In the step, the first component arrangement scheme is a basic scheme constructed on the basis of the photovoltaic power station, and the first component arrangement scheme starts to arrange components by taking the north-most side of the photovoltaic power station as the starting point, and does not need to consider the length of the north-south shade generated by the north-most side height of the first component arrangement scheme.
For example, nine first component arrangement schemes are constructed by taking the north-most side of the photovoltaic power station as a starting position, wherein the nine first component arrangement schemes are respectively a base scheme of one vertical row, one horizontal row, two vertical rows, one horizontal row, three vertical rows, one horizontal row, four vertical rows, one horizontal row and five vertical rows.

The first component arrangement schemes are in one-to-one correspondence with the standard component arrangement schemes, and the first component arrangement schemes represent component arrangement schemes taking the north side of the photovoltaic power station as the starting point.
In actual execution, a plurality of standard component arrangement schemes are put into a standard scheme set, one element in the standard scheme set represents one standard component arrangement scheme, each element in the standard scheme set is sequentially extracted, and a first component arrangement scheme corresponding to each element is generated.
For example, nine standard component arrangement schemes are obtained, which are standard schemes of one vertical row, one horizontal row, two vertical rows, one horizontal row, three vertical rows, one horizontal row, four vertical rows, one horizontal row and five vertical rows respectively.
According to nine standard component arrangement schemes, nine first component arrangement schemes are generated, wherein the nine first component arrangement schemes are respectively a basic scheme of one vertical row, two vertical rows, one horizontal row, three vertical rows, one horizontal row, four vertical rows, one horizontal row and five vertical rows.
The first component arrangement scheme uses the north side of the photovoltaic power station as an initial component arrangement, a standard component arrangement scheme of one vertical row correspondingly generates a first component arrangement scheme of one vertical row from the north side of the photovoltaic power station, and a standard component arrangement scheme of three vertical rows and one horizontal row correspondingly generates a first component arrangement scheme of three vertical rows and one horizontal row from the north side of the photovoltaic power station.
Step 130, determining a first target north-south length and a second target north-south length corresponding to each first component arrangement scheme based on the region size information, the geographic position information and the component arrangement information of the plurality of first component arrangement schemes.
The first target north-south length represents the north-south length required by the first component arrangement scheme, and the second target north-south length represents the remaining north-south length of the photovoltaic power station for the first component arrangement scheme.
The first target north-south length refers to a north-south length required by the first component arrangement scheme when actual component arrangement is performed.

In this embodiment, the first target north-south length includes a north-south length of the first component arrangement when the components are arranged and a north-south length of a shadow generated by a north-most altitude, wherein the north-south length of the shadow generated by the north-most altitude is determined based on geographical location information of the photovoltaic power plant.
In some embodiments, the first target north-south length is a sum of a first north-south length and a north-south shaded length, the component arrangement information of the first component arrangement including the first north-south length and the first north-side height, the north-south shaded length being determined based on the first north-side height and the geographic location information.

