Synthetic Texas Case (ACTIVSg2000)

Case Description

This case is adapted from the ACTIVSg2000 synthetic Texas grid from the Texas A&M Electric Grid Test Case Repository: https://electricgrids.engr.tamu.edu/electric-grid-test-cases/

It is configured with GridKit-compatible dynamic models.

Data Notes

  • Generator 6215_1 in source data had Xl == Xdpp == Xqpp = 0.2011, which can trigger division-by-zero during GENROU initialization.

  • In this case, Xl was reduced to 0.1911 to satisfy Xl < Xdpp.

Events

The following event types are provided for this case.

  • Bus fault

Dynamics

Have not been implemented in GridKit:

  • ESAC1A

  • ESDC1A

  • ESST4B

  • EXAC2

  • EXPIC1

  • SCRX

  • GGOV1

  • HYGOV

  • IEEEG1

  • GENSAL (In GridKit, not added to this case yet)

  • IEEEST (In GridKit, not added to this case yet)

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 \(\neq 1\))
