Description

Technical Field

[0001] This application belongs to the field of power technology, specifically, it relates to a method for improving photovoltaic power output based on environmental perception and light reception status correction. Background Technology

[0002] Photovoltaic (PV) power generation is an important form of energy supply in integrated energy systems and distributed energy systems. Its output power is affected by factors such as solar altitude angle, solar azimuth angle, irradiance, module temperature, wind speed, dust accumulation, and PV module attitude. In actual operation, the light-receiving state refers to the comprehensive light-receiving situation of PV modules under the combined effects of solar irradiance, environmental conditions, and module attitude. The sun's position changes continuously over time, and factors such as dust accumulation on the module surface, changes in ambient temperature, and module attitude deviations all reduce the effective light-receiving capacity of PV modules, causing a deviation between the actual and theoretical output. Existing methods for improving PV output mainly include maximum power point tracking (MPPT), fixed tilt angle design, single-axis or dual-axis tracking control, and empirical angle adjustment. However, these methods usually focus on the electrical operating point or the geometric relationship of the sun's position, lacking comprehensive correction for multi-source environmental factors such as temperature, wind speed, dust accumulation, and actual output deviations.

[0003] Furthermore, existing methods for adjusting the tilt angle, azimuth angle, and light-receiving area of ​​photovoltaic modules typically rely on single calculations, lacking real-time feedback and iterative correction mechanisms for the adjustment effect. When modules are affected by cloud movement, partial shading, and temperature changes, the results of a single adjustment cannot accurately reflect the actual light-receiving conditions, resulting in limited improvement in photovoltaic output. Therefore, it is necessary to propose a photovoltaic output enhancement method that takes into account environmental perception, light-receiving condition correction, and feedback iterative optimization.

[0243] Where H represents the regulation effect index; This indicates the weight for determining the system's output. Indicates the weight for determining the expected deviation rate; This indicates the weight for determining the effective light-receiving area.

[0244] The equation for obtaining the regulation effect index of the photovoltaic system is as follows:

[0245] .

[0246] in, The weight for determining the system's output is set to 0.6; The weight for determining the expected deviation rate is set to 0.2; The weight for determining the effective light-receiving area is set to 0.2.

[0247] The system's operating status is determined based on the regulation effect index. The regulation effect determination threshold H... set If the value is 0.2, then H < H set This indicates that the increase in output power of the photovoltaic module after this adjustment did not meet the preset requirements, and it is determined that the adjustment operation of the photovoltaic module did not meet the validity conditions, and iterative evaluation is required.

[0248] The process of obtaining the regulation effect index of the photovoltaic system, updating the regulation parameters of the photovoltaic system, and verifying the regulation parameters includes:

[0249] When the regulation effect index of the photovoltaic system is not higher than the regulation effect index threshold, the deviation feedback gain is obtained, and the equation is:

[0250] ,

[0251] Among them, G f This represents the bias feedback gain.

[0252] Where H < H set At that time, the deviation feedback gain is determined based on the predicted output before adjustment, the corrected output after adjustment, and the angle deviation, and the target tilt angle and target azimuth angle are iteratively updated according to the deviation feedback gain.

[0253] Based on the deviation feedback gain, the updated values ​​of the target tilt angle and target azimuth angle are obtained, and the equation is as follows:

[0254] ,

[0255] in, and Let these represent the target inclination angle and target azimuth angle after the k-th iteration, respectively; and These represent the actual tilt angle and actual azimuth angle after the adjustment is executed in the k-th iteration, respectively. and These represent the target tilt angle update value and the target azimuth angle update value after the (k+1)th iteration, respectively.

[0256] If the updated target tilt angle or target azimuth angle exceeds the allowable range, a boundary correction is performed, and the tilt angle and azimuth angle after the boundary correction are used as the target tilt angle and target azimuth angle for the next iteration adjustment.

[0257] Boundary corrections are applied to the updated target inclination and azimuth values, using the following equations:

[0258] ,

[0259] in, This represents the updated target tilt angle value after the (k+1)th iteration following boundary correction. This represents the updated target azimuth angle after the (k+1)th iteration following boundary correction.

[0260] Among them, the parameters were continuously adjusted by iterative calculation, and it was verified that H≥H was satisfied after 6 iterations. set .

[0261] Each time, the corrected target tilt angle update value and target azimuth angle update value are obtained, and the relationship between the regulation effect index and the regulation effect index threshold of the photovoltaic system is obtained until the regulation effect index of the photovoltaic system is higher than the regulation effect index threshold.

[0262] The equation for obtaining the photovoltaic output optimization effectiveness index of the photovoltaic system is as follows:

[0263] ,

[0264] Among them, Q pv This index represents the effectiveness of photovoltaic power output optimization.

[0265] The equation for obtaining the photovoltaic output optimization effectiveness index of the photovoltaic system is as follows:

[0266] .

[0267] Based on the photovoltaic power output optimization effectiveness index, the effectiveness status of the photovoltaic power output optimization effectiveness index is determined by the following equation:

[0268] ,

[0269] Among them, Q M The threshold for determining effectiveness; Q H This indicates the threshold for determining high effectiveness.

