13.2.9 Pollutants
You can define a new pollutants file here, which can then be loaded into a project from the
Conditions/Pollutant Mix menu.
In the Text field a file reference describing the data record is given, that was entered when
saving the file.
Different values are required for simulating grid connected and stand-alone systems.
Grid Connected Systems
In the first column you need to enter the specific pollutant emissions that occur on
production of the electricity required to supply energy from the grid.
In the second column you need to enter the specific pollutant emissions that are avoided
by feeding PV energy into the grid.
This kind of differentiation is necessary when it can be expected that the grid utility will
use different power plants for producing high and low peak electricity. For example the
energy fed into the grid could suppress basic load electricity production with energy
drawn from the grid occurring during peak times.
Stand-Alone Systems
For stand-alone systems the pollutant emissions for the Back-up Generator are given.
Click on Load to load a new pollutant evaluation file from the database or on Save to save
new specifications to the database.
All emissions files must have the file ending *.emm. The directory that appears on opening
the dialog can be set under Options/Drives.
The database that comes with the programme consists of values from the Integrated
Systems Total Emissions Model (GEMIS), published in 1990 by the German state of Hesse’s
Ministry for the Environment, Energy and Federal Matters.
