Initial Online Hours Column
Column Type = Text
The Initial Online Hours column is used to specify how long a Commitment Unit has been online or offline.
NOTE: This is only used in the Commitment Optimization logic.
-
A positive integer indicates that the unit has been online for that many hours at the first dispatch hour of the current study. For example, if a unit with a Min Up Time of 16 hours had a value of 8 in this column, then the model will commit the unit during the first hour of the study and assume that it must stay online for at least the next 8 hours.
-
A negative number indicates that the unit has been offline for that many hours at the first dispatch hour of the current study. In this case, if the unit had a Min Down Time of 12 hours and the value in this column was -10, the model would not be allowed to commit the unit during the first two hours of the simulation until the Min Down Time of 12 was reached.
-
An entry of NULL or zero allows the model full freedom to commit or not commit the unit at the start of the study.
NOTE: Specify inputs for any time period (annually, monthly, weekly, hourly, or sub-hourly). For information on specifying a variable's time series, see Entering a Time Series.
When using time series references, the value will only be resolved and used for the first dispatch hour of the study's first dispatch day.
