This presents an algorithm for the enhancement of voltage stability subjected to operational inequality constraints by rescheduling of reactive power control variables. Amount of Reactive power which is obtained from UPFC to be injected which is determined using minimum eigen sensitivity of load flow Jacobian of the system. System voltage stability has been evaluated using continuation of power flow. Voltage instability is a quite frequent phenomenon under such a situation provide reduction of power system performance. In order to avoid voltage collapse, blackouts, power system is to be analyzed in view of voltage stability for a wide range of system operating condition. Developed algorithm has been implemented on IEEE 14-bus system.
