- Power Flow Solution: It is possible for a generator that was not initially on AVR control to get pegged at a Mvar limit and never be allowed to move from the limit if it was set on AVR control. This has been fixed. This fix is related to the fix that was made with the Jan. 25, 2012 patch also related to generators being set at Mvar limits.
- Transient Stability: Fixed failure of network boundary equation solution when a DC line terminal has been de-energized due to line switching on the AC system. Previously, this would result in the transient stability aborting. It will now properly model the outage of the converter.
