Impact Analysis of EV load on Low-Voltage Distribution Systems”: GBS POWER AND ENERGY WEEK PRESENTATION

Virtual: https://events.vtools.ieee.org/m/318561

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 Speaker(s): SYED, Virtual: https://events.vtools.ieee.org/m/318561
