Modelling, Dynamics and Control of Aggregate Load Models
Dr. Hiskens is the Vennema Professor in the Department of Electrical Engineering and Computer Science at the University of Michigan at Ann Arbor. Dr. Hiskens' research interests lie at the intersection of power system analysis and systems theory, in particular modelling, optimization, dynamics and control of large-scale, networked, nonlinear systems. Professor Hiskens is a Fellow of the IEEE, a Fellow of Engineers Australia, and a Chartered Professional Engineer in Australia.
Aggregate models underpin the analysis, simulation and control of large populations (ensembles) of small loads. Of particular interest are loads that operate according to hysteresis controls, for example thermostatically controlled loads (TCLs) such as residential air-conditioners. So-called bin models form the basis for such load aggregation. The presentation will consider the accuracy and fidelity of bin models. Focusing on residential air-conditioners, it will explore bin model extensions that cater for temperature delay and multi-zone interactions. Various load ensemble control strategies are prone to undesirable, highly nonlinear forms of behaviour including synchronization, sustained oscillations and bifurcations. The nature of such dynamic behaviour will be explored and the implications for controller design will be considered.

Prof Ian Hiskens
Modelling, Dynamics and Control of Aggregate Load Models
Biography:
Ian A Hiskens received the BEng (Elec) and BAppSc (Math) degrees from the Capricornia Institute of Advanced Education, Rockhampton, Australia in 1980 and 1983 respectively. He received the PhD degree in Electrical Engineering from the University of Newcastle, Australia in 1991. Dr. Hiskens is the Vennema Professor of Engineering in the Department of Electrical Engineering and Computer Science at the University of Michigan at Ann Arbor. From 1980 to 1992, he was with the Queensland Electricity Supply Industry, where he held the positions of EMS Security Applications Engineer and Planning Engineer Transmission Systems. From 1992 to 1999, he was a Senior Lecturer at the University of Newcastle, Australia, from 1999 to 2002 a Visiting Professor in the Department of Electrical and Computer Engineering at the University of Illinois at Urbana-Champaign, and from 2002 to 2008 a Professor in the Department of Electrical and Computer Engineering at the University of Wisconsin-Madison. Dr. Hiskens' research interests lie at the intersection of power system analysis and systems theory, in particular modelling, optimization, dynamics and control of large-scale, networked, nonlinear systems. His recent activity has focused largely on integration of renewable generation and controllable loads. Professor Hiskens is a Fellow of the IEEE, a Fellow of Engineers Australia, and a Chartered Professional Engineer in Australia.
