Gelli, I am afraid that the question you are asking might be rather trivial. You can model the entire system and specify individual areas (refer to Matpower User Manual, Appendix Data Format <http://www.pserc.cornell.edu/matpower/manual.pdf>). In Table B1, you will see that the column 7 lets you specify which area you want those particular buses to be in.
I hope this helps. Abhilash (Abhi) Kantamneni A Rather Nice Guy, PhD Student, Department of CS, Engineer, Keweenaw Research Center, Michigan Tech 906 231 4208
