AN ADAPTIVE POWER SYSTEM STABILIZER
IFAC Proceedings Volumes, 1988This paper presents an adaptive power system stabilizer utilizing the eigenvalue control strategy. The control algorithm is based on the identification of decoupled subsystem model parameters in real-time from local measurements only. The concept of decentralized stabilization of power system electromechanical oscillatory modes is discussed and control

AN ADAPTIVE POWER SYSTEM STABILIZER
IFAC Proceedings Volumes, 1987Abstract The evolution of the adaptive control concept in which a controller continuously tunes itself to the changing plant characteristics, has provided an attractive design alternative to the conventional approach. A microcomputer based power system stabilizer using the self-tuning adaptive control concept is described in this paper. The recursive

An Improved Genetic Algorithm based Power System Stabilizer for power system stabilization
2019 IEEE AFRICON, 2019This paper considers the damping of the local-mode power system oscillation using Lead-Lag power system stabilizer (PSS). Thus, a simple single-machine infinite-bus power system is used. The Lead-Lag PSS parameters are tuned using Genetic Algorithm Optimization (GAs). Simulation results are presented with and without the proposed controller.

Survey of supervisory power system stabilizers for enhancement of power system stability
2007 42nd International Universities Power Engineering Conference, 2007The weak performance of conventional power system stabilizers to damp inter-area oscillations during severe disturbances can cause the power systems to lose stability especially if the systems are highly oscillatory. To ensure small-signal stability of the systems, increasing interest has been focused on developing supervisory power system stabilizers (

Enhancement of transient stability on power system with the use of power System stabilizers
2016 International Conference on Electrical, Electronics, and Optimization Techniques (ICEEOT), 2016As we all know that most of the power systems are interconnected through long distance tie lines, in order to transfer a large amount of electric power. There are some constraints which affect to build new transmission lines, which are: limited availability of resources, strict environment and shortage of funds.

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)
