Summary

 

Summary

My  research focuses on the analysis and technology to develop a zero carbon electricity supply system that is able to accommodate variable renewable sources and new widespread electric vehicle charging while still delivering a cost effective and very reliable service. My research specialisation is in power electronics for use in power systems and presently I focus on the control, stability and protection of power systems with very high penetration of inverter-based resources.

Previously, I contributed  converter designs for HVDC that reduce losses while also providing control functions assist AC system integration and, in distribution networks, pioneered the use of soft open points and the study of stability of microgrids.

My work has been supported by EPSRC, Hitachi Energy, National Grid ESO and UK Power Networks.

I teach an introductory module in power engineering to Electrical and Electronic Engineering students and parts of specialist Masters modules

I am a fellow of the Royal Academy of Engineering, the Institute of Electrical and Electronics Engineers, the Institution of Engineering and Technology and the Chinese Society for Electrical Engineering.
