I spent six months working full time in the company commissioning the program. 3. UNIVERSITY EDUCATION Feb 1997 - Sept 1997 Open University Part-time course entitled “Renewable Energy”. 1989-1991 Department of Engineering, University of Cambridge Ph.D. Awarded in 1991: Improved Calculation Methods for Particular Aspects of Induction Motor Performance, 1985-1989 Department of Electrical & Electronic Engineering, Imperial College of Science, Technology & Medicine, London B.Sc.(Eng) 2.1 Honours, awarded in 1988, 1st year PhD in 1989. 4. RESEARCH IMPACT & ACHIEVEMENTS NGenTec Ltd: I am technical advisor to the company and was a non-executive board member. In 2009 I spun out NGenTec Ltd from the University of Edinburgh, which was established to commercialise a novel permanent magnet generator technology for direct drive wind applications. In December 2010 the company signed a £2m investment deal with 2 VCs, and an industrial partnership with David Brown Gear Systems Ltd. worth just under £1m. DECC awarded the company a grant of £800k. The investment will be used to scale up the technology to multi-MW wind turbines. A total of 15 jobs have so far been created including a senior management team with 100 years of combined experience in the machines and renewable energy industry. Electrical Machines and Power Electronics Research Group: Prior to my appointment in January 2004 there had been no machines research. I have attracted £4m of funding up to 2014 equating to £400k per annum of income, and 78% of the total is as Principal Investigator. For the last 2-3 years I have sustained a membership of 15 PhDs and RAs, and the group is continuing to expand. Publications: Since 2004 I have published 23 journal papers (5 were invited), 43 conference papers (full paper refereed) and 3 patents have been filed. In 2006 I was awarded the Donald Julius Groen Prize by the IMechE and in 2010 was awarded Best Paper at the International Conference on Electrical Machines. I have been invited to give a key note presentation at the 1st IET Renewable Power Generation Conference in Sept 2011. UK Energy Research Centre (UKERC): In 2007 I co-authored the first technology roadmap for marine renewable energy as part of my involvement in UKERC, attracting national and international interest. The Carbon Trust, the Energy Technologies Institute, US Dept. of Energy, and Natural Resources Canada have all used it to develop their own marine renewable R&D programmes. It has been adopted as an Annexe within the IEA Ocean Energy Group. Knowledge Exchange: Since March 2008 I have been running a renewable energy knowledge transfer network, RENEW-NET, funded by the Scottish Government. The KE activity is focused on providing SMEs in the renewable energy sector with technical support in electrical power engineering. In April 2011, I was awarded £904k by the Scottish Funding Council and European Regional Development Funds to continue until 2014 and expand the network from the original partners, Edinburgh, Glasgow and Strathclyde, to include Aberdeen and Heriot Watt Universities. Since its establishment RENEW-NET has increased R&D investment within SMEs by £5m and created or secured 25-30 positions. GE Energy & Power Conversion (formerly Converteam) Advanced Technology Group: In 2010, Converteam (bought by GE in Sept 2011) established its first UK Advanced Technology Group (ATG) at the University of Edinburgh to work with the Electrical Machines and Power Electronics Group. A GE office has been set up within the University and will be staffed by three GE employees. The main focus of the ATG is to develop HV DC power converter technology for offshore renewable energy transmission networks. A framework agreement has been established for collaboration, with two PhDs being funded so far. 5. RESEARCH INTERESTS: 5.1 Current Research In renewable energy systems the engineering design challenges for generators and the power converter are dominated by the interaction between the generator, the prime mover and the resource, whilst providing an economically viable solution. Although I am an electrical engineer, my research interests are very much at the interface between electrical and mechanical engineering. With my team I have developed integrated electro-magnetic, structural and thermo-fluid design tools for both novel direct drive and more conventional generators. In addition, I have worked on the control of generators to optimize energy conversion in wind, wave and tidal current systems, and developed energy management control to optimize energy flows in hybrid wind-diesel-PV systems. All my research involves the experimental verification of design tools and models developed. A number of prototypes at 50kW or less have been successfully demonstrated, with two installed on commercially available wind turbines. The research has been funded through various sources: EPSRC, Carbon Trust, EU, Regional Development Agencies and industry. A table of all funding can be found in section 6. 