Interactive evaluation of ATC using a graphical user interface

This paper presents an interactive ATC calculation program, which is developed primarily as an educational tool. The program runs under the graphical user interface of a previously developed software package, power system educational toolbox (PET) (P. Krizan, et al., 1998). The user can choose multiple sources and sinks as sellers and buyers for a power transaction. Repeated power flow solutions are obtained and results displayed as the user incrementally varies the transaction amount interactively. Utilization of the program is illustrated using example cases.
