  • Transient Stability: Modified the REGC_C model to have non-windup limits for +Imax/-Imax on the PI controller for currents
  • Bug Fixes

    • Contingency Analysis: Various options are available on case information displays showing contingencies to insert, modify, and delete contingencies. Contingency case information displays are available on multiple dialogs like Contingency Analysis, Model Explorer, ATC, etc. Not all of the case information displays would be updated with new information depending on where the action was initiated. This has been fixed.
    • Transient Stability: Added an initial limit violation for message for discrete shunts in transient stability
