[0051] Please refer to Figure 1 , Figure 1 Schematic flowchart of a method for estimating the power generation of a floating photovoltaic system provided by the embodiments of the present invention. This method for estimating the power generation of a floating photovoltaic system is based on the optimal working conditions, quantitatively analyzes the influence of waves with different periods or wave heights on the swing angle of the floating body of the floating photovoltaic system, and overcomes the limitation of only exploring the technology of onshore photovoltaic systems in the past.

[0052] Specifically, obtain the design specifications of the photovoltaic power station and the site coordinates, determine the installation inclination range and basic parameters; calculate the arrangement spacing and power generation at different installation inclinations, find the maximum power generation, and determine the optimal installation inclination and arrangement spacing; according to the optimal installation inclination and arrangement spacing, use photovoltaic system design software to calculate the power generation at different installation heights, find the highest power generation and determine the optimal installation height to obtain the optimal arrangement condition; based on the optimal arrangement condition, construct a floating body simulation model to analyze the influence of waves on the swing angle of the floating body; calculate the total radiation energy received by the offshore photovoltaic system within the regular wave period and compare it with the radiation energy of the ground system to obtain the total radiation energy ratio; through simulation calculations of the power generation at different installation inclinations, arrangement spacings and installation heights, traverse and optimize various parameters; in the photovoltaic system design software, optimize the power generation by adjusting various parameters such as inclination, arrangement spacing and height; finally, accurately estimate the power generation of the offshore floating photovoltaic system by calculating the optimal installation inclination, arrangement spacing and installation height.

[0053] Figure 1 is a schematic flow chart of a method for estimating the power generation of a floating photovoltaic system provided by an embodiment of the present invention. As Figure 1 shown, the method includes the following steps S101 to S104.

[0054] S101. Obtain the design specifications of the photovoltaic power station and the site coordinate information, and determine the installation inclination range and basic parameters.

[0055] In one embodiment, determine the installation inclination range according to the design specifications of the photovoltaic power station, and estimate the reflectivity of the selected site area according to the site coordinate information; the basic parameters include the geographical location information of the photovoltaic system installation, the reflectivity of the site area, the component installation type of the photovoltaic system, the orientation of the photovoltaic array, the number of rows of the photovoltaic array, and the type of inverter.

[0056] Specifically, the design specifications of the photovoltaic power station refer to the standards or regulations regarding the design of the photovoltaic power generation system, including the design requirements of the system, equipment selection, installation specifications, etc. It provides the technical specifications and design guidelines that should be followed during the construction of the photovoltaic power station to ensure the safety, efficiency and feasibility of the system. For example, the specifications may stipulate the maximum power of the photovoltaic components, the selection requirements of the inverter, the arrangement method of the photovoltaic array, etc.

[0057] In the embodiment, this specification also involves the determination of the installation inclination range. Different geographical locations and installation environments may have different optimal installation inclinations, and the design specifications provide how to determine the appropriate installation inclination based on these factors.

[0058] The site coordinate information refers to the geographical coordinate information of the specific construction location of the photovoltaic power station, including longitude and latitude. The site coordinate information is crucial for the design of the photovoltaic system because it determines the solar radiation amount received by the photovoltaic array, the orientation of the photovoltaic system, the installation tilt angle, and the estimated climate conditions (such as light intensity, wind speed, precipitation, etc.).

[0059] Based on the site coordinates, the solar radiation conditions in the area can be further analyzed, and factors such as reflectivity can be estimated. For example, in ocean or desert areas, the surface reflectivity is relatively high, while in urban or areas with more vegetation coverage, the reflectivity may be relatively low.

[0060] The installation tilt angle range includes: The installation tilt angle refers to the tilt angle of the photovoltaic module relative to the ground. The installation tilt angle of the photovoltaic system has a great impact on its power generation performance, and the optimal tilt angle can maximize the absorption effect of the photovoltaic array on solar radiation. The geographical location, seasonal changes, and weather conditions in different regions will all affect the optimal installation tilt angle.

