Features and Improvements
- Transient Stability: Signal E_FE for exciter AC7B is now available for plotting in the transient stability plot designer
- Power Flow Solution: When a branch had an impedance below the ZBRThreshold and also had a large phase shift or off-nominal tap ratio, it could result in bad power flow convergence. This has been fixed. It was showing up at bus number 516007 in Eastern Interconnection case.
- Transient Stability: Fixed a bug in the parameters Qdn1, Qdn2, Qup1 and Qup2 to ensure they are treated as in per unit on the Plant MVABase for the REPC_C Model
