Generator Maintenance

Units:	MW
Mode:	Output Only
Multi-band:	False
Default Value:
Validation Rule:
Key Property:	No
Description:	Capacity lost to maintenance

Input

As an input, Maintenance sets the amount of generation capacity on maintenance outage. This can be defined using a Variable or passed as an input from an Interleaved simulation to coordinate maintenance outages between models.

Output

The definition of the Maintenance output varies by simulation phase:

LT Plan

Generator Maintenance reports the de-rating applied to capacity to account for Maintenance Rate:

Maintenance = ∑ ( b ) ( Maintenance Rate_b × ( Max Capacity - Outage Rating_b

where:

b indexes the bands of Maintenance Rate

PASA

Generator Maintenance is the sum of the user-defined maintenance and the 'idealized' maintenance profile:

Maintenance = Discrete Maintenance + Distributed Maintenance

MT Schedule and ST Schedule

Generator Maintenance reports the megawatt capacity on maintenance from the realized maintenance events (combination of user-defined and those generated by PASA. Thus for any given event:

Maintenance->(Max Capacity - Outage Rating) × Units Out

Note that if MT Schedule Chronology = "Partial" then multiple discrete events may combine together in any given period as a function of the slicing of the load duration curves and thus this profile may then resemble a sculpted de-rating rather than discrete events.
