Khajehzadeh M., A survey on flexible AC transmission systems

Abstract. The flexible alternating current transmission system (FACTS), a new technology based on power electronics, proposes an opportunity to improve controllability, stability, and power transfer capability of AC transmission systems. This article presents a comprehensive review and evaluation of FACTS controllers. This paper provides an extensive analysis on the research and improvements in the power system stability development using FACTS controllers. Several technical publications related to FACTS installations have been highlighted and performance comparison of different FACTS controllers has been discussed. Moreover, some of the utility experience, real-world installations, and semiconductor technology development have been outlined. Streszczenie.
