zen-creator 1.4.0

ZEN-creator allows for the creation and management of datasets for ZEN-garden.

ZEN-creator

Lightweight utilities for creating and managing ZEN energy-system models and associated datasets. Full developer and user documentation is available online.

Quick start

Installation (recommended)

• Create the conda environment included with the repository:

conda env create -f zen_creator_env.yml
conda activate zen-creator-env

• Or install in editable mode with pip:

python -m pip install -e .

Basic usage

Programmatic usage is the recommended way to build and manipulate ZEN models. The central entry point is the Model class which can be constructed in several ways: directly, from a configuration file, or by loading an existing ZEN-garden input folder.

from pathlib import Path
from zen_creator.model import Model

# 1) Create a model from a configuration file
model = Model.from_config(Path("config.yaml"))
model.build()
model.validate()
model.write()

# 2) Load an existing ZEN-garden input folder and update
existing = Path("existing_model")
model2 = Model.from_existing(existing)
model2.name = "updated_model"
model2.build()
model2.write()

# 3) Create an empty model and add sectors/elements programmatically
m = Model()
m.add_sector_by_name("electricity")
m.add_element_by_name("electricity", generic="carrier")
m.build()

Useful properties

• model.carriers, model.technologies: dictionaries of elements
• model.output_path: path where the model will be written
