Webinar on 2/24/2021: Assessment of an AC Interconnection of the North American Eastern and Western Electric Grids

This webinar was presented by Dr. Thomas Overbye, Texas A&M University.

Abstract: Except for a brief time around 1970, the North American Eastern and Western grids have operated asynchronously from each other, with power transfers only possible through a few back-to-back HVDC ties. However a recent study has shown that an AC interconnection may be possible. This talk will present the dynamic and steady-state issues that need to be considered in contemplating synchronous operation of such a large-scale grid. The talk will also present new techniques for visualizing the results of the large-scale, long duration dynamic simulations needed for doing this assessment. Finally results will be presented demonstrating the methodology using an 80,000 bus synthetic electric grid and a 110,000 bus actual electric grid model.

Webinar was held at 3 P.M. CST on February 24, 2021.
