A new research paper explores the complexity of ensemble models used in photovoltaic forecasting. The study analyzes how adding components to an ensemble can improve predictions while also potentially increasing computational load or contributing little to the overall accuracy. Experiments using the GEFCom2014 dataset and other public datasets, with retrospective ERA5 assistance, showed that static fusion reduced scaled mean absolute error compared to matched boosting on specific datasets, though not all improvements were statistically significant after correction. The research also found that weather gating did not consistently offer additional benefits, and exploratory removals of model components indicated both group-level dependence and individual redundancy, suggesting the need for component-wise evaluation.
