Description

Technical Field

[0001] The present invention relates to the field of intelligent photovoltaic control technology, and in particular to an automatic adjustment system and method for solar photovoltaic components used for renewable energy power generation. Background Art

[0002] With the growing global demand for renewable energy, photovoltaic technology has played a vital role in the transformation of the energy structure. Early solar photovoltaic systems mainly relied on photovoltaic panels installed at fixed angles. Although this design is simple, the photoelectric conversion efficiency is limited by the changes in solar radiation intensity in different seasons and times. In recent years, with the maturity of automation technology and intelligent control systems, the technology of automatically adjusting photovoltaic modules has gradually become a research hotspot. It aims to maximize energy capture efficiency by dynamically adjusting the direction and angle of photovoltaic panels, thereby improving overall power output and economic benefits.

[0003] Although methods for automatically adjusting photovoltaic panels have made significant progress, some challenges and limitations still exist. First, traditional photovoltaic systems mostly rely on a single type of sensor, which makes the system unable to fully perceive environmental factors, which in turn affects the accuracy of prediction models and the refinement of adjustment strategies. Second, most systems use simple mathematical models to predict lighting conditions and panel performance, and lack the ability to deeply mine and extract features from multi-dimensional environmental data, which limits prediction accuracy and adaptability to complex weather patterns. In addition, existing technologies lack sufficient consideration of the physical characteristics of photovoltaic panels in the generation and execution of adjustment strategies, resulting in poor results in extreme weather. Finally, traditional systems often ignore the impact of dynamic changes in panel shape on energy capture and fail to effectively integrate the environmental response matrix and eigenvector, thereby reducing the overall optimization potential and adaptability of the system.

The environmental response matrix E is composed of the power change rate of photovoltaic modules under different environmental conditions in historical data.

[0022] The Lagrange multiplier method is used to optimize the angle of the photovoltaic module, construct the Lagrange function L, and add physical constraints to the photovoltaic module.

[0023] The flexible photovoltaic module preliminarily adjusts the photovoltaic module according to the instruction issued by the central processing unit. The specific steps are as follows:

[0029] The specific steps for collecting the actual output data of the adjusted photovoltaic modules and evaluating the adjustment effect are as follows:

[0030] By integrating the environmental response matrix E and the eigenvector V, and considering the physical limitations of the PV modules, an evaluation function Q is constructed based on the output power P of the PV modules, the module change state S, and the module angle (g, φ).

[0031] As a preferred solution of the method for automatically adjusting solar photovoltaic modules for renewable energy power generation according to the present invention, wherein the evaluation result is fed back to the central processing unit to adjust the photovoltaic modules again, the specific steps are as follows:

[0032] A performance evaluation standard η is defined based on the system's design parameters and historical operating data. The system then monitors and calculates a parameter Q, reflecting current performance, in real time. This parameter is then compared with the preset evaluation standard η. When Q < η, the system's current regulation strategy and operating status are within acceptable limits, indicating good system performance and no immediate intervention is required. When Q ≥ η, system performance is deviating from expectations, with declining efficiency and other anomalies, triggering further analysis and response.

[0033] Once it is detected that the system Q≥η, the system will feed this information back to the central processing unit. After receiving the feedback, the central processing unit will start the optimization algorithm to analyze the reasons for the performance deviation. Based on the analysis results, the central processing unit will automatically adjust the angle and shape of the photovoltaic module.

[0050] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0051] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0052] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0053] Example 1, reference Figure 1, which is the first embodiment of the present invention, provides a method for automatically adjusting a solar photovoltaic assembly for renewable energy power generation, comprising the following steps:

[0054] S1. Deploy diversified sensors to collect environmental data and perform preprocessing and feature extraction on the environmental data.

[0055] Furthermore, light intensity sensors, temperature sensors, humidity sensors, wind speed sensors, and wind direction sensors are deployed at key locations around the photovoltaic panels. High-precision, low-power sensor models, such as the BH1750 light intensity sensor, the DHT22 temperature and humidity sensor, and the RS485 wind speed sensor, are selected to ensure data quality and system stability.

[0056] The data is transmitted to the central processing server in real time through the wireless module. After the central processing unit receives the raw data transmitted by the sensor network, it first performs data cleaning to eliminate outliers and noise interference. The outlier limit is determined by the 3σ principle based on statistics. The expression is:

[0057]

[0058] Among them, Z i is the Z-socre of the i-th data point, x i is the original data point, x' is the sample mean, s is the sample standard deviation, and the threshold is set to 3. That is, when |Zi|>3, the data point is marked as an outlier. The outlier correction adopts the cubic spline interpolation method to ensure a smooth transition of the data curve.

