- Case Information Displays: On the Bus Case Information Display, the "Bus Neighbor List (in service only)" field was reporting all neighbors regardless of branch status. This has been fixed.
- Contingency Analysis: When calculating a multi-section line contingency using the linear methods, the results would not properly account for islanded generation or load if the dummy buses contained generation or load. This has been fixed.
- Power Flow Solution: As part of Robust Solution Process, turn on SVC control if it was originally on.
- Transient Stability: Modified so that in order for an electrical island to be considered viable it must have at least one machine model which is modeled as a voltage source behind an impedance (such as a synchronous machine). Therefore, islands which are created during a simulation by a switching action that result in an electrical island that contains only Type 3 and 4 wind turbines (and other machines modeled as a constant current injection) are not considered by themselves to be enough to support an island.