[0061] By analyzing the site coordinate information, designers can estimate the solar radiation conditions in the area, and thus determine a reasonable installation tilt angle range. In the embodiment, the design specification provides a reasonable tilt angle range (such as 10° to 20°) to ensure that the photovoltaic module can maximize the power generation efficiency in most cases.

[0062] The installation geographical location information of the photovoltaic system refers to the detailed geographical information of the construction location of the photovoltaic power generation system, including geographical coordinates, climate conditions, solar radiation intensity, etc. The geographical location will affect the sunshine duration, solar altitude angle, etc., and thus affect the power generation capacity of the photovoltaic system.

[0063] The site area reflectivity refers to the surface reflectivity of the area where the photovoltaic power station is located (such as the reflectivity of deserts, oceans, cities, or grasslands). Areas with higher reflectivity (such as oceans and snowfields) will increase the radiation energy received by the photovoltaic module, and thus affect the calculation of the power generation amount.

[0064] The component installation type of the photovoltaic system includes the specifications and types of photovoltaic panels (monocrystalline silicon, polycrystalline silicon, etc.), and the component layout method (fixed or tracking type). These parameters will affect the power generation efficiency and cost of the system.

[0065] The orientation of the photovoltaic array refers to the installation orientation of the photovoltaic array relative to the due south direction. In order to maximize sunlight irradiation, the photovoltaic array usually needs to face the equator (due south in the Northern Hemisphere and due north in the Southern Hemisphere).

[0066] The number of photovoltaic array arrangements refers to the number of photovoltaic modules arranged. The array arrangement method needs to consider the space limitation of the site and the overall layout of the photovoltaic system to ensure that there is no shading between the components.

[0067] An inverter is a device that converts direct current (DC) generated by photovoltaic modules into alternating current (AC). Different types of inverters (such as centralized inverters or string inverters) can affect the efficiency, reliability, and maintenance costs of a photovoltaic system.

[0068] These basic parameters jointly determine the design scheme of a photovoltaic power station, affecting the overall performance, economic benefits, and long-term stability of the system. Therefore, accurate site information and design specifications are prerequisite conditions for ensuring the efficient operation of a photovoltaic system.

[0069] In one embodiment, the installation tilt range is preferably 10° to 20°.

[0070] S102. Calculate the arrangement spacing at different installation tilts, determine the optimal installation tilt and the optimal arrangement spacing, then calculate the power generation at different installation heights, determine the maximum power generation and the corresponding optimal installation height to obtain the optimal arrangement condition.

[0071] In this embodiment, the installation tilt of the photovoltaic system has a very significant impact on power generation because it determines the receiving angle of solar radiation. The arrangement spacing refers to the horizontal and vertical spacing between photovoltaic arrays. The arrangement spacing needs to be adjusted according to the installation tilt of the photovoltaic array to avoid shadow occlusion between arrays and ensure that each photovoltaic module can receive sufficient sunlight for most of the time.

[0072] The shadow occlusion principle means that to ensure the power generation efficiency of the system, it is necessary to consider the shadow occlusion during the winter solstice (the day with the shortest daylight in a year). The solar altitude angle is the lowest on the winter solstice, so it is the most demanding situation. By calculating the arrangement spacing of the photovoltaic array at different installation tilts, shadow occlusion can be avoided at noon on winter days, thus ensuring that the photovoltaic array receives sunlight to the maximum extent.

[0073] In one embodiment, according to the principle that there is no shadow occlusion between photovoltaic arrays around 9:00 to 15:00 true solar time on the winter solstice, calculate the corresponding arrangement spacing for different installation tilts respectively.

[0074] Based on the installation tilt, its corresponding arrangement spacing, and the basic parameters, calculate the maximum power generation through photovoltaic system design software, and then determine the corresponding optimal installation tilt and the optimal arrangement spacing;

[0075] In one embodiment, referring to Figure 2 , the method includes the following steps S201 to S206.

[0076] S201. According to the initial value β of the installation tilt i , calculate the initial value D of the corresponding arrangement spacing i , and combine with the basic parameters to simulate the initial power generation P through photovoltaic system design softwarei ; where i is a positive integer, and β i , D i , P i are respectively the installation inclination angle, spacing, and power generation amount in the i-th state.

