Description

Technical Field

[0001] This application relates to the field of photovoltaic power generation technology, and more specifically, to a method, apparatus, and electronic device for determining the adjustment time of a support structure. Background Technology

[0002] Photovoltaic (PV) modules in a photovoltaic (PV) solar power plant are typically mounted on PV support structures. It's understandable that the solar altitude angle is not constant but changes over time. To achieve optimal power generation efficiency, the PV modules need to face the sun at a specific angle; therefore, the PV support structures supporting the modules also need to be fixed yet adjustable.

[0003] Fixed adjustable mounting systems are photovoltaic (PV) mounting systems with fixed tilt positions that allow manual adjustment of the module tilt angle. Compared to fixed mounting systems, fixed adjustable mounting systems generate more power, and compared to tracking mounting systems, they are less expensive, have a lower failure rate, and require less maintenance, thus gaining widespread use in PV power plants. Fixed adjustable mounting systems typically require adjustment a few times a year, each time moving from one tilt position to another.

[0004] The existing fixed adjustable support adjustment date is mainly calculated based on the monthly average tilt surface radiation of the power station at different tilt angles. The power station then randomly selects a date within that month for adjustment. The calculation process is rough, the accuracy is poor, and the impact of specific weather conditions is not taken into account. Therefore, it cannot guarantee the optimal power generation efficiency and power generation revenue of the photovoltaic power plant.

[0005] There is currently no effective solution to the above problems. Summary of the Invention

[0029] In related technologies, the adjustment date for fixed adjustable supports is mainly calculated based on the monthly average tilt surface radiation of the power station at different tilt angles. The power station then randomly selects a date within that month for adjustment. Therefore, this method suffers from problems such as a rough calculation process and poor accuracy.

[0036] Under the above operating environment, this application embodiment provides a method for determining stent adjustment time. Figure 2 This is a schematic diagram of a method for determining stent adjustment time according to an embodiment of this application, as shown below. Figure 2 As shown, the method includes the following steps:

[0037] Step S202: Based on the weather forecast data of each second time period in the first time period and the historical weather data corresponding to the first time period, determine the total horizontal irradiance of each third time period, wherein the first time period contains multiple second time periods and each second time period contains multiple third time periods.

[0038] In this embodiment, to facilitate the explanation of the method for determining the stent adjustment time, the second time period is taken as a day, and the third time period is taken as each moment of each day.

[0039] In the technical solution provided in step S202, before determining the total horizontal irradiance of each third time period based on the weather forecast data of each second time period in the first time period and the historical weather data corresponding to the first time period, the following steps are also included: determining the first time period by calculating the total radiation of the clear sky tilted surface corresponding to each second time period of the target support under various tilt angles, wherein the tilt angle is the angle between the photovoltaic power generation panel controlled by the target support and the horizontal plane.

[0040] In some embodiments of this application, determining the first time period by calculating the total radiation of the clear sky inclined surface corresponding to each second time period of the target support under various tilt angles during a preset period includes the following steps: determining the total radiation of the clear sky inclined surface corresponding to each second time period of the target support under various tilt angles during a preset period; if the total radiation of the clear sky inclined surface corresponding to two tilt angles is equal during a certain second time period, the second time period is determined as a candidate adjustment time period; and determining the second number of second time periods immediately before and after the candidate adjustment time periods as the first time period.

[0041] Specifically, the total solar radiation of the clear-sky tilt surface can be calculated daily (i.e., the second time period mentioned above) for each tilt angle based on the principles of celestial geometry. The total solar radiation of the clear-sky tilt surface refers to the total solar radiation of the tilt surface when there are no clouds in the sky. In this case, solar radiation only includes direct radiation and no scattered radiation. When the total solar radiation of the clear-sky tilt surface for the two tilt angles is equal or closest on a certain day, that day is determined as the ideal adjustment day (i.e., the candidate adjustment period mentioned above). The ideal adjustment day and n days before and after it (i.e., the second quantity mentioned above) are obtained as possible adjustment periods (i.e., the first time period mentioned above).

[0042] To maximize the power generation benefits from the fixed adjustable support, this application comprehensively considers the impact of weather factors when determining the adjustment time. Specifically, based on the weather forecast data for each second time period within the first time period and the historical weather data corresponding to the first time period, determining the total horizontal irradiance for each third time period includes the following steps: determining the weather type for each second time period within the first time period based on the weather forecast data; calculating the average total horizontal irradiance for the same weather type in historical periods corresponding to the first time period based on historical weather data, and using the average value as the total horizontal irradiance for the second time period corresponding to the weather type in the first time period; and determining the total horizontal irradiance for each third time period based on the total horizontal irradiance for each second time period within the first time period.

