Features and Improvements
- Auxiliary Files (SCRIPT and DATA Sections): Changes to create contingent interfaces in the script command ATCCreateContingentInterfaces now allows filter to be an optional parameter. Also, the script command now allows the creation of interfaces for base case limiters, which will be created as an interface without a contingency
- File Formats: When writing out transformers to an EPC file, if transformer is Fixed we will now always write type = 1. PowerWorld has a separate field indicating if a transformer's control is enabled and if it's disabled we write a negative sign on the type. However in EPC file type=1 means there is no control at all, so writing a -1 is strange it it means the transformer's control is disabled, but it has no control anyway. To avoid confusion, we just write a 1 instead.
- Transient Stability: Added a new result field for transient stability injection groups. The field is Weighted Average Rotor Speed. The formula is the sum of generator speed times Weight divided by sum of Weights. The intention is to set the Weights to be the H (Inertia) of the generators. The Weights/Inertia are set in the Participation Factors of the injection group.
- Transient Stability: Fixing a bug where the "Do Not Combine RAM Results with Hard Drive Results" setting was interfering with plot generation in Distributed TS runs.
