The evaluation of available transfer capability (ATC) is going importance in the restructuring of power sectors due to the increased interchange among utilities. Computing the ATC is a complicated optimization problem. State of the art techniques such as contingency selection and optimal power flow (OPF) should be integrated in order to implement the computation. This paper concentrates on the latter and shows a procedure for determining the interchange capability during the base case condition using an OPF. The OPF is specifically formulated for ATC assessment purpose and aimed at real time applications. A deterministic case is examined here.
