MxGPS: Multiplex Graph Transformers for a Power Grid Foundation Model

Charilaos Papaioannou, Ioannis Tsantilas, Dimitris Giannakakos +9

The paper presents MxGPS, a multiplex graph transformer that jointly trains on static state estimation and AC power flow to avoid topology overfitting, achieving robust zero‑shot p…
