Background and activities

Research areas

I am heading the research group "Electricity Markets and Energy Systems Planning" at the Department of Electric Power Systems at NTNU. My interests are especially focused towards integration of renewable energy in the energy system. My research activities includes:

  • Market design for power markets with variable renewable energy sources and storage
  • Optimization of energy storage and distributed flexible resources in connection with renewables (investment and operation)
    • Download my first Matlab-based simulation model here (still working!): Windhydtools
  • The use of hydro power as a balancing asset
  • Investment planning of grids, including a future North Sea Grid
  • Large scale integration of renewable energy sources in Europe
