I joined the College of Engineering at Swansea University after six years of work in the power industry with the aim to use my experience to solve the challenges related to the integration of power electronics devices in the transmission and distribution systems.

The research topics I am working on include:

  • Development of advanced control systems to provide robust and reliable operation of power-electronics devices, and study of the interaction of these devices with the power system
  • Development of ancillary functions which help to support grid operation, including reactive power injection, power oscillation damping and harmonic filtering.
  • Assessment of the impact of harmonic components on power measurements

The tools used to perform my research include computer simulations, laboratory testing and field testing. 

Technical Expertise:

Power systems

Modelling and simulations of power systems for steady-state and transient analysis, power systems studies including TRV analysis, harmonic analysis, insulation coordination, power flow, network reduction, network impedance plots for harmonic filter design

Power Electronics and Controls

Development of control and protection functions for power-electronics based devices, use of Matlab toolboxes toprogram hardware equipment, laboratory testing of control and protection functions with real-time simulator

Renewable energies

Modelling of wind turbines and solar inverters for power systems studies, studies of interactions between distributed resources and the power system

Power Quality

Study of harmonic phenomena for power systems: harmonic filter design, harmonic performance and rating studies, spectral analysis of waveforms, effect of resonance on harmonic amplifications, power quality measurements    

Areas of Expertise

  • power systems analysis
  • renewable energy
  • power electronics
  • power quality
