The modern power system is operating closed to its voltage and thermal instability limits. The present transmission network was not originally planned for heavy power trading in the market. The time is to maximize the utilization of existing transmission lines and to manage the congestion. FACTS (Flexible AC transmission system) devices are having capability of improving power transmission, improving voltage profile, minimizing power losses, etc. This paper presents a review on how FACTS devices are used to provide the maximum relief to the congested line by computation techniques. The proposed paper uses sensitivity index to locate FACTS devices optimally. These computation techniques are used solve the OPF (Optimal Power Flow) problems on various IEEE buses.
