Unified power flow controller (UPFC) is a powerful device which can control three power system parameters and it must be located optimally to obtain satisfactory performance due to excessive cost. This paper presents an approach to find the optimal placement of UPFC based on the line stability index. The line stability index can provide accurate information of the stability condition of the lines of the system and can also determine the weakest bus in the system. The index is evaluated for partial network of Myanmar National grid transmission network using MATPOWER Toolbox and a line having largest value of the index is the most critical line where the optimal location of UPFC. The proposed placement approach is shown to be effective for finding appropriate location of UPFC and the effects of UPFC allocation based on line stability index are also demonstrated using Power System Analysis Toolbox (PSAT). The optimal placement of UPFC based on the line stability index resulted in enhancing the power flow control of the system, reducing the system losses as well as improving the system voltage profile.
