CURENT Power and Energy Seminar

Presenter: Dr. Sid Suryanarayanan, Colorado State University

Title: ToU, or not ToU, that is the question - Maximizing Wind Energy Usage in Regions with Electric Vehicle Fleets

Abstract: Worldwide, there is significant growth in the installed capacity of wind energy based power plants. While they provide a reprieve from greenhouse gas emissions, the inherent stochasticity in the availability of wind introduces problems of deviations from forecasts. Sans efficient and inexpensive solutions for grid-level energy storage, wind power plants have to rely on economically unviable operational methods such as curtailment. The growing presence of plug-in electric vehicle (PEV) fleets in electricity distribution systems may provide an avenue for avoiding curtailments by scheduling their charging during over-supply of wind energy. 

In this talk, we will explore a data-driven methodology for studying existing pricing mechanisms in a North American metropolis, located in a wind energy-rich grid with an increased adoption rate of PEVs. Our study shows that the existing pricing methods for encouraging PEV charging to consume excess wind are sub-optimal. We will justify a need for an alternative dynamic pricing mechanism - Time of Use (ToU) - dedicated to PEVs for maximizing the usage of available energy from wind. Such a dedicated ToU can help avoid high costs for the supplier and deliver benefits to the responsive consumers. 

Using real data and a machine learning methodology for data decomposition, we have designed a ToU dedicated for PEVs in the city under consideration. We will conclude this talk with some thoughts on the future directions of this research.

About the CURENT Power & Energy Seminar Series: CURENT invites students, industry leaders and academic experts to participate in our seminars at the center's lead institute, the University of Tennessee, every Friday during the semester. Industry seminars are typically on the last Friday of each month (Note: seminars may be scheduled on other days based on speaker availability). Seminars cover a variety of topics related to the ongoing research and technical development of the nation's power grid. The seminar also fulfills the class requirements for ECE 496 and ECE 691.

CURENT is a National Science Foundation and Department of Energy Engineering Research Center headquartered at UT. Partner institutions are Northeastern University, Rensselaer Polytechnic Institute, and Tuskegee University.
