gridmeta 1.0.1

A repository for extracting dehydrated metadata for distribution power grid model.

Getting Started with grid-meta

View Full Documentation..

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

🧪 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=3.10
conda activate grid-reducer-env

🚀 Step 2: Install the Project Locally

Install the project.

pip install gridmeta

✅ This will also install all required dependencies.

🛠 Example CLI Usage

You can currently use this package as CLI tool. To see the available commands please use following command.

gridmeta --help

Usage: gridmeta [OPTIONS] COMMAND [ARGS]...

Options:
  --help  Show this message and exit.

Commands:
  extract-opendss-dehydrated-dataset

To extract opendss model dehydrated metadata you can use following command.

gridmeta extract-opendss-dehydrated-dataset -f tests\data\opendss\ieee13\master.dss -o test.json

You can specify privacy flag with -pm option.

gridmeta extract-opendss-dehydrated-dataset -f tests\data\opendss\ieee13\master.dss -pm "low" -o test.json

Make sure to pass appropriate file paths. You can also update model year, state, region type and description from command line. Defaults will be used if these are not provided.

Example

Here is an example of extracted metadata for IEEE 13 opendss model.
