PyDSS#

About PyDSS#

PyDSS is a Python wrapper for OpenDSS that aims to expand upon its organizational, analytical, and visualization capabilities with these features:

Allows the user to develop custom control algorithms for specific circuit elements and run them at each simulation time step.
Provides co-simulation integration with HELICS.
Provides extension modules to facilitate Monte Carlo studies in distribution system domain and automated post-processing of results.
Automates collection and analysis of circuit element results at each simulation time step.
Flexible architecture allows users to develop extensions.

PyDSS uses opendssdirect.py (https://pypi.org/project/OpenDSSDirect.py/) to communicate with OpenDSS.

Installation#

Recommendation: Install PyDSS in an Anaconda virtual environment. Specific dependent packages like shapely will only install successfully on Windows with conda.

Here is an example conda command:

$ conda create -n pydss python=3.9

Install shapely with conda. pip, particularly on Windows, often fails to install its dependent libraries.

$ conda install shapely

Install the latest supported PyDSS version with this command:

$ pip install nrel-pydss

Alternatively, to get the lastest code from the master branch:

$ git clone https://github.com/NREL/PyDSS
$ pip install -e PyDSS

Confirm the installation with this command. It should print the available commands:

$ pydss --help

Running PyDSS#

Refer to the Quick Start Guide for basic instructions on how to configure PyDSS to run a simulation with an existing OpenDSS model.

Refer to Tutorial for in-depth instructions on how to customize a PyDSS project.