[0059] Wavelet transform is applied to extract features to identify the local characteristics of the signal. The expression is:

[0060]

[0061] Among them, W(a, b) is the wavelet coefficient, x(t) is the original analog signal, ψ * is the conjugate of the wavelet basis function,

[0062] a is the scale parameter, b is the translation parameter, and t is a continuous real number;

[0063] Morlet wavelet is selected as the basis function because it has good time-frequency resolution and is suitable for time-frequency analysis of signals. Through wavelet transform, multi-scale features of signals, such as trend, periodicity and transient features, can be extracted.

[0064] The periodic pattern of temperature fluctuations is identified by Fourier transform, which is expressed as:

[0065]

[0066] Where F(k) is the spectral coefficient, x(n) is the original digital signal, N is the signal length, n is the sampling point index in the time domain, and k is the index in the frequency domain;

[0067] Based on the extracted features, construct the feature vector V, which is expressed as:

[0068] V=[W lt ,F tp ,h,v,d];

[0069] Among them, W lt is the characteristic of light intensity change trend, F tp is the temperature fluctuation pattern characteristic, h is the humidity level, v is the wind speed, and d is the wind direction code.

[0070] S2. Build a photovoltaic performance prediction model based on the processed environmental data set to predict future lighting conditions and optimal component adjustment strategies.

[0071] Furthermore, the feature vector V is paired with the output power P of the photovoltaic module to form the data set D required for supervised learning, which is expressed as:

[0072]

[0073] Among them, V i is the feature vector of the i-th observation, P i is the corresponding PV module output power, N is the total number of observations;

[0074] Assuming that the future trends of light intensity, temperature, humidity, wind speed, and wind direction follow the laws of historical meteorological data, the photovoltaic performance prediction model is used to predict the output power of photovoltaic modules under future lighting conditions. The expression is:

[0075]

[0076] in, is the predicted output power under future lighting conditions, V f It represents the feature vector of future lighting conditions;

[0077] Subsequently, the dataset D is divided into a training set D and a training set D according to the ratio of 70% and 30%. tr and the test set D te , to ensure the effectiveness of model training and performance evaluation, on the test set D te The model performance is evaluated on the y-axis, and the root mean square error is used as the evaluation indicator. The expression is:

[0078]

[0079] Based on the predicted future photovoltaic module output power R, a genetic algorithm is used to optimize the tilt angle and azimuth angle of the module to maximize the energy capture efficiency. The genetic algorithm simulates the natural selection and genetic mechanism in the biological evolution process to find the global optimal solution and define the fitness function, which is expressed as:

[0080]

[0081] Where θ is the tilt angle of the photovoltaic module, and φ is the azimuth angle of the photovoltaic module.

[0082] It should also be noted that the range of RMSE is [0, +∞), and a smaller RMSE indicates that the model prediction is more accurate. The range of F(θ, φ) depends on the theoretical maximum output power of the PV module. A larger value means a higher energy capture efficiency. The range of F(θ, φ) also depends on the theoretical maximum output power of the PV module. The maximum value represents the optimal module adjustment strategy.

[0083] S3. Generate an adaptive adjustment strategy based on the prediction results.

[0084] Furthermore, a generalized linear model is introduced to integrate the eigenvector V and the environmental response matrix E to establish a sensitivity model of the PV module output power P to changes in environmental conditions. The environmental response matrix E is composed of the power change rate of the PV module under different environmental conditions in the historical data, and the expression is:

[0085] P(θ, φ, S) = β0 + β V V+β E E+β S S+β θ θ+β φ φ+∈;

[0086] Where β0 is the tilt angle coefficient, β φ is the azimuth coefficient, β V is the coefficient vector of the eigenvector V, β E is the coefficient vector of the eigenvector E, ∈ is the error term, β s is the shape change coefficient, S is a variable that represents the shape change state of the PV module, reflecting the degree to which the module changes its geometric shape in response to external instructions or environmental factors;

[0087] The Lagrange multiplier method is used to optimize the angle of the photovoltaic module, construct the Lagrange function L, and add physical restrictions to the photovoltaic module (such as the maximum tilt angle and azimuth angle range). The expression is:

[0088] L(θ,φ,λ)=P(θ,φ)-λg(θ,φ);

[0089] Where g(θ, φ) is the constraint function, λ is the Lagrange multiplier, and P(θ, φ) is the power prediction model. The optimal solution is found by solving the point where the partial derivatives of L with respect to θ, φ, and λ are equal to 0.

