Detection of LP Cycling
This option allows for advanced tweaking of when cycling is detected in the LP. It is recommended that users leave the default settings in place.
Minimum Number of Degenerate Iterations to Assume Cycling
To prevent inaccurate identification of cycling in the LP solution, the minimum number of degenerate iterations before cycling is identified can be specified manually in this box.
Minimum Number of Degenerate Iterations Multiplied by Number of Tableau Rows
To prevent inaccurate identification of cycling in the LP solution, the minimum number of degenerate iterations as a multiple of the number of tableau rows can be specified manually in this box.
Number of Sequential Degenerate Iterations for Last Case
This displays the number of degenerate iterations detected when performing the most recent OPF solution.
Power Flow Recalculation
Choose one of the options to determine how often the power flow is resolved. The three options are, "When total generator MW change > than tolerance"; "After each LP solution"; and "Only at end of LP OPF". If the power flow is not resolved, linear sensitivities are used to determine which constraints enter the LP tableau.
Total Generator Change Tolerance (MW)
Specifies the total generator change tolerance. The default is 500 MW.
After each LP solution
Resolves the power flow upon completion of each LP solution
Only at end of LP OPF
Resolves the power flow only after the LP OPF has completed.
