• Achieving Enhanced Phasor POD Performance by Introducing a Control-Input Model 

      Haugdal, Hallvar; Uhlen, Kjetil Obstfelder; Jóhannsson, Hjörtur (Chapter, 2023)
      In this paper, an enhancement to the well known Phasor Power Oscillation Damper is proposed, aiming to improve its performance. Fundamental to the functioning of this controller is the estimation of a phasor representing ...
    • Estimation of Oscillatory Mode Activity from PMU Measurements 

      Haugdal, Hallvar; Uhlen, Kjetil; Müller, Daniel; Jóhannsson, Hjörtur (Chapter, 2020)
      We propose a method for estimating the activity of oscillatory modes in power systems. The frequencies and mode shapes of the modes of interest are assumed to be known beforehand, either from linear modal analysis or from ...
    • An Open Source Power System Simulator in Python for Efficient Prototyping of WAMPAC Applications 

      Haugdal, Hallvar; Uhlen, Kjetil Obstfelder; Jóhannsson, Hjörtur (Chapter, 2021)
      An open source software package for performing dynamic RMS simulation of small to medium-sized power systems is presented, written entirely in the Python programming language. The main objective is to facilitate fast ...
