Description

Technical Field

[0001] The present invention relates to the technical field of offshore photovoltaic power generation, and particularly relates to an optimization method, device, electronic device and storage medium for an offshore photovoltaic wave protection system. Background Art

[0002] As an emerging form of renewable energy, offshore photovoltaic has broad development potential and is one of the important paths to promote the optimization of the energy structure and contribute to the carbon neutrality goal. However, offshore photovoltaic farms are long-term exposed to complex marine environments and are affected by multiple loads such as wind, waves and currents. Especially in areas with frequent strong / typhoon occurrences, the wave loads far exceed the normal wind environment, which can easily pose a threat to the structural safety and service life of the photovoltaic system. Therefore, optimizing the offshore photovoltaic wave protection system to effectively reduce the impact of wave loads on photovoltaic panels and support structures and improve the durability and economy of the photovoltaic farm is the key to promoting the large-scale application of offshore photovoltaic in typhoon-prone areas.

[0003] Currently, the optimization of offshore photovoltaic wave protection systems still faces many challenges. Especially the design of the parameters of wave protection plates (such as angles, quantities and arrangement methods) relies on experience and lacks systematic optimization. This may either lead to insufficient wave attenuation efficiency, causing the photovoltaic system to still face relatively high wave impacts, or reduce the light energy reception efficiency due to blocking the photovoltaic panels, affecting the overall power generation benefit, making it difficult for the wave protection system to achieve a balance between structural safety and economy. The above problems seriously restrict the popularization and application of offshore photovoltaic in typhoon-prone areas. Summary of the Invention

[0061] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0062] As Figure 1 shown, an embodiment of the present invention provides an optimization method for an offshore photovoltaic wave protection system, which at least includes the following steps:

[0063] Step S1, obtain the 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 in optimizing the wave protection system. This process involves detailed modeling of the overall structure of the offshore photovoltaic field. First, establish a SACS model of the offshore photovoltaic wave protection system to simulate the structural characteristics of the system. The model includes several support columns, support trusses, photovoltaic panels, and wave protection plates. In one embodiment, the length of the wave protection plate is equal to the length of the photovoltaic panel, the height of the wave protection plate is set to 2 meters, the number is 2, and the vertical angle of the wave protection plate is set to 15°. The height of the support column is set to 5 meters and is sufficient to support the structure of the wave protection plate. 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 plates is less than or equal to the width of the wave protection plate; the support columns are made of hollow anti-corrosion steel pipes, and the length-diameter ratio of the support columns should be less than or equal to 20; the several wave protection plates are rectangular anti-corrosion steel plates, and the thickness of the steel plates should not be less than 20 mm; the anti-corrosion steel plates are all fixed to the support columns by single-sided groove penetration welding; the total length of the support columns needs to be greater than the sum of the widths of all wave protection plates and is fixed to the offshore photovoltaic support truss by double-sided groove penetration welding.

[0065] In addition, all parameters can be preset according to the wave height situation of the target offshore wind farm. The above is only an example. For example, if the maximum wave height once in 50 years is relatively large, the number of wave protection plates can be increased accordingly. If the maximum wave height is relatively small, the number of wave protection plates can be reduced.

[0066] As Figure 2 shown, Figure 2 is a schematic structural diagram of an embodiment of the initial simulation model of the offshore photovoltaic wave protection system provided by the present invention, including: support column 1, support truss 3, photovoltaic panel 4, wave protection plate 5. The wave protection plate 5 is welded to the support column 1 by single-sided groove penetration welding; the support column 1 is welded to the support truss 3 by double-sided groove penetration welding.

[0067] As Figure 3 shown, Figure 3It is another structural schematic diagram of the initial simulation model of the offshore photovoltaic wave protection system provided by the present invention, including: support columns 1, wave protection board angles 2, support trusses 3, photovoltaic panels 4, and wave protection boards 5; the initial simulation model of the wave protection system is composed of several wave protection boards 5 and support columns 1. The number of wave protection board angles 2 and wave protection boards 5 is obtained by calculation. The setting of the wave protection boards 5 plays a role in blocking waves, significantly improving the durability of the photovoltaic panels.

[0068] Step S2: Repeatedly perform the wave protection board parameter optimization operation to optimize the wave protection board parameters in the initial simulation model until the wave load is less than the preset load threshold, and generate the final parameters of the wave protection board.

[0069] As Figure 2 shown, in a preferred embodiment, the wave protection board parameter optimization operation includes:

[0070] Step S2.1: Input the preset environmental load into the current simulation model, so that the current simulation model respectively performs wave blocking analysis on the surface of the wave protection board and shading effect analysis on the photovoltaic panel according to the preset environmental load, and generates the wave attenuation efficiency and the light energy reception efficiency.

[0071] Specifically, after inputting the preset environmental load into the current simulation model, the model performs wave blocking analysis on the surface of the wave protection board and shading effect analysis on the photovoltaic panel according to these load data, and generates the wave attenuation efficiency and the light energy reception efficiency. During this process, the simulation model will first perform detailed calculations based on environmental factors such as wind speed, wave height, period, direction, and flow velocity in the target sea area to evaluate the wave reduction effect of the wave protection board. By simulating the interaction between waves and the wave protection board, the simulation model considers physical processes such as wave propagation, reflection, and refraction, and calculates the wave reduction effect of the wave protection board at different angles, quantities, and arrangements. Finally, by combining the wave attenuation efficiency and the light energy reception efficiency, the simulation model provides strong data support for the optimization of the wave protection system to ensure that the wave protection board can improve the photovoltaic power generation efficiency as much as possible while ensuring the structural safety of the photovoltaic system.

