# GENCO: A Unified Neural Solver and Development Framework for Steady-State Grid Analysis

## AI commentary

> This paper is worth attention for AI practitioners in power systems, showing that neural solvers can balance speed and reliability under strict physical consistency constraints. For large-scale grid operators and research teams building power foundation models, GENCO's unified architecture and open toolchain may significantly reduce experimentation costs.

## At a glance

GENCO (Geometric Neural Corrective Optimizer) is a unified neural solver that handles power flow, optimal power flow, and state estimation within a single architecture and shared network representation. The accompanying open-source GridFM Development Framework standardizes low-code synthetic data generation and training, with large-scale datasets covering millions of PF/OPF scenarios across diverse grid topologies. In benchmarks, GENCO recovers full AC operating states for large-scale PF while achieving up to 30x speedups over Newton-Raphson at only 2x the runtime of DC-PF. For OPF, it achieves up to 85x speedups over IPOPT with improved feasibility and optimality. For SE, GENCO is more robust than weighted least squares to noisy measurements and parameter errors. This lowers the entry barrier for power system engineers and marks a step toward Grid Foundation Models.

## Key points

- GENCO solves power flow, optimal power flow, and state estimation with a unified architecture and shared network representation.
- GridFM Development Framework enables low-code synthetic data generation and training, with open datasets of millions of scenarios.
- Up to 30x speedup over Newton-Raphson for large-scale PF with full AC state recovery; up to 85x speedup over IPOPT for OPF with better feasibility and optimality.
- SE is more robust than weighted least squares to noise and parameter errors, providing high-quality estimates even when WLS fails to converge.

## Full text

Foundation models are transforming business workflows and boosting productivity, yet they remain largely absent from engineering domains such as power system analysis, where strict physical consistency must be enforced. We present GENCO (GEometric Neural Corrective Optimizer), a unified neural solver for steady-state transmission grid analysis that handles power flow (PF), optimal power flow (OPF), and state estimation (SE) within a single architecture and shared network representation. To support advances in neural power system solvers, we introduce the open-source GridFM Development Framework, which standardizes synthetic data generation and training in a low-code environment. We also release large-scale datasets with millions of PF and OPF scenarios across diverse grid topologies to support reproducible benchmarking. We evaluate GENCO on the PFDelta and OPFData benchmarks against state-of-the-art neural solvers and classical solvers, including Newton-Raphson and IPOPT, as well as on real-world Hydro-Québec SCADA data. For large-scale PF, GENCO recovers the full AC operating state, including voltage magnitudes and reactive power that DC-PF cannot provide, while matching DC-PF-level active power-balance residuals. It achieves up to 30x speedups over Newton-Raphson at only 2x the runtime of DC-PF. For OPF, it achieves up to 85x speedups over IPOPT while improving feasibility, optimality, and runtime over DC-OPF. For SE, GENCO is more robust than classical weighted least squares to noisy measurements and network parameter errors, and always returns a high-quality estimate even when weighted least squares fails to converge. Together, the unified architecture and development framework provide a new approach to large-scale steady-state grid analysis, lowering the barrier to entry for power system engineers and marking a step toward Grid Foundation Models.
