1st Interdisciplinary Workshop on Smart Grid Design & Implementation

Technical limits of penetration of asynchronous wind and PV generation in an AC interconnection
Janusz Bialek
Professor Janusz Bialek received his MEng and PhD degrees in Electrical Engineering from Warsaw University of Technology in 1977 and 1981, respectively. From 1981 to 1989 he was a lecturer at Warsaw University of Technology. In 1989 he moved to Durham University. From 2003 to 2009 he held Bert Whittington Chair of Electrical Engineering at the University of Edinburgh. He returned to Durham University in September 2009 to take up the Chair of Electrical Power and Control. He is also Research Director of School of Engineering and Computing Sciences. He will be seconded to Department of Energy and Climate Change (DECC) from June to December 2012 as DECC/EPSRC Science Policy Fellow.
Janusz is Fellow of Institute of Electrical and Electronics Engineers (IEEE). He is a former member of Advisory Board of Electricity Policy Research Group, Cambridge University, member of the Dispute Resolution Panel for the Single Electricity Market Operator, Ireland, and Honorary Professor of Heriot-Watt University, UK. He has sat on Technical Committees of major power engineering conferences including Power System Computation Conference and IEEE PowerTech and IEEE Innovative Smart Grid Technologies Europe. He was a Visiting Professor at Swiss Federal Institute of Technology (EPFL) in 2000, and at Hong Kong University in 2008.
Wind and PV generation is usually connected to the grid using an asynchronous interface: induction generator in the case of wind and DC/AC converter  in the case of PV. As the operation of the power system is based around synchronous operation of synchronous generators used in traditional coal/gas/nuclear/hydro power stations , there is a technical limit of how much asynchronous generation can be connected to an AC interconnection. Recent studies in Ireland indicate that the limit is about 50-75% of the total generation operating at any time. The talk will discuss the physical reasons for the limit and possible means of overcoming it.
