Features and Improvements

  • Auxiliary Files (SCRIPT and DATA Sections): Added new script command "AutoInsertTieLineTransactions" which takes now parameters. This deletes all existing MW transactions and set the unspecified MW interchange for each area to zero. It then automatically creates a MW transaction between each pair of connected areas with a MW transaction exactly equal to the sum of the tie-line flows.
  • File Formats: Modified the writing of GE EPC file so that Multi-Terminal DC converters will write out the "aloss" parameter in a manner consistent with how the EPCL file mtTAP.p expects to ensure the EPCL operates appropriate for WECC data files.
  • File Formats: On the Present Topological Differences from Base Case dialog, the various case information displays of removed elements have been modified to provide a mechanism to right-click on a selection and choose to Save Selected to EPC file.
  • User Interface Dialogs: On the Present Topological Differences from Base Case dialog, the various case information displays of removed elements have been modified to provide a mechanism to right-click on a selection and choose to Save Selected to EPC file.
  • Bug Fixes

    • File Formats: When saving any file, Simulator was prompting the user about adding a comment to the file. This will now only be done when saving to the most recent PWB file format.
    • Power Flow Solution: Fixed error caused when a MTDC Converter ended up with a current flow of exactly 0.0 amps. This resulted in a number being equal to 0/0 which resulted in a "NAN" result causing the power flow to fail.
    • User Interface Dialogs: Fixed error in feature to remove additional GE EPC data from the case.
