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

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.

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

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.

Probabilistic Analysis of Power System Small Signal Stability Region
2005 International Conference on Control and Automation, 2005With the deregulation of power industry in many countries, the traditionally vertically integrated power systems have been experiencing dramatic changes leading to competitive electricity markets. Power system planning in such an environment are now facing increasing requirements and challenges because of the deregulation. The traditional deterministic

Small Signal Stability of UHVDC Hierarchical Connection to AC Grid
TENCON 2018 - 2018 IEEE Region 10 Conference, 2018UHVDC hierarchical connection to AC grid is a specially-designed mode in China to enhance the support from the receiving AC grid to HVDC. Besides the merits to optimize power flow, such a connection mode features stronger stability than the mode in which all power is fed into the grid with a single voltage grade.
