[0017] like Figure 1 As shown, a fishery-solar complementary photovoltaic power generation system provided by an embodiment of the present invention is characterized in that the system comprises: The information acquisition module 100 is used to acquire site information, which includes the fish pond area, fish pond depth, aquatic plant species and fish, and to acquire photovoltaic power generation information, which includes photovoltaic modules, inverters and brackets.

[0018] In this system, the information acquisition module 100 acquires site information, including the fish pond area, fish pond depth, aquatic plant species and fish. The fish pond area determines the maximum coverage area where photovoltaic modules can be installed and the total scale of aquaculture. The fish pond outline is mapped by drone or GPS to calculate the water surface area. The depth of the fish pond is related to the volume of the water body, which directly affects the living environment of aquatic plants and fish, as well as the distribution of dissolved oxygen. Use a depth sounder or a water depth pole to measure points at different locations in the fish pond and calculate the average depth. The type of aquatic plant determines its photosynthetic efficiency and sensitivity to shading. Collect aquatic plant samples and identify them using botanical classification tools. Fish species affect the extent to which photovoltaic shading affects their growth, such as sensitivity to water temperature and dissolved oxygen, Get photovoltaic power generation information, which includes photovoltaic modules, inverters and brackets. The efficiency, area and layout of photovoltaic modules determine the power generation capacity and shading ratio. Get the technical parameters of photovoltaic modules, including efficiency and size. The inverter converts the direct current generated by the photovoltaic panel into alternating current, which affects the power generation efficiency. The inverter efficiency, maximum power and other parameters are obtained. The bracket design determines the angle of the photovoltaic module, the shading ratio and the impact on the water body. The bracket is designed according to the actual situation of the fish pond.

[0019] The installation module 200 is used to obtain the initial installation data of the photovoltaic components, obtain the water quality data, calculate the initial power generation according to the initial installation data, and calculate the initial aquatic production according to the water quality data.

[0020] In this system, the installation module 200 obtains the initial installation data of the photovoltaic module. In order to calculate the initial power generation P and aquatic production Y of the photovoltaic module, it is necessary to obtain the initial installation data and water quality data of the photovoltaic module in detail. The initial power generation is calculated based on the initial installation data. The initial power generation can be obtained through the photovoltaic power generation information obtained previously. ,The target power generation is the core parameter of the photovoltaic system design, which determines the total installation area of ​​the components and the system configuration.,The initial installation area is the total area occupied by the photovoltaic components on the water surface, which is calculated by the target power generation and the component efficiency; Combined with the site information obtained previously, the initial aquatic production is calculated based on water quality data. Dissolved oxygen is an important indicator for the survival of aquatic organisms, and pH reflects the acid-base balance of the water body, which has an important impact on aquatic organisms. By fully obtaining initial installation data and water quality information, combined with calculation and analysis, a scientific basis can be provided for the balanced development of photovoltaic power generation and aquaculture, achieving a win-win benefit.

[0021] The comparison module 300 is used to compare the initial power generation with the expected power generation to obtain a first comparison result, compare the initial aquatic production with the expected aquatic production to obtain a second comparison result, and adjust the initial installation data according to the first comparison result and the second comparison result.

[0022] In this system, the comparison module 300 compares the initial power generation with the expected power generation and calculates the deviation. The deviation reflects the difference between the actual initial power generation and the expected power generation. The deviation formula is ΔP=P 实际 -P 预计 , adjust the initial installation data according to the deviation size to obtain the first comparison result, If ΔP>0, the actual power generation is higher than expected, and the installation density can be optimized to reduce the impact of shading on aquatic production.

[0023] If ΔP<0, the actual power generation is lower than expected, increase the number of modules N, improve the module efficiency η, and optimize the tilt angle to increase the radiation per unit area G; Compare the initial aquatic production with the expected aquatic production and calculate the deviation. The deviation reflects the difference between the actual initial aquatic production and the expected aquatic production. The deviation formula is ΔY=Y 实际 -Y 预计 , adjust the breeding and installation plan according to the deviation size: If ΔY>0, the actual aquatic production is higher than expected, and the coverage density of PV panels can be appropriately increased.

[0024] If ΔY<0, the actual aquatic production is lower than expected, optimize the shading ratio, reduce the installation density, add oxygenation equipment or improve the water quality.

[0025] In order to optimize the synergistic benefits of photovoltaic power generation and aquaculture, we can compare the actual initial power generation with the expected power generation, the actual initial aquatic production with the expected aquatic production, analyze the deviations and adjust the initial installation data to make the system performance reach the expected target.

[0026] The effect module 400 is used to obtain the adjusted installation data, obtain the power generation and aquatic product output influence function, compare the installation data with the influence function, and determine the fish-light complementary effect.

[0027] In this system, the effect module 400 obtains the adjusted installation data and obtains the impact function of power generation and aquatic production. In the fish-light complementary system, the adjusted installation data is closely related to the impact function of power generation and aquatic production. The impact function not only includes positive impacts, such as increased power generation and ecological optimization, but also needs to evaluate negative impacts, such as excessive shading and decreased dissolved oxygen in water. By comparing the installation data with the impact function, the effect of fish-photovoltaic complementarity can be determined. By comparing the adjusted installation data with the ecological impact function EII (ecological impact index), the effect of the fish-photovoltaic complementary system can be scientifically evaluated.