[0090] It should also be noted that when implementing this adaptive adjustment strategy based on a generalized linear model, it is necessary not only to monitor environmental parameters in real time, but also to take into account the physical limitations and long-term durability of photovoltaic modules. This means that although the pursuit of maximum power output is the main goal, it is necessary to dynamically adjust the angle of the module while avoiding exceeding its mechanical design limit to prevent physical damage or shortening its service life. In addition, due to the unpredictability of weather and other environmental conditions, the model should be robust and flexible enough to respond quickly and appropriately in emergencies. Finally, in order to ensure the economy and sustainability of the system, it is also necessary to evaluate and optimize the energy conversion efficiency and energy storage strategy in the energy management system to cope with fluctuations in grid demand.

[0091] S4. The flexible photovoltaic module preliminarily adjusts the photovoltaic module according to the instruction issued by the central processing unit.

[0092] Furthermore, we define the shape change function f S (S) Calculate the complex impact of shape change on power output and ensure a smooth transition of shape change. The expression is:

[0093] fS(S)=ath(bS)+c;

[0094] Where a is the amplitude of the control function, b is the steepness of the control function, and c is the offset;

[0095] Define the angle change function f A (θ, φ) calculates the complex effect of angle transformation on power output, and the expression is:

[0096] f A (θ,φ)=d sin(eθ)+f cos(gφ)+h;

[0097] Where d is the amplitude coefficient of the sine function, e is the coefficient of θ, f is the coefficient multiplied by the cos(gφ) term, g is the coefficient of φ, and h is a constant term;

[0098] The shape change function f S (S) and angle adjustment function f A (θ, φ) is used as a correction factor and integrated into the power prediction model. n Combined to form the predicted power output P pr,i , the expression is:

[0099] Ppr,i =P n ×f S (S)×f A (θ, φ);

[0100] Among them, P n is the power output unaffected by shape change and angle, p pr,i It is the predicted output power of the PV module at the i-th observation time after the shape and angle are adjusted.

[0101] It should also be noted that the adaptive adjustment of flexible photovoltaic modules not only relies on the instructions of the central processing unit, but also deeply integrates multiple links such as environmental monitoring, data preprocessing, feature extraction, performance prediction and strategy generation. This comprehensive system ensures that photovoltaic modules can flexibly adjust their shape and angle according to real-time environmental changes such as light intensity, temperature, humidity, wind speed and direction to pursue the optimal energy capture efficiency. During the adjustment process, the shape change function f S (S) and angle adjustment function f A The careful design of (θ, φ) takes into account both the maximization of power output and the physical limitations and mechanical life of the components, avoiding the damage that may be caused by over-adjustment. In addition, by closely integrating these functions with predictive models, the system can predict the power output at a specific observation moment after adjustment, thereby achieving forward-looking adaptive control.

[0102] S5. Collect the actual output data of the adjusted PV modules and evaluate the adjustment effect. The specific steps are as follows:

[0103] Integrating the environmental response matrix E and the eigenvector V, while considering the physical limitations of the PV modules, an evaluation function Q is constructed based on the output power P of the PV modules, the module change state S, and the module angle (g, φ). The expression is:

[0104]

[0105] Among them, g j (θ, φ) is the physical constraint function of the PV module angle, and M is the dimension of the angle constraint.

[0106] It should also be noted that η is not only a static comparison point, but also one of the key parameters that are dynamically adjusted during system performance monitoring and optimization. As the system ages, technology improves, or external environmental conditions change, the value of η may also need to be adjusted accordingly to maintain its effectiveness as a performance evaluation benchmark.

[0107] S6. Feedback the evaluation results to the central processing unit to adjust the photovoltaic components again.

[0108] Furthermore, a performance evaluation standard η is defined based on the system's design parameters and historical operating data. Subsequently, the system monitors and calculates a parameter Q reflecting current performance in real time. This parameter Q is compared with the preset evaluation standard η. When Q < η, the system's current regulation strategy and operating status are within an acceptable range, indicating good system performance and no need for immediate intervention. When Q ≥ η, system performance begins to deviate from expectations, with declining efficiency and other anomalies, triggering further analysis and response.

[0109] Once it is detected that the coefficient Q ≥ η, the system will feed this information back to the central processing unit. After receiving the feedback, the central processing unit will start the optimization algorithm to analyze the reasons for the performance deviation, including but not limited to improper component angle, shape changes or changes in environmental factors. Based on the analysis results, the central processing unit automatically adjusts the angle and shape of the photovoltaic module, such as adjusting the tilt angle and azimuth angle of the module through a motor, or fine-tuning the shape of the module (in flexible modules) to optimize the sunlight incident angle, improve lighting efficiency, and ensure that the system returns to an efficient operating state.

