Features and Improvements

  • File Formats: Modified the feature to "Save Known Fields in HDB Pattern File" so that it now writes 4 files
    c:\FilePath\FileName.txt : list of object/fields for exporting a solved case
    c:\FilePath\FileNameCTG.txt : list of object/fields for exporting contingency definitions
    c:\FilePath\FileNameRAS.txt : list of object/fields for exporting the RAS definitions
    c:\FilePath\FileNameHdbexport.txt : Text file describing how to call the hdbexport command
    The FileNameHdbexport.txt is the new file that was added in this patch.
  • Bug Fixes

    • Available Transfer Capability (ATC) Tool: At end of ATC run, TransferLimiters will be sorted from low to high transfer limit, contingency with any base case limiters coming first, and then limiting element. Previously the limiters were not sorted at the end of the calculations, which could result in the limiters being out of order if using the iterated methods. Limiters were being sorted when loading from an AUX or PWB, and this will make the result order consistent immediately after a run and when loading from file.
    • File Formats: Fixed an access violation saving multi section lines to the EPC format in difference mode. In difference mode, the list of lines in the ms line can be nil and they were still being accessed. This has been fixed.
    • Power Flow Solution: When using the option to "Use Loss Factor For DC Line tielines", it was possible for the metered direction of the metered point of the line to be handled incorrectly and thus mess up the ACE calculation and area interchange. This has been fixed.
    • User Interface Dialogs: Fixed problem with the Set Generator Participation Factors tool and the SetParticipationFactors script command that would not set the correct generators when setting by area or zone.