[0028] like Figure 2 As shown, as a preferred embodiment of the present invention, the installation module 200 includes: The initial unit 201 is used to obtain the initial installation data of the photovoltaic components, the initial installation data including the target power generation, the initial installation area and the initial installation density, and to obtain the water quality data, the water quality data including the dissolved oxygen content, pH value and temperature of the water body.

[0029] In this module, the initial unit 201 obtains the initial installation data of the photovoltaic modules, and the initial installation data includes the target power generation, the initial installation area and the initial installation density. The target power generation is the core parameter of the photovoltaic system design, which determines the total installation area and system configuration of the modules, and determines the daily or annual power generation demand. The initial installation area is the total area occupied by the photovoltaic modules on the water surface, which is calculated by the target power generation and the module efficiency; area A: total area of ​​PV modules (unit: m²), P: target power generation (unit: kWh / day), η: efficiency of PV modules (usually 15%-22%), G: average daily solar radiation (unit: kWh / m²); Installation density refers to the proportion of photovoltaic panels to the water surface area, usually expressed as a percentage. Density D = A / A 鱼塘 D: Installation density, A 鱼塘 Total water surface area of ​​fish pond (unit: m²), Obtain water quality data, which includes dissolved oxygen content, pH value and temperature. Dissolved oxygen content is an important indicator for the survival of aquatic organisms. Too low dissolved oxygen will cause fish to die of hypoxia. pH value reflects the acid-base balance of the water body. The suitable pH range for aquaculture is 6.5-8.5. Too low or too high pH value will inhibit the normal metabolism of fish. Water temperature is an important factor affecting fish metabolism and growth rate.

[0030] The initial power generation unit 202 is used to obtain the total area A of the photovoltaic module, the average daily radiation per unit area G after tilting, the overall efficiency of the system η, and calculate the initial power generation according to the initial installation data. .

[0031] In this module, the initial power generation unit 202 obtains the total area A of the photovoltaic modules, obtains the daily average radiation per unit area G after tilting, and obtains the system comprehensive efficiency η. The total area of ​​the photovoltaic modules is the coverage area of ​​all installed photovoltaic modules on the water surface. The daily average radiation per unit area G after tilting is the actual solar radiation received by the photovoltaic modules, which is affected by the tilt angle of the modules and the local sunshine conditions. G=G 日均太阳辐射量 cos(θ) G 日均太阳辐射量 : average daily solar radiation on the horizontal plane (unit: kWh / m²), θ: tilt angle of the PV module (unit: degree), The overall system efficiency η is the comprehensive result of the PV module efficiency, inverter efficiency and other system losses. Calculate the initial power generation based on the initial installation data. .

[0032] The initial aquatic production unit 203 is used to obtain the total biomass B, which includes the fish density of the water body, the feed conversion rate FCR, the number of growth cycles C, and calculate the initial aquatic production according to the water quality data. .

[0033] In this module, the initial aquatic production unit 203 obtains the total biomass B, which is the sum of the mass of all fish in the fish pond, depending on the volume of the fish pond and the fish density per unit volume of water. The feed conversion rate FCR is the amount of feed required for the growth of unit mass of fish, reflecting the breeding efficiency. The number of breeding cycles C refers to the number of breeding cycles completed each year; Calculate the initial aquatic production based on water quality data. , by scientifically acquiring and calculating data, the initial aquatic production can be accurately assessed, providing a reliable basis for aquaculture management and profit forecasting.

[0034] like Figure 3 As shown, as a preferred embodiment of the present invention, the comparison module 300 includes: The first comparison unit 301 is used to compare the initial power generation with the expected power generation to obtain a first comparison result, and to compare the initial aquatic product output with the expected aquatic product output to obtain a second comparison result.

[0035] In this module, the first comparison unit 301 compares the initial power generation with the expected power generation and calculates the deviation. The deviation reflects the difference between the actual initial power generation and the expected power generation. The deviation formula ΔP=P 实际 -P 预计 , adjust the initial installation data according to the deviation size to obtain the first comparison result, If ΔP>0, the actual power generation is higher than expected, and the installation density can be optimized to reduce the impact of shading on aquatic production.

[0036] If ΔP<0, the actual power generation is lower than expected, increase the number of modules N, improve the module efficiency η, and optimize the tilt angle to increase the radiation per unit area G; Compare the initial aquatic production with the expected aquatic production and calculate the deviation. The deviation reflects the difference between the actual initial aquatic production and the expected aquatic production. The deviation formula is ΔY=Y 实际 -Y 预计 , adjust the breeding and installation plan according to the deviation size: If ΔY>0, the actual aquatic production is higher than expected, and the coverage density of PV panels can be appropriately increased.

[0037] If ΔY<0, the actual aquatic production is lower than expected, optimize the shading ratio, reduce the installation density, add oxygenation equipment or improve the water quality.

