Bug Fixes

  • Available Transfer Capability (ATC) Tool: When attempting to ramp an ATC transfer with a negative step and the full step amount could not be achieved, the process could stop prematurely without attempting the full step in smaller steps due to a tolerance bug. This has been fixed.
  • Contingency Analysis: When auto inserting contingencies by bus grouping, groups with only 1 bus were not being named using the grouping convention to name based on the outside buses of the boundary lines. This has been fixed so these contingencies are named consistently.
  • Contingency Analysis: Changed how contingencies are named when automatically inserting contingencies based on bus groupings. It was possible for contingencies to have the same name if basing the name purely on the buses that are on the outside of the grouping. This would cause contingencies to be overwritten and not all expected contingencies were created. Now if a contingency is found with the same name and the contingency actions are different, the lowest bus number internal bus will be appended to the name of the contingency to make the name unique.
  • Contingency Analysis: Fixed bug when saving or loading CTG_AutoInsert_Options to or from an aux file when using the BUSGROUPING element type.
