Features and Improvements

  • Case Information Displays: On the Case Description page added support for an Assumed Date for Determining Inservice Devices. Currently this date is only used for determining whether generators are retired, future, or current. This date needs to be different from the case date since the case date is modified by the time step simulation. By default this date is the same as the case date.
  • User Interface Dialogs: Enhanced the File Browser to return all file dates: created and last modified
  • Bug Fixes

    • Available Transfer Capability (ATC) Tool: When attempting to ramp an ATC transfer with a negative step and the full step amount could not be achieved, the process could stop prematurely without attempting the full step in smaller steps due to a tolerance bug. This has been fixed.
    • Case Information Displays: Generally fixed issues with displaying and switching between filters when filtering display objects. Filters for display objects will now show up in the list of filters in both the Model Explorer and Display Explorer. This will allow them to be saved to and loaded from auxiliary files. All filters will be saved to PWB files, but only filters that are used with dynamic formatting, contours, geographic data view styles, and select by criteria sets will be saved to PWD files or AXD files of complete onelines.
    • Contingency Analysis: When auto inserting contingencies by bus grouping, groups with only 1 bus were not being named using the grouping convention to name based on the outside buses of the boundary lines. This has been fixed so these contingencies are named consistently.
    • Scheduled Actions: Fixed a bug in Open Breakers actions where already-isolated elements were misidentified as unable to be isolated
      Fixed the Current Status and InOutage fields to properly reflect the current state of Scheduled Action application
    • Time Step Simulation: Fixed a few bugs with loading aux files into the Time Step Simulation form, and on the Modal Analysis Frequency dialog added the ability to scale the mode values on the transfer.
