Parameter Name Column
Column Type = Text

The Parameter Name column is used to enter the parameter/setting that is set in the Parameter Value column.  Available options are listed below.

USE CATEGORY	PARAMETER NAME	VALUE FORMAT	DESCRIPTION
Commitment Optimization	Allow Non Spin In Commit Op	Boolean	True allows non spin resources in commitment optimization.  If False, non spin constraints will not be explicitly modeled in commitment optimization.
	Commit Op Forecast Cost Adjust	Numeric	User override for the forecast cost calculation.  The default is currently is Number of Periods in First Day/Number of Periods in Forecast Day.
	Include Storage In Spinning Constraints	Boolean	True will use storage resources in the spinning constraint in commitment optimization.
	Use Hourly Dispatch After Commitment	Boolean	True turns on hourly dispatch after commitment.
General	Allow Negative Fuel Prices	Boolean	If True, negative fuel prices will be allowed.
	Default Optimize Annual Operation	Boolean	A global setting for all storage groups instead of setting up the Storage table and using the Optimize Annual Operation column.
	Demand Curve Use Interpolation	Boolean	When True, interpolation will be used to calculate demand curve capacity prices.
	Fix Ramp Constraints	Boolean	When True, this switch fixes ramp resources at their output before the final prices are determined.
	Gurobi PRM Name	String	When specified, Aurora will search for the .prm file with the given name next to the running project. If not found, Aurora will search for Gurobi.prm next to the project. If a valid file is found, then Aurora will use the parameters for the study.
	Increased Curtailment Cost	Boolean	When False, the curtailment cost will not be increased for the solver's purpose. This is only suggested for cases that have high amounts of curtailment due to lack of capacity. Other settings may need to be adjusted in conjunction with this parameter (i.e, solution precision).
	IO Curve In MMBtu	Boolean	When True, the units for heat rate IO Curve coefficients will be assumed to be in MMBtu instead of the default Btu.
	Keep Back Down Penalty	Boolean	When True, this will keep the back down penalty in the formulation when Remove Penalty Adders from Pricing is selected.
	Percent Committed For All Output	Boolean	When True, Percent_Commited will be reported for all resources that have output.
	Relax Min Start Hour	Boolean	A value of True relaxes the Minimum Capacity on the start hour of resources.
	Remove Random Resource Adjustment	Boolean	When set to True, the random adder that is applied to the dispatch cost of resources will not be used. This random adder is beneficial when there are resources with nearly identical costs and helps to differentiate resources. Repeatability of results may be impacted when not using adder.
	Skip Segment Sorting	Boolean	If True, heat rate segments will not be sorted.
	Solver Threads	Numeric	This is an override for the number of threads that the solver (Gurobi or Mosek) can use when optimizing. By default it will use all of the threads on a machine. Using this parameter can be helpful in reproducing results on different machines that have a different number of cores.
	Use Charging Resource For Charging Cost	Boolean	When true, the incremental cost of the storage charging resource will be used to calculate the Storage Charging Cost. If multiple charging resources are defined, a weighted cost is calculated and used.
	Use Single Output Constraint	Boolean	If True, one constraint will be used for all resource segments. If set to False one constraint will be used per segment.
LT	Annual Curtailment Constraint Limit	Numeric	User override for the allowed number of annual curtailment constraints in LT.
	Choose Lowest Total Cost for RMT	Boolean	When True, Aurora will choose the iteration with the lowest total cost for the final RMT.
	Energy Only Start RM	Numeric	User-defined starting reserve margin target to be used in the first iteration in LT when reserve margins are not being used.
	Fix Peak Credit Vals Early	Boolean	True sets peak credit values in the dynamic peak credit logic one iteration earlier and will not update them in subsequent iterations.
	Include Ancillary in LT	Boolean	When True, ancillary constraints will be included in LT MIP formulation.
	Include Spin In Curtailment Constraint	Boolean	True will include spin requirements in LT curtailment constraint.
	LDC Solver Method	String	Set the LDC solver method used in the simulation to Interior Point or Simplex.
	Limit By Output	Boolean	When True, the bounds of storage operation LT MIP when using the LDC method will be limited by the chronological output.
	LT Buckets	Numeric	User override to set the number of LT "buckets", or dispatch intervals, used in the study.
	LT LP File Location	String	Enter the location to write the LP files for an LT study.  Must be the full path name, e.g., "C:\AURORAxmp".
	Use Commitment Feedback in LDC Solve	Boolean	True uses a feedback loop to refine commitment decisions for the purposes of the LDC solve in the constrained dispatch logic, which can give LDC results that are more in line with the chronological solution, but using the feedback loop will increase the run time.
	Use LT Curtailment Constraints	Boolean	When True, constraints to limit the demand curtailment will be used in the LT MIP.
Nodal	Contingency Islanded Bus Handling	Numeric	This controls what Aurora does when it encounters a contingency which creates one of more islands of individual buses. A value of 0 means that Aurora makes no attempt to adjust the contingency to fix any islanded buses (this is the default). A value of 1 means that it will attempt to fix only transmission buses (those without load or generation) which are islanded by removing one or more contingent branches from the contingency definition. A value of 2 means that it will attempt to fix all buses which are islanded by removing one or more contingent branches. Note that this processing is done up front whether or not the checkbox "Allow Contingency Islanding" checkbox is selected
	LODF CSV Location	String	Enter the location to write the LODF files for nodal runs.  Must be the full path name, e.g., "C:\AURORAxmp".
	LODF Tolerance	Numeric	Sets a tolerance value for LODFs.  Values below this threshold will not be used in the contingency constraints.
	Remove Balance Relaxation Effect	Boolean	When True, the relaxation price for the nodal balance constraint will not directly affect the final prices.
	Remove DC Line Relax Cost	Boolean	When True, this removes the DC Line relaxation cost from the final solve in a nodal study.
	Reset Nodal Constraints Monthly	Boolean	A value of True resets nodal constraints every month.
	Shift Factor CSV Location	String	Enter the location to write the Shift Factor files for nodal runs using shift factors.  Must be the full path name, e.g., "C:\AURORAxmp".
	Use Int Var For DC	Boolean	When True, integer variables (on/off) will be used to model nodal  DC Lines instead of continuous variables.
Portfolio	Use LP in Port Op	Boolean	When True, Portfolio Optimization studies will use LP approximation.
