Max Up Time
Column Type = Text
The Max Up Time column allows users to specify the maximum number of hours a resource can remain online once committed. This value is ignored if Non-Cycling is zero.
NOTES:
- The Max Up Time feature can only be used with commitment optimization.
- If the Max Up Time is set to zero or left NULL/blank, Aurora will ignore this constraint.
- If a FUEL reference is provided, the corresponding value from the Fuels Table will be applied.
- This column only accepts values in hours or a FUEL reference. Time series references are not allowed.
- If a resource has only a Max Up Time limit without a Min Up Time limit, setting it to 1 hour is recommended.
- If the Max Up Time value is smaller than the sampling interval duration, Aurora assumes that the resource satisfies the Max Up Time limit during the non-sampled hours and hence may decommit on every sampled hour.
Example:
Max up time = 12 hrs,
Sampling resolution on dispatch days and look ahead periods = Noon hour, Every Day, Every Week
Output expected:
The resource is assumed to be committed during 1st Hr, running until the 12th Hr (1st Hr to 12th Hr are the non-sampled hours). It then decommits during the 13th Hr (the Noon hour). Thus, the resource decommits at every Noon Hr.
Hence, it is recommended to use a higher resolution sampling interval (say every 8th hour on dispatch days or look-ahead periods for a Max Up Time of 12 hrs) so that the sampling interval duration is smaller than the Max Up Time.
