How suboptimal is my stochastic network controller allowed to be? Completion certificates with application to power grids hosting AI data centers
Michael Chertkov
Power grids are beginning to host AI data centers whose demand can change abruptly and in a correlated way, and operators and planners must decide whether existing controllers can…
When Gigawatts of Computational Load Disappear: Cycle-Space Certificates for Grid Synchronization and Transient Stability
Michael Chertkov
Rapid growth of data centers and artificial-intelligence services is producing computational loads at scales once associated mainly with largest power plants. Recent grid events sh…
Real-Time Dynamic N-1 Screening: Identifying High-Risk Lines and Transformers After Common Faults
Ayrton Almada, Laurent Pagnier, Igal Goldshtein +3
Power system operators routinely perform N-1 contingency analysis, yet conventional tools provide limited guidance on which lines or transformers deserve heightened attention durin…
Real-Time Stochastic Assessment of Dynamic N-1 Grid Contingencies
Ayrton Almada, Laurent Pagnier, Igal Goldshtein +3
Power system operators need tools for rapid, real-time counterfactual assessments of grid security under fast-changing conditions. Traditional N-1 contingency analysis lacks dynami…
Lagrangian Attention Tensor Networks for Velocity Gradient Statistical Modeling
Criston Hyett, Yifeng Tian, Michael Woodward +4
Direct numerical simulation of turbulence at realistic Reynolds numbers is still beyond current computational capability, necessitating models that reduce the number of resolved sp…
Physics-Guided Actor-Critic Reinforcement Learning for Swimming in Turbulence
Christopher Koh, Laurent Pagnier, Michael Chertkov
Turbulent diffusion causes particles placed in proximity to separate. We investigate the required swimming efforts to maintain an active particle close to its passively advected co…
System-Wide Emergency Policy for Transitioning from Main to Secondary Fuel
Laurent Pagnier, Criston Hyett, Robert Ferrando +4
Faced with the complexities of managing natural gas-dependent power system amid the surge of renewable integration and load unpredictability, this study explores strategies for nav…
Differentiable Simulator For Dynamic & Stochastic Optimal Gas & Power Flows
Criston Hyett, Laurent Pagnier, Jean Alisse +4
In many power systems, particularly those isolated from larger intercontinental grids, operational dependence on natural gas becomes pivotal, especially during fluctuations or unav…
