A Benchmark Graph Dataset for Transient Stability Assessment of the IEEE 9-Bus System: 20,000 Scenarios with Full Generator Trajectories
Hussein Suprême, Martin de Montigny, Arnaud Zinflou
Transient stability assessment determines whether a power system retains synchronism after a large disturbance. Machine-learning surrogates can accelerate it, but progress is limit…
SPLICE: Latent Diffusion over JEPA Embeddings for Conformal Time-Series Inpainting
Arnaud Zinflou
Long gaps in time series are difficult to reconstruct reliably, and in power systems imputed load values inform dispatch and planning. Existing generative imputers are accurate but…
STEMS: Spatial-Temporal Enhanced Safe Multi-Agent Coordination for Building Energy Management
Huiliang Zhang, Di Wu, Arnaud Zinflou +1
Building energy management is essential for achieving carbon reduction goals, improving occupant comfort, and reducing energy costs. Coordinated building energy management faces cr…
Leveraging Multivariate Long-Term History Representation for Time Series Forecasting
Huiliang Zhang, Di Wu, Arnaud Zinflou +3
Multivariate Time Series (MTS) forecasting has a wide range of applications in both industry and academia. Recent advances in Spatial-Temporal Graph Neural Network (STGNN) have ach…
MXMap: A Multivariate Cross Mapping Framework for Causal Discovery in Dynamical Systems
Elise Zhang, François Mirallès, Raphaël Rousseau-Rizzi +3
Convergent Cross Mapping (CCM) is a powerful method for detecting causality in coupled nonlinear dynamical systems, providing a model-free approach to capture dynamic causal intera…
