In recent years, studies have been investigated the effectiveness of UPFC and TCSC in increasing power transfer capability. However, the effectiveness of these FACTS devices in increasing power transfer capability when the load is non-linear has not been established in a comparative study yet. This paper will explore the steady-state performance of the UPFC and TCSC as impedance compensation mo...

This paper focuses on the optimal power flow solution and the enhancement of the performance of a power system network. The paper presents a secured optimal power flow solution by integrating Thyristor controlled series compensator (TCSC) with the optimization model developed under overload condition. The Teaching Learning Based Optimization (TLBO) has been implemented here. Recently, the oppos...

With constraints on data availability and for study of power system stability it is adequate to model the synchronous generator with field circuit and one equivalent damper on q-axis known as the model 1.1. This paper presents a systematic procedure for modelling and simulation of a single-machine infinite-bus power system installed with a thyristor controlled series compensator (TCSC) where th...

 یکی از دلائل بروز نوسان‌های فرکانس پایین1 در سیستم‌های قدرت، کمبود گشتاور میرا کننده به منظور غلبه بر اغتشاشات موجود در سیستم‌های قدرت است. در گذشته پایدارساز سیستم قدرت2  برای میرا نمودن نوسان‌های فرکانس پایین استفاده می شد. ادوات FACTs3 از قبیل جبران ساز سری کنترل شونده با تریستور4 (TCSC) توانایی کنترل توان، کاهش تشدید زیرسنکرون و افزایش پایداری گذرا را دارا هستند. TCSC را می‌توان برای میرا ...

In this paper, a new procedure to design Supplementary Damping Controllers (SDCs) for Flexible Alternating Current Transmission System (FACTS) devices is proposed. The control design problem is formulated as a search for a feasible controller subject to restrictions in the form of Linear Matrix Inequalities (LMIs). The main objective, from the application viewpoint, is the improvement of the da...

A fuzzy-controller design by the hybrid of genetic algorithm and particle-swarm optimisation (F-HGAPSO) is employed for a thyristor-controlled series capacitor (TCSC) to improve the transient stability of flexible AC transmission systems (FACTS). According to the variation of rotation speed, a fuzzy controller decides an approximate series capacitance to achieve a better dynamic response of FAC...

Congestion Management (CM) is a very important aspect of present deregulatory power environment. In the restructured power market congestion occurs when the transmission network is unable to accommodate all the desired transaction due to violation of system operating limit. Increase of real power loss, increase of load demand compared to generated power, lack of Var sources or the fall of volta...

A new modified severity function is proposed, based on which the N-2 line contingencies in the IEEE 30 bus system are analyzed and ranked. FACTS devices like Static VAR Compensator (SVC) and Thyristor Controlled Series Capacitor (TCSC) are used for achieving reduction in under voltage severity value and reduction in voltage deviation from the nominal value. A hybrid combination of two heuristic...
