Complex power networks, especially those with high dependency on power electronic converters, are vulnerable to stability and power quality issues.

Classic damping techniques exceed allowable weight / volume limits, and only offer stability support, and so alternative solutions are required. Energy storage can be configured to undertake multiple power network functions, with each function having a set priority level.

Key challenges exist to exploit fully the power management capability enabled by energy storage systems in power networks:

  • Examine control methods for both the AC grid and the battery system
  • Devise algorithms to optimise the multi control functions
  • Energy storage system control based on campus-wide power network data acquisition 

Research focus

Key applications

  • AC power networks, including smart grids:
    • Spinning reserve, power smoothing, automatic generator control, frequency regulation, power system stabiliser, VAR support
  • On-board aircraft DC power networks:
    • Load smoothing and voltage support during generator faults / reconfiguration events
  • Plug-in hybrid or battery electric road / water vehicles:
    • DC voltage regulation

Collaboration with industry

Energy storage system integration and usage on AC power networks is the focus of an Innovate-UK research project in collaboration with Upside Energy and Sharp.
