Bug Fixes

  • Auxiliary Files (SCRIPT and DATA Sections): There was a bug in the data check tool where the summary information on the owners table was incorrect. This was being caused by the improper inclusion of generators only used for internal modeling at an SVC bus. This has been fixed.
  • Available Transfer Capability (ATC) Tool: When using the Full CTG Solution method with ATC and iterating on failed contingencies, it was possible to get into an infinite loop when the transfer level reached the minimun stepsize. This has been fixed.
  • Case Information Displays: Showing any DataGrid objects in a User Defined Case Information Display was not working. This has been fixed.
  • Sensitivity Calculations: Fixed "zero determinant in back substitution in row xxx" errors that can occur in a case that has SVCs when doing sensitivity calculations.
