Features and Improvements

  • Transient Stability: Added support for the transient model REGCBU1 to be able to read and write out from and to a dyr file. The model translate to REGC_B in PowerWorld.
  • Bug Fixes

    • Auxiliary Files (SCRIPT and DATA Sections): The CloseWithBreakers script command was not working correctly if trying to connect a Bus object using breakers. This has been fixed.
    • Contingency Analysis: When using OPENCBS actions with contingency analysis and no breakers can be found that isolate the element, an OPEN action on the element itself will be applied. This action is created as a dynamic action that should be cleaned up at the end of contingency analysis. This wasn't happening so extra messages might appear in the message log or What Occurred as subsequent contingency runs are done. This won't affect the contingency results. This has been fixed.
