A new metaheuristic method, the BAT search algorithm based on the echolocation behaviour of bats is proposed in this paper for optimal design of Power System Stabilizers (PSSs) in a multimachine environment. The PSSs parameter tuning problem is converted to an optimization problem which is solved by BAT search Algorithm. An eigenvalues based objective function involving the damping factor, and ...

In this paper, tuning of power system stabilizer (PSS) and thyristor controlled series capacitor (TCSC) is studied. The analysis of mode controllability is used to select the effective location for TCSC. The performances of TCSC equipped with a proportional-integral-derivative controller (P-I-D controller) and proportional-integral-derivative power system stabilizer (P-I-D PSS) are investigated...

Power system Stabilizers are used in order to damp out the low frequency oscillations which are due to disturbances. This paper attempts to investigate the performance of Conventional Power System Stabilizer (CPSS), Fuzzy Logic Power System Stabilizer (FLPSS) and Artificial Neural Network based Power System Stabilizer (ANNPSS) under Prefault and Postfault conditions for different loadings. The ...

Electromechanical oscillations in a power system often exhibit poor damping when the power transfer over a corridor is high relative to the transmission strength. Traditional approaches to aid the damping of power system oscillations include the use of Power System Stabilizers (PSS). Power system stabilizers are used to generate supplementary control signals for the excitation system in order t...

Fuzzy logic has emerged as a promising tool for several power system applications. A large body of the literature in this area is concerned with the stability of the electric power system and considerable effort has been directed to the development of a fuzzy logic based power system stabilizer (FLPSS). The purpose of this paper is to present an overview of the FLPSS, based on published literat...

This paper proposes a genetic algorithm based method to tune the parameters of a proportional plus integral plus derivative (PID) power system stabilizer (PSS). A classical parameter optimization approach is integrated within the genetic search process. To assess the quality of system dynamic performance a quadratic performance index is adopted within the tuning process. To enhance the overall ...

Power system stabilizers (PSSs) are added to excitation system to enhance the damping during low frequency oscillations. This paper presents a study of fuzzy logic power system stabilizer (PSS) for stability enhancement of a single machine power system. In order to accomplish the stability enhancement, speed deviation (Δω) and acceleration (Δπ) of the rotor of synchronous generator of Kota Ther...

In the previous studies the effect of Static Var Compensator (SVC) and Power System Stabilizers (PSS) has not been considered specially for various faults in a three phase system. For improvement in inductive and capacitive power flows Shunt Flexible AC Transmission System (FACTS) devices can be used and when they are placed in the center of transmission line of a electrical power transmission ...