[0077] S202. Adjust the installation inclination angle β i+1 ;

[0078] S203. Calculate the corresponding arrangement spacing D i+1 , and obtain the new power generation amount P through simulation by photovoltaic system design software i+1 ;

[0079] S204. Compare the new power generation amount P i+1 with the initial power generation amount P i ;

[0080] S205. Within the installation inclination angle range, traverse all installation inclination angles, repeat the above steps S202 - S204, and compare with the relatively higher power generation amounts before;

[0081] S206. Determine the maximum power generation amount P' and the corresponding optimal installation inclination angle β and optimal arrangement spacing D.

[0082] In one embodiment, to simplify the steps and improve the optimization efficiency, the installation inclination angle can be adjusted in degrees. The initial value of the installation inclination angle is 10 degrees, and the installation inclination angle is adjusted to 11 degrees, and so on.

[0083] Specifically, assuming the initial value is 10 degrees, usually start with a relatively small inclination angle and adjust step by step.

[0084] The arrangement spacing is related to the installation inclination angle and needs to be adjusted according to the change of the inclination angle. At a relatively large inclination angle, the shading problem of the photovoltaic array is more serious, so the arrangement spacing needs to be increased. This value is usually calculated according to empirical formulas or using photovoltaic design software.

[0085] Test the power generation effect at different inclination angles by gradually increasing the installation inclination angle. For example, adjust from the initial inclination angle of 10 degrees to 11 degrees, and continue to increase gradually until reaching the maximum inclination angle range required by the design.

[0086] For each new inclination angle β i+1 , it is necessary to calculate the corresponding arrangement spacing D i+1 to ensure that the shadow occlusion between arrays is minimized at different installation inclination angles.

[0087] Use photovoltaic system design software to recalculate the new power generation amount P i+1 to see if the power generation amount increases with the change of the installation inclination angle and arrangement spacing.

[0088] Compare the generated power after each adjustment with the previously calculated generated power to find the higher generated power. This can screen out the better installation tilt angle and arrangement spacing.

[0089] Within the installation tilt angle range (e.g., 10 degrees to 30 degrees), traverse all tilt angles and repeat the above steps (S202 to S204) to find the optimal tilt angle. Each time, compare the newly calculated generated power with the previous better generated power to ensure the maximum generated power is obtained.

[0090] After completing the calculation and comparison of all installation tilt angles, select the tilt angle with the maximum generated power and the corresponding arrangement spacing as the optimal configuration. Through this step, the optimal installation tilt angle (β) and the optimal arrangement spacing (D) are found, that is, under this configuration, the system can achieve the highest power generation efficiency.

[0091] To improve the optimization efficiency and simplify the steps, the installation tilt angle can be adjusted in degrees. For example, adjust by 1 degree each time, starting from 10 degrees, then 11 degrees, 12 degrees, etc. This can quickly find the optimal installation tilt angle through a limited number of calculations and save calculation time.

[0092] According to the optimal installation tilt angle, the optimal arrangement spacing, and the basic parameters, calculate the highest generated power through photovoltaic system design software, and then determine the corresponding optimal installation height to obtain the optimal arrangement condition.

[0093] The installation height usually refers to the height of the photovoltaic array from the ground. It is usually closely related to the arrangement spacing because increasing the installation height helps to reduce shadow occlusion and also improves the ventilation and heat dissipation of the photovoltaic modules, reducing the impact of temperature on the power generation efficiency. According to the optimal installation tilt angle and arrangement spacing, further determine the optimal installation height through photovoltaic system design software. In some cases, the optimal installation height may need to consider factors such as terrain undulation, wind speed, and structural strength.

[0094] Through the above calculation and optimization process, the finally obtained "optimal arrangement condition" means:

[0095] Optimal installation tilt angle: enables the photovoltaic array to receive the maximum solar radiation throughout the year.

[0096] Optimal arrangement spacing: ensures no shadow occlusion between arrays and improves the space utilization efficiency of the system.

[0097] Optimal installation height: optimizes the ventilation and heat dissipation conditions of the array and reduces the negative impact of temperature on the power generation efficiency.

