center and a preset distance as the radius as the boundary, and allocating each cluster of components to a corresponding inverter.

[0074] S320: In each cluster of components, select a photovoltaic component as the current center.

[0075] Specifically, in each cluster of components, one photovoltaic component can be selected as the current center. For example, the center of all components can be selected as the current center, or the center of a certain part of all photovoltaic components can be selected as the current center. The specific selection can be determined according to actual conditions, and this embodiment does not limit it.

[0076] S330: Determine the photovoltaic components corresponding to the current neighborhood of the current center.

[0077] Specifically, by searching and determining the current neighborhood of the current center, the photovoltaic components corresponding to the current neighborhood can be determined, and the photovoltaic components closer to the current center can be found. By searching the neighborhood, the distance between the photovoltaic components in the formed string is closer, which is conducive to reducing the cable length of the string line arrangement.

[0078] Optionally, determining a photovoltaic component corresponding to a current neighborhood of a current center includes:

[0079] The photovoltaic components corresponding to the current two-neighborhood, four-neighborhood or eight-neighborhood of the current center are determined.

[0080] Specifically, the current neighborhood of the current center is determined by searching, for example, the current second neighborhood, the fourth neighborhood, or the eighth neighborhood of the current center is searched. Figure 4 is a schematic diagram of the structure of the eight neighborhoods of any component center provided by an embodiment of the present invention, such as Figure 4 As shown, the eight neighborhoods of the current center A0 are A1, A2, A3, A4, A5, A6, A7 and A8. By searching the eight neighborhoods of the current center, eight photovoltaic modules that are closer to the current center can be obtained. Exemplarily, when the number of photovoltaic modules is small, for example, the two neighborhoods or four neighborhoods of the current center can be searched to determine the string; when the number of photovoltaic modules is large, for example, the eight neighborhoods of the current center can be searched. The specific determination can be made according to the actual situation and is not limited here.

[0081] S340, taking the photovoltaic component corresponding to the current neighborhood as the next center, determining the photovoltaic component corresponding to the next neighborhood of the next center, until the number of photovoltaic components meets the preset string range, thereby obtaining a string.

[0082] Specifically, the photovoltaic component corresponding to the current neighborhood is taken as the next center, and the neighborhood search is continued to determine the photovoltaic component corresponding to the next neighborhood of the next center. By continuously performing the neighborhood search until the number of photovoltaic components meets the preset string range, a string is obtained.

[0083] S350, determining whether all photovoltaic modules in each cluster of modules have been traversed, if so, executing step S360, if not, executing step S370.

[0084] Specifically, if all photovoltaic components in the cluster component have been traversed, multiple strings can be obtained, and multiple connected area sequences within the preset string range can be obtained. If there are photovoltaic components that have not been traversed in the cluster component, it is necessary to continue the neighborhood search until all photovoltaic components are traversed.

[0085] S360, obtaining a plurality of strings, and obtaining a plurality of connected area sequences within a preset string range.

[0086] S370, selecting a photovoltaic module from the remaining photovoltaic modules as the current center, and returning to step S330.

[0087] Specifically, a photovoltaic component is selected from the remaining photovoltaic components as the current center. For example, a photovoltaic component located in the middle of the remaining photovoltaic components can be selected, or other photovoltaic components can be selected from the remaining photovoltaic components as the current center, so as to continue the neighborhood search until all photovoltaic components are traversed.

[0088] S380, calculating the distances between the starting point and the end point in each connected area sequence and the corresponding inverter, and determining the string arrangement of each cluster of components and the inverter according to the connected area sequence corresponding to the smallest distance among all distances.

[0089] The technical solution of this embodiment is to select a photovoltaic component as the current center in each cluster of components, determine the photovoltaic component corresponding to the current neighborhood of the current center, and determine the photovoltaic component corresponding to the current neighborhood, so as to find the photovoltaic component closer to the current center; by searching the neighborhood, the distance between the photovoltaic components in the formed string is closer, which is beneficial to reducing the cable length of the string arrangement; take the photovoltaic component corresponding to the current neighborhood as the next center, determine the photovoltaic component corresponding to the next neighborhood of the next center, until the number of photovoltaic components meets the preset string range, a string can be obtained; select a photovoltaic component as the current center among the remaining photovoltaic components, continue to iterate the search, until all photovoltaic components are traversed, multiple strings can be obtained, and multiple connected area sequences of the preset string range can be obtained.
