Now a days due to the ever increasing demand of power, the transmission line are to be operated under loaded condition and that’s why there is a risk of power flow control and voltage instability. Voltage stability is an essential factor, which needs to be taken into attention during the planning and operation of electrical power systems in order to avoid voltage collapse and consequently partial or full system blackout. By the analyzing of the voltage stability, system operators need to know not only the severity of the system instability, but also the mechanisms that cause voltage instability in the system. In this paper by application of TCSC and SSSC facts devices in the transmission network, the power flow control as well as voltage stability have been studied. The TCSC and SSSC are a series compensated device to reduce the transmission line reactance in order to improve power flow as well as to improve the voltage profile also. A systematic procedure for modelling and simulation by application of facts devices using MATLAB/SIMULINK have been presented. The optimal location of TCSC and SSSC device are considered for power flow control and voltage stability limit. The proposed approach is carried out on four-area, eight-machine, and 17-bus test system in order to simulate and validate the system. The paper also compiles the results of improvement by the application of the above series compensated facts devices.
