Design and Operation Investigations for large Converter-Fed Synchronous Machines in Hydropower Applications
(Doctoral theses at NTNU;2019:194, Doctoral thesis, 2019)The work presented in this thesis deals with design and operation investigations for large converter-fed synchronous machines in hydropower applications. It is shown that the optimal rated frequency that gives the lowest ... -
Modelling of frequency-coupled power electronics systems: Automated model generation and chirp frequency scanning, applied to single-phase VSCs
(Doctoral theses at NTNU;2024:138, Doctoral thesis, 2024)Power electronics converters play a major role as interface to the AC grid as we transition towards an electric and renewable society. The converters are controlled, modelled and generally understood in time-periodic ... -
Optimization of Energy Storage for Frequency Control in Autonomous AC Power Systems – Frameworks for Planning and Operation
(Doctoral theses at NTNU;2023:144, Doctoral thesis, 2023)AC power systems have been designed to balance active power from the generation side, adopting technologies that offer three important properties: dispatch capability, ability to participate in frequency control, and large ...
