Transient Energy of an Individual Machine PART I: Stability Characterization

open access: yesIEEE Access, 2021
The individual-machine-equal-area-criterion method already shows potential in the transient stability assessment of multimachine systems. This two-paper series systematically analyzes the transient characteristics of the system trajectory from a genuine ...

Direct evidence that density-dependent regulation underpins the temporal stability of abundant species in a diverse animal community

open access: yes, 2014
The authors thank the ERC (project no. BioTIME 250189) and the Royal Society for funding.To understand how ecosystems are structured and stabilized, and to identify when communities are at risk of damage or collapse, we need to know how the abundances of

Enhanced Transient Stabilization with Damping Assignment

open access: yesIFAC-PapersOnLine
The paper proposes an analytical nonlinear control approach for enhancing the transient performance of lossy multi-machine power systems. The prominent feature of this approach lies in the inclusion of damping assignment, whereby the oscillation of the power system frequency is dampened out more effectively.

Power system transient stability analysis of stiff systems using the Multirate method

open access: yes, 2011
Power system transient stability studies are complex and can take a substantial amount of time to simulate. The Multirate integration method is one way to speed up simulation studies.

Non-Normal Dynamic Analysis for Predicting Transient Milling Stability

open access: yes, 2018
A transient milling stability analysis method is presented based on linear dynamics. Milling stability is usually analyzed based on asymptotic stability methods, such as the Floquet theory and the Nyquist stability criterion.