[0043] Specifically, obtain the weather forecast for the ideal adjustment date and n days before and after it (the possible adjustment period, i.e., the first time period mentioned above); for each day of the possible adjustment period (i.e., the first time period mentioned above), find the total horizontal radiation of all the same weather conditions in the same period of previous years based on the weather forecast data, and use the average value as the total horizontal radiation of that weather type in the possible adjustment period.

[0044] In some embodiments of this application, determining the total horizontal irradiance of each third time period based on the total horizontal irradiance of each second time period within the first time period includes the following steps: determining the clear-sky horizontal irradiance of each third time period; randomly selecting a first number of third time periods as random time periods within each second time period of the first time period, and randomly generating a random irradiance for each random time period, wherein the integral of the product of the random irradiance of the first number of random time periods and the time resolution is equal to a target difference, the target difference being the difference between the total horizontal irradiance corresponding to the second time period and the clear-sky horizontal irradiance corresponding to the second time period; calculating the difference between the clear-sky horizontal irradiance of the random time period and the random irradiance, and determining the difference as the total horizontal irradiance of the random time period; and determining the clear-sky horizontal irradiance corresponding to the remaining third time periods within the second time period, excluding the random time periods, as the total horizontal irradiance of the third time period.

[0045] Specifically, calculate the absolute value of the difference between the total horizontal irradiance of each day during the possible adjustment period (i.e., the first time period mentioned above) and the total horizontal irradiance of the clear sky on that day, denoted as a (i.e., the target difference mentioned above); calculate the total horizontal irradiance of the clear sky at each moment during each day during the possible adjustment period according to the principles of celestial geometry; randomly select m moments (i.e., the first number mentioned above) during the day (i.e., the random time period mentioned above), and randomly generate an irradiance (i.e., the random irradiance mentioned above) at each moment, such that the integral of the product of the m random irradiances at the m moments and the time resolution equals a. Then, the total horizontal irradiance of the selected m moments (i.e., the random time period mentioned above) = the total horizontal irradiance of the clear sky at that moment - the random irradiance at that moment, and the total horizontal irradiance of the remaining moments (i.e., the remaining third time periods mentioned above) = the total horizontal irradiance of the clear sky at that moment.

[0046] Step S204: The first target model is used to analyze the total horizontal irradiance input for each third time period to obtain the direct horizontal irradiance and the diffuse horizontal irradiance for each third time period. The first target model is used to indicate at least the correlation between the total horizontal irradiance and the diffuse horizontal irradiance.

[0047] This application's solution calculates the horizontal diffuse irradiance from the total horizontal irradiance by establishing a machine learning model. Specifically, it uses a first target model to analyze the total horizontal irradiance input for each third time period, obtaining the direct horizontal irradiance and the horizontal diffuse irradiance for each third time period. This includes the following steps: determining the air quality data for each third time period based on weather forecast data, wherein the air quality data includes at least one of the following: total suspended particulate matter data and relative humidity; determining the celestial geometric parameters corresponding to each third time period, wherein the celestial geometric parameters include at least one of the following: the horizontal surface outside the atmosphere. Total irradiance, declination angle, and hour angle are used to determine the horizontal diffuse irradiance for each third time period. The total horizontal irradiance, air quality data, and celestial geometric parameters for each third time period are input into the first target model to obtain the horizontal diffuse irradiance for each third time period. The first target model is used to indicate the correlation between the total horizontal irradiance, air quality data, celestial geometric parameters, and the horizontal diffuse irradiance. The first target model is trained based on historical total horizontal irradiance, historical air quality data, historical celestial geometric parameters, and corresponding historical horizontal diffuse irradiance. The direct horizontal irradiance is obtained by subtracting the total horizontal irradiance from the horizontal diffuse irradiance for each third time period.

[0048] As an optional implementation method, a machine learning model (i.e., the first target model mentioned above) can be trained based on historical data. Specifically, the total irradiance and the diffuse irradiance of the power station are obtained by using the total irradiance meter and the diffuse irradiance meter installed at the power station (the diffuse irradiance meter model can be removed after training). The ratio of the diffuse irradiance to the total irradiance is related to the ratio of the total irradiance to the total irradiance outside the atmosphere, the thickness of the solar radiation passing through the atmosphere, the air quality, and the relative humidity of the air.

