System design and control

Fully exploiting the high charge / discharge rates offered by electrical energy storage elements, including supercapacitors and electrochemical batteries, is only achieved through bespoke system design. Energy storage system are based on the latest power devices, and make use of advanced manufacturing techniques to develop robust, highly efficient systems.


Key challenges exist to exploit fully the potential of energy storage systems in power networks:

  • Devising controllers to use effectively the energy storage capacity
  • Develop highly efficient systems
  • Developing power electronic interface converters which match the fast charge / discharge rates of the energy storage element.

Research focus

  • Multi-input supervisory controller design
  • Low-level converter control design
  • Control hardware-in-the-loop (HIL) using a Typhoon HIL 600
  • Power-dense converter design / manufacture / test
  • Use of different energy storage elements (supercapacitors or electrochemical batteries)

Key applications

  • Complex DC power networks on-board the more electric aircraft
  • Plug-in hybrid or battery electric vehicles
  • Public transport vehicles (bus / tram / train)
  • Passenger and commercial marine vessels
  • Land-based smart grids
  • AC land based power networks

Collaboration with industry

Energy storage system design and control is an important enabling technology for many low carbon energy and transport systems. Our research includes work with Rolls-Royce plc and a recently funded Innovate-UK grant in collaboration with Mallaghan and Lyra Electronics
