A very important matter of discussion in power system operation is the oscillations damping problem. As an issue, new more effective power system stabilizers (PSSs) have been implemented, based on non linear control laws and/ or non conventional control techniques such as those provided by use of fuzzy logic and neural networks. Because of simultaneous presence of several PSSs in the power syst...

The paper considers simultaneous placement and tuning of power system stabilizers for stabilization of power systems over a wide range of operating conditions using genetic algorithm. The power system operating at various conditions is considered as a finite set of plants. The problem of setting parameters of power system stabilizers is converted as a simple optimization problem which is solved...

This paper investigates the enhancement of power system stability via coordinated design of Power System Stabilizers (PSSs), Thyristor Controlled Series Capacitor (TCSC)-based stabilizer, and Static Var Compensator (SVC)-based stabilizer in a multi-machine power system. The design problem of the proposed stabilizers is formulated as an optimization problem. Using the developed linearized power ...

Power system stabilizers (PSSs) are used to enhance the damping during low frequency oscillations. Artificial intelligence techniques provide one alternative for stability enhancement and speed deviation (Δw). In this paper we have applied Fuzzy based and Support Vector Machine (SVM) based approach to PSS for Single Machine Infinite Bus (SMIB) System .The proposed method using SVM techniques ac...

A new algorithm for the design of decentralized output feedback stabilizers for large-scale electric power systems is presented in this paper. In the proposed approach, the generators which are most effective for stabilizer applications are first identified by using participation factors. Then an efficient algorithm based on decentralized pole assignment is proposed for the determination of the...

this paper presents a new modified shuffled frog leaping algorithm (msfla) applied to design simultaneous coordinated tuning of damping controllers to damp the power system low frequency oscillations. for this, a new frog leaping rule is proposed to improve the local exploration and performance of the original sfla and the genetic mutation operator is employed for new frog generation instead of...

Power system stability enhancement via a power system stabilizer (PSS) and FACTS-based stabilizers is thoroughly investigated in this paper. The design problem of PSS and different FACTS controllers is formulated as an optimization problem. An eigenvalue-based objective function to increase the system damping and improve the system response is proposed. Then, a real-coded genetic algorithm (RCG...
