IES Seminar: Marios Sousounis, Leong Kit Gan, Ikhwan Ridzuan


Rm D/E, Alrick Building, Kings Buildings


Friday, February 28, 2014 - 13:00 to 14:00

Marios, Leong Kit and Ikhwan are second year PGs at IES. Come along to hear about their research projects.

Marios Sousounis

Abstract: In order to optimise a tidal energy conversion system operation, maintenance and power generation aspects have to be taken into account. As a result alternative methods of implementing a tidal energy conversion system are investigated compared to the already established ways introduced in wind energy systems. The generator power output can be optimised by utilising variable-speed control strategies allowing the system to operate at maximum power coefficient while availability can be increased by reducing the components installed offshore by using long three-phase cables between the generator and onshore voltage source converters. The tidal current energy conversion system is investigated by developing a full resource-to-grid model in MATLAB/Simulink and by performing system analysis regarding the effects of harmonics and overvoltages associated with the long transmission cables.

Bio: Marios Charilaos Sousounis received his degree in Electrical Engineering and Computer Science from NTU Athens in 2011 and his M.Sc. from the University of Edinburgh in 2012. Now he works towards his PhD and his research interests cover fault tolerant control, offshore systems and optimisation of renewable energy systems.

Leong Kit Gan

Abstract: Lack of affordable and reliable electricity supply is a major impediment to the development of many rural communities, particularly those remote from the existing electricity grid. This is especially true in developing countries, where off-grid systems are often only a practical solution for electricity generation. Traditionally, off-grid systems were based solely on diesel generators, but significant rise of oil prices has made diesel-based systems uneconomic.
The PhD project is focused on the detailed design, build and test of a hybrid wind-diesel system for off-grid applications using Gaia's fixed speed wind turbine technology. Within the project, the optimum sizing of hybrid system, power converter topologies and potential control strategies will be explored. Both modelling and experimental work will be involved in this project, with the latter to verify the former.

Bio: Leong Kit Gan graduated with Bachelor of Electrical & Electronics
Engineering (Hons.) from University Tenaga Nasional, Malaysia in 2009. He then worked for Altera as a Test Development engineer, developing test programmes and performing silicon debugging for field-programmable gate array (FPGA). In 2010 he joined Motorola as an Analogue Design engineer, designing radio systems. Leong Kit graduated with MSc in Sustainable Energy Systems in 2012 from The University of Edinburgh. He is currently pursuing his PhD in Hybrid Wind-Diesel System in the same university.
