Welcome! Follow the steps below to get grid-reducer up and running locally.
We recommend using a Python virtual environment for a clean install 🔒🐍.

This software is being provided as a prototype only. For your intended use, it is your responsibility to independently validate the results in accordance with your applicable software quality assurance program.

🧪 Step 1: Set Up a Python Environment

To avoid dependency conflicts, create and activate a virtual environment.

You can use any tool of your choice — here are a few popular options:

🟢 Option A: Using venv (Standard Library)

python3 -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

🔵 Option B: Using conda

conda create -n grid-reducer-env python=3.11
conda activate grid-reducer-env

🚀 Step 2: Install the Project Locally

Install the project:

pip install grid_reducer

✅ This will also install all required dependencies.

🛠 Example CLI Usage

Once installed, you can use command line interface. Run grid --help to see all the available command options.

Here is a minimal example to reduce OpenDSS model.

grid reduce -f Master.dss

Example Python Usage

You can also reduce the feeder model through python scripts.

Here is a minimal example to reduce OpenDSS feeder model using Python Script.

from pathlib import Path

from grid_reducer.reducer import OpenDSSModelReducer

file_path = "master.dss"
reducer = OpenDSSModelReducer(master_dss_file=file_path)
reduced_ckt = reducer.reduce(transform_coordinate=True)

out_folder = Path("outputs")
out_folder.mkdir(parents=True, exist_ok=True)
original_circuit_file = out_folder / "original_ckt.dss"
reduced_circuit_file = out_folder / "reduced_ckt.dss"
reducer.export_original_ckt(original_circuit_file)
reducer.export(reduced_ckt, reduced_circuit_file)

📌 Notes

• This is the recommended way to use the project:

pip install grid-reducer

• If you want your local changes to the code to be applied immediately (without needing to reinstall your package each time), use an “editable” install by running:

pip install -e .
