Importance of FACTS Devices in Power System

Sarbjeet Kaur | Dr. Surbhi Gupta ^[2]

Abstract: Modern power system networks are not able to cope with the increasing demand of power because the generation and transmission capacities are not increasing proportionally with the demand which leads to many problems such as instability, degrading power quality, threat to security and unreliable operation. Earlier mostly the control of power system is done with mechanical switches but now due to the advancement of technology, these conventional control methods are replaced with the new devices called as flexible AC transmission system which increase power system capability and enhance controllability of power system. In this paper a review is presented about FACTS devices that described how these devices prove a boon for power system, while dealing with problems of reactive power control, improving voltage profile, harmonic reduction and congestion management by allowing the static and dynamic control of power system.