[0049] Using total horizontal irradiance, total horizontal irradiance outside the atmosphere, declination angle, hour angle, total suspended particulate matter in the atmosphere, and relative humidity as input parameters, and horizontal diffuse irradiance as output parameter, a machine learning model is established and trained. Among them, the declination angle and hour angle determine the thickness of sunlight passing through the atmosphere, the total suspended particulate matter in the atmosphere reflects the air quality, the total horizontal irradiance outside the atmosphere, the declination angle, and the hour angle can be calculated based on the principles of celestial geometry, and the total suspended particulate matter in the atmosphere and relative humidity can be obtained from public channels (such as historical weather data);

[0050] After the model training is completed, inputting the total horizontal irradiance, the total horizontal irradiance outside the atmosphere, the declination angle, the hour angle, the total suspended particulate matter in the atmosphere, and the relative humidity of the air will yield the horizontal diffuse irradiance.

[0051] Specifically, the total horizontal irradiance, total horizontal irradiance outside the atmosphere, declination angle, hour angle, total suspended particulate matter in the atmosphere, and relative humidity of the air at each moment during the possible adjustment period (i.e., the first time period mentioned above) are input into the model (i.e., the first target model mentioned above) to obtain the horizontal diffuse irradiance at each moment. The horizontal direct irradiance at each moment = the total horizontal irradiance at that moment - the horizontal diffuse irradiance at that moment.

[0052] Step S206: Determine the total radiation of the inclined surface for each third time period based on the direct irradiance and diffuse irradiance of the horizontal surface for each third time period.

[0053] In some embodiments of this application, the total radiance of the inclined surface includes: the total radiance of the inclined surface before adjustment and the total radiance of the inclined surface after adjustment. Determining the total radiance of the inclined surface for each third time period based on the direct irradiance and diffuse irradiance of the horizontal surface for each third time period includes the following steps: inputting the direct irradiance, diffuse irradiance, latitude and longitude of the power station where the target support is located, and the tilt angle of the target support before adjustment into the second target model to obtain the total radiance of the inclined surface before adjustment for each third time period, wherein the second target model is used to indicate the correlation between the direct irradiance, diffuse irradiance, latitude and longitude, tilt angle and the total radiance of the inclined surface; inputting the direct irradiance, diffuse irradiance, latitude and longitude of the power station where the target support is located, and the tilt angle of the target support after adjustment into the second target model for each third time period of the first time period to obtain the total radiance of the inclined surface after adjustment for each third time period.

[0054] Specifically, the direct horizontal irradiance, diffuse horizontal irradiance, tilt angle to be adjusted of the power station (i.e., the tilt angle of the target support after adjustment), latitude, longitude, and time of the power station are input into a known solar radiation model (i.e., the second target model mentioned above) (e.g., the Hay model) at each moment during the possible adjustment period (i.e., the first time period mentioned above), to obtain the total radiation of the tilted surface at each moment after adjustment; similarly, the direct horizontal irradiance, diffuse horizontal irradiance, current tilt angle of the power station (i.e., the tilt angle of the target support before adjustment), latitude, longitude, and time of the power station are input into a known solar radiation model (i.e., the second target model mentioned above) at each moment during the possible adjustment period (i.e., the first time period mentioned above), to obtain the total radiation of the tilted surface at each moment before adjustment;

[0055] Step S208: Determine the target time period based on the total radiation of the inclined surface. The target time period is the second time period within the first time period during which the target support is adjusted. The target support is a device used in the photovoltaic power station to adjust the angle of the photovoltaic panels.

[0056] To maximize the radiation of the adjusted inclined surface, the target time period is determined based on the total radiation of the inclined surface, including the following steps: First, select a second time period within the first time period as the starting adjustment time period. Then, calculate the total radiation of the inclined surface in each second time period within the first time period, based on the total radiation of the inclined surface corresponding to each third time period, when the second time period is the starting adjustment time period. Next, calculate the sum of the total radiation of the inclined surface in each second time period within the first time period, which is the sum of the total radiation of the inclined surface in the first time period when the second time period is the starting adjustment time period. Finally, determine the starting adjustment time period when the sum of the total radiation of the inclined surface in the first time period is the largest and greater than the original sum of the total radiation of the inclined surface. The original sum of the total radiation of the inclined surface is the sum of the total radiation of the inclined surface in the first time period without adjusting the target support.

