Features and Improvements

  • Contingency Analysis Tool: Added option to auto insert three-winding transformers.
  • Bug Fixes

    • Power Flow Solution: Angle smoothing is done at the start of the power flow solution to condition voltages across branches that have just been closed in. There were some instances when this was producing "zero determinant" errors. This has been fixed. If an error is encountered while trying to do the angle smoothing, this will be noted in the message log and only voltage estimates at buses between the buses specified for smoothing will be calculated.
