- Profile
-
I am the Professor and Chair in Control and Power Systems at University of Sheffield. Currently, I hold the prestigious UKRI Future Leaders Fellowship 'Digitalisation of Electrical Power and Energy Systems Operation, MR/W011360/2, £1.5m', and the EPSRC New Investigator Award 'Grid flexibility through multiscale modelling and integration of power systems with electrified air transport, EP/W028905/1, £400k'.
My research experience covers power system operation and control, cyber-physical power systems, cybersecurity and resilience of power systems, real-time digital simulation, and grid integration with land-air transport electrification.
I lead the Control and Power Systems Laboratory (CAPS Lab) of University of Sheffield. At CAPS, we investigate digitalisation technologies that could potentially improve the monitoring and control of power grids in both cyber and physical aspects. We explore the advanced grid monitoring platform, state estimation techniques, cybersecurity strategy, contingency analysis, vulnerability assessment, and robust network control. At CAPS, we develop co-simulation platform for digital power grids, that enables the fundamental integration of cyber and physical simulators for the accurate, efficient and large-scale grid simulation. Our work involves the interfacing design for model-to-model integration of different complex networks, simulation synchronisation at various time steps, and advanced computing methods and algorithms to create a co-optimised analysis of cyber-physical power systems.
My industrial experience (2011-19) was gained from National Grid ESO as the GB Electricity System Operator, where I was professionally trained as a power system engineer in the real-time power system operation, mainly in the GB Electricity National Control Centre. My specific industrial expertise includes power system modelling and operational tools development for energy balancing and network control, to improve the security, resilience and economic operation of the GB power transmission systems.
