EuroSun 2026: Task-aware Latent-Space Coupling for Generative Solar Forecasting

Kurzfassung

FarSky is a generative solar irradiance forecasting framework that uses task-aware latent representations and latent diffusion to generate probabilistic forecasts from all-sky images. Evaluated on multiple datasets, it outperforms persistence, end-to-end, and existing generative methods, improving forecast skill by up to 11 percentage points. It also enhances ramp-event detection, achieving F1-scores above 60%, demonstrating the potential of generative latent-space modeling for accurate solar forecasting.
