Eigenvalue Tracking of Large-Scale Systems Impacted by Time Delays
Andreas Bouterakos, Georgios Tzounas
The paper focuses on tracking eigenvalue trajectories in power system models with time delays. We formulate a continuation-based approach that employs numerical integration to foll…
On the Eigenvalue Tracking of Large-Scale Systems
Andreas Bouterakos, Joseph McKeon, Georgios Tzounas
The paper focuses on the problem of tracking eigenvalue trajectories in large-scale power system models as system parameters vary. A continuation-based formulation is presented for…
Stability of the Theta Method for Systems with Multiple Time-Delayed Variables
Andreas Bouterakos, Georgios Tzounas
The paper focuses on the numerical stability and accuracy of implicit time-domain integration (TDI) methods when applied for the solution of a power system model impacted by time d…
Smooth Rate Limiter Model for Power System Stability Analysis and Control
Zaint A. Alexakis, Panos C. Papageorgiou, Antonio T. Alexandridis +2
The letter proposes a smooth Rate Limiter (RL) model for power system stability analysis and control. The proposed model enables the effects of derivative bounds to be incorporated…
Instantaneous Frequency Estimation in Unbalanced Systems Using Affine Differential Geometry
Ali Alshawabkeh, Georgios Tzounas, Angel Molina-Garcia +1
The paper discusses the relationships between electrical and affine differential geometry quantities, establishing a link between frequency and time derivatives of voltage, through…
Instantaneous Power Theory Revisited with Classical Mechanics
Federico Milano, Georgios Tzounas, Ioannis Dassios
The paper revisits the concepts of instantaneous active and reactive powers and provides a novel definition for basic circuit elements based on quantities utilized in classical mec…
