The calculation of MW*Distance quantities can be customized in a number of ways. These options are set from the MW*Distance Options Dialog.
Include Tie Lines Only
If this box is checked, then the only branches that contribute to the MW*Distance calculation are those that tie two areas together. Otherwise, both tie lines and lines internal to areas and zones are included in the calculation. In the latter case, tie lines are assumed to belong to the area that owns the metered end of the branch.
Internal Flows
If you choose to include both tie line flows and flows internal to areas and zones in calculating MW*Distance quantities, you have two options for how to treat internal flows. You can ignore flows resulting from the transaction that flow in the reverse direction of the existing flow on a branch by checking the Include flow increases only checkbox. You can also choose to treat all such counterflows as negative contributions to an area or zone’s MW * Distance value by checking the Deduct flow reductions checkbox.
Omit Branches
To omit branches for which the PTDF corresponding to the transaction is less than a specified value, specify a nonzero percentage in this textbox.
