Friday SLC Seminar Series

The SLC Seminar happens every Friday from 12:20 pm to 1:10 pm unless otherwise noted.  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 although 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.There is pizza at the Friday seminars.

Presenters: Dr. Chien-fei Chen and Wenyun Ju

Time: Friday, January 12th, 12:20 PM - 1:10 PM EST

Location: Min H. Kao Building, Room 622

This meeting will be available through ZOOM for faculty, partner school students and industry. ZOOM info follows the speaker info.

Presenter: Dr. Chien-fei Chen, Director of Education and Diversity Programs and Research Professor, CURENT

Title: Overview of CURENT education and diversity program and new requirement of IMPACT program.

Bio: Dr. Chien-fei Chen is a research professor and director of education and diversity program at NSF-DOE funded engineering research center, Center for Ultra-wide-area Resilient Electric Energy Transmission Networks (CURENT), Department of Electrical Engineering and Computer Science at the University of Tennessee, Knoxville. She is also an adjunct faculty in the department of sociology. Her research interests include interdisciplinary research of power systems, renewable energy, energy conservation behaviors and environmental sociology. Her recent publications appear in the IEEE, Building and Environment, Energy, Energy Research and Social Science, Journal of Environmental Psychology, ASHRAE, American Sociological Association, Behavior, Energy and Climate Change Conference, and so on. Currently, she leads the projects of public acceptance of power grid technologies and demand response at CURNET. Since 2014, she has involved with the investigation of social psychological factors affecting building occupant behaviors for the International Energy Agency (IEA), Energy in Buildings and Communities (EBC) Annex 66. Additionally, she leads sustainability education program and social psychological analysis of energy behaviors for the NSF-REC-SEES Network: Predictive Modeling Network for Sustainable Human-Building Ecosystems (SHBE). She has received several grant awards from National Science Foundation to conduct interdisciplinary studies regarding public acceptance of communication technology and social-psychological factors and micro-grid resilience and acceptance of grid technologies.

Title: Simulation of Cascading Outages Considering Frequency Using a Dynamic Power Flow Model

Abstract: Frequency is an important indicator of the real-time imbalance between active power generation and load, which, however, is not considered by traditional steady-state models for cascading outage simulation. This talk proposes a novel dynamic power flow (DPF) model for cascading outage simulation considering static power-frequency characteristics (SPFCs) of generators and loads such that system frequency deviations due to active power imbalance can be calculated during cascading outages. Further, a new AC optimal power flow model considering frequency deviation (AC-OPFF) is proposed to represent remedial control actions when system collapse happens as indicated by power flows divergence. Case studies demonstrate the proposed approach for the simulation of cascading outages.

Bio: Wenyun Ju was born in Wuhu, Anhui Province in China and recieved his B.S. degree and M.S. degree in Electrical Engineering from Sichuan University, Chengdu, China in 2010 and Huazhong University of Science and Technology, Wuhan, China in 2013, respectively. He is currently working toward his Ph.D. in the Department of EECS at the University of Tennessee, Knoxville. His research interest is modeling and simulation of cascading outages in power systems.
