Items

Item	Purpose
Name	Name of Constraint
Included	Included Status (checked when Constraint will be included in dispatch)
Constraint Type	Can be Permanent Temporary Outage
Season	Can be Summer Winter Both
Default Formula	Used as the default formula when applied in the Forecast
Default Limit	Used as the default limit value when applied in the Forecast

NOTE: EMarketOffer flags an Equation Constraint as Active if the grid data files contains a constraint starting before or during the Forecast Effective Date Range and ending during or after the Effective Date Range.

Usage

>> Double-click on a row to open the Edit Equation Constraint Window where Constraint details can be edited

>> To add a new Equation Constraint:

Click on any row in the Equation Constraints Data Grid and press the <Insert> key. This creates an empty row at the top of the Grid labelled " _ new _ ". Details of the Constraint can be entered by bringing up the Edit Equation Constraint Window by double-clicking the empty row.

>> To delete an existing Circuit:

Click on the row in the Circuit Data Grid containing the Circuit you want to delete and press the <DELETE> key. A dialogue box asking you to confirm the delete operation will appear.

NOTE: Deleting a Constraint also deletes any re-ratings data associated with the Constraint at the time of deletion.

The Edit Equation Constraints Window

Access

Double-clicking an Equation Constraint name in the Loaded Data Summary Panel of either the Forecast Definition or Powerflow Case Definition Windows.

Purpose

To manually add, delete and modify the applications of a specific Equation Constraint throughout the Effective Date Range.

Components
