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 ...

Comparison of the representativeness of solar radiation type of days from the viewpoint of the production of parabolic trough and central receiver plants
(American Institute of Physics, 2022-05)
The classification of days according to the solar radiation features is one of the tools frequently used for the solar resource assessment, modelling or forecasting. Recent studies discuss the appropriate classification ...

Identifying periods of clear sky direct normal irradiance
(Elsevier, 2017)
When modeling the effect of the cloud transients in the Direct Normal Insolation (DNI), it is particularly relevant to identify those moments in which there are no clouds between the observer and the sun. In this paper, ...

Process Heat Generation Potential from Solar Concentration Technologies in Latin America: The Case of Argentina
(MDPI, 2017-03-17)
This paper evaluates the potential of solar concentration technologies—compound parabolic collector (CPC), linear Fresnel collector (LFC) and parabolic trough collector (PTC)—as an alternative to conventional sources of ...

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) ...

Direct radiation estimates from horizontal global irradiance values
(EDP Sciences, 1999)
One of the main factors determining the economic feasibility of a solar thermal power plant is the availability of direct radiation at the plant site. During last years, two Central Receiver Power Plants (Solgas and Colon ...

Assessment of a Global-to-Direct empirical model for the long-term characterization of Direct Normal Insolation
(Elsevier, 2014)
The statistical characterization of the solar resource (direct normal solar radiation) is a key point in the initial phases of a solar thermal electricity (STE) plant project. Ideally, this characterization should be based ...

The variable geometry central receiver system concept. First results and comparison with conventional central receiver systems
(Elsevier, 2014)
In line with the global trend for improving efficiency of existing solar power plants, the CTAER has developed and built a variable geometry central receiver facility, in which the solar field rotates around the tower ...

Thermodynamic Limits of the Use of PCM Simultaneously in Photovoltaic Modules and in Building
(EUPVCEC, 2013)
The paper quantifies the thermodynamic limits on the energy and exergy use that would result from the use of PCM in photovoltaic BIPV modules versus not using PCM, by limiting module temperature to 298 K and the thermal energy ...

Minimizing the Computational Effort to Optimize Solar Concentrators with the Open-Source Tools SunPATH and Tonatiuh++
(MDPI AG, 2021)
Integrals that are of interest in the analysis, design, and optimization of concentrating solar thermal systems (CST), such as the annual optical efficiency of the light collection and concentration (LCC) subsystem, can ...
