Personal profile
Personal Statement
I joined the University in 2013 and is currently a Professor in the Department of Electronic and Electrical Engineering. I received my PhD in Electrical engineering from University of Sheffield in 2000 and started my career with ALSTOM, developing VSC based HVDC systems. My main research interests and experiences are in the areas of power electronics, converter control for grid connection of renewables, control and operation of HVDC systems and stability of power network with large converter penetration. I have published over 200 journal and conference papers and received the 2013 IET Renewable Power Generation Premium Award for my published paper “DC voltage control and power dispatch of a multi-terminal HVDC system for integrating large offshore wind farms”.
