OPF Options: LP Basic Variables
The OPF Dialog, LP Basic Variables page displays the basic variables associated with the final LP solution. This page is usually only of interest to users interested in the specifics of the LP solution. Right click anywhere in the display to copy a portion or all of the display to the Window's clipboard, or to print the results.
The display lists each of the basic variables, showing the following fields for each:
ID
Basic variable identifier.
Original Value
The initial value of the basic LP variable before the OPF optimization.
Value
The final value of the basic LP variable after the OPF optimization.
Delta Value
The difference between the original value field and the value of the basic variable.
Basic Var
Shows the indices of the basic variables in the LP basis.
Cost(Up)
The cost associated with increasing the basic variable.
Down Range
The available range to decrease the basic variable before a new constraint is hit.
Up Range
The available range to increase the basic variable before a new constraint is hit.