5.2 Future Research Plans Intelligent Condition Monitoring: In the next 5-10 years reliability is one of the main challenges facing the offshore renewable energy industry. Condition monitoring systems are used in the wind industry, but only detect a failure and cannot determine the cause of the failure. The wind industry has historical data from onshore, but wave and tidal do not have such a database. Using the integrated design tool approach I intend to develop failure models of electrical components, and use these in conjunction with sensor networks to develop intelligent condition monitoring, so that a potential failure and its cause can be detected before the event occurs. This will allow technology operators to better plan O&M schedules, which is a major cost for offshore renewables. This work builds upon existing research through the use of the integrated design and modeling tools, and in particular an EPSRC grant under the UK-China programme. In addition, an EU FP7 grant has recently been submitted in a similar area. High Temperature Superconductor (HTS) Machines My current research into direct drive machines has led to a better understanding of how to reduce mass, ease manufacture and be more attractive for operation and maintenance. However there is a limit as to how much can be achieved with conventional technology, and these machines rely on rare earth based permanent magnets, the cost of which has increased by a factor of 5 in the last 10 years. HTS machines offer the greatest potential for gains in efficiency and reduction in physical size. Existing developments in HTS machines are based on incremental changes in conventional technology. Cooling HTS machines is difficult enough, but such incremental changes have led to additional engineering challenges. I have adopted an approach to develop a machine topology specifically to bypass these additional challenges. Some promising results have been obtained from 1 PhD, and GE has sponsored another PhD student. The University has provides some seed funding to build a small prototype, and GE have shown some interest in helping build a generator demonstrator. 5.3 Why is my research important? The UK government, Scottish government and EU have set challenging targets for electricity generation from renewables. The design of electrical generators is a key aspect to the development of optimised, efficient and cost effective renewable energy converters. My research is important because it has the potential to significantly improve reliability and hence reduce O&M costs compared to existing solutions, which utilise gearboxes and hydraulic systems to drive conventional high speed generators. Rapid and accurate design tools, which have been experimentally verified, are essential to enable industry to compare the options available. My research is leading the development of integrated design tools and has shown that if this approach is not adopted an uneconomic solution will be produced. In summary, my work into novel electrical machines and the development of integrated design tools is being used to address the challenges faced by the wind, wave and tidal energy technology developers. 6.

INTERNATIONAL COLLABORATION Within the UK my research on direct drive systems for wave and tidal devices is leading the way and has led to collaboration with colleagues at TU Delft, Uppsala University in Sweden, the University of Cassino in Italy, Sydney University of Technology and the National Cheng Kung University in Taiwan. These collaborations are in addition to those in EU projects. Specific collaborations include: TU Delft: Whilst at Durham University I co-hosted Dr. Henk Polinder from Delft, with Newcastle University, which led to a joint journal publication. In 2006 Dr. Polinder was a visiting researcher at Edinburgh, and my PhD student Alasdair McDonald spent 6 weeks working in Delft. This exchange has led to 6 conference papers, 2 of which were invited (IEMDC 07), and one was selected for a special edition of the IET Journal of Renewable Energy (EWEC 07). More recently another PhD student Aris Zavvos spent two weeks at Delft writing a journal paper with a PhD student at Delft. University of Cassino: In March 2004 I was invited by Dr. Fabrizio Marignetti at the University of Cassino to present four research seminars on my work. As a result of that visit I have been accepted as an external PhD supervisor on the Doctoral Program in Energy Systems at the Seconda Universita di Napoli (SUN). In 2006 I presented a series of seminars on microgeneration at SUN. A British Council grant was awarded in 2006 to enable an exchange between Cassino and Edinburgh, in which Prof. Marignetti and Dr. Vincenzo di Colli visited Edinburgh in July 2006, whilst Paul Stott spent 6 weeks in Cassino in May/June 2006 and April 2007. This exchange has led one conference paper, with a journal paper in preparation. Oregon State University (OSU): In May 2005 I visited OSU to explore collaboration in the area of wave energy research. Wave Energy is in the very early stages of development in the US, but OSU is leading the way in this field. OSU are an associate university partner in the Supergen Marine Phase 2 programme, and we are in discussions on a joint journal publication, which will involve a PhD student, Richard Crozier, visiting OSU in order to share information and results for the paper. CHINA – The recent award of an EPSRC grant under the British-China Collaboration Programme, due to start in October 2008, will lead to new collaborations with Chinese Academy of Sciences, University of Zhejiang, University of Sichuan, University of Tsingshua, Goldwind and GE Energy (Shanghai). Sydney University of Technology (Australia) and National Cheng Kung University (Taiwan) – after a Supergen Marine workshop held in Taiwan in August 2010 I have started to collaborate with Dr. Hsieh at NCKU on reliability of electrical machines, and specifically the impact of unbalanced magnetic pull (UMP) on bearing performance. A mutual colleague, Dr. Dorrell at SUT, has been brought into the collaboration as an expert in UMP and he has already collaborated with NCKU. So far the collaboration has led to my RA, Dr. Shek, visiting Australia in December 2010 and a conference paper presented at INTERMAG in Taiwan in April 2011. 9.
