Tóm tắt

This paper presents a user-friendly software in modeling daily base case by including the peak power interchange, forecast loads, scheduled generator, and transmission line outages. In order to model an interconnected power system accurately, the items mentioned above must be included into the base case before running the contingency screening. This software will abstract all downloaded files from the NERC web site and process them according to the requested query hour. Finally, the software will create an user defined input batch file (idv file) that will after the base case's power interchange, loads, and scheduled generator and transmission line outages in PSS/E power load flow program. In fact, two versions of this software have been developed with a full power interchange model and a decoupled power interchange model. The decoupled power interchange model is only concentrating on the southern security coordinators' power interchange to the north. The full power interchange model is including all the transactions in that peak hour.