[0270] Among them, Q M The threshold for determining effectiveness is 0.50; Q H The threshold for determining high efficiency is 0.60. After this adjustment, the photovoltaic system has reached a high efficiency level, indicating that the optimization method can significantly improve the photovoltaic output level and meet the preset performance requirements.

[0271] Therefore, the photovoltaic output optimization effect after the adjustment of the photovoltaic system is judged to have reached the high level of effectiveness. This indicates that after correcting the posture of the photovoltaic modules based on environmental parameters, light reception status and actual output deviation, and updating the feedback based on the adjustment effect, the actual light reception status of the photovoltaic modules can be effectively improved, the actual output power of the photovoltaic system can be increased, and the requirements for photovoltaic output improvement can be met.

[0272] Furthermore, to verify the adjustment effect of the photovoltaic output enhancement method based on environmental perception and light reception correction in this application under different environments and operating conditions, a photovoltaic system simulation model was established, including an adjustable tilt photovoltaic support, an azimuth adjustment mechanism, an environmental parameter monitoring module, a power acquisition module, and a controller. Under the same environmental parameters and initial operating conditions, the photovoltaic output, component adjustment parameters, and feedback iteration process before and after adopting the method of this application were compared and analyzed.

[0273] Figure 2 This image shows a comparison of photovoltaic output before and after adjustment in a photovoltaic output enhancement method based on environmental perception and light reception state correction, provided as an embodiment of this application. Figure 2As shown, during the diurnal variation of irradiance, the theoretical photovoltaic output exhibits a trend of first increasing and then decreasing with changes in solar irradiance conditions. Without correction for the light-receiving state, there is a significant deviation between the actual and theoretical photovoltaic output. By adopting the method of this application, the light-receiving state of the photovoltaic module is corrected by comprehensively considering factors such as solar position, irradiance, module temperature, dust accumulation, and the current attitude of the module. Based on the correction results, the module's operating state is adjusted, resulting in an overall photovoltaic output that is closer to the theoretical output, and the deviation in photovoltaic output is correspondingly reduced. This demonstrates that the method of this application can improve the effective light-receiving state of photovoltaic modules and increase the actual photovoltaic output power under different environmental conditions.

[0274] Figure 3 This image shows a comparison of the changes in the tilt angle and azimuth angle of a photovoltaic module before and after adjustment, illustrating a photovoltaic output enhancement method based on environmental perception and light reception correction provided in this application embodiment. Figure 3 As shown, the target tilt angle and target azimuth angle change dynamically over time as the solar altitude angle and solar azimuth angle change accordingly. Due to actual execution deviations in the photovoltaic module adjustment mechanism, there are certain differences between the actual tilt angle and actual azimuth angle and the target values. This application calculates an adjustment execution correction coefficient to feed back the actual execution state of the module to the photovoltaic output calculation and subsequent adjustment process, enabling the actual attitude of the module to be adjusted according to changes in the target sunlight state. This demonstrates that this application can dynamically correct the photovoltaic module attitude based on environmental changes and the actual execution state of the module, avoiding execution deviations caused by adjusting based solely on a single target parameter.

[0275] Figure 4 This document presents a feedback iteration process and optimization performance comparison chart for a photovoltaic power output enhancement method based on environmental perception and light reception state correction, as provided in an embodiment of this application. Figure 4 As shown, during the feedback iteration process, the adjustment effect index gradually improves with the increase of the number of iterations, eventually reaching the set adjustment effect index threshold. Simultaneously, the actual output of the photovoltaic system gradually increases with the continuous correction of the target tilt angle and target azimuth angle. After six iterations, the adjustment effect index meets the set threshold, and the feedback iteration process ends. Further comparison of the target output capacity, stability effect, and final results before and after adjustment shows that all evaluation results are improved after adopting the method of this application, and the photovoltaic output optimization effectiveness index meets the high-effectiveness judgment requirements. This demonstrates that the deviation feedback update mechanism constructed in this application can continuously correct target parameters based on the actual adjustment effect, improving the output level and adjustment effect of the photovoltaic system.

[0276] The beneficial effects of this application are as follows: by comprehensively considering the solar altitude angle, solar azimuth angle, irradiance, module temperature, dust accumulation status, and actual photovoltaic output, a photovoltaic light-receiving state correction mechanism is constructed. Based on the output deviation, the target tilt angle, target azimuth angle, and effective light-receiving area of ​​the photovoltaic module are dynamically adjusted so that the module operating status can match the current environmental conditions and actual light-receiving state, thereby reducing the deviation between the actual output and the expected output and improving the actual output capacity of the photovoltaic system.

[0277] Meanwhile, this application introduces a regulation execution correction and deviation feedback update mechanism. After the photovoltaic module executes the regulation command, the regulation effect is evaluated based on the actual tilt angle, actual azimuth angle, effective light-receiving area, and actual output. When the regulation effect fails to meet the set requirements, the target parameters are updated, allowing the regulation effect to gradually reach the preset requirements during the iterative process. Simulation results show that the method described in this application can improve the light-receiving state of the photovoltaic module, increase photovoltaic output and regulation effect, and reduce the deviation between the actual execution state and the target state of the module, thereby enhancing the adaptive regulation capability and operational reliability of the photovoltaic system under changing environmental conditions.
