Integrating Physics-Informed Neural Networks into Power System Dynamic Simulations

1 code implementation20 Apr 2024 Ignasi Ventura Nadal, Jochen Stiasny, Spyros Chatzivasileiadis

This paper introduces the first natural step to remove the barriers for using PINNs in time-domain simulations: it proposes the first method to integrate PINNs in conventional numerical solvers.

Scalable Bilevel Optimization for Generating Maximally Representative OPF Datasets

1 code implementation21 Apr 2023 Ignasi Ventura Nadal, Samuel Chevalier

However, generating training datasets that accurately represent the many possible combinations of these active constraints is a particularly challenging task, especially within the realm of nonlinear AC Optimal Power Flow (OPF), since most active constraints cannot be enforced explicitly.
