• Coordinated Control of Multiple HVDC links using backstepping 

      Ersdal, Anne Mai; Imsland, Lars Struen; Uhlen, Kjetil (Journal article, 2012)
      This article regards a power system containing multiple High Voltage Direct Current (HVDC) links. The topic is to exploit the HVDC lines’ ability to control the power supplied by them to increase the stability of the system. ...
    • Methods for Ice-Model Updating Using a Mobile Sensor Network 

      Ersdal, Anne Mai (Master thesis, 2011)
      The need for dynamic positioning to function in ice-infested waters is growing as the offshore oil and gas industry enters the Arctic. The ice introduces great challenges, some of which can be resolved through proper ice ...
    • Model predictive load-frequency control 

      Ersdal, Anne Mai (Doctoral theses at NTNU;2017:48, Doctoral thesis, 2017)
      The decrease in frequency quality seen in the Nordic power system over the past two decades is a clear token of the major changes that power systems all around the world are facing. These changes are to a large extent ...
    • Scenario-based approaches for handling uncertainty in MPC for power system frequency control 

      Ersdal, Anne Mai; Imsland, Lars Struen (Journal article; Peer reviewed, 2017)
      A stochastic nonlinear model predictive controller (SNMPC) is designed for automatic generator control of a proxy of the Nordic power system, and it is compared with a multi-stage nonlinear model predictive controller ...
