A Methodology of Utilizing Electric Vehicles to Improve the Reliability and Resiliency of the Power System in Extreme Weather
Abstract
In the thesis, a new methodology is presented to investigate the impact of electric vehicles on the power system. The goal is to assess the benefits of using electric vehicles as a power source to enhance the grid’s reliability and resilience during extreme weather conditions. The proposed methodology involves modeling electric vehicle charging load and discharging capacity in time series data obtained from the travel demand model in Texas A&M Transportation Institute, map-ping electric vehicle charging load and discharging capacity to the power system, and simulating and solving the optimal power flow in Powerworld with extreme weather situations. The research focuses on the case study of the winter storm Uri, which occurred in February 2021 in Texas, affecting a significant part of the United States. The studied grid is a synthetic 7000-bus electric grid on the Texas footprint to mimic the Electric Reliability Council of Texas system without revealing any confidential data. The result demonstrates that utilizing electric vehicles as a power source can help avoid power outages as well as the necessity of load shedding in extreme weather cases.
