The aim of the paper is to enhance the power system stability and to reduce the power losses in three area interconnected power system [10] using TCSC and SVC. In present power system, controllability of power losses is a major issue, and also enhancement of system stability is an important task to improve power system .For that purpose we are analyzing 47 bus system i.e. interconnection of three areas, such as 9 bus , 14 bus and 24 bus. The comparison between general 47 bus system is detailed

The best location of the FACTS device is recognized by Power Flow Analysis .The analysis is carried out using power system Analysis Toolbox (PSAT) software.In this paper we are going to find the best location of installing facts devices in 47 bus system. We are analyzing the system behavior and minimization of real power losses in the 47-bus system and advance technology of facts device enhances stability. we are using TCSC and SVC within the system and identify the best location where the real power losses are reduced compared with 47-bus system without facts devices, and we are placing HVDC links to interconnect the three areas such as 9-bus, 14-bus & 24-bus to form 47-bus system .While comparing individual TCSC device, SVC device, HVDC link and every possible combination (TCSC, SVC & HVDC), the real power losses are minimized (less) in combination when compare to individual cases. Combination of both devices gives better performance for 47 bus system. The simulation has been carried out in PSAT [9] interfaced with MATLAB package.
