The FIND Seminar is a bi-weekly seminar series that hosts cutting-edge research talks on topics related to the broad themes of Foundations of Information, Networks and Decision Systems. Talks are about 50 minutes long with time for questions and discussion.
Location: Rhodes Hall 310 and Zoom
Time: 4:15PM ET, bi-weekly on (alternating) Thursdays
Delivery format: All talks will have a live audience in Rhodes Hall 310. Until circumstances allow otherwise, external speakers will give the talk remotely via Zoom (broadcasted in RH310). Remote audience is also welcome, but in-person participation is encouraged.
Mailing list: To subscribe to the FIND seminar mailing list, email find-seminar-l-request@cornell.edu, with “join” in the subject line and a blank email body. All talks info and reminders will be sent via the mailing list.
Upcoming Talk (Note that this upcoming talk will be given at Bloomberg 201)
Title: Geometry of Distance Protection
Speaker: Josh Taylor
Date and Time: 12/04/2025, 4:15PM ET
Location: Bloomberg 201 and Zoom

Abstract:
Distance relays detect faults on transmission lines. They face uncertainty from the fault’s location and resistance, as well as the current from the line’s remote terminal. In this paper, we aggregate this uncertainty with the Minkowski sum. This allows us to explicitly model the power grid surrounding the relay’s line, and in turn accommodate any mix of synchronous machines and inverter-based resources. To make the relay’s task easier, inverters can inject perturbations, or auxiliary signals, such as negative-sequence current. We use Farkas’ lemma to construct an optimization for designing inverter auxiliary signals.
