Clear-sky direct normal irradiance estimation based on adjustable inputs and error correction

Journal of Renewable and Sustainable Energy, 2019
The accurate estimation of direct normal irradiance (DNI) under clear sky conditions plays an important role in the concentrated solar thermal plant. A hybrid model with adjustable inputs is proposed to calculate the clear-sky DNI, including a base clear-

Daily Direct Normal Irradiance Forecasting by Support Vector Regression Case Study: in Ghardaia-Algeria

International Conference on Advances in Electrical Engineering, 2019
Concentrated solar thermal plants (CST) generate electricity from the direct normal irradiance (DNI) component of solar irradiance. Accuracy forecasting of DNI can reduce the uncertainty of solar power plant output caused by solar irradiance ...

Calibration of direct normal irradiance (DNI) forecasts with quantile regression

2020
<p>Direct normal irradiance (DNI) forecasts from two ensemble models, the global ECMWF-ENS and the limited area multimodel gSREPS, have been calibrated using the quantile regression method, taking DNI as the only input parameter to better understand the inner workings of the method.

Turbidity coefficients from normal direct solar irradiance in Central Spain

Atmospheric Research, 2014
Abstract Atmospheric turbidity causes attenuation of solar radiation reaching the earth's surface under a cloudless sky. The Angstrom turbidity coefficient and the aerosol optical thickness, AOD550, were obtained from 10-minute direct normal solar irradiance measurements recorded in a rural area of Castilla y Leon region, Spain, from July 2010 to ...
