Features and Improvements

  • Auxiliary Files (SCRIPT and DATA Sections):
  • GIC: Modified the script command GICLoad3DEfield to include an option to setup the Time-VaryingSeries on Load. The script now looks like this:
    GICLoad3DEfield(FileType, CoarseFile, SetupTVSOnLoad); SetupTVSOnLoad is not optional and is a YES/NO option and default is false.
  • User Interface Dialogs: Modified the Refresh Displays button the Window Ribbon tab to have a small icon of a grid. This makes adding the button to the Quick Access Toolbar look nicer.
  • Bug Fixes

    • Available Transfer Capability (ATC) Tool: Added new comment in the ATC tool. If you choose an Area, Super Area or Zone as the buyer or seller, but that area doesn't have any generation, you will get an error saying "Seller 'the Seller Type' does not have any generation for direction 'direction name'" or "Buyer 'the Buyer Type' does not have any generation for direction 'direction name'". Right now though, it says "Seller and buyer are not in the same electrical island for direction Slack to AREANAME (AREANUM)"
    • Contingency Analysis: Prior to running any contingency analysis or combo contingency analysis related functionality any islands created because of the option to "dynamically add/remove slack buses as topology is changed" will become permanent islands. This is to prevent the islands from being removed if a full contingency solution is done and the "dynamically add/remove..." option is not used. It is assumed that the topology that exists prior to any contingency analysis is the desired topology.
    • Contingency Analysis: Fixed access violations that could occur when deleting CTGComboViolations that are island violations.
    • PV and QV Curve (PVQV) Tool: Prior to running PV or QV analysis any islands created because of the option to "dynamically add/remove slack buses as topology is changed" will become permanent islands. This is to prevent the islands from being removed if the "dynamically add/remove..." option is not used with different sets of options. It is assumed that the topology that exists prior to any PV or QV analysis is the desired topology.
    • PV and QV Curve (PVQV) Tool: It was possible that when loading PV or QV results from an aux file that the results would not be loaded correctly for the Base Case scenario if there also happened to be a contingency named "Base Case". Now always assume that the results are for the base case scenario with no contingency and that there should not be a contingency named "Base Case".
