Nwp correction

WebAbstract:Numerical Weather Prediction (NWP) is the key to precise wind power forecasting (WPF), which can be enhanced by the NWP correction and scenario partition techniques. However, on the one hand, existing NWP correction techniques may enlarge the volatility of ensemble NWP which disturbs the subsequent WPF. Web18 nov. 2024 · MOS uses a multiple linear regression to correct systematic errors in NWP models using NWP outputs of certain weather variables as predictors and fitting these predictors to observations. To find the optimal predictors, the MOS multivariate regression equations are used.
