Features and Improvements

  • Case Information Displays: Added new case information display option regarding whether to "Show prompt about saving SUBDATA to AUX". This impacts the Generator and Load case information display which previously had prompted the user regarding whether to store the ReactiveCapability or BidCurve information as a SUBDATA section of each object. The user will now be able to choose "Never" and this dialog will no longer appear, though it can be added back by changing the new Simulator Option to show these again.
  • User Interface Dialogs: On dialog/window system menus found by left clicking on the PowerWorld logo in the caption of a dialog, there are now options for "Export" and "Copy to Clipboard" that export or copy images of the dialog.
  • Bug Fixes

    • Auxiliary Files (SCRIPT and DATA Sections): Fixed bug that would not allow the LoadAXD script command to load an AXD file into a oneline that doesn't already exist.
    • Case Information Displays: When listing the Areas, either by Name or Number, that are assigned to a Zone, include gens, loads, and shunts along with buses. Previously only buses were being included.
    • Case Information Displays: When listing the Zones, either by Name or Number, that are assigned to an Area, include gens, loads, and shunts along with buses. Previously only buses were being included.
    • Case Information Displays: Added Case Info Customizations for the following contingency related case information displays: Generator Post-Contingency AGC, Bus Load Throw Over, Generator Maximum MW Response, Generator Line Drop and RCC, and Switched Shunt Post CTG.
    • General: Closing a case containing many injection groups that include other injection groups could be very slow. This has been fixed.
    • Power Flow Solution: Fixed log messages regarding the AGC changing generator MW outputs. They should have been listing the area that was resulting in the change in MW.
    • PV and QV Curve (PVQV) Tool: Removed extra dialog that pops up briefly before opening the PV dialog.
    • Transient Stability: When transferring the Transient Stability operating point to view inside the case information displays in Simulator, errors were appearing related to setting generator voltage setpoints that should not have been appearing. This has been fixed.
    • User Interface Dialogs: The plotting of a reactive capability curve from user-specified points was not working properly. This has been fixed and diamonds have been added to the display to show the points.
    • User Interface Dialogs: On the bus dialog while in Run mode the Selected checkbox and other options on the Custom tab were not being updated to reflect the values associated with the current bus when the dialog was opened unless the Simulator license key included the OPF add-on. This has been fixed. The values set on the dialog were being transferred to the bus when the dialog was closed with the OK button or Save was clicked.
