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…
A K-Nearest Neighbor Heuristic for Real-Time DC Optimal Transmission Switching
Emma S. Johnson, Shabbir Ahmed, Santanu S. Dey +1
While transmission switching is known to reduce power generation costs, the difficulty of solving even DC optimal transmission switching (DCOTS) has prevented optimal transmission…
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…
