Power System Coherency Identification Using Nonlinear Koopman Mode Analysis
In this thesis, we apply nonlinear Koopman mode analysis to decompose the swing dynamics of a power system into modes of oscillation, which are identified by analyzing the Koopman operator, a linear infinite-dimensional operator that may be defined for any nonlinear dynamical system. Specifically, …

MULTI-OBJECTIVE GLOBAL OPTIMISATION FOR THE OPERATIONAL ECONOMICS AND SECURITY OF THE INTERCONNECTED AND LONGITUDINAL SYSTEM
… curve technique which is usually unreliable for coherency identification, the approach proposed is based on the examination of mode shapes, and can easily derive insight from mode shapes for nonstate variables P (real power). This methodology is very useful, not only for evaluating the best …

A Local Measurement Based Protection Methodology for Initiating Controlled Islanding in Power Systems
… of dynamic system equivalents after generator coherency determination followed by further sophisticated calculation. The proposed methodology simplifies the real-time procedure of initiating controlled islanding by using a local measurement-based generator out-of-step (OOS) protection along …
