cosim-toolbox 1.0.1

Python support for the CoSimulation Toolbox

Co-Simulation Toolbox to push advances in the field.

Installation

cosim_toolbox can be installed using pip:

$ pip install cosim_toolbox

However, in order to be useful, cosim_toolbox needs custom versions of GridLAB-D and other federates that work with HELICS. It also requires Python 3.10 or later, with HELICS, NumPy, MongoDB, Pandas, and Psycopg. There is reposistory of the complete Co-Simulation for Windows, Linux and Mac OS X on GitHub. A Docker version is also available for users.

Development Work Flow for cosim_toolbox

• From this directory, ‘pip install -e .’ points Python to this cloned repository for any calls to cosim_toolbox functions

• See the https://github.com/pnnl/cst for a roadmap of existing Python source files, and some documentation. Any changes or additions to the code need to be made in this directory.

• Run tests from any other directory on this computer

• When ready, edit the cosim_toolbox version number and dependencies in setup.py

• To deploy follow the instructions in the Python Packaging Guide:

  1. Create an account on PyPI if you haven’t yet.

  2. Install twine and build: pip install twine build

  3. Create the source distribution, change to ‘src’ directory execute: python3 -m build .

  4. Check your distribution files for errors: twine check dist/*

  5. (Optional) Upload to the PyPI test server first (note: separate user registration required): twine upload –repository-url https://test.pypi.org/legacy/ dist/*

  6. Upload to PyPI: twine upload dist/*

• Any user gets the changes with ‘pip install cosim_toolbox –upgrade’

• Use ‘pip show cosim_toolbox’ to verify the version and location on your computer

Using Co-Simulation Toolbox

This is a developer’s platform for electric power grid research. See http://cosimtoolbox.readthedocs.io/en/latest/ for user instructions, and https://[github]/copper for source code.
