Case Description

This case is a modified version of the NE 39-bus case, available at the Texas A&M University Electric Grid Test Case Repository. It has been modified to include GridKit-compatible generator models.

Events

The following event types are provided for this case.

  • Bus fault

Outstanding

Dynamics

Only one exciter model is outstanding:

  • EXST1_GE

The following examples needs to be constructed with this case. Currently the only events that have been implemented are faults. This is a practical case to use for modeling outages, or even forced oscillations.

  • Line Outage

  • Generator Outage

  • Forced Oscillations

Statics

GridKit models Switched Shunts as Load with constant impedance,but this erases information and our ability to statically re-initialze the model if initalizing at a different operating point.

  • Transformers (LTC and Tap Ratios \(\neq 1\))
