Features and Improvements
- Auxiliary Files (SCRIPT and DATA Sections): Added special processing for ISO-New England for reading an entire case as an AUX file (called by choosing File\Option Case or when using the OpenCase script command). Previously, special processing was occurring whenever any AUX file Branch DATA section was read, but this was removed in the May 10, 2021 patch because the old behavior was causing bugs in some new ISO-NE processes. Dating back to 2006, ISO-NE had expected the PowerWorld would automatically populate the BranchDeviceType field when reading an AUX file that has Branch objects with CustomString, CustomString:1, or CustomString:2 fields with entries of "line", "zbr", "breaker" etc. The patch for today has brought back that behavior but ONLY when loading an entire case as an AUX file and when the BranchDeviceType field for a particular branch was not populated anywhere else in the AUX file. This new patch brings back the old behavior desired by ISO-NE, but prevents the problem with general AUX files found in May 2021.
- Available Transfer Capability (ATC) Tool: Script commands have been added to access these features: InterfaceRemoveDuplicates; and InjectionGroupRemoveDuplicates. (See Case Information Display patch update below for an explanation)
- Case Information Displays: When working with data that has been collected from multiple organizations, it is possible to have duplicate interface and injection group definitions that have the same elements but different names. Previously this was difficult to detect. We have added a feature to detect and remove duplicate injection groups and interface definitions. This is implemented with the 'Remove Duplicates' button which can be found in the local (right-click) menu for both objects. The 'Remove Duplicates' feature applies to all injection groups or interfaces. Any duplicate definitions are deleted from the model. For comparison purposes, an injection group participation point is considered to be the same if it is for the same object, has the same AutoCalc value, initial value, and participation factor. An interface element is considered to be the same if it references the same object with the same monitored and weighting. The order of the participation points or interface elements does not matter for the duplicates check.
- Oneline Diagrams: Added two new discrete 21 color maps that are suppose to work well in color blind situations.
Added a 34 color discrete contour that is similar to what is used by ERCOT for their LMP map. - Oneline Diagrams: Added an object list for KML File Imports objects. Also now can read lines and points that are not in PowerWorld Format. Points will be drawn as an ellipse.
- File Formats: Fixed a bug that could under very rare circumstances cause Simulator to hang or fail when opening older supported text file formats. This was not a problem with AUX files.
