[0002] As a new form of renewable energy, offshore photovoltaic has broad development potential and is one of the important paths to promote energy structure optimization and help achieve the carbon neutralization target. However, offshore photovoltaic fields are exposed to complex marine environments for a long time and are subjected to multiple loads such as wind, waves, and currents. In particular, in areas with frequent typhoons, the wind and wave loads far exceed the normal wind environment, which can easily threaten the structural safety and service life of the photovoltaic system. Therefore, optimizing the offshore photovoltaic breakwater system to effectively reduce the impact of wind and wave loads on photovoltaic panels and supporting structures and improving the durability and economy of the photovoltaic field are key to promoting the large-scale application of offshore photovoltaic in typhoon-prone areas.

[0003] Currently, the optimization of offshore photovoltaic breakwater systems still faces many challenges.

Obviously, the described embodiments are only a part of embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by one of ordinary skill in the art without creative work shall fall within the scope of the present application.

[0062] As shown in the figure, Figure 1 An embodiment of the present application provides an offshore photovoltaic wave protection system optimization method, at least comprising the following steps:

[0063] Step S1, obtaining an initial simulation model of the offshore photovoltaic wave protection system.

[0064] Specifically, obtaining the initial simulation model of the offshore photovoltaic wave protection system is the first step of the wave protection system optimization. This process involves detailed modeling of the overall structure of the offshore photovoltaic field. First, the SACS model of the offshore photovoltaic wave protection system is established to simulate the structural characteristics of the system. The model includes several support columns, support trusses, photovoltaic panels and wave protection panels. In an embodiment, the length of the wave protection panel is equal to the length of the photovoltaic panel, the height of the wave protection panel is set to 2 meters, the number of wave protection panels is 2, and the vertical angle of the wave protection panel is set to 15°. The height of the support column is set to 5 meters, and the structure is sufficient to support the wave protection panel. The distance between the support columns should be an integer multiple of the length of a single photovoltaic panel; the distance between the upper and lower wave protection panels should be less than or equal to the width of the wave protection panel; the support column should be made of hollow corrosion-resistant steel pipe, and the length-diameter ratio of the support column should be less than or equal to 20; the wave protection panels should be made of rectangular corrosion-resistant steel plates, and the thickness of the steel plates should not be less than 20mm; the corrosion-resistant steel plates should be fixed to the support columns by single-bevel groove fusion welding; and the total length of the support column should be greater than the total width of all the wave protection panels, and the support column should be fixed to the offshore photovoltaic support truss by double-bevel groove fusion welding.

[0065] In addition, all parameters can be preset according to the wave height of the target offshore wind farm. The above is only an example. For example, if the maximum wave height of a fifty-year return period is large, the number of wave protection panels can be increased accordingly, and if the maximum wave height is small, the number of wave protection panels can be reduced.

[0066] As shown in the figure, Figure 2 Figure 2 is a structural diagram of an embodiment of the initial simulation model of the offshore photovoltaic wave protection system provided by the present application, which includes support columns 1, support trusses 3, photovoltaic panels 4, and wave protection panels 5.

In this process, the simulation model first performs detailed calculations according to environmental factors such as wind speed, wave height, period, direction, and flow rate of the target sea area to evaluate the wave reduction effect of the breakwater board. By simulating the interaction between waves and breakwater boards, the simulation model considers physical processes such as wave propagation, reflection, and refraction, and calculates the wave reduction effect of the breakwater board under different angles, numbers, and arrangement modes. Finally, by combining wave attenuation efficiency and light energy receiving efficiency, the simulation model provides strong data support for the optimization of the breakwater system to ensure that the breakwater board can protect the photovoltaic system structure while improving the photovoltaic power generation efficiency as much as possible.
