Abstract: In the Restructuring of power system networks, calculations of Available Transfer Capability (ATC) has become a key issue for power system operators to know the system strength for effective use of transmission network. In this regard, this paper presents the methodology to calculate the ATC values in a standard power system network for base load and modeling of load conditions. To present the ATC values in a more realistic way, the load modeling has been considered for the standard power system network i.e New England 39 Bus System. The results obtained are quite encouraging and useful in the present deregulated environment.
