Available FMUs

CYME FMU

The CYME FMU can be downloaded from here.

An example of model description is provided below. A few things are required for the CYME FMU to operate properly:

• a parameter called _configurationFileName pointing to a JSON configuration file (including the feeder filename).
• inputs and outputs should have the following format {network ID}!{node/load ID}!{keyword}, where keyword can be KW, KVAR, or Vpu.

The JSON configuration file should have the following format:

{
  "model_filename": "IEEE_34_node_test_feeder.sxst",
  "total_load_filename":"total_load.csv",
  "substation_network":"IEEE34NODES"
}

PandaPower FMU

The PandaPower FMU can be downloaded here.

An example of model description is provided below. Note that this FMU does not require any configuration file since the feeder model is set within the FMU.

The format for inputs and outputs is defined as {keyword}_{node id} where keyword can be KW, KVAR, and Vpu.

Python FMU Template

A simple template for creating Python FMU can be found here.

Note: If the name of the FMU is set to “NAME” in the XML file then the Python file with the “exchange” function should be named “NAME_wrapper.py”

Note: The FMU needs to be recompiled anytime it is moved to a different folder or if any inputs/outputs names changed.
