An Improved Power System Transient Stability Prediction Model Based on mRMR Feature Selection and WTA Ensemble Learning
TL;DR: An improved high accuracy power system transient stability prediction model is proposed, based on min-redundancy and max-relevance (mRMR) feature selection and winner take all (WTA) ensemble learning, which can provide a basis for the future emergency control decision-making of power systems.

Modal based stability analysis of power systems using energy functions
TL;DR: In this paper, a physically based decomposition technique is exploited to perform direct stability analysis of power systems using the energy function method, which decomposes the system into r areas associated with (r- 1) slow modes of the linearized system.
Journal ArticleDOI
A comparison of dynamic security indices based on direct methods
TL;DR: This paper reformulates the various Lyapunov energy functions and stability criteria for the direct methods proposed in the literature in a unified mathematical notation and restated each type of stability criterion in terms of a threshold value, TH.

Analysis of robust transient stability of power systems using sum of squares programming
TL;DR: In this paper, a polytopic representation for the uncertain parameters and a concept from the field of robust control are used to solve the analysis problem of robust transient stability of power systems with uncertain parameters.

A review of dynamic security indices based on direct methods
TL;DR: This paper gives a comparison of various performance indices and criteria used in power system stability analysis by first recasting the performance indices, and their underlying system models, in a unified notation and then identifying all the salient features of the mathematical models.

A Practical Method for the Direct Analysis of Transient Stability
T. Athay,R. Podmore,S. Virmani +2 more
TL;DR: In this paper, the authors describe the development and evaluation of an analytical method for the direct determination of transient stability, which is based on the analysis of transient energy and accounts for the nature of the system disturbance as well as for the effects of transfer conductances on systenmbehavior.

Stability regions of large-scale systems
TL;DR: In this article, three different forms of Liapunov functions are used for describing the stability behavior of the aggregated system, but one form in particular, heretofore not used in this context, is found to be the most natural.

Characterization of Equilibrium and Stability in Power Systems
TL;DR: In this paper, the center of angle is defined as the inertia weighted average of all rotor angles and the angular velocity of the centre of angle accurately describes the frequency of the system.

Coherency based decomposition and aggregation
TL;DR: Coherency with respect to a set of slowest modes and an earlier developed grouping algorithm are used to identify weakly coupled areas, as demonstrated on a 48-machine model of the United States North-East power system.
