Features and Improvements

  • Auxiliary Files (SCRIPT and DATA Sections): When specifying a Source or Sink that cannot be found for a Direction object when loading from an auxiliary file, put error message in the log that the Source or Sink will be set to Slack instead.
  • Case Information Displays: Added TSContingency string grid table to the customizable tables. Now the customization of the Transient Contingency table can be saved.
  • Case Information Displays: Added nine superarea voltage fields showing min/max/avg for pu voltage, voltage angle (degrees) and voltage angle (rad).
  • Case Information Displays: Added ability to specify generator voltage setpoint and setpoint tolerance in kV. Added generator field to show the RegBus Nom kV.
  • Case Information Displays: Added TSContingency string grid table to the customizable tables. Now the customization of the Transient Contingency table can be saved.
  • Case Information Displays: SendToExcel script command will no longer change the workbookname and worksheetname to uppercase.
  • File Formats: Added optional parameters filtername and AppendFile to the CTGWriteFilePTI script command. The filter is applied to the Contingency object type to specify the contingencies that should be saved to file. All contingencies are saved by default. Set AppendFile to YES to append to an existing file or NO to overwrite an existing file. File is overwritten by default.
  • File Formats: In various places where contingency files in the PTI CON format are saved in the GUI a prompt will appear if the file already exists asking the user if the file should be overwritten or appended.
  • Oneline Diagrams: Added an InjectionGroup field.
  • Time Step Simulation: Changed time domain simulation so a reset actually resets the time to the start time.
  • Transient Stability: New transient stability fields for UEL/OEL/SCL. UEL/OEL dynamic models now have a transient stability integer field called "Activation Status". SCL dynamic models now have two transient stability integer fields called "UEL Activation Status" and "OEL Activation Status". Possible values are 0 (Idle), 1(Engaged) and 2 (Saturated).
  • User Interface Dialogs: Added ability to show all area supply or demand curves for a super area.

    • Bug Fixes

    • Auxiliary Files (SCRIPT and DATA Sections): Corrected generator variable name RegVoltkVError to RegBuskV (it has always showed the actual kV)
    • Oneline Diagrams: Fixed bug associated with the display of multiple grouped objects, mostly when at least one of the objects is not a text object, like a background rectangle.
    • Oneline Diagrams: Fixed a bug where Snap To Grid was not being returned to its previous value after being temporarily set to True
    • Sensitivity Calculations: When using consolidation with a full topology case, calculations for shift factors and PTDFs may not have been correct when using injection groups containing bus participation points as the source or sink. This has been fixed.
    • User Interface Dialogs: Fixed bug with TGen.MWLambda when fuelcost + extrafuelcost = zero. This would only affect economic dispatch or the code showing a supply curve so the bug would not be common.
    • User Interface Dialogs: Modified generator, area and superarea charts to handle negative marginal costs; also provide access to options so curves can be customized, though right now the change are not stored.
