Generator Ramp Down Point

Units:MW
Mode:Input Only
Multi-band:True
Default Value:1E+30
Validation Rule:≥0
Key Property:No
Description:Load point for use with multi-band Max Ramp Down constraints

Generator Ramp Down Point is a multi-band property that defines the load point for use with multi-band Max Ramp Down constraints. These should be defined with equal number of bands of Max Ramp Down as in the following example. The ramp limit in the band applies up to the point defined in the band.

Example:

PropertyValueUnitsBand
Max Capacity1000MW1
Max Ramp Down2MW/min.1
Max Ramp Down3MW/min.2
Max Ramp Down3.5MW/min.3
Max Ramp Down2MW/min.4
Ramp Down Point250MW/min.1
Ramp Down Point500MW/min.2
Ramp Down Point750MW/min.3
Ramp Down Point1000MW/min.4
Max Ramp Down Penalty100$/MW1

Note that the ramp penalty is also multi-band which allows different penalties for different generation levels.
