IEEE 30 bus Test


The IEEE 30 Bus Test Case represents a portion of the American Electric Power System (in the Midwestern US) as of December, 1961.

The 11 kV and 1.0 kV base voltages are my guess.

The model actually has these buses at either 132 or 33 kV.

The 30 bus test case does not have line limits!

The data was downloaded from the IEEE power systems test case archive at [1].
