Events

The following event types are provided for this case.

  • Bus fault

Outstanding

Dynamics

Only one exciter model is outstanding:

  • REECB1

  • GAST_PTI

  • REGCA

  • REPCA1

The following examples needs to be constructed with this case.

  • Line Outage

  • Generator Outage

  • Forced Oscillations

Statics

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

  • Switched Shunts

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