Researchers have investigated the impact of scale on physics-aware surrogate models for AC optimal power flow (ACOPF). By sweeping through various model and dataset sizes, they found that both Mean Squared Error (MSE) and Augmented Lagrangian (AL) objectives improve with scale following power laws, but at different rates. The AL objective showed a significant reduction in constraint violation compared to MSE, achieving nearly 30x improvement for a comparable increase in training time and negligible memory overhead. This suggests that the choice of training objective critically influences how a surrogate model's quality evolves with increasing scale. AI
