Evaluation of small signal stability of a power system
Australian Journal of Electrical and Electronics Engineering, 2008In reality, a power system is never in steady-state, as there are persistent fluctuations in load levels with associated adjustments in generation. The growing complexity of power systems, as well as the system exposition to various contingencies, have exacerbated the system's steady-state condition.

Effect of PV and FACTS on Small Signal Stability
2018 20th National Power Systems Conference (NPSC), 2018Renewable Energy sources like Photovoltaic (PV) systems are available in present grids. Under small signal disturbances, the presence of PV affects the stability. In this paper both PV and various Flexible AC Transmission system (FACTS) devices has been added in a standard two area systems for stability studies.

Small Signal Stability of an Unregulated Power System
2007 Thirty-Ninth Southeastern Symposium on System Theory, 2007Small signal stability is the ability of the power system to maintain synchronism under small perturbations. Such perturbations occur continuously on the system because of the small variations in load and generation where the system continuously adjusts itself to changing conditions.

Neural network assessment of small signal stability
1994 Proceedings of Canadian Conference on Electrical and Computer Engineering, 1994Neural network (NN) techniques have been recently applied to several power system problems. So far the most common types of neural networks used in the power field have been the layered perceptron, trained with a backpropagation algorithm (supervised learning), and Kohonen's self-organizing feature maps (unsupervised learning).

Small-Signal Stability Analysis
1997Ever since Hendrik Bode of Bell Laboratories conceived and scribbled down the concept of the feedback amplifier on a page of the New York Times while going to work in the mid-1930s, applications of feedback contol theory and techniques have been found in almost every conceivable field of study.

Relationship of chaos and small signal stability region
Canadian Conference on Electrical and Computer Engineering 2004 (IEEE Cat. No.04CH37513), 2004In this paper, chaotic phenomena and its impact on the small signal stability region (SSSR) of power systems are studied. A typical period-3 trajectory in a simple power system is presented for the first time. Theorem Sarkovskii and Theorem Li-Yorke are used to identify the existence of chaos in power systems. This method can avoid the confusion caused

Neural Network Based Assessment of Small-Signal Stability
International Journal of Modelling and Simulation, 2007This paper presents a neural network (NN) based approach for the assessment of small-signal stability of single-machine infinite bus power system by predicting the modal components of the local mode. Two types of feedforward NNs were examined, namely, the radial basis function neural network (RBFNN) and back propagation neural network (BPNN). The input

An OPF Methodology to Ensure Small-Signal Stability
IEEE Transactions on Power Systems, 2011This paper presents a security redispatching procedure that allows achieving an appropriate security level in terms of small-signal rotor angle stability. The proposed methodology is based on an OPF problem that explicitly considers security limits through stressed loading conditions.
