Description

A method, apparatus, electronic device and storage medium for optimizing a marine photovoltaic breakwater system. Technical Field

[0001] This invention relates to the field of marine photovoltaic power generation technology, specifically to an optimization method, device, electronic equipment, and storage medium for a marine photovoltaic breakwater system. Background Technology

[0002] Offshore photovoltaic (PV) systems, as an emerging form of renewable energy, possess vast development potential and are a crucial pathway to optimizing the energy structure and contributing to carbon neutrality goals. However, offshore PV farms are constantly exposed to the complex marine environment, subjected to multiple loads from wind, waves, and currents. Especially in areas prone to strong typhoons, the wind and wave loads far exceed those of normal wind conditions, easily threatening the structural safety and lifespan of the PV system. Therefore, optimizing offshore PV breakwater systems to effectively reduce the impact of wind and wave loads on the PV panels and supporting structures, and improving the durability and economic viability of PV farms, is key to promoting the large-scale application of offshore PV in typhoon-prone areas.

[0003] Currently, optimizing offshore photovoltaic (PV) breakwater systems still faces numerous challenges. In particular, the design of breakwater parameters (such as angle, quantity, and arrangement) relies heavily on experience and lacks systematic optimization. This can lead to insufficient wave attenuation efficiency, leaving the PV system still vulnerable to high wave impacts, or it can reduce light reception efficiency by obstructing the PV panels, affecting overall power generation efficiency. Consequently, it is difficult to achieve a balance between structural safety and economic efficiency in breakwater systems. These problems severely restrict the widespread application of offshore PV systems in typhoon-prone areas. Summary of the Invention

[0056] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0057] As shown in Figure 1, an embodiment of the present invention provides an optimization method for a marine photovoltaic breakwater system, which includes at least the following steps:

[0058] Step S1: Obtain the initial simulation model of the marine photovoltaic breakwater system.

[0059] Specifically, obtaining an initial simulation model of the marine photovoltaic breakwater system is the first step in optimizing the breakwater system. This process involves detailed modeling of the overall structure of the marine photovoltaic field. First, a SACS model of the marine photovoltaic breakwater system is established to simulate the structural characteristics of the system. The model includes several supporting columns, supporting trusses, photovoltaic panels, and breakwaters. In one embodiment, the length of the breakwater is equal to the length of the photovoltaic panels, the height of the breakwater is set to 2 meters, there are 2 breakwaters, and the angle between the breakwater and the vertical direction is set to 15°. The height of the supporting columns is set to 5 meters, sufficient to support the structure of the breakwater. The spacing between the supporting columns should be an integer multiple of the length of a single photovoltaic panel; the distance between the upper and lower baffles should be less than or equal to the width of the baffles; the supporting columns should be made of hollow anti-corrosion steel pipes, and the length-to-diameter ratio of the supporting columns should be less than or equal to 20; the baffles should be rectangular anti-corrosion steel plates, and the thickness of the steel plates should not be less than 20mm; the anti-corrosion steel plates should all be fixed to the supporting columns by single-sided bevel penetration welding; the total length of the supporting columns should be greater than the sum of the widths of all the baffles, and they should be fixed to the offshore photovoltaic support truss by double-sided bevel penetration welding.

[0060] Furthermore, all parameters can be preset according to the wave height conditions of the target offshore wind farm; the above is just one example. For instance, if the maximum wave height during a 50-year return period is large, the number of breakwaters can be increased accordingly; if the maximum wave height is small, the number of breakwaters can be reduced.

[0061] As shown in Figure 2, Figure 2 is a structural schematic diagram of an embodiment of the initial simulation model of the marine photovoltaic breakwater system provided by the present invention, including: support column 1, support truss 3, photovoltaic panel 4, and breakwater plate 5. The breakwater plate 5 is welded to the support column 1 using single-sided bevel penetration welding; the support column 1 is welded to the support truss 3 using double-sided bevel penetration welding.

[0062] As shown in Figure 3, Figure 3 is a schematic diagram of another embodiment of the initial simulation model of the marine photovoltaic breakwater system provided by the present invention, including: supporting columns 1, an angle 2 between the breakwater and the vertical direction, supporting trusses 3, photovoltaic panels 4, and breakwaters 5; the initial simulation model of the breakwater system consists of several breakwaters 5 and supporting columns 1. The angle 2 between the breakwater and the vertical direction and the number of breakwaters 5 are calculated. The breakwaters 5 serve to block waves and significantly improve the durability of the photovoltaic panels.

