Bug Fixes

  • General: When tapping a transmission line and choosing the option to "Use Line Shunts", if existing line shunts were on the transmission line, then the shunt values were not set correctly. This has been fixed.
  • Oneline Diagrams: The patch on March 4 caused Zone fields that show MW or Mvar flow to another zone to always show as blanks. This has been fixed.
  • Power Flow Solution: If there are multiple generators at the system slack bus and not all have AGC = YES, it was possible that the slack generators could end up with very different MW dispatches with one or more with negative MW outputs. This could occur when using Island-Based Dispatch with all generators on AGC with non-zero participation factors participating and all generators hitting MW limits. This has been fixed.
