Features and Improvements

  • Difference Case Tool: When showing some values in difference flows we show the Present Value followed by a | character followed by the Base Value such as " 103.45| 206.45". Depending on how wide the column is on the display however the text may have the portion of the string with the | character truncated. If the user can not see the | character it makes is confusing as to whether the value has changed or not. To avoid this confusion, we will now show the background color of cells shown in difference flows that contain a | character with a slightly different background color to indicate the value has changed.
  • Bug Fixes

    • Auxiliary Files (SCRIPT and DATA Sections): Changed the tolerance for the injection group ramping options for Merit Order and Merit Order Close to be consistent with tolerances used during ATC ramping. An infinite loop could result during ramping while using one of these methods and also using one of the iterated ATC methods if the tolerances are not consistent.
    • Power Flow Solution: Fixed power flow solution when using optimal multiplier. In most situations the optimal multiplier was not being used even when the option to use it was in effect. This could cause the power flow to produce strange results, such as very high voltages, especially when doing PV solutions near the nose of the curve.
    • Power Flow Solution: When using the option to Check Generator Mvar Limits Immediately, generators will only be allowed to hit limits for the first two voltage control loop iterations. After that they will only be allowed to back off limits.
