Dr. Tony Kerzmann’s higher education background began with a Bachelor of Arts in Physics from Duquesne University, as well as a Bachelor’s, Master’s, and PhD in Mechanical Engineering from the University of Pittsburgh. After graduation, Dr. Kerzmann began his career as an assistant professor of Mechanical Engineering at Robert Morris University which afforded him the opportunity to research, teach, and advise in numerous engineering roles. He served as the mechanical coordinator for the RMU Engineering Department for six years, and was the Director of Outreach for the Research and Outreach Center in the School of Engineering, Mathematics and Science. In 2019, Dr. Kerzmann joined the Mechanical Engineering and Material Science (MEMS) department at the University of Pittsburgh. He is the advising coordinator and associate professor in the MEMS department, where he positively engages with numerous mechanical engineering advisees, teaches courses in mechanical engineering and sustainability, and conducts research in energy systems.
Throughout his career, Dr. Kerzmann has advised over eighty student projects, some of which have won regional and international awards. A recent project team won the Utility of Tomorrow competition, outperforming fifty-five international teams to bring home one of only five prizes. Additionally, he has developed and taught fourteen different courses, many of which were in the areas of energy, sustainability, thermodynamics, dynamics and heat transfer. He has always made an effort to incorporate experiential learning into the classroom through the use of demonstrations, guest speakers, student projects and site visits. Dr. Kerzmann is a firm believer that all students learn in their own unique way. In an effort to reach all students, he has consistently deployed a host of teaching strategies into his classes, including videos, example problems, quizzes, hands-on laboratories, demonstrations, and group work. Dr. Kerzmann is enthusiastic in the continued pursuit of his educational goals, research endeavors, and engagement of mechanical engineering students.
Robert J Kerestes University of Pittsburgh
Robert Kerestes, PhD, is an assistant professor of electrical and computer engineering at the University of Pittsburgh's Swanson School of Engineering. Robert was born in Pittsburgh, Pennsylvania. He got his B.S. (2010), his M.S (2012). and his PhD (2014) from the University of Pittsburgh, all with a concentration in electric power systems. Robert’s academic focus is in education as it applies to engineering at the collegiate level. His areas of interest are in electric power systems, in particular, electric machinery and electromagnetics. Robert has worked as a mathematical modeler for Emerson Process Management, working on electric power applications for Emerson’s Ovation Embedded Simulator. Robert also served in the United States Navy as an interior communications electrician from 1998-2002 on active duty and from 2002-2006 in the US Naval Reserves.

Abstract
The U.S. is rapidly electrifying its vehicle fleet. The electric vehicle (EV) market in the United States has grown from just over ten thousand vehicles in 2011 to more than 215,000 vehicles sold in 2020. In 2020, the EV share of new vehicle sales was approximately 1.7%, an increase from about 1.4% in 2019. With a national goal of EV sales accounting for half of all new car sales by 2030, the grid is going to see some significant changes to its power consumption. The forecasted surge in the number of EVs elucidates the issue of rapidly increasing power loads from EV charging in residential and workplace applications. This rapid power variation on the existing grid infrastructure can have some important effects on the grid system and should be better understood. Many parts of the current electric grid date back more than 50 years and rapid changes to the power consumption curve can have negative effects on grid reliability.
This project focuses on the modeling of the effects of EV charging stations on the existing grid infrastructure. The modeling incorporates time-series and stochastic modeling approaches to identify key locations where the risk of failure may occur. A series of EV charging scenarios are modeled to evaluate the changes in grid voltage based on the localized grid power consumption. The nodal grid array that is simulated is modeled after data provided from Duquesne Light Company (DLC), a City of Pittsburgh electricity utility provider. The charging scenarios are modeled in the open-source OpenDSS software developed by the Electric Power Research Institute (EPRI) and utilize EV scenario data from the Department of Energy’s Electric Vehicle Infrastructure Projection Tool (EVI-Pro) Lite. This research provides a successful example of an industry-academia collaboration of an engineering student research project. The findings from grid modeling will be presented along with the student educational components that were involved throughout the research and collaboration process.