[0063] Step S2: Repeat the breakwater parameter optimization operation to optimize the breakwater parameters in the initial simulation model until the wave load is less than the preset load threshold, and generate the final breakwater parameters; wherein, the breakwater parameters include the angle, number and height of the breakwater.

[0064] As shown in Figure 2, in a preferred embodiment, the baffle plate parameter optimization operation includes:

[0065] Step S2.1: Input the preset environmental load into the current simulation model so that the current simulation model can perform wave-blocking analysis of the wave shield surface and shading effect analysis of the photovoltaic panel according to the preset environmental load, and generate wave attenuation efficiency and light energy reception efficiency.

[0066] Specifically, after inputting the preset environmental loads into the current simulation model, the model performs wave-blocking analysis on the breakwater surface and shading effect analysis on the photovoltaic panels based on these load data, generating wave attenuation efficiency and light energy reception efficiency. In this process, the simulation model first performs detailed calculations based on environmental factors such as wind speed, wave height, period, direction, and current velocity in the target sea area to evaluate the wave-reduction effect of the breakwater. By simulating the interaction between waves and the breakwater, the simulation model considers physical processes such as wave propagation, reflection, and refraction, and calculates the wave-reduction effect of the breakwater under different angles, numbers, and arrangements. Finally, by combining wave attenuation efficiency and light energy reception efficiency, the simulation model provides strong data support for optimizing the breakwater system, ensuring that the breakwater maximizes photovoltaic power generation efficiency while ensuring the structural safety of the photovoltaic system.

[0067] Furthermore, in one embodiment, the preset environmental loads are extreme environmental loads such as strong / typhoon waves and currents, combined with the most unfavorable load combination. These loads take into account marine environmental factors such as strong winds and large waves caused by typhoons, simulating the impact of extreme marine conditions on the breakwater system. In the simulation model, the wave-reduction effect of the breakwater on wind and waves is evaluated by combining parameters such as maximum wind speed, wave height, and period, and the shading effect of the photovoltaic panel is analyzed. At the same time, long-term environmental factors such as tidal currents, marine corrosion, and marine organism attachment are also considered, and the most unfavorable load combination is performed to ensure that the breakwater system can maintain stability and safety under extreme conditions, thereby improving the overall reliability and durability of the photovoltaic system.

[0068] In a preferred embodiment, the preset parameters in the current simulation model include the total area of ​​the photovoltaic panels; the preset environmental load includes the incident wave height.

[0069] The process involves inputting a preset environmental load into the current simulation model, enabling the model to perform wave-blocking analysis on the surface of the breakwater and shading effect analysis on the photovoltaic panel based on the preset environmental load, thereby generating wave attenuation efficiency and light energy reception efficiency. This includes:

[0070] The preset environmental load is input into the current marine photovoltaic breakwater simulation model so that the marine photovoltaic breakwater simulation model can perform wave blocking analysis on the surface of the breakwater and generate the wave height of the transmitted wave.

[0071] The wave attenuation efficiency is calculated based on the incident wave height and the transmitted wave height.

[0078] Where, η solar For light energy receiving efficiency; I received The effective light-receiving area of ​​the photovoltaic panel; I max This refers to the total area of ​​the photovoltaic panels;

[0079] Step S2.2: If the wave attenuation efficiency or light energy receiving efficiency does not exceed the preset corresponding threshold, adjust the wave shield parameters in the current simulation model and update the current simulation model.

[0080] Specifically, in one embodiment, the preset threshold for wave attenuation efficiency can be 80%; the preset threshold for light energy reception efficiency can be 95%. These can be flexibly adjusted according to actual conditions. Specifically, the wave-blocking capability of the wave-shielding plates can be improved and the shading effect on the photovoltaic panels reduced by adjusting key parameters such as the angle, number, and height of the wave-shielding plates.

[0081] Step S2.3: If both the wave attenuation efficiency and the light energy receiving efficiency exceed the preset corresponding thresholds, input the environmental load into the current simulation model so that the current simulation model can perform wave force analysis based on the preset environmental load and generate wave load; determine whether the wave load is less than the preset load threshold. If yes, use the wave deflector parameters in the current simulation model as the final wave deflector parameters; if no, adjust the wave deflector parameters in the current simulation model and update the current simulation model.

