Ensemble Nonlinear Autoregressive Exogenous Artificial Neural Networks for Short-Term Wind Speed and Power Forecasting

Figure 12

Out-of-sample multi-step-ahead ensemble forecasts of the wind power for the cases when the CFD and BI wind speed data were used as exogenous inputs. The dashed lines marked with circles delineate the 95% confidence intervals for the ensemble wind power prediction using the CFD data. The predictions were obtained using a NARX ANN model structure.
