Features and Improvements
- Transient Stability: Added new Hybrid Inverter-based renewable Machine model named REGFM_C1. This model is called a "hybrid" model because it acts as simultaneously a Grid Forming Converter and a Grid Following Converter. This model is in beta development in conjunction with the WECC Model Validation Subcommittee.
- Contingency Analysis: When writing out CON files with REMOVE SWSHUNT or ADD SWSHUNT commands, modified to ensure that the ID string is also written after the SWSHUNT command. We added ability to read these commands with or without the ID several months ago, but when writing we were still omitting the ID string.
- File Formats: When writing out MVA limits D..K for transformer windings to a RAW file we were mistakenly writing out limits D over and over. This has been fixed.
- Transient Stability: The feature for showing Stability Models with bold fonts to indicate non-default values was no longer working. This has been restored.
- Transient Stability: Fixed error which could cause the final point of a PlayInGen voltage/frequency value to be ignored.
- Transient Stability: There was a bug in REPC_C model where the dialog and columns were only showing the first 11 Switched Shunt objects being controlled by the REPC_C and were missing the 12th if it existed. Now this was fixed.
