Generator Efficiency Incr
| Units: | MW/MW |
| Mode: | Input Only |
| Multi-band: | True |
| Default Value: | 1 |
| Validation Rule: | Any Value |
| Key Property: | No |
| Description: | Efficiency of hydro generation |
| Detail: |
Generator Efficiency Incr is the incremental efficiency of hydro generation. It is combined with Load Point in multiple bands to define an efficiency function across the range of generation. The 'no-load efficiency' is defined using Efficiency Base.
Example (using metric units) The purpose of this example is to show you how PLEXOS calculates Efficiency by given table 1. Picture 1, 2 and 4 is the process result of calculation.
| Property | Value | Units | Band |
|---|---|---|---|
| Units | 1 | - | 1 |
| Max Capacity | 60 | MW | 1 |
| Load Point | 20 | MW | 1 |
| Load Point | 40 | MW | 2 |
| Load Point | 60 | MW | 3 |
| Efficiency Base | 58 | cumec | 1 |
| Efficiency Incr | 0.5 | MW/cumec | 1 |
| Efficiency Incr | 0.48 | MW/cumec | 2 |
| Efficiency Incr | 0.42 | MW/cumec | 3 |
