Quantifying PV power Output Variability
Thomas E. Hoff,Richard Perez +1 more
TL;DR: In this paper, the relative power output variability for a fleet of identical PV systems (same size, orientation, and spacing) can be quantified by identifying the number of PV systems and their Dispersion Factor, which captures the relationship between PV fleet configuration, Cloud Transit Speed, and the time interval over which variability is evaluated.

High-frequency irradiance fluctuations and geographic smoothing
TL;DR: Lave et al. as mentioned in this paper applied a wavelet transform to both the clear-sky index at one site and the average of six sites to estimate the smoothing of aggregated power output due to geographic dispersion in a distribution feeder.

Classification of daily solar radiation distributions using a mixture of Dirichlet distributions
TL;DR: In this article, the authors classify daily distributions of the clearness index kt by estimating a finite mixture of Dirichlet distributions without assuming any parametric hypothesis on these daily distributions.

The interrelationship and characteristic distribution of direct, diffuse and total solar radiation
TL;DR: In this paper, the authors present relationships permitting the determination on a horizontal surface of the instantaneous intensity of diffuse radiation on clear days, the long term average hourly and daily sums of diffuse radii, and the daily sum of diffuse radiata for various categories of days of differing degrees of cloudiness.

The average distribution of solar radiation-correlations between diffuse and hemispherical and between daily and hourly insolation values
Manuel Collares-Pereira,Ari Rabl +1 more
TL;DR: In this article, the correlations of Hottel, Whillier, Liu and Jordan between diffuse and hemispherical, and between instantaneous (hourly) values and daily totals of solar radiation are recalibrated against pyrheliometer data for five stations in the U.S.

The long-term average performance of flat-plate solar-energy collectors
TL;DR: The flat-plate collectors have been used successfully for many years in the southern United States and elsewhere as water heaters, and potentially can be used for space heating, drying, refrigeration, power generation and similar purposes as discussed by the authors.

Simple procedure for generating sequences of daily radiation values using a library of Markov transition matrices
TL;DR: In this article, the authors describe how sequences of daily global radiation can be generated for any location, using as input only the average monthly radiation for that location (or the average month number of sunshine hours) using a library of Markov transition matrices, each corresponding to a specific interval in Kt.

The frequency distribution of daily insolation values
TL;DR: In this article, the frequency distribution of daily total hemispherical solar irradiation values on the horizontal surface is derived from measured data for 90 locations in the U.S. The results can be approximated by generalized distribution curves which depend only on the clearness index, defined as ratio of terrestrial over extraterrestrial insolation.
