Deterministic wind power forecasts enclose an inherent uncertainty due to several sources of error.In order to counterbalance this deficiency, an analysis of the error characteristics and construction of probabilistic forecasts with associated confidence levels is necessary for the quantification of the corresponding uncertainty.This work proposes a probabilistic forecasting method using an atmospheric Spring model, optimization techniques for addressing the temporal error dependencies and Kalman filtering for eliminating systematic errors AEG HKB75NB540 75cm Five Burner Gas-on-glass Hob With Work Burner and enhancing the symmetry-normality of the shaped error distributions.The method is applied in case studies, using real time data from four wind farms in Greece.The performance is compared against a reference method as well as other common methods showing an improvement in the predictive reliability.
