This wind power forecasting system includes high-resolution and ensemble modeling capabilities, data assimilation, now-casting and statistical post-processing technologies. The system uses publicly available model data and observations as well as wind forecasts produced from an National Center for Atmospheric (NCAR)-developed deterministic mesoscale wind forecast model with real-time four-dimensional data assimilation and a 30-member model ensemble system, which is calibrated using an Analogue Ensemble Kalman Filter and Quantile Regression.
