IEEE 118 bus Test
The IEEE 118 Bus Test Case represents a portion of the American Electric Power System (in the Midwestern US) as of December, 1962.
This IEEE 118 bus system contains 19 generators, 35 synchronous condensers, 177 lines, 9 transformers and 91 loads.
The data was downloaded from the IEEE power systems test case archive at .
The diagram can be consulted at  and the data for the rate lines can be seen at  and finally the data for generators have been taken from .
