چکیده انگلیسی
This Brief Note presents a general and efficient clustered-based methodology for the generation of high-frequency coupled global horizontal irradiance (GHI) and direct normal irradiance (DNI) series, based on the envelope clear sky and Dynamic Paths concepts. The procedure for generating 1-min synthetic irradiance data assumes that the effect of passing clouds on the fluctuations of both GHI and DNI can be dynamically reproduced using local variability patterns characterized by a 1-year ground measurements. This work presents for the first time synthetically generated 1-min GHI and DNI coupled datasets (156â¯months, from 1999 to 2011) generated from their corresponding low frequency series and local solar irradiance dynamics. The statistical parameters used for compare the measured and generated series perform well: mean absolute deviation is negligible, with averaged values of â¼0.3% and â¼0.2% for GHI and DNI, respectively. The KSI(%) values for DNI and GHI are lower than 100% in average. KSI(%) values of GHI series (in the range of 51.5-70.1% for averaged daily KSI(%) values at each month) are lower than the respective KSI(%) values of the DNI series (in the range of 75.0-110.8%). Finally, the generated 1-min solar irradiance series has the same autocorrelative structure as the observed, according to the similitude of their Ramp Rates.
