Heat Plant Max Ramp Up
| Units: | GJ/h (Metric), MMBtu/h (U.S. Imperial) |
| Mode: | Input Only |
| Multi-band: | False |
| Default Value: | 1E+30 |
| Validation Rule: | ≥0 |
| Key Property: | No |
| Description: | Maximum ramp up rate |
| Detail: |
heat plant Max Ramp Up sets a limit on the amount that generation can increase and is expressed as the maximum ramp up rate in megawatts per minute. This limit applies for Heat production ranges between Min Stable Level and Max Capacity.
For multi-unit generating stations the available ramp up is defined as:
Max Ramp Up (station) = Units Producing Heat × Max Ramp UpBy default the ramping limit is a hard constraint meaning that no violation is allowed.
Example:
| Property | Value | Units |
|---|---|---|
| Units | 1 | - |
| Max Capacity | 100 | GJ |
| Min Stable Level | 40 | GJ |
| Fuel Price | 5 | $/GJ |
| Heat Rate | 10 | GJ/GJ |
| Max Ramp Up | 0.5 | GJ/hour |
| Max Ramp Down | 0.5 | GJ/hour. |
To model the running up period where HeatProduction is between zero and Min Stable Level use either the Start Profile or Run Up Rate properties.
