Cloud transient characterization in different time steps
(American Institute of Physics Inc., 2017-06)
In this paper we evaluate the cloud transients by analyzing the dynamics of the direct fraction index kb for one year of solar radiation data in different time steps. We use instant 5-sec data integrated data and compare ...

A normalized variability index of daily solar radiation
(American Institute of Physics Inc., 2020-12)
The Variability Index (VI) is widely used to quantify the intra-day solar radiation variability. It compares the length of the global horizontal irradiance (GHI) or direct normal irradiance (DNI) profiles with the length ...

Impact of the intra-day variability of the DNI on the energy yield of CSP plants
(American Institute of Physics Inc., 2019-07)
The operation and the electricity yield of CSP plants in two days with the same daily-accumulated DNI, even with the same Aperture Normal Irradiance (ANI) can be very different depending on other parameters such as the ...

An improved model for the synthetic generation of high temporal resolution direct normal irradiation time series
(Elsevier, 2015-12)
Several studies have confirmed the relevant impact of the resolution and frequency distribution of solar radiation data on the results of detailed production models. Many of the available direct normal irradiance (DNI) ...

Visual Resources for Learning Thermodynamics: A Neuroeducation Perspective
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)
Thermodynamics is an engineering subject that is particularly difficult to teach and learn because it requires strong abstract theoretical concepts and extensive multidisciplinary knowledge. This manuscript introduces ...

Analysis of the distribution of measured and synthetic DNI databases and its effect on the expected production of a parabolic trough plant
(Elsevier, 2014)
The generation of a Typical Meteorological Year (TMY) is a common practice in solar energy projects. Therefore it is desirable that the TMY provides not only a good estimate of the solar resource in the long term, but also ...

Synthetic generation of plausible solar years for long-term forecasting of solar radiation
(Springer, 2022-08)
In this work, we test and improve an algorithm proposed in previous studies to generate synthetic series of plausible solar years (PSY). The method provides 100 synthetic years of coupled global horizontal irradiance (GHI) ...
