Abstract : In a deregulated power system structure, power producers and customers share a common transmission network for wheeling power from the point of generation to the point of consumption. All parties in this open access environment may try to produce the energy from the cheaper source for greater profit margin, which may lead to overloading and congestion of certain corridors of the transmission network. This may result in violation of line flow, voltage and stability limits and there by undermine the system security, utilities therefore need to enhance “available transfer capability (ATC)” to ensure the system reliability is maintained while serving a wide range of bilateral and multilateral transactions. This paper focuses on the enhancement ATC using multi FACTS devises i.e combination of Thyristor Controlled Series Capacitor (TCSC) and Thyristor Controlled Phase Angle Regulator (TCPAR). The optimal location of FACTS devices were determined based on Sensitivity methods. The Reduction of Total System Reactive Power Losses Method was used to determine the suitable location of TCSC and TCPAR for ATC enhancement. The effectiveness of proposed method is demonstrated on modified IEEE-9 bus system and 24 bus real time system using power world simulator 8.0
