Hanuman P. Agrawal and Hariom Bansal*   Pages 1206 - 1216 ( 11 )


Background: The power industry has been evolving continuously and influenced by a competitive deregulated market. The crucial demand to maximize the efficiency of the existing equipment requires it’s proper management. Flexible AC Transmission System (FACTS) are flexible devices, which provide dynamic control over the power system to cope with its dynamic nature.

Methods: An extensive review is carried out on FACT devices covering its classification, importance, optimal placement and influence on the power systems.

Results: In this paper, different techniques to identify the optimal location of placing FACT devices have been discussed and compared, as the placement of these devices in the power system is of utmost importance for its efficiency.

Conclusion: This paper summarizes techniques available for optimal placement of FACTS devices in order to improve power system performance. It will serve as a ready reference for the future researchers in this field and help them in selecting the proper devices to carry out their work.
