Features and Improvements

  • Available Transfer Capability (ATC) Tool: Added new fields for a TransferLimiter object under the folder named Contingency Single Element. All of these field will be blank if there is no associated contingency or if the contingency has more than on ContingencyElement in it. If the associated contingency has only one contingency element, then it will show the field of that single ContingencyElement.
  • Bus View and Substation View Onelines: Modified the Substation View so that it can use the exact same customizations as the Bus View. The substation view customization is much more limited though as it will only use the customizations for Branch Fields. The other fields (Bus, Gen, Load, Shunt) are all still visible on the dialog specifying the customization, but they are not used on the Subview. The customizations of Subview and Busview are share between the two views, so editing them in one location is also editing them in the other.
  • Case Information Displays: Added two new fields to a Substation, Area, and Zone to show a space-delimited list of Nominal kVs in the substation. Useful to show on oneline diagrams and the substation view.
  • Case Information Displays: Added ability to do column contouring on all matrix case information displays.
  • Contingency Analysis Tool: Added new fields for a Contingency object under the folder named Single Element. All of these fields will be blank if the contingency has more than one ContingencyElement in it. If the contingency has only one contingency element, then it will show the field of that single ContingencyElement.
  • General: Made improvements to ensure that the message log is not degrading software performance when the message log is not visible.
  • Optimal Power Flow (OPF): Added a new option in OPF to "Distribute Change Among Equal Cost Generators". When a group of controls have an identical cost and also identical sensitivities on all binding constraints, then the OPF algorithm will now proportionally move the controls between the breakpoints of the cost curve instead of simply picking the generator with the minimum bus number first.
