Features and Improvements
- Transient Stability: Added error check on Vac_ref in CHVDC2. If the initial AC voltage at either the rectifier or inverter is less than this value, then the value of Vac_ref is modified at initialization. This model doesn't make any sense if the initial voltage is below Vac_ref.
- Transient Stability: Fixed a bug introduced in the August 28, 2017 patch that made creating a plot in transient stability fail.
- Transient Stability: Made a correction on the direclen line relay model
