Online Learning of Power Transmission Dynamics
Andrey Y. Lokhov, Marc Vuffray, Dmitry Shemetov +2
We consider the problem of reconstructing the dynamic state matrix of transmission power grids from time-stamped PMU measurements in the regime of ambient fluctuations. Using a max…
Fast and Robust Determination of Power System Emergency Control Actions
Sidhant Misra, Line Roald, Marc Vuffray +1
This paper outlines an optimization framework for choosing fast and reliable control actions in a transmission grid emergency situation. We consider contractual load shedding and g…
Information Theoretic Optimal Learning of Gaussian Graphical Models
Sidhant Misra, Marc Vuffray, Andrey Y. Lokhov
What is the optimal number of independent observations from which a sparse Gaussian Graphical Model can be correctly recovered? Information-theoretic arguments provide a lower boun…
Graphical Models and Belief Propagation-hierarchy for Optimal Physics-Constrained Network Flows
Michael Chertkov, Sidhant Misra, Marc Vuffray +2
In this manuscript we review new ideas and first results on application of the Graphical Models approach, originated from Statistical Physics, Information Theory, Computer Science…
