Abstract
A framework for accurate determination of Available Transfer Capability (ATC) of interconnected power systems with respect to a set of proposed power transactions is presented. A full AC nonlinear modeling of power systems including the effects of control devices is employed in the framework. Both static and dynamic security constraints under a list of credible contingencies are taken into account in the framework. A computer package implementing this framework for ATC evaluation of large-scale power systems is developed. One distinguished feature of this tool is that it provides a list of the topmost severe contingencies in terms of ATC and identifies the associated violated constraints. This feature offers a platform for the development of effective migration schemes to increase ATC. This tool was applied to compute the ATC satisfying the static security constraints of a 15,000-bus system with promising results.
