Topology Conditioned Physics Informed Graph Surrogates for AC Optimal Power Flow Under Line Outages

Security assessment requires repeated alternating current optimal power flow (AC OPF) solutions under changing injections and line outages. We propose a topology conditioned physics informed graph Fourier neural operator (GFNO PINO) that predicts voltage phasors and dispatch from network and operating data. Chebyshev f...
