Scalable Heterogeneous Graph Foundation Models for Data-Driven Optimal Power Flow in Smart Grids
arXiv:2605.23194v1 Announce Type: new Abstract: Fast and reliable optimal power flow (OPF) approximation is essential for reliable smart-grid operation, yet many learning-based surrogates either flatten the native heterogeneous structure of power networks, target a limited set of grid topologies, or lack scalable infrastructure for graph foundation model (GFM) training. This paper presents a scalable heterogeneous graph neural network (GNN) workflow, built on HydraGNN, for data-driven OPF surrogate modeling and OPF-GFM development. The workflow preserves the distinct node and edge types of pow
The increasing complexity and demands on smart grids, coupled with advancements in heterogeneous graph neural networks, are driving the need for more efficient and robust optimal power flow solutions.
This development can significantly enhance the stability and efficiency of electrical grids, directly impacting energy supply and supporting the growing demands of compute infrastructure.
The ability to rapidly and reliably approximate optimal power flow with AI without flattening network structures improves grid management, enabling more dynamic and resilient energy systems.
