Special Seminar: Concept and Applications of Critical Load Level in Locational Marginal Pricing Based Economic Studies

Fangxing (Fran) Li, Associate Professor, Department of Electrical Engineering and Computer Science at The University of Tennessee at Knoxville & Campus Director of CURENT (NSF Engineering Research Center)

Monday, April 13, 2015, 4:00–5:00pm

Room 200, Cummings Hall

In this seminar, a brief overview of electric power market operation will be discussed and the locational marginal pricing (LMP) method will be presented. Then, the concept of critical load level (CLL) will be proposed to illustrate the step changes of the LMPs when the system load varies. Next, a linearized optimal power flow model is employed to illustrate the CLL concept with a comparison with non-linear full AC power flow model. CLL is an indication of a binding constraint due to different sensitivity of marginal generation to system load variation, which provides useful information for LMP-based market studies. Finally, several applications based on CLL, such as probabilistic LMP and impact from wind energy as well as demand response, will be discussed.

About the Speaker

Fangxing Li also know as Fran Li, is presently an associate professor in the Department of Electrical Engineering and Computer Science at The University of Tennessee at Knoxville (UTK). He also serves as the Campus Director of CURENT, a NSF Engineering Research Center and one of the largest research centers in electric power engineering in the U.S. Professor Li received his BSEE and MSEE degrees both from Southeast University (China) in 1994 and 1997, respectively, and then his Ph.D. degree from Virginia Tech in 2001. Prior to joining UTK in 2005, he had worked at ABB Electrical System Consulting (ESC) in Raleigh, NC, from 2001 to 2005, as a senior engineer and then a principal engineer. During his employment at ABB, he was the lead developer of GridView Releases 1.0 and 2.0. Presently, GridView is a major power-market simulator with a number of users at power utilities and Independent System Operators (ISOs), as well as being an internal consulting tool for ABB consultants. His current research interests include power markets, renewable energy integration, smart grid, and distributed energy resources. He has published more than 70 journal papers and 100 conference papers and holds a US patent and an international patent. Professor Li is a registered Professional Engineer (P.E.) in the state of North Carolina, an Editor of IEEE Transactions on Sustainable Energy, the Vice Chair of IEEE PES Power System Planning and Implementation (PSPI) committee, and IEEE PES General Meeting TCPC member, the President of North America Chinese Power Professional Association (NACPPA) and a Fellow of IET.