[0057] This application also comprehensively considers the impact of the adjustment time required when determining the support adjustment time. Specifically, based on the total radiation of the tilted surface corresponding to each third time period, when the second time period is used as the start adjustment time period, the calculation of the total radiation of the tilted surface in each second time period within the first time period includes the following steps: determining the adjustment capacity of each second time period within the first time period, wherein the adjustment capacity is the power value of the photovoltaic power generation device corresponding to the target support that can complete the angle adjustment in each second time period; based on the adjustment capacity, determining the adjusted capacity and unadjusted capacity corresponding to each second time period within the first time period when the second time period is used as the start adjustment time period; and calculating the total radiation of the tilted surface in each second time period based on the adjusted capacity and unadjusted capacity corresponding to each second time period, as well as the total radiation of the tilted surface before adjustment and the total radiation of the tilted surface after adjustment.

[0058] Specifically, assuming that the adjustment of the fixed adjustable support of the power station takes k days, the daily adjustment capacity = total adjustment capacity / k. The daily adjustment capacity is taken as the adjusted capacity from the next day. Then the daily total radiation of the inclined surface = the adjusted total radiation of the inclined surface × the adjusted capacity as of the day / total adjustment capacity + the tilted surface total radiation before adjustment × the unadjusted capacity as of the day / total adjustment capacity. Calculate the total radiation of the inclined surface for each day (i.e., the second time period) within the possible adjustment period (i.e., the first time period mentioned above) as the start date of adjustment (i.e., the start adjustment period mentioned above).

[0059] In addition, it is necessary to calculate the total radiation of the tilted surface during the adjustment period if no adjustment is made (i.e., the original total radiation of the tilted surface mentioned above);

[0060] If a certain day within the possible adjustment period (i.e., the first time period mentioned above) is chosen as the start adjustment day (i.e., the start adjustment time period mentioned above), and the total radiation of the inclined surface within the possible adjustment period is the largest and exceeds the total radiation of the inclined surface calculated under the condition of no adjustment (i.e., the original total radiation of the inclined surface mentioned above), then that day is taken as the actual start adjustment day (i.e., the target time period mentioned above); otherwise, increase n (i.e., the second quantity mentioned above), redetermine the possible adjustment period (i.e., the first time period mentioned above), and repeat the steps of the above stent adjustment time determination method until the actual adjustment day (i.e., the target time period mentioned above) is found.

[0061] The method for determining the stent adjustment time in steps S202 to S208 of the embodiments of this application will be further described below.

[0062] Figure 3 This is a schematic diagram of a method for determining the adjustment date of a fixed adjustable bracket according to an embodiment of this application, as shown below. Figure 3 As shown, the method includes the following steps:

[0063] Step 1: Obtain the total irradiance and scattered irradiance of the power station's horizontal plane through the total irradiance meter and scattered irradiance meter installed at the power station. After the scattered irradiance meter model is trained, choose to remove or retain it according to actual needs.

[0064] Step 2: Using total horizontal irradiance, total horizontal irradiance outside the atmosphere, declination angle, hour angle, total suspended particulate matter in the atmosphere, and relative humidity as input parameters, and horizontal diffuse irradiance as output parameter, establish and train a machine learning model (i.e., the first target model mentioned above). The ratio of horizontal diffuse irradiance to total horizontal irradiance is related to the ratio of total horizontal irradiance to total horizontal irradiance outside the atmosphere, the thickness of sunlight passing through the atmosphere, air quality, and relative humidity. The declination angle and hour angle determine the thickness of sunlight passing through the atmosphere. Total suspended particulate matter in the atmosphere reflects air quality. The total horizontal irradiance outside the atmosphere, declination angle, and hour angle can be calculated based on celestial geometry principles. Total suspended particulate matter in the atmosphere and relative humidity can be obtained from public channels (e.g., historical weather data).

[0065] After the model training is completed, inputting the total horizontal irradiance, the total horizontal irradiance outside the atmosphere, the declination angle, the hour angle, the total suspended particulate matter in the atmosphere, and the relative humidity of the air will yield the horizontal diffuse irradiance.

[0066] Step 3: Calculate the total radiation of the clear sky tilt surface daily (i.e., the second time period above) for each tilt angle according to the principles of celestial geometry. The total radiation of the clear sky tilt surface refers to the total radiation of the tilt surface when there are no clouds in the sky. In this case, solar radiation only includes direct radiation and no scattered radiation.

[0067] Step 4: When the total radiation of the clear sky tilt surface under the two tilt angles is equal or closest on a certain day, that day is determined as the ideal adjustment day (i.e. the above candidate adjustment period).

