Abstract: Transfer capability is a key aspect to be taken care by both the power system operators and consumers. Since the load on the power system network increases day by day, the effective utilization of power transmission network is a major criterion to be concentrated in power system network operations. In this paper there are two aspects considered to understand the security of network. Initially the performance of the network is analyzed under contingency condition and later the system performance is also analyzed with the usage of the series FACTS device i.e. TCSC. The methodology is tested in IEEE-30 bus test system.
Keywords: ATC; Bi-lateral Transaction; ACPTDF; contingency analysis; Power Injection model of TCSC.
