Wind speed and wind energy forecast through Kalman filtering of Numerical Weather Prediction model output

► NWP models are unable to provide reliable wind speed forecast in complex terrain. ► Kalman filtering techniques are widely used to improve the prediction of NWP models. ► Kalman filter is tuned to find the most suitable configuration to predict wind speed. ► The filter is applied to forecast wind speed and wind power at a wind farm site. ► Simulations, corrected by Kalman filtering, show very low errors wrt measurements.
