Forced oscillation source localization from generator measurements
Melvyn Tyloo, Marc Vuffray, Andrey Y. Lokhov
Malfunctioning equipment, erroneous operating conditions or periodic load variations can cause periodic disturbances that would persist over time, creating an undesirable transfer…
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…
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…
Graphical Models for Optimal Power Flow
Krishnamurthy Dvijotham, Pascal Van Hentenryck, Michael Chertkov +2
Optimal power flow (OPF) is the central optimization problem in electric power grids. Although solved routinely in the course of power grid operations, it is known to be strongly N…
Natural Gas Flow Solutions with Guarantees: A Monotone Operator Theory Approach
Krishnamurthy Dvijotham, Marc Vuffray, Sidhant Misra +1
We consider balanced flows in a natural gas transmission network and discuss computationally hard problems such as establishing if solution of the underlying nonlinear gas flow equ…
