Abstract
The resiliency of the electric power grid to extreme events is a fundamental motivation for modernizing the aging and vulnerable critical infrastructure.
The alarming rise in the number of incidences of cyber-attacks and severe storms over the last few years have caused prolonged power outages for millions of customers.
The financial impact of these events upon the utilities has been several hundred billions of dollars.
The objective of this dissertation is to develop a comprehensive framework and algorithms for enabling resiliency of power distribution systems - encompassing time-span from planning to post-event restoration and recovery that would minimize the power outages resulting in less economic losses and public inconveniences.
Some of the main challenges of the industry in planning - are the broad range of interpretations of power distribution system resiliency, based on the time available for preparing before an event happens and recovering afterward, and lack of detailed, region-specific distribution models.
This dissertation addresses these problems extensively.
A mathematical model for studying the propagation of extreme events in the cyber-physical power grid has also been discussed.
Enabling resiliency in near-term or during the contingency requires the ability to perform power flow and restoration calculations for the impending or ongoing threat.
Thus, an event-driven proactive network reconfiguration strategy has been proposed, to study how the path of propagation can impact the operation and restoration of the power distribution system.
In the aftermath of an event, the distribution system infrastructure is characterized by uncertain topology, load demand, power resources, and time until power can be completely restored to all customers.
In this work, the resiliency of the electric grid has been studied as a robust optimization problem for the effective allocation of scant resources to meet the demands of critical customers during prolonged periods of power outage.
The proposed theory and algorithms in this dissertation have been tested on IEEE test systems as well as validated against actual data available from industry partners.
