Available Transfer Capability (ATC) Analysis

 

The ATC Analysis tool is only available if you have purchased the ATC add-on to the base Simulator package. Contact PowerWorld Corporation for details about ordering the ATC version of Simulator.

 

Available Transfer Capability (ATC) analysis determines the maximum incremental MW transfer possible between two parts of a power system without violating any specified limits. This transfer can be between two areas in the system and can also be customized to specific groups of system devices.

 

Simulator’s ATC analysis makes use of several tools that are available elsewhere in Simulator. These include:

• Power Transfer Distribution Factors (PTDFs): determine the linear impact of a transfer (or changes in power injection) on the elements of the power system.
• Line Outage Distribution Factors (LODFs): determine the linear impact of a line outage on the elements of the power system.
• Contingency Analysis: studies the impact of a list of contingencies on the power system.
• Limit Monitoring Settings: control which elements of the system are monitored for limit violations.

You do not directly use these other tools when using Simulator’s ATC analysis tool, but Simulator uses the settings and algorithms in the background to determine ATC. Thus, it is helpful to be knowledgeable on their use, as it will help you in interpreting the results of an ATC analysis.

 

• Simulator provides three methods of determining the ATC for a transfer direction. See : ATC Solution Methods
