Seminar Topic: Profit-Maximizing Planning and Control of Battery Energy Storage Systems for Primary Frequency Control

Speaker: Angela Yingjun Zhang
Time: Dec. 29, 10:15 a.m. - 11:15 a.m.
Venue:  Room 1A-200, SIST Building

We consider a two-level profit-maximizing strategy, including planning and control, for battery energy storage system (BESS) owners that participate in the primary frequency control (PFC) market. Specifically, the optimal BESS control minimizes the operating cost by keeping the state of charge (SoC) in an optimal range. Through rigorous analysis, we prove that the optimal BESS control is a ``state-invariant" strategy in the sense that the optimal SoC range does not vary with the state of the system. As such, the optimal control strategy can be computed offline once and for all with very low complexity. Regarding the BESS planning, we prove that the the minimum operating cost is a decreasing convex function of the BESS energy capacity. This leads to the optimal BESS sizing that strikes a balance between the capital investment and operating cost. Our work here provides a useful theoretical framework for understanding the planning and control strategies that maximize the economic benefits of BESSs in ancillary service markets.

Angela Yingjun Zhang received her PhD degree in Electrical and Electronic Engineering from the Hong Kong University of Science and Technology, Hong Kong in 2004. Since 2005, she has been with Department of Information Engineering, The Chinese University of Hong Kong, where she is currently an Associate Professor. Her research interests include mainly wireless communications systems and smart power systems, in particular optimization techniques for such systems. 
She is an Executive Editor of the IEEE Transactions on Wireless Communications. She is also an Associate Editor of the IEEE Transactions on Communications. Previously, she served many years as an Associate Editor of the IEEE Transactions on Wireless Communications, Security and Communications Networks (Wiley), and a Feature Topic in the IEEE Communications Magazine. She has served as a Workshop Chair of IEEE ICCC 2014 and 2013, TPC Vice Chair of Wireless Networks and Security Track of IEEE VTC 2014, TPC Vice-Chair of Wireless Communications Track of IEEE CCNC 2013, TPC Co-Chair of Wireless Communications Symposium of the IEEE GLOBECOM 2012, Publication Chair of the IEEE TTM 2011, TPC Co-Chair of Communication Theory Symposium of the IEEE ICC 2009, Track Chair of ICCCN 2007, and Publicity Chair of the IEEE MASS 2007. She was a Co-Chair of the IEEE ComSoc Multimedia Communications Technical Committee and the IEEE Communication Society GOLD Coordinator. 
She was the co-recipient of the 2014 IEEE ComSoc APB Outstanding Paper Award, the 2013 IEEE SmartgridComm Best Paper Award, and the 2011 IEEE Marconi Prize Paper Award on Wireless Communications. She was the recipient of the Young Researcher Award from the Chinese University of Hong Kong in 2011. As the only winner from engineering science, she has won the Hong Kong Young Scientist Award 2006, conferred by the Hong Kong Institution of Science. Dr. Zhang is a Fellow of IET.