[0098] These parameters work together to ensure the maximization of the power generation efficiency of the photovoltaic power station, thereby improving the economic benefits and sustainability of the system.

[0099] In one embodiment, referring to Figure 3 , the method includes the following steps S301 to S306.

[0100] S301. According to the optimal installation tilt angle β, the optimal arrangement spacing D, and the basic parameters, simulate the power generation amount at the initial installation height h j to obtain the initial power generation amount P j ; where j is a positive integer, and h j , P j are the installation height and the power generation amount in the j-th state, respectively.

[0101] S302. Adjust the installation height h j+1 ;

[0102] S303. Simulate to obtain the new power generation amount P j+1 ;

[0103] S304. Compare the new power generation amount P j+1 with the initial power generation amount P j ;

[0104] S305. Traverse all installation heights, repeat the above steps S302 to S304, and compare with the relatively higher power generation amounts before;

[0105] S306. Determine the maximum power generation amount P to obtain the corresponding optimal installation height.

[0106] In one embodiment, the installation height is between 0 and 3 m.

[0107] Specifically, it is first necessary to have determined the optimal installation tilt angle β and the optimal arrangement spacing D. Next, simulate the power generation situation in the current configuration through a photovoltaic system design software (such as PVsyst).

[0108] When simulating, in addition to the installation tilt angle β and the arrangement spacing D, some basic parameters also need to be considered, such as the geographical location (latitude and longitude) of the site, climate data (such as radiation intensity, temperature), the model of the photovoltaic module, the characteristics of the inverter, etc. These parameters are crucial for the estimation of the power generation amount.

[0109] A suitable initial value is usually selected for the starting installation height. For example, the installation height may vary from 0.5 m to 3 m. Assume the initial height is h j = 1.0 m, and PVsyst will use this height to calculate the preliminary power generation amount Pj.

[0110] Through the PVsyst software, based on these parameters, the system power generation amount at the initial installation height can be simulated to obtain the preliminary power generation amount P j .

[0111] The initially simulated power generation P j will be used as a reference. Then, increase the installation height by 1 unit, for example, from h j = 1.0 m to h j+1 = 1.5 m. The adjusted height range is usually selected according to the actual situation of the project and generally should not exceed 3 m, otherwise it may increase costs.

[0112] After adjusting the installation height, the position of the photovoltaic array changes, which may affect the ventilation, lighting, and shadow occlusion effects of the array. Therefore, after each height adjustment, it is necessary to re-evaluate the power generation efficiency of the system.

[0113] After adjusting the installation height, use photovoltaic system design software (such as PVsyst) to simulate the power generation again. At different installation heights, factors such as occlusion, air flow, and temperature between photovoltaic modules will be different, so the power generation will change. At this time, PVsyst will calculate the new power generation P j+1 and provide data for subsequent comparison.

[0114] In this step, compare the newly simulated power generation P j+1 with the initial power generation P j to evaluate whether the power generation effect of the new installation height has improved. If the new power generation P j+1 is greater than the initial power generation P j , it indicates that increasing the installation height may have a positive impact on power generation.

[0115] Next, traverse different values of the installation height and repeat steps S302 to S304. After each adjustment of the installation height, PVsyst will simulate the new power generation and compare it with the previous power generation.

[0116] For example: starting from the initial height h j = 1.0 m, adjust to h j+1 = 1.5 m and simulate the power generation. Then adjust to h j+2 = 2.0 m and simulate the new power generation again. Continuously adjust the installation height to gradually obtain the power generation at different installation heights until the power generation within all height ranges has been evaluated. During this process, compare the power generation at different heights and find the maximum power generation.

[0117] After completing the traversal and comparison, finally determine the maximum power generation and the corresponding optimal installation height. At this time, not only the installation tilt angle and arrangement spacing have been optimized in the photovoltaic system design, but also the most suitable installation height for the system has been found. Through this series of optimizations, the power generation efficiency of the system can be maximized.

[0118] In addition, the range of installation height is usually set according to the specific requirements of the project. Generally speaking, the installation height should be kept within a reasonable range. Too low may cause ground obstruction or excessive temperature, while too high may increase the structural cost. The specific range can be determined based on the following factors:

[0119] Terrain conditions: For example, flat or mountainous terrain may affect the selected height.

