This dialog is used in the Run Mode to view and modify information associated with a zone record. It displays different information from the Edit Mode version of the zone dialog. To view this dialog, open the Zone Records Display by clicking on Aggregations > Zones in the Model Explorer. Right-click on the zone of interest and choose Show Dialog. The Run Mode Zone Dialog has the following fields:
Zone Number, Zone Name
Number and name of the associated zone. Use either the combo box or the spin arrows to view the different zones.
Find…
If you do not know the exact zone number you are looking for, you can click this button to open the advanced search engine.
Labels
To assign alternative identifying labels to the zone, click the Labels button, which will open the Label Manager Dialog listing all the labels or aliases assigned for the selected zone.
The rest of the Run Mode Zone Dialog is divided into multiple pages:
Information
Load and Generation
Real and reactive load, generation, shunts, losses, and interchange for the zone.
These two fields show the total available MW reserve for generators in the zone that are on AGC and have nonzero participation factors. In other words, these fields show the total MW by which the generation in the zone can be increased or decreased using only generation that is presently on-line. The generator status, AGC status, and participation factor can be changed on the Generator Records Display.
Tie Lines
Zone Tie Lines
The Zone Tie Line Table identifies the flows on all of the zone's ties to other zones.
To determine the total loss for a zone, losses for tie-lines between zones are assigned to the zone in which the terminal bus that is NOT the metered bus is contained. The Metered End field for a branch determines which of the terminals is metered.
Average LMP for Zone
The computed average locational marginal price of all buses contained in the zone.
LMP Standard Deviation
The standard deviation of the locational marginal price for all buses contained in the zone.
Minimum LMP
The minimum locational marginal price of all the buses in the zone.
Maximum LMP
The maximum locational marginal price of all the buses in the zone.
Reserve Requirement Curves
These options are only available with the OPF Reserves add-on. More information about these options can be found in the Area and Zone OPF Reserve Requirement Curves topic.
Zone Buses, Zone Gens, Zone Loads, Zone Switched Shunts
These pages show the case information display with the buses, generators, loads and switched shunts assigned to the zone.
Custom
The Custom Page of the Zone Information dialog displays custom numbers or strings defined with the viewed zone. The Memo box is simply a location to log information about the zone. To log information about the zone, simply start typing your information or comments about the zone in the memo box.
