This paper presents a framework to carry out an novel method based Optimal Power Flow (OPF) for transmission congestion management in deregulated power system using Thyristor Controlled Series Capacitor (TCSC) and Generation Rescheduling. In the deregulated environment, some generators may not be willing to participate in the congestion management process for their own economic interest or some...

in this paper, the performance of two types of facts devices in order to enhance the power system static voltage stability has been investigated. these devices include static var compensator (svc) and thyristor controlled series capacitor (tcsc). the modeling of the single machine infinite bus (smib) and aforesaid devices has been made up in steady state mode with disregarding of the generator ...

Rapid industrial development and innovations in technology bring about the menace of congestion deregulated power systems (DPS). The transmission lines are continuously working under a stressed condition with reduced transfer capacity. In this situation, losses voltage deviations at load buses increased hence reduce system stability. To mitigate congestion, improving available capability (ATC) ...

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...

Power System Stabilizers (PSS) are generally employed to damp electromechanical oscillations by providing auxiliary stabilizing signals to the excitation system of the generators. But it has been found that these Conventional PSS (CPSS) do not provide sufficient damping for inter-area oscillations in multimachine power systems. Thyristor Controlled Series Capacitor (TCSC) has immense potential ...

This paper focuses on multi-objective designing of multi-machine Thyristor Controlled Series Compensator (TCSC) using Strength Pareto Evolutionary Algorithm (SPEA). The TCSC parameters designing problem is converted to an optimization problem with the multi-objective function including the desired damping factor and the desired damping ratio of the power system modes, which is solved by a SPEA ...
