Multiple Scenario ATC Analysis Results: Local Menu Options<br />

The Results page of the Multiple Scenario ATC Analysis is available on the Available Transfer Capability<br />

dialog when selecting the option to Analyze Multiple Scenarios on the Advanced Options tab of the<br />

Available Transfer Capability dialog.<br />

Right-clicking on the table contained on the Results page will bring up a local menu containing several<br />

other options. The first several options are only enabled if a cell that represents a scenario is rightclicked.<br />

These options will perform an operation with respect to the Scenario:<br />

Take me to Scenario …<br />

Implements the changes in the Scenario resulting in a modified system state. Transfer limits are not<br />

calculated.<br />

Determine Transfer Limit For Scenario …<br />

Calculates the ATC for the Scenario, and then sets the system state back to the Initial State.<br />

Determine Transfer Limit for Selected Scenarios<br />

This option is available if multiple scenarios are selected. Multiple scenarios can be selected by<br />

holding down the CTRL key and left-clicking on the desired scenarios. When this option is selected,<br />

transfer limits for all of the highlighted scenarios will be calculated. The system state will be restored<br />

to the Initial State upon completion of all calculations.<br />

Take me to the Transfer Limit For Scenario …<br />

Performs ATC analysis for the Scenario, and then ramps the transfer to the lowest transfer limit<br />

found. If using one of the iterated methods, the transfer limit used for the ramping is the lowest one<br />

that is iteratively found.<br />

Other options on this local menu are not related to the Scenario that has been clicked.<br />

Increase Transfer for Present System State<br />

Increments the transfer level for the present system state by a user-defined amount.<br />

Return to Initial State<br />

Returns the system state to the Initial State. The initial state is the state in memory when the<br />

ATC analysis is started. The initial state is only stored if using one of the iterative ATC Solution<br />

Methods or analyzing Multiple Scenarios. The initial state is also stored when opening the ATC dialog<br />

if an initial state has already been stored.<br />