[0038] The second comparison unit 302 is used to obtain a standard baseline, which includes the light requirements of aquatic plants, dissolved oxygen requirements of fish, and water temperature requirements, and compare the first comparison result and the second comparison result with the standard baseline.

[0039] In this module, the second comparison unit 302 obtains the standard baseline, which includes the light requirements of aquatic plants, the dissolved oxygen requirements of fish and the water temperature requirements. The shading ratio of the photovoltaic module will affect the photosynthesis of aquatic plants, thereby affecting the ecological balance of the water body and the living environment of fish. For example, the light compensation point of duckweed is 10-15μmol / m² / s, and the light saturation point is 100μmol / m² / s; the light compensation point of Vallisneria is 20μmol / m² / s, and the light saturation point is 200μmol / m² / s; the light compensation point of Hydrilla verticillata is 15μmol / m² / s, and the light saturation point is 150μmol / m² / s; Fish need enough dissolved oxygen for normal metabolism and growth. Insufficient dissolved oxygen will lead to fish hypoxia or even death. Grass carp: dissolved oxygen ≥3-5 mg / L, silver carp: dissolved oxygen ≥5 mg / L, carp: dissolved oxygen ≥3 mg / L. Water temperature directly affects the metabolic rate and feeding activity of fish, grass carp: 20℃-30℃, silver carp: 22℃-28℃, carp: 15℃-30℃, Obtaining the standard baseline is an important basis for judging whether the power generation and aquatic production are reasonable. The standard baseline includes the light requirements of aquatic plants, the dissolved oxygen requirements of fish, and the water temperature requirements. By comparing the first comparison results and the second comparison results with these standard baselines, the operating effects of photovoltaic power generation and aquaculture systems can be scientifically evaluated, and optimization and adjustment plans can be formulated.

[0040] The third comparison unit 303 is used to obtain a third comparison result, obtain an adjustment plan, and adjust the initial installation data according to the third comparison result and the adjustment plan.

[0041] In this module, the third comparison unit 303 obtains the third comparison result, which is the result of comparing the first comparison result and the second comparison result with these standard baselines. Through the third comparison result, the comprehensive impact of the installation of the photovoltaic system on power generation and water ecology is evaluated: power generation dimension: evaluate whether the power generation target is met, water production dimension: evaluate the impact of shading ratio and water quality on aquaculture; If the third comparison result is > 0, it means that the system is running well and no major adjustments are needed. If the third comparison result is < 0, the system deviation is too large and needs to be adjusted. Adjustment of power generation system: increase the number of photovoltaic modules N and the total area of ​​modules A; optimize the tilt angle θ to increase the average daily radiation per unit area G; clean the surface of modules regularly to reduce the impact of dust on efficiency.

[0042] Adjustments to the aquaculture system: reduce the shading ratio of photovoltaic modules (from 50% to 45%); increase the operating time of oxygenation equipment to ensure that the dissolved oxygen content meets the demand (≥5 mg / L); regularly monitor water quality and control pH and water temperature.

[0043] like Figure 4 As shown, as a preferred embodiment of the present invention, the effect module 400 includes: The impact unit 401 is used to obtain the adjusted installation data and determine the positive impact and negative impact according to the installation data.

[0044] In this module, the impact unit 401 obtains the adjusted installation data and obtains the impact function of power generation and aquatic production. In the fish-light complementary system, the adjusted installation data is closely related to the impact function of power generation and aquatic production. The impact function not only includes positive impacts, such as increased power generation and ecological optimization, but also needs to evaluate negative impacts, such as excessive shading and decreased dissolved oxygen in water. Through a comprehensive analysis of positive and negative impacts, the fish-photovoltaic complementary system can be dynamically optimized to maximize the balance between power generation and aquaculture.

[0045] The influence function unit 402 is used to obtain the influence function of power generation and aquatic production.

[0046] In this module, the influence function unit 402 obtains the influence function of power generation and aquatic production. Obtaining the influence function EII of power generation and aquatic production is an important tool for evaluating the comprehensive benefits of photovoltaic power generation and aquaculture systems. The influence function consists of three core ecological indicators: light index, water temperature index and dissolved oxygen index. The weights w1, w2 and w3 are allocated according to the actual situation to quantify the balance between ecological and economic benefits. ; By constructing the influence function EII, the comprehensive benefits of photovoltaic power generation and aquaculture systems can be quantitatively evaluated, providing a scientific basis for the dynamic optimization of fish-photovoltaic complementary systems.

[0047] The effect unit 403 is used to compare the installation data with the influence function to determine the effect of fish-light complementarity.

[0048] In this module, the effect unit 403 compares the installation data with the influence function. The installation data directly affects the three sub-indices of the influence function EII, namely, the light index, the water temperature index and the dissolved oxygen index, affecting the light intensity on the water surface, thereby affecting the light index; affecting the water temperature and the ecological balance of the water body, thereby affecting the water temperature index and the dissolved oxygen index; affecting the dissolved oxygen index and the overall ecological health.

[0049] By comparing the adjusted installation data with the EII impact function, the effect of the fish-solar complementary system can be quantitatively evaluated, providing a scientific basis for further optimization.
