Techno-Economic Analyses of Large-Scale Electric Vehicle Systems

This project has developed computer models to evaluate the techno economic implications of a large-scale electrified transportation sector. The model factors include developing a network of EVs and the electric grid, developing the infrastructure for EV charging, integrating the transportation and power systems into the urban setting, studying the impact of distributed energy storage and determining the economic impact of increased renewable energy and EVs on the electricity grid. The current research focuses upon several innovative aspects of vehicle-to-grid (V2G) charging and grid feedback. Results are presented in four papers. Results show that energy storage and reactive power supplied by EVs through V2G operation can be coordinated to provide voltage support, thus reducing the need of grid reinforcement and active power curtailment and in turn improving EV charging capacity of the overall system. An optimization and control framework is needed to manage energy storage while using the remaining capacity of V2G to generate reactive power and cooperatively perform voltage control. The resilience analyses of power grid with a high level of renewable and EV penetration has been investigated. To present this result, a resiliency index was used that will capture the total loads which cannot be supplied under line removal due to extreme weather conditions. Using this index, a control strategy based on line switching is proposed to minimize the total load shedding and to guarantee the power delivery to critical loads due to line outages. This project and its V2G results have a very broad scope and implications.
