The main issues in the current power system network are about load side voltage stability and reactive power sustainability throughout the running time. Both the issues can be upheld by using different shunt and series FACTS devices. There is always a probability of losing stability in the power system because of various disturbances occurring continuously. In this paper, placements of SVC, STATCOM, SSSC and UPFC for the total reactive power loss and voltage stability enhancement have been identified for IEEE 9-BUS as a case study in PSAT/MATLAB software. Relative analysis depending on the distinct location of SVC, STATCOM, SSSC and UPFC is made, it is seen that by placing the FACTS devices at a suitable position, the voltage profile of the buses gets improved. The stability study has been conducted for SVC, STATCOM, SSSC, and UPFC with the help of PSAT/MATLAB whereby it reflects that for UPFC there is maximum voltage stability and minimum total reactive power loss of the system.
