Min Gen Back Down Penalty
This column is used to provide further refinement to economic flexibility in the modeling of minimum generation segments and also to address LP infeasibility, which can be introduced due to hard minimum generation constraints. When the $/MWh value specified in this column is non-zero, Aurora will use this penalty instead of the global Min Gen Back Down Penalty on the Dispatch and Demand form of Simulation Options. It is used on the minimum segments of Commitment/Must Run resources when the minimum segment is scheduled as running. The objective coefficient becomes (Resource Cost – MinGenBackDown).
For instance, if only the global specification is used, the minimum segments will be backed down (to avoid infeasibility) starting with most expensive resources first. However, this resource-level specification allows more control over which resources are selected to relax below their minimum segments. The higher the value of the Min Gen Back Down Penalty, the less likely the minimum segment will be backed down when there is too much must run generation.
NOTE: When applied to a resource, the resource level Currency Units will be used in conjunction with this value.
NOTE: If the FUEL reference is specified for this variable the value in the Fuel Table will be applied.
NOTE: Inputs can be specified for any time period (annual, monthly, weekly, hourly or sub-hourly). For information on how to specify a time series for a variable, see Entering a Time Series.
