thyristor-controlled series compensator (tcsc) is one of the electric power lines series compensators. tcsc increases transmission system capacity and improves system dynamic and voltage stability. several controllers have been proposed, but most of them generally improve one of tcsc capabilities. in this paper a tcsc robust controller is designed based on nonlinear quantitative feedback theory...

Optimal supplementary damping controller design for Thyristor Controlled Series Compensator (TCSC) is presented in this paper. For the proposed controller design, a multi-objective fitness function consisting of both damping factors and real part of system electromachanical eigenvalue is used and RealCoded Genetic Algorithm (RCGA) is employed for the optimal supplementary controller parameters....

Appropriate models for voltage and angle stability studies are discussed in detail for the Static Var Compensator (SVC), the Thyristor Controlled Series Compensator (TCSC), the Static Va...

This paper presents the use of Self Adaptive Firefly Algorithm to identify the optimal placement of Thyristor Controlled Series Compensator (TCSC) in a power system network. The objective is to minimise the transmission loss in power system network with the placement of TCSC. To validate the proposed algorithm, simulations are performed on three IEEE test system using MATLAB software package. S...

In a deregulated electricity market, it may always not be possible to dispatch all of the contracted power transactions due to congestion of the transmission corridors. This paper presents a transmission lines congestion management in a restructured market environment using a combination of demand response and Thyristor controlled series compensators (TCSCs). The overall objective of FACTS devi...

This paper presents a new approach for the protection of Thyristor-Controlled Series Compensator (TCSC) line using Support Vector Machine (SVM). One SVM is trained for fault classification and another for section identification. This method use three phase current measurement that results in better speed and accuracy than other SVM based methods which used single phase current measurement. This...

TCSC (Thyristor-Controlled Series Compensator) has been used in modern power systems to increase power transfer and system stability. Besides, due to its controllable feature, TCSC has been used to work as a solution to sub-synchronous resonance (SSR) problems. However, it is not clear so far whether TCSC’s inherent characteristic can avoid SSR and its effectiveness for SSR damping. In this pap...
