Bug Fixes

  • Contingency Analysis: For linear contingency analysis, dc contingency analysis, or ATC analysis, lines whose terminal buses become disconnected during a contingency should not be included as valid monitored lines. This has been fixed. For interfaces, any lines in the interface that become disconnected because their terminal buses are disconnected will now be excluded when determining the post-contingency flow and OTDF for an interface.
  • PV and QV Curve (PVQV) Tool: When running QV analysis on a full topology case, errors and access violations could occur if a contingency or base case did not solve and fake generators were used to try to make them solvable. An access violation could also occur if clicking the Stop button to abort a run. All of these problems have been fixed.
