Dynamic stability enhancement of power system using fuzzy logic based power system stabilizer
2013 International Conference on Power, Energy and Control (ICPEC), 2013The power system is a dynamic system and it is constantly being subjected to disturbances. It is important that these disturbances do not drive the system to unstable conditions. For this purpose, additional signal derived from deviation, excitation deviation and accelerating power are injected into voltage regulators.

Dynamic Stability Enhancement of Power System Using Intelligent Power System Stabilizer
2014The destabilizing effect of high gain in voltage regulators persists in power system. The power oscillations of small magnitude and high frequency, which often persisted in power system, present the limitation to the amount of power transmitted within the system. In this paper, a linearized Heffron–Phillips model of a single machine infinite bus (SMIB)

Relative Dynamic Stability Regions of Power Systems
IEEE Transactions on Power Apparatus and Systems, 1970In this paper, making use of the well-established linearized equations of the synchronous machine and its control equipment, the characteristic equation of the system is developed. Using this characteristic equation, relative dynamic stability regions are mapped in the regulator parameter plane.

Power system dynamic load identification and stability
PowerCon 2000. 2000 International Conference on Power System Technology. Proceedings (Cat. No.00EX409), 2002Proper power system load models are playing more important roles in power system stability analysis in today's stressed power systems. Different load models may cause a large difference in stability analytical results. Measurement based load modeling gives a closer look at the real power system loads and their dynamic characteristics.

Improved Dynamic Load Model for Power System Stability Studies
IEEE Power Engineering Review, 1982The behavior of the load model in power system stability studies has been shown by various investigators to be a very important factor in determining the stability of power system elements. Load models which are presently available in typical stability programs make it difficult if not impossible to model the actual dynamics of power system load ...
