| Abstract | The fast increase in importance of the solar energy resource as viable and promising source of renewable energy has boosted research in methods to evaluate the short-term forecasts of the solar energy resource. There is an increasing demand from the energy sector for accurate forecasts of solar energy resources in order to support the planning and management of the electricity generation and distribution systems. The Eta model that runs operationally in the Brazilian Center of Weather Forecast and Climate Studies (CPTEC/INPE) has outputs for solar radiation flux at the surface. However, these radiation forecasts are greatly overestimated. In order to achieve more reliable short-term estimates for the downward solar radiation flux at the surface, forecasts for the future atmospheric conditions provided by Eta/CPTEC model were used as inputs in Artificial Neural Networks (ANNs). Ground data of downward solar radiation flux acquired in two SONDA sites located in south Brazil (Florianópolis and São Martinho da Serra) were used for ANNs training and for forecasts evaluation. The forecasts from ANNs have presented higher correlation coefficients and lower deviations than the model Eta/CPTEC output. The bias observed in solar radiation forecasts provided by the Eta/CPTEC model was removed by the ANNs. The improvement in RMSE obtained with ANNs over the model Eta/CPTEC was higher than 30%. |
