Abstract:

In current years, growth of load demand rises day by day, but this growth does not ensue the same in equipment’s of power systems and therefore operators have to use supreme available capacity of systems to fulfill load demands. These activities make power systems so unpredictable. One of best ways to develop reliability of systems is using FACTS devices. In this project the voltage sag occurred during overloading condition is observed and it can be mitigated by using two type of FACTS devices such as STATCOM and UPFC. FACTS devices can regulate the reactive and active power control as well as adaptive control of voltage-magnitude instantaneously because of their fast control characteristics and flexibility. Placement of these devices in appropriate location can lead to maintain bus voltages in preferred level and control in line flow and so increase voltage stability margins. Performance assessment is supported by the simulation results on IEEE 6 bus system under overloading conditions using MATLAB.
