Features and Improvements

  • Transient Stability: Added more validation checks to ensure that only appropriate groupings of wind models are used such as GEWTG/EWTGFC/WNDTGE, GEWTG/EXWTGE/WNDTGE, and GENWRI/EXWTG1/WNDTRB. This help prevent input errors such as using the full converter electrical model (EWTGFC) with a machine model configured as a DFAG (fcflg = 0).
  • Bug Fixes

    • Available Transfer Capability (ATC) Tool: When using the (IL) the Full CTG Solution method AND while using multiple ATC Scenarios, a bug was was introduced by recent speed enhancements. This has been fixed.
    • PV and QV Curve (PVQV) Tool: When tracking a Voltage to Q injection, Voltage to Power Transfer, or PTDF sensitivities in the PV Curve tool it was possible that the calculations were being performed on an invalid Jacobian matrix resulting in incorrect tracking results. This has been fixed.
    • Transient Stability: Fixed some GUI interaction issues with the transient stability dialog related to the Manual Control the the run.