[0072] In addition, in an embodiment, the preset environmental load is extreme environmental loads such as strong / typhoon wave currents and the most unfavorable load combination is performed. These loads consider marine environmental factors such as strong winds and large waves caused by typhoons, and simulate the impact on the wave protection system under extreme marine conditions. In the simulation model, by combining parameters such as the maximum wind speed, wave height, and period, the wave reduction effect of the wave protection board on wind waves is evaluated, and the shading effect of the photovoltaic panel is analyzed. At the same time, long-term environmental factors such as tidal current, marine corrosion, and marine organism attachment are also considered to perform the most unfavorable load combination to ensure that the wave protection system can still maintain stability and safety under extreme conditions, and improve the overall reliability and durability of the photovoltaic system.

[0073] In a preferred embodiment, the current simulation model includes the total area of the photovoltaic panels; the preset environmental load includes the incident wave height;

[0074] Inputting the preset environmental load into the current simulation model so that the current simulation model respectively performs wave blocking analysis on the surface of the wave breakwater and light shading effect analysis of the photovoltaic panels according to the preset environmental load, and generating the wave attenuation efficiency and the light energy reception efficiency, includes:

[0086] Step S2.2: If there is a wave attenuation efficiency or a light energy reception efficiency that does not exceed the corresponding preset threshold, adjust the parameters of the wave breakwater in the current simulation model and update the current simulation model;

[0087] Specifically, in one embodiment, the preset threshold of the wave attenuation efficiency can be 80%; the preset threshold of the light energy reception efficiency can be 95%. It can be flexibly adjusted according to the actual situation. Specifically, the key parameters such as the angle, quantity, and height of the wave baffle can be adjusted to improve its wave blocking ability and reduce the shading effect on the photovoltaic panel.

[0088] Step S2.3: If both the wave attenuation efficiency and the light energy reception efficiency exceed the corresponding preset thresholds, input the environmental load into the current simulation model, so that the current simulation model performs wave force analysis according to the preset environmental load to generate wave loads; determine whether the wave loads are less than the preset load threshold. If so, use the parameters of the wave baffle in the current simulation model as the final parameters of the wave baffle; if not, adjust the parameters of the wave baffle in the current simulation model and update the current simulation model.

[0089] In a preferred embodiment, the current simulation model includes the parameters of the wave baffle and the angle between the wave baffle and the vertical direction; the preset environmental load includes seawater density.

[0090] The step of inputting the environmental load into the current simulation model so that the current simulation model performs wave force analysis according to the preset environmental load to generate wave loads includes:

[0091] Calculate and generate the effective wave-facing area of the wave baffle according to the parameters of the wave baffle and the angle between the wave baffle and the vertical direction.

[0092] Input the preset environmental load into the current offshore photovoltaic wave protection simulation model so that the offshore photovoltaic wave protection simulation model performs wave force analysis to generate the horizontal velocity of the wave water particles and the horizontal acceleration of the wave water particles.

[0096] In a preferred embodiment, the effective wave-facing area of the wave baffle is calculated by the following formula:

[0097] A = LWcosα

[0098] Where, W is the width of a single wave baffle; α is the angle between the wave baffle and the vertical direction.

[0099] In a preferred embodiment, the horizontal drag force is calculated by the following formula:

[0101] where f D (t) is the horizontal drag force at time t; n is the number of wave breakers; ρ ω is the seawater density; C D is the velocity force coefficient; L is the length of a single wave breaker; u(t) is the horizontal velocity of the wave water particle at time t; |u(t)| is the absolute value of the horizontal velocity of the wave water particle at time t.

[0102] In a preferred embodiment, the horizontal inertial force is calculated by the following formula:

[0103] f I (t) = nρ ω C M Aa(t)

[0104] where f I (t) is the horizontal inertial force at time t; n is the number of wave breakers; ρ ω is the seawater density; C M is the inertial force coefficient; A is the effective wave-facing area of the wave breaker; a(t) is the horizontal acceleration of the wave water particle at time t.

[0105] Specifically, the wave load is calculated by the following formula:

[0108] Step S3: Determine the angle, number, and height of the target wave breaker in the offshore photovoltaic wave protection system according to the final parameters of the wave breaker; set the wave breakers in the offshore photovoltaic wave protection system according to the angle, number, and height of the target wave breaker;

[0109] It should be noted that according to the optimized and adjusted parameters of the wave breaker, the angle, number, and height of the target wave breaker in the offshore photovoltaic wave protection system are finally determined to ensure that while meeting the requirements of wave attenuation efficiency, the impact on the light energy reception of the photovoltaic panel is minimized. Subsequently, according to the determined parameters of the target wave breaker, actual layout is carried out in the offshore photovoltaic wave protection system, and the installation position, fixing method, and structural support scheme of the wave breaker are reasonably set to ensure the stability and long-term durability of the wave breaker. At the same time, combined with the engineering environmental conditions, the material selection, corrosion resistance, and maintenance strategy of the wave breaker are optimized to enhance the overall wave resistance and operation reliability of the system, so as to ensure the efficient operation of the offshore photovoltaic wave protection system in a complex marine environment.