[0120] Air circulation: Increasing the installation height helps with the heat dissipation of photovoltaic modules, especially in high-temperature environments.

[0121] Shadow impact: A higher installation height can reduce the shadow obstruction between adjacent photovoltaic modules, especially in winter or at dawn and dusk.

[0122] Therefore, the range of installation height can vary from 0.0 meters to 3.0 meters, and the specific upper and lower limits depend on the project requirements and the actual site conditions.

[0123] Those of ordinary skill in the art can realize that, in combination with the optimal layout conditions described in the embodiments disclosed herein, to ensure the maximization of the power generation efficiency of the photovoltaic power station, whether adjusting to obtain the best installation tilt angle and the best layout spacing first, and then adjusting to obtain the best installation height, or adjusting to obtain the best installation height first, and then adjusting to obtain the best installation tilt angle and the best layout spacing, the object of the present invention can be achieved. Professional technicians can use different methods for each specific application to achieve the described functions, but such implementation should not be considered to exceed the scope of the present invention.

[0124] In this process, PVsyst software is one of the most commonly used photovoltaic system design tools. PVsyst software is currently one of the more authoritative photovoltaic system auxiliary design software. A large number of system calculation methods, tools, and formulas are integrated in the software, such as component spacing calculation, shadow simulation, shading electrical performance analysis, power generation simulation, etc., and it can relatively completely conduct research, design, and data analysis on the photovoltaic power generation system. It can help photovoltaic designers optimize the system and evaluate the performance. PVsyst has the following characteristics:

[0125] Automatically calculate the reasonable spacing between modules according to the size and installation tilt angle of the photovoltaic modules. Optimize the installation position and spacing by simulating the shading effect of the array. Simulate the annual power generation of the photovoltaic system according to specific geographical locations, climate conditions, component performance, and other factors. Analyze the impact of the shading effect caused by adjacent arrays or other buildings on power generation under different installation configurations.

[0126] Through the detailed simulation of PVsyst, the performance of the system at different installation heights can be comprehensively evaluated, and the best design configuration can be finally determined.

[0130] Where, W 1 is the total radiation energy received on the surface of the offshore photovoltaic system within the swing period T of the regular wave; I n is the radiation energy reaching the earth's surface; T is the swing period of the regular wave; t is the time variable; θ is the incident angle of sunlight; r 1 is the sea surface reflectivity; H is the solar altitude angle; α is the swing angle of the floating body under the influence of the regular wave; β is the optimal installation inclination angle.

[0131] Based on the optimal layout condition, calculate the total radiation energy received on the surface of the photovoltaic system on the ground within the swing period of the regular wave; in one embodiment, the calculation formula is as follows:

[0132]

[0133] Where, W 2 is the total radiation energy received on the surface of the photovoltaic system on the ground within the swing period T of the regular wave, I n is the radiation energy reaching the earth's surface; T is the regular wave period; t is the time variable; θ is the incident angle of sunlight; r 2 is the ground reflectivity; H is the solar altitude angle; β is the optimal installation inclination angle.

[0134] Under the optimal layout condition, the calculation formula for the ratio of the total radiation energy received on the surface of the photovoltaic system of the sea-land system in the same period is as follows:

[0135] η = W 1 / W 2

[0136] Where, η is the ratio of the total radiation energy received on the surface of the photovoltaic system of the sea-land system in the same period.

[0137] The smaller the η ratio, the greater the adverse impact of the sea wave on the floating photovoltaic system, and it is necessary to increase the ratio as much as possible in the design. Based on this ratio, judge the degree of adverse impact of the sea wave on the floating photovoltaic system. Refer to Figure 5, under the condition of the optimal layout working condition, the larger the swing angle α of the floating body, the smaller the total radiation energy ratio η, that is, the power generation of the floating photovoltaic system also decreases accordingly.

AQWA software is an integrated module in the finite element analysis software ANSYS, which can perform hydrodynamic characteristic analysis and calculation on objects of various sizes and structures. Among many wave engineering and hydrodynamic simulation software, it has wide applications and high credibility.
