How predictable is DNI? An evaluation of hour ahead and day ahead DNI forecasts from four different providers
Forecast DNI values in hourly resolution for one day ahead are evaluated by a comparison with pyrheliometer ground measurements. Three months of such day ahead forecasts from four different providers for a site close to Questa, NM, USA are analyzed firstly by calculating the RMSE and the mean bias error. Secondly, cumulative distributions of the DNI forecast errors are calculated as they better...
متن کاملDifferentiating DNI from DNR: combating code status conflation.
Goals of care discussions, including those focused on code status, are meant to foster autonomous decision making. Unfortunately, these discussions often conflate decisions regarding the use of cardiopulmonary resuscitation for cardiac arrest and mechanical ventilation for prearrest respiratory failure. They also exclude discussions of outcomes, particularly those associated with prearrest resp...
متن کاملReal-time prediction intervals for intra-hour DNI forecasts
We develop a hybrid, real-time solar forecasting computational model to construct prediction intervals (PIs) of one-minute averaged direct normal irradiance for four intra-hour forecasting horizons: five, ten, fifteen, and 20 min. This hybrid model, which integrates sky imaging techniques, support vector machine and artificial neural network sub-models, is developed using one year of co-located...
متن کاملSun-tracking imaging system for intra-hour DNI forecasts
A Sun-tracking imaging system is implemented for minimizing circumsolar image distortion for improved short-term solar irradiance forecasts. This sky-imaging system consists of a fisheye digital camera mounted on an automatic solar tracker that follows the diurnal pattern of the Sun. The Sun is located at the geometric center of the sky images where the fisheye distortion is minimized. Images f...
متن کاملAtmospheric Attenuation in Central Receiver Systems from Dni Measurements
Atmospheric attenuation loss between the heliostat field and receiver has been recognized as a significant source of loss in Central Receiver System. Methods that can improve estimation of attenuation loss using available measurements will be useful in reducing uncertainty in estimation of CSP plant production, particularly in locations and climates that differ in atmospheric composition from t...
