| Description: | Conversion rate of generator heat input to waste heat input. |
| Detail: |
Market Heat Generators Conversion Rate is the incremental rate of conversion from heat input to the generator to waste heat output.
This property is allowed to be multi-band so that you can match the conversion rate with the generator heat rate model.
Example:
| Generator | Property | Value | Units |
|---|---|---|---|
| G1 | Heat Rate | 8.5 | GJ/MWh |
| Market | Generator | Property | Value | Units |
|---|---|---|---|---|
| District Heating | G1 | Conversion Rate | 0.29 | GJ/GJ |
In this example the generator has a constant heat rate of 8.5. This is an equivalent efficiency of 3.6 / 8.5 = 42%. Thus the gross waste heat is 58%. Assuming that half of this is lost before it can be used in heating the conversion rate to usable heat is 0.5 0.58 = 0.29.
Example:
| Generator | Property | Value | Units | Band |
|---|---|---|---|---|
| G1 | Load Point | 40 | MW | 1 |
| G1 | Load Point | 55 | MW | 2 |
| G1 | Load Point | 70 | MW | 3 |
| G1 | Load Point | 85 | MW | 4 |
| G1 | Load Point | 100 | MW | 5 |
| G1 | Heat Rate Incr | 8.2 | GJ/MWh | 1 |
| G1 | Heat Rate Incr | 8.4 | GJ/MWh | 2 |
| G1 | Heat Rate Incr | 8.5 | GJ/MWh | 3 |
| G1 | Heat Rate Incr | 8.6 | GJ/MWh | 4 |
| G1 | Heat Rate Incr | 9.0 | GJ/MWh | 5 |
| Market | Generator | Property | Value | Units | Band |
|---|---|---|---|---|---|
| District Heating | G1 | Conversion Rate | 0.28 | GJ/GJ | 1 |
| District Heating | G1 | Conversion Rate | 0.285 | GJ/GJ | 2 |
| District Heating | G1 | Conversion Rate | 0.29 | GJ/GJ | 3 |
| District Heating | G1 | Conversion Rate | 0.29 | GJ/GJ | 4 |
| District Heating | G1 | Conversion Rate | 0.3 | GJ/GJ | 5 |
This example shows how the conversion rate can be specified for each band of a multi-band heat rate model. When you define multiple bands for the conversion rate you must define the same number of bands for conversion as you have load points.
