Set Participation Factors...
Press this button to open the Generator Participation Factors Dialog, which gives you control over how the participation factor for each generating unit is defined. If you decide not to prescribe participation factors using this button, the existing participation factors defined with each generator will be used. This button will be enabled only if the area has been set to Participation Factor area control.
Area Slack Bus Number
Identifies which bus to model as the area’s slack bus.
Injection Group Area Slack
An additional area generation control option that can be utilized is the ability for Simulator to use a defined injection group as the sink for Area Slack control. When an injection group is selected, and the area is set on Area Slack control, any needed injection changes in the area will be accounted for by the devices in the injection group.
Some typical injection group options are also available here for handling the injection group dispatching during the Injection Group Area Slack Control. These options include:
Allow only AGC gen/load to vary:
Only generators and loads in the injection group that are designated as available for AGC control will be allowed to participate in injection changes.
Enforce generator MW limits (ignore case and area options):
Generators in the injection group can be designated to enforce their MW limits independent of the global case and area options for generator MW limit enforcement.
Do not allow negative loads:
If loads are decreasing demand as part of an injection group area dispatch, you can specify whether or not those loads should be allowed to go below 0 demand.
How should reactive power load change as real power load is ramped?
You can choose to keep the ratio of real and reactive power constant for each load that is included in the injection group, or you can specify a constant power factor that the MVAR value will be determined from when the MW value is changed.
Injection groups have their own set of options that can override the default options on this dialog if they are in use. See the Injection Group Specific Scaling Options topic for more information.
