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 ... -
Application of Phasor Measurements for Online Monitoring and Adaptive Damping Control of Electromechanical Oscillations
Haugdal, Hallvar (Doctoral theses at NTNU;2022:230, Doctoral thesis, 2022)Power systems are large and complex systems consisting of thousands of components, like generators, transformers and transmission lines, which function together to ensure that the voltage and frequency are close to the ... -
Comparison of Voltage Stability Indices Based on Synchronized PMU Measurements
Rodrigues de Brito, Hugo; Uhlen, Kjetil Obstfelder (Chapter, 2023)The need for reliable information about the status of electrical power systems is an increasingly relevant concern within the current trend of electrification and deployment of power electronics-based devices. In this ... -
Investigations on Secondary Voltage Control for Long-Term Reactive Power Management
Rodrigues de Brito, Hugo; Monteiro de Souza, Valeria; Uhlen, Kjetil Obstfelder (Chapter, 2023)Voltage and reactive power management is a crucial task for system operators worldwide, and particularly in Norway. While manual operations within regional control cen-ters were once the norm, a major shift is currently ... -
A Novel Phasor Power Oscillation Damper With Adaptive Phase Compensation, Achieved Using Multiple Model Adaptive Estimation
Haugdal, Hallvar; Uhlen, Kjetil Obstfelder; Johannsson, Hjortur (Peer reviewed; Journal article, 2023)In this paper, an adaptive version of the well known Phasor Power Oscillation Damper is presented. The proposed controller is adaptive in the sense that the phase compensation between the measured input and the applied ... -
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 ... -
Optimal and Adaptive Arming of System Protection Schemes
Baltensperger, Daniel Simon (Doctoral theses at NTNU;2023:437, Doctoral thesis, 2023)A dependable power supply is critical to the well-being of today’s society. According to forecasts, this issue will become increasingly relevant and pose numerous challenges that need to be faced. The energy demand is ...
