In this paper steady-state modeling of Thyristor Controlled Series Compensator (TCSC) for power flow studies has been represented and discussed in details. In same manner firing angle model for TCSC is used to control active power flow of the line to which TCSC is installed. The proposed models take firing angle as state variable in power flow formulation. To validate the effectiveness of the proposed models Newton-Raphson method algorithm was developed to solve power flow equations in presence of TCSC. Case studies are carried out on 68-bus (western Algeria) system to demonstrate the performance of the proposed models.
