Abstract: With the restructuring of power market, the voltage stability has become a major concern .FACTS devices adaptive to voltage-magnitude controlas well as can regulate the active and reactive power simultaneously because of their flexibility and fast control characteristics. This paper focused on the mathematical modeling of Flexible Alternating Current Transmission Systems (FACTS) -devices in optimal power flow analysis. A Thyristor Controlled Series Capacitors (TCSC) mathematical models have been established, and the Optimal Power Flow (OPF) with these FACTS-devices is solved by Newtons method. This article employs MATLAB Simulation, the development of OPF and the suitability of Newton-based algorithms for solving OPF-TCSC problem is done. The concept was tested and validated with TCSC in 5-bus,14-bus and 30-bus test system. Optimal Power Flow problem has been explored and tested with and without compensating device. The results show that in large-scale system, where the number of constraints is very large, the Thyristor-Controlled Series Capacitor is effective for controlling the specified amount of active and reactive power in between two buses as well improves voltage profile which improves system security . Placement of these devices in suitable location can lead to control in line flow and maintain bus voltages indesired level.