The second target north-south length refers to the remaining north-south length of the photovoltaic power station after the actual component arrangement is performed according to the first component arrangement scheme in the photovoltaic power station, and the second target north-south length can be determined according to the component arrangement information of the first component arrangement scheme and the region size information of the photovoltaic power station.
In some embodiments, the second target north-south length is a difference between a power plant north-south length and the first north-south length, the region size information includes the power plant north-south length, and the component arrangement information of the first component arrangement includes the first north-south length.
In this embodiment, the first component arrangement initially constructed by the photovoltaic power station uses the north-most side of the photovoltaic power station as the starting position to perform component arrangement, and when the north-south length calculation is performed, the north-south length of the power station and the difference between the north-south length of the power station and the first north-south length can be directly determined as the second target north-south length corresponding to the first component arrangement without considering the shadow north-south length generated by the north-most side height of the first component arrangement scheme.
And 140, determining a supplementary component arrangement scheme corresponding to each first component arrangement scheme based on the first target north-south length and the second target north-south length.
Wherein the supplemental component arrangement comprises at least one of the plurality of first component arrangements.
In this embodiment, the second target north-south length characterizes a north-south length of the photovoltaic power plant remaining for component arrangement in the first component arrangement scheme, and the first target north-south length characterizes a north-south length required for component arrangement of the first component arrangement scheme in a remaining area of the photovoltaic power plant.
According to the first target north-south length and the second target north-south length, after the first component arrangement scheme is judged to be carried out by taking the north-most side of the photovoltaic power station as the starting position, how many first component arrangement schemes can be arranged in the rest area of the photovoltaic power station, namely, the supplementary component arrangement scheme corresponding to the first component arrangement scheme.
For example, a first component arrangement scheme a, a first component arrangement scheme B, a first component arrangement scheme C, a first component arrangement scheme D, and a first component arrangement scheme E are constructed with the north-most side of the photovoltaic power plant as a starting position.
In this embodiment, according to the second target north-south length a of the first component arrangement scheme a, in combination with the first target north-south length of the first component arrangement scheme a, the first component arrangement scheme B, the first component arrangement scheme C, the first component arrangement scheme D, and the first component arrangement scheme E, it may be determined how many first component arrangement schemes can be arranged in the remaining area of the photovoltaic power plant after the component arrangement is performed in the first component arrangement scheme a.
The component arrangement scheme corresponding to the remaining area of the photovoltaic power station is a supplementary component arrangement scheme, and the supplementary component arrangement scheme can be at least one of a first component arrangement scheme A, a first component arrangement scheme B, a first component arrangement scheme C, a first component arrangement scheme D and a first component arrangement scheme E.
For example, the first component arrangement scheme a is arranged with the north-most side of the photovoltaic power station as a starting position, and at least one of the first component arrangement scheme a, the first component arrangement scheme B, the first component arrangement scheme C, the first component arrangement scheme D, and the first component arrangement scheme E may be arranged in the remaining area of the photovoltaic power station.
And step 150, determining a target component arrangement scheme of the photovoltaic power station based on the plurality of first component arrangement schemes and the supplementary component arrangement scheme corresponding to each first component arrangement scheme.
The first component arrangement scheme and the corresponding supplementary component arrangement scheme are component arrangement schemes aiming at the whole area of the photovoltaic power station.
In this embodiment, by comparing the plurality of first component arrangement schemes and the supplementary component arrangement scheme corresponding to each first component arrangement scheme, it may be possible to determine the information such as the number of component arrangements and the component arrangement area occupation ratio when each first component arrangement scheme and the supplementary component arrangement scheme corresponding to the first component arrangement scheme perform component arrangement, determine the first component arrangement scheme with the optimal arrangement and the supplementary component arrangement scheme corresponding to the first component arrangement scheme, and use the first component arrangement scheme as the target component arrangement scheme of the photovoltaic power station, so as to implement the maximum utilization of the arrangeable area of the photovoltaic power station.
According to the component arrangement method of the photovoltaic power station, the plurality of first component arrangement schemes are constructed, the required north-south length for arrangement is carried out according to the remaining available north-south length of the photovoltaic power station and each first component arrangement scheme, each first component arrangement scheme is supplemented, the first component arrangement scheme with the overall optimal component arrangement and the corresponding supplementary component arrangement scheme are selected, the arrangeable area of the photovoltaic power station is utilized to the greatest extent, the first component arrangement scheme is not limited in particular, and the method has universality.
In some embodiments, step 150, determining a supplemental component arrangement corresponding to each first component arrangement based on the first target north-south length and the second target north-south length may include:
based on the first target north-south length and the second target north-south length, taking the minimum remaining north-south length of the photovoltaic power station for component arrangement as an optimization target, taking the number of arrangement times of a first component arrangement scheme in the supplementary component arrangement scheme as a decision variable, and determining an objective function and constraint conditions;
according to the objective function and the constraint condition, constructing an integer programming model corresponding to the first component arrangement scheme;
And solving the integer programming model to determine a supplementary component arrangement scheme corresponding to the first component arrangement scheme.
In this embodiment, the supplementary component arrangement scheme corresponding to each first component arrangement scheme is solved by constructing an integer programming model corresponding to each first component arrangement scheme.
According to the first target north-south length and the second target north-south length, it can be judged how many first component arrangement schemes can be arranged in the remaining area of the photovoltaic power station after the component arrangement is performed according to the first component arrangement scheme.