[0082] In a preferred embodiment, the breakwater parameters in the current simulation model include the angle between the breakwater and the vertical direction; the preset environmental load includes seawater density;

[0083] The step of inputting the environmental load into the current simulation model, so that the current simulation model performs wave force analysis based on the preset environmental load and generates wave loads, includes:

[0084] The effective wave-facing area of ​​the wave-breaking plate is calculated and generated using the simulation model based on the parameters of the wave-breaking plate and the angle between the wave-breaking plate and the vertical direction.

[0085] The preset environmental load is input into the current marine photovoltaic breakwater simulation model so that the marine photovoltaic breakwater simulation model can perform wave force analysis and generate the horizontal velocity and horizontal acceleration of wave water particles.

[0086] The simulation model calculates and generates horizontal drag force based on the horizontal velocity of wave particles, the parameters of the breakwater, and the density of seawater.

[0087] The simulation model calculates and generates horizontal inertial force based on the horizontal acceleration of wave particles, the parameters of the breakwater, the seawater density, and the effective wave-facing area of ​​the breakwater.

[0088] The simulation model is used to calculate the sum of horizontal drag force and horizontal inertial force to generate wave load.

[0089] In a preferred embodiment, the effective wave-facing area of ​​the breakwater is calculated using the following formula: A = LW cos α

[0090] Where L is the length of a single wave deflector; W is the width of a single wave deflector; and α is the angle between the wave deflector and the vertical direction.

[0091] In a preferred embodiment, the horizontal drag force is calculated using the following formula:

[0092] Among them, f D (t) represents the horizontal drag force at time t; n represents the number of wave deflectors; ρω C is the density of seawater. D denoted as the velocity force coefficient; L is the length of a single wave-breaking plate; 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.

[0093] In a preferred embodiment, the horizontal inertial force is calculated using the following formula: f I (t)=nρ ω C M Aa(t)

[0094] Among them, f I (t) represents the horizontal inertial force at time t; n represents the number of wave deflectors; ρ ω C is the density of seawater. M is the inertial force coefficient; A is the effective wave-facing area of ​​the breakwater; a(t) is the horizontal acceleration of the wave water particles at time t.

[0095] Specifically, wave loads are calculated using the following formula:

[0096] Where f(t) represents the wave load.

[0097] Step S3: Based on the final breakwater parameters, set the breakwater for the marine photovoltaic breakwater system;

[0098] It should be noted that, based on the optimized and adjusted breakwater parameters, the angle, number, and height of the target breakwaters in the marine photovoltaic breakwater system were ultimately determined to ensure that they meet wave attenuation efficiency requirements while minimizing the impact on the photovoltaic panels' light reception. Subsequently, according to the determined target breakwater parameters, the breakwaters were actually deployed in the marine photovoltaic breakwater system, and the installation positions, fixing methods, and structural support schemes of the breakwaters were rationally set to ensure their stability and long-term durability. Simultaneously, considering the engineering environmental conditions, the material selection, corrosion resistance, and maintenance strategies of the breakwaters were optimized to improve the overall wind and wave resistance and operational reliability of the system, thereby ensuring the efficient operation of the marine photovoltaic breakwater system in complex marine environments.

[0100] As shown in Figure 4, an embodiment of the present invention provides an optimization device for a marine photovoltaic breakwater system, including: a simulation model acquisition module, a breakwater parameter confirmation module, a breakwater parameter optimization module, and a breakwater system setting module;

[0101] The simulation model acquisition module is used to acquire the initial simulation model of the marine photovoltaic breakwater system;

If the wave attenuation efficiency or light energy receiving efficiency does not exceed the preset corresponding threshold, the breakwater parameters in the current simulation model are adjusted, and the current simulation model is updated. If both the wave attenuation efficiency and light energy receiving efficiency exceed the preset corresponding threshold, the environmental load is input into the current simulation model, so that the current simulation model can perform wave force analysis according to the preset environmental load and generate wave load. It is then determined whether the wave load is less than the preset load threshold. If yes, the breakwater parameters in the current simulation model are used as the final breakwater parameters; otherwise, the breakwater parameters in the current simulation model are adjusted, and the current simulation model is updated.
