Welcome to the ZEN-garden! ZEN-garden is an optimization framework for energy transition pathways. It is currently used to model the electricity system, hydrogen value chains, and carbon capture, storage and utilization (CCUS) value chains. However, it is designed to be modular and flexible, and can be extended to model other types of energy systems, value chains or other network-based systems.
ZEN-garden is developed by the Reliability and Risk Engineering Laboratory at ETH Zurich.
To get started with ZEN-garden, you can follow the instructions in the installation guide.
If you want to use ZEN-garden without working on the codebase, run the following command:
pip install zen-gardenIf you want to work on the codebase, fork and clone the repository and install the package in editable mode. More information on how to install the package in editable mode can be found in the installation guide.
Please refer to the documentation of the ZEN-garden framework on Read-the-Docs.
Additionally, example datasets are available in the dataset_examples folder and described in the documentation.
Review recent modifications outlined in the changelog.
