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.

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
