| Abstract: | In a deregulated power system structure, power producers and customers share a common transmission network for wheeling power from the point of generation to the point of consumption. All parties in this open access environment may try to produce the energy from the cheaper source for greater profit margin, which may lead to overloading and congestion of certain corridors of the transmission network. This may result in violation of line flow, voltage and stability limits. In power system environment voltage stability plays major role, it is integral part of the power system stability. In general Voltage stability problems occur more frequently in a heavily loaded system. Lack of voltage stability may develop severe problems in the power system, which might lead to system black out in the form of sudden voltage dips at the load buses. The cause of voltage instability could be numerous. The control of voltage levels can be accomplished using FACTS Controllers like Static Var Compensator (SVC), Thyristor-controlled series capacitor (TCSC). This paper focuses on the enhancement Voltage Stability using FACTS devices. The optimal location of FACTS devices were determined based on Sensitivity methods. The effectiveness of proposed method is demonstrated on modified IEEE-9 bus system using power world simulator 8.0.
