Impact Analysis of EV load on Low-Voltage Distribution Systems": GBS POWER AND ENERGY WEEK PRESENTATION
This is the third and final presentation of GBS POWER AND ENERGY WEEK.
Achieving net-zero emissions is a global challenge, requiring technical innovations, policy making, investment, and cultural change. A major aspect of this challenge is the electrification of aerial, marine, and ground transportation. The past decade has witnessed the exponential growth of electric vehicles (EVs), aided by improved design, cost reduction, tax credits, and environmental awareness. To meet this growth rate, charging infrastructure must be developed, modernized, and improved as per the charging demand. However, the impact of adding EVs as charging loads to the utility grid makes this infrastructure update more complex, especially in low-voltage distribution systems. Thus, to address this complex process, a thorough understanding of the underlying charging speeds, existing load demand, and voltage profile/power quality of the utility grid is necessary.
This talk focuses on exploring the key players of EV impact on utility grids. Different charging strategies to demonstrate the power variance as a function of charging speed will be discussed, followed by design requirements of onboard vs offboard chargers. Datasheets of a few commercial chargers will be examined. The impact of adding EVs on the grid vitals like voltage profile, peak load, average demand, and unit pricing will be analyzed. Finally, case studies of a 33-bus IEEE system, with an estimation of EV penetration capability, and potential solutions to maximize the penetration will be

Biography:
Syed Rahman (S’21) received B.E (Electrical and Electronics Engineering-Gold Medal) from Osmania University, India in 2012. He completed his M. Tech (Specialization: Machine Drives and Power Electronics) from IIT Kharagpur, India in 2014. He is currently pursuing a Ph.D. degree in electrical engineering from Texas A&M University, USA. He worked as an R&D “Design Engineer” at GE Healthcare, India from Oct 2014 to Jan 2016. From Feb 2016 to Dec 2019, he worked as a “Research Associate” at Qatar University, on a research project funded by Qatar Foundation. His areas of interest include renewable energy integration, multilevel inverters, cold-ironing in marine vessels, and impact analysis of slow/fast charging solutions on the utility grid. He has published more than 25 refereed journal articles, 25 conference papers, and 1 US patent in the field of power electronics and renewable energy integration. He was also a recipient of the Thomas W. Powell '62 and Powell Industries Inc. Fellowship in 2021 and is an Energy institute Fellow of Texas A&M Energy Institute for the year 2022-2023.
