This section describes the options available on the Options tab of the Governor Power Flow dialog. The dialog is accessed by selecting Other > Governor Power Flow from the Other Tools ribbon group on the Tools ribbon tab.
This tab sheet presents the following controls:
Disable Automatic Generation Control
Disables automatic MW generation changes during the power flow solution.
The ACE mismatch tolerance allowed for the Island to be considered solved in terms of generation dispatch.
Island-Based Automatic Generation Control
Select how the generations should be controlled for the dispatch.
- Disabled: The area and super area dispatch settings from the case will be used
- Use Participation Factors of individual generators: Each generator will have it’s own participation factor, and will contribute according to its participation factor divided by the sum of all participation factors of all other generators in the same island.
- Calculate Participation Factors from Area Make Up Power Values: Each area is assigned a "factor" as to how it should participate towards the generation dispatch in the island. This is similar to participation factors for generators. The total percentage the area contributes towards the generation change needed in the island is equal to its individual factor divided by the sum of all area make up power factors. Then within each area, the generator participation factors determine how the area’s percentage is made up of available generation within the area. The area make up power values can be set in the table of areas on the right hand side of the dialog.
- Dispatch using an Injection Group: The island dispatch will be made up by a combination of generators and loads, defined in an injection group that can be selected from the dropdown list.
How should reactive power load change as real power load is ramped?
If you are using an injection group with load as part of the dispatch, then you can specify how the reactive power load should respond as the real power demand of loads changes with the dispatch. The reactive power can either be kept at the starting ratio of real and reactive power of the load, or the MVAR amount can change at each load by a specified power factor.
