Features and Improvements
- Oneline Diagrams: On the dialog for Auto-Insert Buses on a oneline, added a new check box option to "Only Insert Buses that are a FixedNumBus".
- Optimal Power Flow (OPF): The OPF option "Distribute Change Among Equal Cost Generators" (added on June 25, 2025) is now renamed more aptly as "Balance Marginally Similar Controls". This option is useful in balancing control variables that have similar sensitivity vectors in the OPF or SCOPF tableau, and providing a dispatch where groups of controls (based on similar sensitivity) will participate in a manner that puts them in the same relative point within their linear cost segments. Without enabling this option, the behavior would be the as it was prior to June 25, which would incrementally assign control changes to one control at a time, until the desired impact is achieved by simplex linear program. The initial June 25 update provided a way to balance only Generator MW controls, and only under certain type of constraints. This present update handles all types of controls and all types of constraints that are present in the simplex tableau.
- Available Transfer Capability (ATC) Tool: The Reverse Buyer/Seller button on the ATC Dialog did not function properly if the existing Buyer and Seller were not the same type (for example both areas or both zones). This has been fixed so the types also are reversed.
- Case Information Displays: On the Contour Column dialog that Calculate Values button has been giving an error. It is now fixed.
