9-Bus system with Synchronous Generators and control

I created this as a part of my own education of how to build a model for analyzing transients

This file has 9-bus system with three synchronous generators. I used "Improve Transient Stability Using SVC and PSS" example as a reference for the generator control (HTG) and one thing that perplexed me is the need for me to add a nominal power block to the generator outputs where as the example didn't needed any. Of course, I am using "Pi" sections and "discrete" simulation but that doesn't explain me much. If you find it useful, feel free to use it. I am not even sure if this captures dynamics in any useful way. But your comments and suggestions might help me do a useful job
