Benefits and Challenges of Power Electronics Enabled Flexibility of Power Systems

The future power/energy  systems will be characterised by blurred boundaries between transmission and distribution system, by mix of wide range of electricity generating technologies (conventional hydro, thermal, nuclear and power electronic interfaced stochastic and intermittent renewable generation), responsive and highly flexible, typically power electronics interfaced, demand and storage with significant temporal and spatial uncertainty, proliferation of power electronics (HVDC, FACTS devices and new types of load devices) and significantly higher reliance on the use of measurement data including global (Wide Area Monitoring) signals for system identification, characterization and control and Information and Communication Technology embedded within the power system network and its components.

The key characteristic of such a complex system, if it is only one to be picked, would certainly be prolifereation of power electronic devices in  different shapes and forms and for different purposes. This will increase controllability and observability of the system but may as a trade off  result in different/unexpected dynamic behaviour of the system and possibly, under some circumstances,  deterioration of some  aspects of its performance. This presentation identifies some of the challenges associated with operation and control of power systems with significant pentetration of power electronics interfaced generation and loads and approaches to identify, model and overcome them.


Jovica V MilanovicJovica V Milanovic received Dipl.Ing. and M.Sc. degrees from the University of Belgrade, Yugoslavia, Ph.D. degree from the University of Newcastle, Australia, and D.Sc. degree from The University of Manchester, UK. Prior to joining The University of Manchester, UK, in 1998, he worked with “Energoproject”, Engineering and Consulting Co. and the University of Belgrade in Yugoslavia, and the Universities of Newcastle and Tasmania in Australia.

Currently, he is a Professor of Electrical Power Engineering, Deputy Head of  School  and Director of External Affairs   in the School of Electrical and Electronic Engineering  at The University of Manchester, UK , Visiting Professor at the University of Novi Sad and the University of Belgrade, Serbia and Conjoint Professor at the University of Newcastle, Australia. He was chairman of 4 international conferences, editor or member of editorial/technical boards of 70+ international journals and conferences, research project assessor for numerous international government research funding councils, member of 9 (convenor of 3) past or current IEEE/CIGRE/CIRED WG and consultant or member of advisory boards for several international companies. Professor Milanovic  published  close to 500 research papers and reports, gave 20+ key-note speeches at international conferences and presented over 140 courses/tutorials and lectures to industry and academia around the world.

Professor Milanovic  is a Chartered Engineer in the UK, Foreign member of the Serbian Academy of Engineering Sciences, Fellow of the IET, Fellow of the IEEE, Distinguished IEEE PES Lecturer and  currently serves on  IEEE PES Governing Board as  Regional Representative for Europe, Middle east and Africa and as a vice-chair of the IEEE PES Fellows Committee.
