CGMES2PGM-Converter

cgmes2pgm_converter provides a library to convert Common Grid Model Exchange Standard (CGMES) datasets to PowerGridModel format. It was designed to apply the PGM State Estimation on a CGMES dataset. The CGMES dataset is fetched from a SPARQL endpoint and converted to a PGM dataset. This converter works with CGMES 3.0 / CIM 100 datasets, as well as CGMES 2.4 / CIM 16 datasets.

Methods to substitute additional measurements are included as well to improve state estimation (e.g. passive nodes). cgmes2pgm_suite provides additional tools for working with CGMES and PGM.

Getting Started

The package can be installed from PyPI using pip:

pip install cgmes2pgm_converter

Set up the CGMES-Model

The CGMES-Model needs to be imported as a dataset into a triplestore providing a SPARQL endpoint (e.g. Apache Jena Fuseki).

Currently, the CGMES model needs to be stored in the default graph of the dataset. This approach may be updated in future versions.

Conversion

from cgmes2pgm_converter import CgmesToPgmConverter, CgmesDataset

dataset = CgmesDataset(
    base_url="http://localhost:3030/dataset_name",
    cim_namespace="http://iec.ch/TC57/2013/CIM-schema-cim16#", # for CGMES 2.4
    # "http://iec.ch/TC57/CIM100#", # for CGMES 3.0
)

converter = CgmesToPgmConverter(datasource=dataset)
input_data, extra_info = converter.convert()

See cgmes2pgm_suite for an complete example of how to use the converter.

Supported CGMES Classes

The following list of CGMES classes is supported by the converter:

• All Branches (ACLineSegment, EquivalentBranch)
• Links (Switch, Breaker, Disconnector)
• Transformers (2-Winding, 3-Winding)
  • RatioTapchanger
  • PhaseTapChangerTabular
  • PhaseTapChangerLinear, -Symmetrical, -Asymmetrical
• Measurements (P, Q, U, I*)
• Generators & Loads
  • SynchronousMachine, AsynchronousMachine
  • ExternalNEtworkInjection
  • EnergyConsumer
  • StaticVarCompensator
• Shunts (Linear-, NonlinearShuntCompensator)
• DC Components
  • CsConverter, VsConverter
  • Replaced by loads since PGM does not support DC Components

* Used to create Q-measurements
