New method decomposes wind power forecast uncertainty

Researchers have developed a new method to decompose uncertainty in wind power forecasting into its epistemic and aleatoric components. This approach uses Bayesian posterior approximation and heteroscedastic neural network regression to distinguish between uncertainty from data noise and uncertainty from model limitations. The proposed evaluation framework includes synthetic experiments, real-world data analysis, and scaling studies to validate the decomposition's accuracy and practical utility. AI

    A Posterior-Predictive Variance Decomposition for Epistemic and Aleatoric Uncertainty in Wind Power Forecasting

    arXiv:2605.22390v1 Announce Type: new Abstract: Accurate wind power forecasting requires reliable uncertainty quantification, yet most existing methods report a single predictive uncertainty that conflates epistemic and aleatoric sources. This paper applies the law of total varia…
