A Trilevel Model for Segmentation of the Power Transmission Grid Cyber Network
Bryan Arguello, Emma S. Johnson, Jared L. Gearhart
Network segmentation of a power grid's communication system is one way to make the grid more resilient to cyber attacks. We develop a novel trilevel programming model to optimally…
A Scalable Lower Bound for the Worst-Case Relay Attack Problem on the Transmission Grid
Emma S. Johnson, Santanu S. Dey
We consider a bilevel attacker-defender problem to find the worst-case attack on the relays that control the transmission grid. The attacker maximizes load shed by infiltrating a n…
An Exact and Scalable Problem Decomposition for Security-Constrained Optimal Power Flow
Alexandre Velloso, Pascal Van Hentenryck, Emma S. Johnson
In this paper, we present decomposition techniques for solving large-scale instances of the security-constrained optimal power flow (SCOPF) problem with primary response. Specifica…
