Dominant Modes Identification of Linear Systems via Geometrical Search
Semlyen, Adam; Ramirez, Abner; Gustavsen, Bjørn; Iravani, Reza (Peer reviewed; Journal article, 2020)This paper presents a novel approach, based on the theory of hyperplanes, for mode identification of linear systems. The proposed approach can operate on either a set of ordinary differential equations (converted to diagonal ... -
Inclusion of Neutral Points in Measurement-Based Frequency-Dependent Transformer Model
Gustavsen, Bjørn (Peer reviewed; Journal article, 2021)Measurement-based wide-band black-box transformer models are well suited for simulation studies of high-frequency transients in power systems. The inclusion of neutral points in such models can be difficult when the model ... -
Measurement-based frequency-dependent model of a HVDC transformer for electromagnetic transient studies
Gustavsen, Bjørn; Vernay, Yannick (Peer reviewed; Journal article, 2020)A wide-band, frequency-dependent five-terminal model is developed that represents one HVDC transformer unit in the French-English IFA2000 HVDC interconnection. Three such interconnected 1-ph units constitute one 3-ph ... -
Neutral Point Overvoltages in Wye-Wye Connected Distribution Transformer Caused by Lightning Current in Low-Voltage Winding
Gustavsen, Bjørn; Longva, Kårstein (Peer reviewed; Journal article, 2020)Lightning strokes is a main source of transformer failures in distribution systems. The discharge of a lightning current through a distribution transformer's high-voltage (HV) side arresters leads to a ground potential ... -
Passive Filter Design Algorithm for Transient Stabilization of Automotive Power Systems
Baumann, Martin; Abouzari, Ali Shoar; Weissinger, Christoph; Gustavsen, Bjørn; Herzog, Hans-Georg (Chapter; Peer reviewed, 2021)The automotive power system is being increasingly expanded by adding high-dynamic power electronics. These components can potentially cause malfunction or failure of safety-relevant low-voltage components. The susceptibility ... -
Passivity assessment and enforcement utilizing eigenpairs information
Gustavsen, Bjørn (Peer reviewed; Journal article, 2021)Rational models can be a cause of unstable time domain simulations if they are non-passive. One commonly applied method for ensuring model passivity is to combine a passivity assessment step with a passivity enforcement ... -
Passivity Enforcement by Residue Perturbation via Constrained Non-Negative Least Squares
Gustavsen, Bjørn (Peer reviewed; Journal article, 2020)Passivity is a fundamental requirement for rational models to guarantee stable behavior when included in general time domain simulations. This paper introduces a new variant of one passivity enforcement scheme that is based ...
