Secure and reliable operation of the power system is a critical issue for large, complicated, and interconnected power system networks. Security constraints such as thermal limits of transmission lines and bus voltage limits must be satisfied under any operating point in order to deliver reliable power to the consumers. One of the best alternative solutions of improvement of the security of power system is the use of flexible AC transmission systems (FACTS) devices. FACTS devices can be used to limit the power flow on the overloaded line and to increase the use of alternative paths to improve power transmission capacity. This chapter briefly describes all three categories of FACTS devices, namely shunt controllers (static synchronous compensator, static var compensator, thyristor-controlled reactor, thyristor switched reactor, thyristor switched capacitor), series controllers (static synchronous series compensator, thyristor controlled series capacitor, thyristor-controlled series reactor), and combined series-shunt controllers (unified power flow controller).

Intisari — Makalah ini membahas penggunaan peralatan FACTS (Flexible AC Transmission Systems) untuk meningkatkan atau memperbaiki kestabilan sistem tenaga listrik yang terinterkoneksi. Peralatan FACTS pada umumnya digunakan untuk mengendalikan aliran daya-aktif dan/atau daya-reaktif serta untuk mengontrol besarnya tegangan sistem. Namun demikian, dengan memasang alat kontrol tambahan, peralatan FACTS dapat digunakan untuk meningkatkan redaman elektromekanik dan kestabilan sistem tenaga listrik sebagai fungsi sekundernya. Salah satu peralatan FACTS yang cukup populer saat ini adalah UPFC (Unified Power Flow Controller). UPFC merupakan peralatan FACTS generasi ketiga. Peralatan ini menggabungkan kompensator shunt dan kapasitor seri statik menjadi satu peralatan dengan sistem kendali terpadu. UPFC memiliki kemampuan unik untuk mengendalikan aliran daya listrik dan tegangan secara simultan sehingga memiliki potensi untuk digunakan dalam meningkatkan redaman dan kestabilan sistem. Makalah ini menyelidiki aplikasi dari UPFC pada peningkatan kestabilan sistem tenaga listrik yang terinterkoneksi. Keefektifan dari peralatan tersebut dalam memperbaiki penampilan dinamik dan meningkatkan kestabilan suatu sistem tenaga telah dikonfirmasi melalui hasil-hasil perhitungan nilaieigen dan divalidasi dengan menggunakan simulasi domain-waktu.Kata kunci — FACTS, UPFC, Redaman, Kestabilan, Sistem Tenaga Listrik Abstract — This paper discusses an application of FACTS (Flexible AC Transmission Systems) device in improving the stability of interconnected electric power system. FACTS devices are used primarily for controlling active- and/or reactive-power and also for voltage regulation. However, by employing some supplementary controllers, it can also be used for enhancing system electromechanical damping and stability as its secondary function. One of the most popular FACTS devices is UPFC (Unified Power Flow Controller). UPFC is a third generation of FACTS device. This device combines the shunt compensator and static series capacitor as one device with a unified control system. UPFC has a unique ability in controlling simultaneously system power flow and voltage, and therefore, has a potential to be used for system damping and stability improvement. This paper investigates an application of UPFC in improving the stability of interconnected power system. The effectiveness of the device in enhancing system dynamic performance and stability has been confirmed through eigenvalue calculations and validated using time-domain simulations.Keywords— FACTS, UPFC, Damping, Stability, Electric Power System

Purpose The loading and power variations in the power system, especially for the peak hours have abundant concussion on the loading patterns of the open access transmission system. During such unconditional state of loading the transmission line parameters and the line voltages show a substandard profile, which depicts exaction of congestion management of the power line in such events. The purpose of this paper is to present an uncomplicated and economical model for congestion management using flexible AC transmission system (FACTS) devices. Design/methodology/approach The approach desires a two-step procedure, first by optimal placement of thyristor controlled series capacitor (TCSC) and static VAR compensator (SVC) as FACTS devices in the network; second tuning the control parameters to their optimized values. The optimal location and tuning of TCSC and SVC represents a hectic optimization problem, due to its multi-objective and constrained nature. Hence, a reassuring heuristic optimization algorithm inspired by behavior of cat and firefly is employed to find the optimal placement and tuning of TCSC and SVC. Findings The effectiveness of the proposed model is tested through simulation on standard IEEE 14-bus system. The proposed approach proves to be better than the earlier existing approaches in the literature. Research limitations/implications With the completed simulation and results, it is proved that the proposed scheme has reduced the congestion in line, thereby increasing the voltage stability along with improved loading capability for the congested lines. Practical implications The usefulness of the proposed scheme is justified with the computed results, giving convenience for implementation to any practical transmission network. Originality/value This paper fulfills an identified need to study exaction of congestion management of the power line.

Abstrak – Sistem kelistrikan merupakan salah satu kebutuhan bagi kehidupan masyarakat modern dalam mendukung keberlangsungan aktifitas masyarakat. Peningkatan beban pada sistem tenaga listrik dapat menimbulkan jatuh tegangan dan nilai rugi daya yang besar. Dalam tugas akhir ini digunakan SVC (Static Var Compensator) yang merupakan salah satu FACTS devices, yang berfungsi menyerap atau menginjeksikan daya reaktif untuk memperbaiki profil tegangan pada sistem transmisi. Tugas akhir ini adalah studi kasus yang diterapkan pada saluran transmisi PLN 24 bus wilayah Lampung dengan menggunakan metode Newton-Raphson pada simulasi MATLAB.  Hasil penelitian menunjukkan bahwa dengan menerapkan SVC pada weak bus pada sistem transmisi maka profil tegangan dapat diperbaiki dalam batas yang diizinkan. Penempatan SVC pada weak bus 7 (Manggala) memperbaiki profil tegangan pada weak bus 7 (Manggala) dan bus 8 (Gumawang) naik sebesar 1.35% dan 1.45% dari 0.9283p.u dan 0.9012p.u menjadi 0.941p.u dan 0.9145p.u, penempatan SVC pada weak bus bus 8 (Gumawang) memperbaiki profil tegangan pada weak bus 7 (Manggala) dan bus 8 (Gumawang) naik sebesar 6.18% dan 9,88% dari 0.9283p.u dan 0.9012p.u menjadi 0.9895p.u dan 1p.u.