[0110] It should also be noted that the setting of the performance evaluation standard η needs to be based on historical data, theoretical models and actual application goals. It is a dynamic threshold that can be adjusted as external conditions change. In winter when the sunlight is weak, η may be lowered to make the system pay more attention to stability and durability. At the same time, the calculation of η should also consider multiple factors such as economic costs, maintenance needs and environmental impacts to ensure that the photovoltaic system maintains an efficient and environmentally friendly operating state throughout its life cycle. In addition, when the central processing unit receives feedback that exceeds the η threshold, it must not only adjust the angle and shape of the photovoltaic module in real time, but also analyze the root cause of the performance degradation, which may be obstruction, pollution, failure or design limitations, and then take targeted optimization measures or trigger maintenance processes to restore and improve system performance.

[0119] In summary, the present invention is as follows: the present invention relates to an automatic adjustment method and system for solar photovoltaic components for renewable energy power generation, aiming to improve the power generation efficiency of photovoltaic components through automated means. First, the system collects environmental data by deploying diversified sensors, and performs preprocessing and feature extraction to ensure the accuracy of the data. Secondly, based on the processed data, a photovoltaic performance prediction model is constructed to predict future lighting conditions, thereby generating the optimal component adjustment strategy. Then, the photovoltaic components are adaptively adjusted according to the instructions of the central processing unit, including preliminary adjustment of the angle and shape of the photovoltaic components to adapt to environmental changes. The system also collects the actual output data of the adjusted photovoltaic components, evaluates the adjustment effect, and feeds back the evaluation results to the central processing unit for further optimization and adjustment.

[0120] Example 2, referring to Table 1, is the second example of the present invention. To further verify the advancement of the present invention, experimental simulation data of the automatic adjustment method of solar photovoltaic components for renewable energy power generation are provided.

[0121] Two groups of identical photovoltaic modules were used: one group adopted the technical solution of the present invention, and the other group adopted a traditional fixed-angle photovoltaic system as a control. Each group of photovoltaic modules collected light intensity, temperature, humidity, and wind speed respectively.

[0122] First, the sensor deployment and data collection phase involves installing high-precision light intensity sensors BH1750, temperature and humidity sensors DHT22, and wind speed sensors RS485 around the two groups of photovoltaic panels, and sending real-time data to the central processing server via wireless modules.

[0123] Secondly, in the data processing and feature extraction stage, preprocessing operations are performed on the collected raw data to construct a comprehensive feature vector V, which contains the changing trend of light intensity, temperature fluctuation pattern, humidity level, wind speed and wind direction encoding.

[0124] Next, in the performance prediction and adjustment strategy generation step, a supervised learning model is trained based on the feature vector V and the actual output power P to predict the possible output power of the photovoltaic module under different future lighting conditions. The root mean square error (RMSE) is used to evaluate the accuracy of the prediction model on the test set.

[0125] Finally, in the adaptive adjustment and effect evaluation stage, the corresponding adaptive adjustment strategy is generated according to the prediction results, and the angle and shape of the photovoltaic modules are dynamically adjusted. The actual effect of the adjustment strategy is evaluated by continuously monitoring the adjusted output power and calculating the performance evaluation standard η.

[0126] The details are shown in Table 1:

[0129]

[0130] Analysis of the data in the table above shows that, under identical environmental conditions, the photovoltaic system of the present invention consistently outperforms conventional photovoltaic systems in terms of average daily output power. For example, under conditions of 45,000 lux, 25°C temperature, 60% humidity, and 3 m / s wind speed, the average daily output power of the photovoltaic system of the present invention is 5.2 kWh, while the conventional photovoltaic system only achieves 4.8 kWh. Similar trends are also observed in other environments. For example, under conditions of lower light intensity (5,000 lux), lower temperature (15°C), and higher humidity (80%), the output power of the photovoltaic system of the present invention remains at 3.0 kWh, significantly higher than the 2.7 kWh of the conventional system.

[0131] The photovoltaic system of this invention significantly improves the energy capture efficiency of photovoltaic modules through an adaptive regulation strategy, especially under unstable lighting conditions. Compared with traditional photovoltaic systems, it demonstrates significant innovation and advantages. This performance improvement is reflected not only in higher average daily output power, but also in improved system stability and longer module lifespan, providing a more advanced and practical technical solution for the field of solar power generation.

[0132] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