[0068] Step 5: Obtain the weather forecast for the ideal adjustment date and n days before and after it (i.e., the second quantity mentioned above) (the possible adjustment period, i.e., the first time period mentioned above);

[0069] Step 6: For each day of the possible adjustment period (i.e., the first time period mentioned above), find the total horizontal radiation of all the same weather conditions in the same period of previous years based on the weather forecast data, and use the average value as the total horizontal radiation of that weather type in the possible adjustment period.

[0070] Step 7: Calculate the absolute value of the difference between the total horizontal radiation on each day during the possible adjustment period (i.e., the first time period mentioned above) and the total horizontal radiation on the clear sky on that day, and denot it as a (i.e., the target difference mentioned above).

[0071] Step 8: Calculate the total irradiance of the clear sky at each moment during the possible adjustment period based on the principles of celestial geometry. Randomly select m moments (i.e., the first number mentioned above) during the day (i.e., the random time period mentioned above). Randomly generate an irradiance (i.e., the random irradiance mentioned above) at each moment, such that the integral of the product of the m random irradiances at the m moments and the time resolution is equal to a. Then, the total irradiance of the clear sky at the selected m moments (i.e., the random time period mentioned above) = the total irradiance of the clear sky at that moment - the random irradiance at that moment. The total irradiance of the clear sky at the remaining moments (i.e., the remaining third time period mentioned above) = the total irradiance of the clear sky at that moment.

[0072] Step 9: Input the total horizontal irradiance, total horizontal irradiance outside the atmosphere, declination angle, hour angle, total suspended particulate matter in the atmosphere, and relative humidity of the air at each moment during the possible adjustment period (i.e., the first time period mentioned above) into the model (i.e., the first target model mentioned above) to obtain the horizontal diffuse irradiance at each moment. The horizontal direct irradiance at each moment = the total horizontal irradiance at that moment - the horizontal diffuse irradiance at that moment.

[0073] Step 10: Input the direct horizontal irradiance, diffuse horizontal irradiance, tilt angle to be adjusted of the power station (i.e., the tilt angle of the target support after adjustment), latitude of the power station, longitude of the power station, and time into a known solar radiation model (i.e., the second target model mentioned above) (e.g., the Hay model) at each moment during the possible adjustment period (i.e., the first time period mentioned above) to obtain the total irradiance of the tilted surface at each moment after adjustment; Similarly, input the direct horizontal irradiance, diffuse horizontal irradiance, current tilt angle of the power station (i.e., the tilt angle of the target support before adjustment), latitude of the power station, longitude of the power station, and time into a known solar radiation model (i.e., the second target model mentioned above) at each moment during the possible adjustment period (i.e., the first time period mentioned above), to obtain the total irradiance of the tilted surface at each moment before adjustment;

[0074] Step 11: The adjustment of the fixed adjustable support of the power station requires k days. The daily adjustment capacity = total adjustment capacity / k. The daily adjustment capacity is taken as the adjusted capacity starting from the second day. The daily total radiation of the inclined surface = total radiation of the inclined surface after adjustment × adjusted capacity up to the day / total adjustment capacity + total radiation of the inclined surface before adjustment × unadjusted capacity up to the day / total adjustment capacity. Calculate the total radiation of the inclined surface for each day (i.e., the second time period) within the possible adjustment period (i.e., the first time period mentioned above) as the start date of adjustment (i.e., the start adjustment period mentioned above).

[0075] Step 12: Calculate the total radiation of the inclined surface during the adjustment period if no adjustment is made (i.e., the original total radiation of the inclined surface mentioned above);

[0076] Step 13: If a certain day within the possible adjustment period (i.e., the first time period mentioned above) is taken as the start adjustment day (i.e., the start adjustment time period mentioned above), and the total radiation of the inclined surface during the possible adjustment period is the largest and exceeds the total radiation of the inclined surface calculated under the condition of no adjustment (i.e., the original total radiation of the inclined surface mentioned above), then that day is taken as the actual start adjustment day (i.e., the target time period mentioned above); otherwise, increase n (i.e., the second quantity mentioned above) and repeat the steps starting from step 5 until the actual adjustment day (i.e., the target time period mentioned above) is found.

[0077] By combining the above steps with future weather conditions and calculating the optimal adjustment date based on the principle of maximizing the radiation of the tilted surface after adjustment, the goal of maximizing the power generation benefits brought by the fixed adjustable support is achieved. This solves the technical problem of poor power generation efficiency of photovoltaic power plants caused by related technologies that only calculate the adjustment month based on the average radiation of the tilted surface, randomly select the support adjustment time in that month, and do not consider the influence of weather factors.
