WP4: Weather forecasting and measurement for renewable energy predictability
Traditionally, Numerical Weather Prediction (NWP) models have not included in their forecasts the direct solar irradiance, a key variable for the Concentrating Solar Power (CSP) industry. As NWP models are constantly improving, this situation has changed during the past few years, and nowadays many models forecast this parameter. In particular, the two main high resolution models used by AEMET - the global model Integrated Forecast System (IFS), developed by the European Centre for Medium-Range Weather Forecasts (ECMWF), and the mesoscale model Harmonie (Hirlam Aladin Regional/Meso-scale Operational NWP In Europe), already forecast the direct horizontal irradiance, as well as the global horizontal irradiance. The objective of this work is to verify the forecasts from both models (IFS and Harmonie) against observations measured by the AEMET radiation network, composed by several stations distributed over Spain, and to improve their accuracy by means of post-processing techniques.
