Prof Stephen Finney

Electronic and Electrical Engineering

Personal statement

Stephen Finney graduated with a first class degree from Loughborough University in 1988. He worked for the electricity supply industry before undertaking a PhD in power electronics at Heriot-Watt University. He obtained his PhD in 1994. Since then his work in the area of power electronics has resulted in the publication of over 80 research papers and the supervision 10 PhD completions.

He is now Professor with the power electronics, drives and energy conversion group at the University of Strathclyde. This research group includes 4 academic staff, seven postdoctoral research fellows and 20 postgraduate researchers. Research themes include power semiconductor devices, circuits and applications, power electronics in high power systems and energy conversion systems for grid interface/power quality applications.

His research group has developed significant expertise in the application of power electronic systems to electrical generation, transmission and distribution. Work in this field includes HVDC transmission, Multi-terminal HVDC, Renewable generator interface and Energy collection architectures.

In addition to academic research Dr Finney has been involved in a number of successful industrial collaborations. These have ranged from the development of high performance switch mode amplifiers, to the design and commissioning of high power Locomotive drive units. In 2010 he was part of the team which contributed to the ETI funded ‘Network Capacity Study’. Over 2013-2014 his team have been working on industrial funded program to assist the development of HVDC protection systems; In 2015 they will start work (Alongside Warwick and Cambridge Universities and industrial partners ) on project to develop high capacity, low loss power modules for HVDC applications.

300 kVA Three-Phase Hybrid Generator - Testing and Investigation on the Performance of a
Zafar, Jawwad (Co-investigator) Finney, Stephen (Principal Investigator)
The hybrid generator (HG) technology is offered as a solution for off-grid power supply requirements in remote locations and can be used to provide power for residential, construction, telecom towers and disaster relief applications. The HG is a combination of a diesel generator (DG) and a power-electronic converter with integrated battery storage, which is promoted as leading to a significant fuel saving. In conventional generator-only applications, the diesel generator must “load follow” and therefore operates at off-optimal conditions for the vast majority of time. In the HG, the battery system alleviates the “load follow” requirement. Other benefits include no noise when operating in battery-only mode, less carbon emissions through operation of the DG at optimal conditions and use of battery, generally more efficient operation of the DG and reduced cost of ownership since the hours of operation of the diesel engine are reduced. Wind and solar energy can be added as secondary sources to the HG. Furthermore, the unit can have an auxiliary AC input that allows charging of batteries at times (e.g. overnight) when the grid-sourced electricity may be cheaper.

Virtual Electric - Extended Zero Emissions (EZE) Hybrid Bus
Zafar, Jawwad (Co-investigator) Melone, Joseph (Co-investigator) Finney, Stephen (Principal Investigator)
This project is funded by the Scottish Enterprise. In addition to being the PNDC/UoS activities coordinator for the 'Virtual Electric - Extended Zero Emissions (EZE) Hybrid Bus' project with Alexander Dennis, I am also responsible for the delivery of 02 work packages apart from instrument specification, equipment installations, PR events and participation in bi-weekly meetings. This has resulted in the installation of a 100 kW wireless charger at PNDC (the first of its kind in Scotland). The project partners are Alexander Dennis Ltd (ADL), BAE Systems (Operations) Ltd, Axeon Power Ltd and Scottish and Southern Energy (SSE) plc while the project values is above £0.32 Million (for UoS).

16 kVA Single-Phase Hybrid Generator - Testing and Investigation of the Performance of a
Zafar, Jawwad (Co-investigator) Finney, Stephen (Principal Investigator)
The hybrid generator (HG) technology is offered as a solution for off-grid power supply requirements in remote locations and can be used to provide power for residential, construction, telecom towers and disaster relief applications. The HG is a combination of a diesel generator (DG) with integrated battery storage and a power-electronic converter, which is promoted as leading to significant fuel saving [2]. In conventional generator-only applications, the diesel generator must “load follow” and therefore operates at off-optimal conditions for the vast majority of time – the battery system alleviates this requirement. Other benefits include low/no noise through noise insulation and operation in battery-only mode, less carbon emissions through operation of the DG at optimal conditions and use of battery, generally more efficient operation of the DG and reduced cost of ownership since the engine has to run less often. Wind and solar energy can be added as secondary sources to the HG. Furthermore, the unit can have an auxiliary AC input that allows charging of batteries at times (e.g. overnight) when the grid-sourced electricity may be cheaper. Modularity is another advantage that allows deployments to be scaled up through use of multiple units.
