Geographic location tool for electric power systems

A method for associating geolocation information with a plurality of buses of a modeled power system, wherein the buses are distributed over a geographic area, and each bus of the plurality is electrically connected through respective branches to one or more other buses of the plurality, the method comprising:

• reading a system input file containing architectural information for the modeled power system for a plurality of buses, the architecture information including, for the plurality of buses:
• bus information including one or more of bus number, name, and voltage level, and
• branch information including one or more of from-and-to bus numbers, branch impedance, and length;
• creating a table of impedance and voltage information from branch information that includes branch impedance and length information;
• calculating from the table the length values for each branch that includes branch impedance information but not length information;
• reading a geographic information file that includes numbers or names and corresponding geolocations for a subset of the plurality of buses;
• matching buses from the plurality associated with the architecture information with the buses from the subset associated with the geographic information based on corresponding bus numbers or names;
• determining geolocations for the unmatched buses of the plurality by calculating, for each unmatched bus, its respective geolocation based on lengths of branches between the unmatched bus and two or more matched buses;
• and
• reiteratively repeating the step of determining geolocations with the buses and calculated geolocations from prior iterations being matched buses for subsequent iterations.
