Facility Min Operating Factor

Units:	%
Mode:	Input Only
Multi-band:	False
Default Value:	0
Validation Rule:	≥0
Key Property:	No
Description:	Minimum unit level required when operating as a proportion of the maximum
Detail:

Facility Min Operating Factor is the minimum production level required when operating.

How Min Operating Factor is interpreted (as a facility-wide value or unit-by-unit)  depends on the Min Operating Level Global setting. By default it is expressed as a proportion of the unit Max Operating Level. Setting this creates the following constraints:

Production ≥ Units Operating × Max Operating Level × Min Operating Factor

Units Operating integer

Alternatively, it can be the minimum as a function of Installed Capacity, creating the following constraints:

Production ≥ Operating × Max Operating Level × Units

"Operating" binary

Note that the integrality constraint is relaxed if Unit Commitment Optimality is set to "Linear Relaxation" since Units Operating in that case is a continuous variable.

Min Operating Factor Example

Property	Value	Units	Timeslice
Max Operating Level	87	-	M01
Max Operating Level	87	-	M02
Max Operating Level	87	-	M03
Max Operating Level	87	-	M04
Max Operating Level	80	-	M05
Max Operating Level	80	-	M06
Max Operating Level	80	-	M07
Max Operating Level	80	-	M08
Max Operating Level	80	-	M09
Max Operating Level	87	-	M10
Max Operating Level	87	-	M11
Max Operating Level	87	-	M12
Min Operating Factor	40	%

In this example the minimum Production of the facility will always be 40% of the committed capacity.

As an alternative you can specify the Min Operating Level directly.
