Features and Improvements
- Available Transfer Capability (ATC) Tool: Modified internal numerical routines to make them faster.
- Sensitivity Calculations: Modified internal numerical routines to make solutions faster.
- Integrated Topology Processing (ITP): Fixed a potential issue with restoring states when using consolidation related to a generator's regulated bus number.
- Oneline Diagrams: Fixed a oneline "flicker" that could occur when using the line navigation arrows.
- Oneline Diagrams: The 3D oneline options were not available when right-clicking on a oneline diagram in 3D mode. This has been fixed.
- Power Flow Solution: Presently Switched Shunts can not be on continuous control in the inner power flow loop if they are at a bus that is being regulated by generators remotedly. An error check prevents this now.
- Power Flow Solution: Fixed a situation where a phase or tap were not being brought back within the Min/Max Tap (or phase) range when enabling a transformer for control which started outside of its allow range. It will now be properly set to be within range.
- Power Flow Solution: When using the robust solution process, solve the full newton at the end of the process even if the previous solution failed. The previous failed solution may have been from the decoupled power flow and the full newton might converge. Solves a problem encountered with WECC cases.
- Time Step Simulation: Fixed error with creating time step actions which change the generator voltage setpoint.
- Transient Stability: The initialization process for a load which was out-of-service in the power flow case was preventing that load from being closed in during the transient contingency simulation. This has been fixed.
