Demand and residual demand modelling using quantile regression

Do, Linh Phuong Catherine et al. 

Residual demand, the difference between demand and solar and wind production, is an important variable in predicting the future price and storage requirements. However, little is known about predicting the residual demand itself as well as its quantiles. Therefore, we model both demand and residual ...

Anti-reflection coated spectrally selective carbon nanotube solar absorbers

Chen, Zhonghua et al. 

Multi-walled carbon nanotube (MWCNT) solar absorbers on aluminium substrates have been prepared by electrophoresis. The MWCNT absorbers exhibit a good spectral selectivity over the visible and infrared wavelengths. However, to further enhance the solar absorption, an anti-reflection coating made ...

Feasibility study of a hybrid plants (photovoltaic–LPG generator) system for rural electrification

Adouane, Mabrouk et al. 

The present study investigates the possibility of using a stand-alone photovoltaic/LPG (liquid petroleum gas) generator hybrid power system for low-cost electricity production which can satisfy the energy load requirements of a typical remote and isolated rural area. In this context, the optimal ...

Quantum mechanical effects analysis of nanostructured solar cell models

Badea, Andrei et al. 

The quantum mechanical effects resulted from the inclusion of nanostructures, represented by quantum wells and quantum dots, in the i-layer of an intermediate band solar cell will be analyzed. We will discuss the role of these specific nanostructures in the increasing of the solar cells efficiency. ...

Dynamic thermal performance analysis of two solar air collectors with and without porous media

Abed, Qahtan A. et al. 

The paper presents the thermal performance comparison between two types of solar air collectors, with and without porous absorber material. In order to simulate the transient processes which occur in the collectors two mathematical models were developed. Each model consists of a set of time ...

Renewable energies – Future perspectives

Vitale, Gianpaolo 

The Global Energy Scenario is analyzed starting from a global energy consumption still sustained by fossil sources. Comparing the time to reach as much as the 50% of the market share of traditional sources with the trend of renewable ones, it appears that this growth is too slow taking into account ...

Cross flow water turbines: HARVEST technology

Achard, Jean-Luc et al. 

This paper describes all the main features of the hydrokinetic devices developed during the HARVEST program. Such devices, which eliminate the well-known weaknesses of Darrieus turbines, are composed of two counter-rotating twin columns of cross flow water turbines (CFWT) built in a support ...

Influence of the side-by-side arrangement on the performance of a small Savonius wind turbine

Jang, Choon-Man et al. 

Scaled-down Savonius turbine rotors arrayed side-by-side are introduced to analyze the effects of design parameters on the performance between turbine rotors. Unsteady flow simulation and experimental measurement have been performed to compare turbine performance and validate the numerical ...

Socioeconomic, environmental and social impacts of a concentrated solar power energy project in Northern Chile

Rodríguez-Serrano, Irene et al. 

Concentrated solar power deployment could potentially play an important role in the sustainable development strategy of Chile, the country with the highest solar potential in the world. Using an Input-Output methodology, this work conducts a sustainability assessment of the installation, operation ...
