Venkata Marutheswar Journal on Electrical Engineering 2230 – 7176 5 1 49 55 Flexible AC Transmission Systems (FACTS), Unified Power Flow Controller (UPFC), UPFC Location, Loss Sensitivity Indices(LSI), Congestion Management In modern power systems controlling of power is flexible and easy by the use of Power Electronics devices. The recent advent of power electronics devices are FACTS Devices. These FACTS devices are playing a major role in the electrical industry. This paper presents the development of simple and efficient model for the suitable location of Unified Power Flow Controller (UPFC). The UPFC location is found by using the congestion management technique. In this paper the location is found based on the Total Loss Sensitivity Indices (LSI). The effectiveness of the proposed method is demonstrated on IEEE 5 bus system. July - September 2011 Copyright © 2011 i-manager publications.
