The IEEE 14 Bus Test Case represents a portion of the American Electric Power System (in the Midwestern US) as of February, 1962.

The 14 bus test case does NOT have line limits. Compared to 1990's power systems, it has low base voltages and an overabundance of voltage control capability.

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

More details of the dynamic data used on IEEE 14-bus test system can be found on the following link
