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.
