Dissertation Title: A Wide-area Analysis of Shifts in Electric Power System Generation Profiles and High-impact Event Scenarios
Mentor: Dr. Yilu Liu
Dissertation Description: Often cited as the largest machine in the world, the electric power grid is a complex system, integral to modern life. Continuous technology advancements over the past hundred years have delivered improvements to both the system itself, e.g., wide-area management systems (WAMS), as well as modeling capabilities in order to better understand how that system functions. Phenomena that could once be simulated only in small, localized settings can now be studied from a wide-area perspective.
There are two topics that wide-area modeling must address: the effect of generation portfolio changes on dynamic system response and the assessment and hardening of the grid against high-impact, interconnection-wide events.
The first topic is investigated through an examination of the dynamic response repercussions of the recent shift from coal-fired generation plants to natural gas turbines and the increase in low-inertia renewable sources.
The second topic is discusses using modeling and analysis of wide-area events include geomagnetically induced current (GIC) effects and high-altitude electromagnetic pulse (HEMP) components and impacts. Guided by the 2015 Fixing America’s Surface Transportation (FAST) Act, the scope of this analysis is extended to present a methodology to find the most critical elements for any given system and determine the minimum required spare large power transformer (LPT) reserve that should be available.
