Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

in step S120, solar radiation irradiance on sunny days is calculated according to the basic data;
in step S130, a cloud-sky parameterized model is established, and the cloud-sky parameterized model is used to calculate the cloud-sky solar irradiance according to the calculated sunny-day solar irradiance.
In this embodiment, the time parameter in step S110 includes an estimated time interval and a time zone of the area to be measured, where the estimated time interval is calculated according to the local time of the area to be measured; the geographic factors comprise longitude, latitude, altitude, height of a light receiving surface from the ground and ground surface albedo of the area to be detected; the atmospheric condition factors comprise the ground hourly air temperature, the relative humidity, the atmospheric pressure, the daily average temperature and the seasons of the area to be detected, wherein the seasons are divided into summer half years and winter half years; the solar radiation influence factors are specifically divided into sunny solar radiation influence factors and cloud solar radiation influence factors, wherein the sunny solar radiation influence factors comprise water vapor parameters, ozone parameters, gas pollutant parameters, carbon dioxide and aerosol parameters, and the cloud solar radiation influence factors comprise total cloud amount, cloud type, cloud optical thickness and the like.
In the present embodiment, the basic data includes a time parameter, a geographical factor, an atmospheric condition factor, and a solar radiation influence factor, which have been subjected to parameterization processing. The time parameter, the geographic factor and the atmospheric condition factor can be obtained by observing through a ground meteorological station, and the solar radiation influence factor can be obtained by satellite remote sensing.
It should be further noted that, in practical applications, the space-time resolution of the ground solar radiation may be set according to requirements of different projects, and the space-time resolution specifically includes a time resolution and a space resolution. For example, the spatial resolution of terrestrial solar radiation is set to 10km and the temporal resolution to hours based on the scale of a large solar power project. When evaluating the solar radiation of a certain area a, the area a is first divided into grids according to the spatial resolution, and the region to be measured in step S110 is the region represented by one divided grid, for example, when the spatial resolution is 10km, the region to be measured is a grid region with a side length of 10km in the area a. And after the gridding division is carried out, acquiring time parameters, geographic factors, atmospheric state factors and solar radiation influence factors of the gridded divided grid points as basic data of the area to be measured.
In this embodiment, the sunny solar radiation irradiance in step S120 refers to the irradiance of the solar radiation obtained without considering the influence of the cloud in the atmosphere on the solar radiation. Therefore, in step S130, considering the influence of the cloud on the solar radiation, a cloud-sky parameterized model is established using the cloud amount, the cloud type, the cloud optical thickness, and the like as solar radiation influence factors, and the cloud-sky solar radiation irradiance is calculated on the basis of the clear-sky solar radiation irradiance calculated in step S120, so as to obtain the ground solar radiation under the actual meteorological conditions.
As described above, in the present embodiment, before solar energy resource evaluation, a space-time resolution needs to be determined, and 24 hours a day is divided into a plurality of time intervals according to the determined time resolution; and then calculating the average solar irradiance of each time interval by the evaluation method provided by the embodiment. For example, when the determined time resolution is 1 hour, 24 hours a day is divided into 24 intervals with the length of 1 hour, and the cloud-day solar irradiance calculated by the evaluation method is the average cloud-day solar irradiance in hours. On the basis of calculating the cloud solar irradiance of each time interval, the solar radiation daily irradiance, the monthly irradiance and the annual irradiance can be further calculated.
The solar energy resource assessment method provided by the embodiment comprehensively considers factors such as time parameters, geographic factors, atmospheric state factors and solar radiation influence factors influencing solar radiation, establishes a calculation model to calculate the solar radiation irradiance in a clear day, calculates the solar radiation irradiance in a cloud day based on the calculated solar radiation irradiance in the clear day, thereby obtaining the ground solar radiation under the actual meteorological condition, further calculates the solar radiation daily exposure, the monthly exposure and the annual exposure, can finely calculate and assess the solar energy resources of the region to be tested, and further provides basic data and scientific basis for formulation of solar energy development and utilization planning, site selection and design of a solar power station, full utilization of the solar energy resources and the like.
In this embodiment, the sunny solar radiation irradiance refers to irradiance of total sunny solar radiation of the area to be measured, and the cloud solar radiation irradiance refers to irradiance of total cloud solar radiation of the area to be measured. It should be noted that the total solar radiation includes both direct solar radiation and scattered solar radiation. Direct solar radiation refers to radiation that the sun projects directly onto the ground in parallel rays; the solar scattered radiation refers to a part of solar radiation which reaches the earth surface from various angles of the sky under the scattering action of gas, dust, aerosol and the like in the atmosphere when the solar radiation passes through the atmosphere; the total solar radiation is the sum of the direct solar radiation and the scattered solar radiation received at a certain observation point level on the earth surface.
Correspondingly, in the embodiment, when the cloud-day solar radiation irradiance is calculated, the cloud-day direct radiation irradiance and the cloud-day scattered radiation irradiance are respectively calculated, and the cloud-day solar radiation irradiance is further calculated according to the calculated cloud-day direct radiation irradiance and the calculated cloud-day scattered radiation irradiance.

wherein n represents a cloud type, cnEmpirical coefficients for corresponding cloud types, CFnFor cloud cover threshold corresponding to cloud type, DNI2 is cloud normal direct irradiance, and DNI1 is clear normal direct irradiance.
It should be noted that, in practical application, c is obtained by fitting the statistical relationship between the normal direct radiation of the ground actual measurement and the direct radiation of the satellite inversion in sunny days and the cloud amountn and CFn。

It should be noted that in practical application, a is obtained by fitting a statistical relationship among the chronologically horizontal plane direct radiation, the scattering radiation, the horizontal plane total radiation and the extraterrestrial solar radiation irradiance measured on the ground1、a2、a3、a4、a5. Further, in the formula (3), kTThe statistical relationship among the chronologically horizontal plane direct radiation, the scattered radiation, the horizontal plane total radiation and the extraterrestrial solar radiation irradiance of the segmented interval ground actual measurement is adjusted, and is not limited to k in the formula (3)TThe segment interval of (2).
As an alternative implementation, in step S134, the cloud solar irradiance GHI2 is calculated by formula (4):
GHI2＝DBI2+DHI2 (4)
as mentioned above, the clear sky index k is used in the process of calculating the solar irradiance in the cloudT. In practical application, the clear sky index k is calculated by adopting an empirical calculation model based on the clear sky indexTAnd calculating k using equation (5)T：
Wherein EI is the extraterrestrial solar irradiance.
As an alternative embodiment, in step S120, the solar radiation irradiance on sunny days is calculated using smart mode.
The smart Mode refers to a solar radiation transmission Mode (smart, Simple Mode for an tomo-spectral transmission of sunlight), and is a spectral Mode based on Fortran language, and can calculate and estimate the direct sunlight, scattering and total solar irradiance incident on any plane of the earth surface. Smart is capable of computationally processing solar radiation covering the entire short wave band, visible band, near infrared band of the solar spectrum.
