New study questions advection-aware GNNs for solar ramp forecasting

A new study published on arXiv investigates the effectiveness of advection-aware graph neural networks (GNNs) for forecasting solar power ramps. The research found that while connecting sites based on cloud motion vectors (CMVs) did not outperform simpler GNNs, providing accurate motion vectors as input features significantly improved predictions. The study also introduced a self-supervised cloud-motion estimator that achieved better results than traditional cross-correlation methods, closing a substantial portion of the performance gap for solar ramp forecasting.

    When Does Advection-Aware Graph Nowcasting Help? A Controlled Study of Distributed Solar Ramp Forecasting with a Self-Supervised Cloud-Motion Estimator

    arXiv:2609.30286v1 Announce Type: cross Abstract: Short-term forecasting of cloud-induced power ramps across a network of distributed photovoltaic (PV) or irradiance sensors is a recognised pain point for grid operators. A natural idea is to make the graph neural network (GNN) ad…
