Title:

Data-Driven and Hurricane-Focused Metrics for Combined Transportation and Power Networks Resilience

Abstract:

Hurricane Hermine was the first hurricane to make landfall in Florida since Hurricane Wilma in 2005, and was the first hurricane to directly hit Apalachee Bay since Hurricane Alma in 1966. As a result, Hermine left 100,000 residents without power in the City of Tallahassee, the capital of Florida, knocking out trees, power lines and shutting down stores and businesses for days. As such, this paper provides a resilience analysis of Hermine’s impact in Tallahassee based on real-life data on roadway closures due to fallen trees and power outages. This type of analysis can provide critical understanding and insight on where and why the power and transportation infrastructure shall increase both flexibility and adaptability to cope with such unexpected and severe disruptions. New metrics are developed in the context of resilience, priority and vulnerability of electric grid and roadway networks in order to assess the hurricane impact in the city. Findings show that the City of Tallahassee power utility followed an effective remedial action scheme to cope with the unexpected disruptions caused by Hermine. The conducted restoration approach allowed the City of Tallahassee to control outage duration in time, prioritizing the restoration of power systems devices hierarchically upstream the system, and providing the power reconnection to the largest customer groups first. Using the proposed metrics, it was also possible to identify the most disrupted feeders with respect to prioritized customers and outage duration so that the city can pinpoint those locations, which can be considered for future resilience-oriented investments.
