Towards GridFM: GENCO – a Unified Neural Solver for Steady-stat...
summary
GENCO is a GNN-based neural solver that unifies AC power flow, AC optimal power flow and state estimation by representing the grid as a heterogeneous graph and iteratively correcting decoded decision variables with explicit power-balance residuals. Reported results: residuals <1% apparent power for AC‑PF, OPF optimality gaps ≈0.3% and feasibility violations ≈0.35%, 5× AC‑PF and 200× AC‑OPF speedups on GPU vs multi‑core CPU, generalization to n−20 contingencies, and a public stack including gridfm-datakit and gridfm-graphkit plus benchmarks.
