This paper presents an approach for enhancement of voltage stability of an interconnected power system employing distributed generators (DG) along with conventional generators. When the DG is from wind then voltage instability in the system is of great concern. In this paper a 28 bus test system is considered where the wind penetration varies from 10% to 99% over the day. This causes a large variation at different bus voltages violating the grid code. A shunt FACT device (SVC) is used to mitigate this problem at the buses connected to wind generators. Thereafter, suitable locations for the SVC placement are identified to enhance the voltage stability and reduce system power loss. The simulation study is carried out on the system using the software program developed in Matpower-4. The same is verified by using the software MiPower
