nopywer (pronounced /noʊ.paɪ.wɛr/: “no-pie-wer”, as in no+ python + power) is a python package to design 3-phases, islanded power grids using automatic grid design features and analysis tools.

Nopywer key features include:

• Design power grids using graph optimization algorithms.
• Analyze current flow and voltage drop to ensure safe grid operation.
• Verify material availability against inventory to plan construction.
• Interact with a map to edit the power grid from your browser - no third-party app necessary
• Open-source code (GPL-3.0 license) : contributions welcome !

Nopywer has been successfully used to design several power grids, as illustred by the following figure.

Example of a real-case scenario: on this map, houses represent power loads at specific geographic coordinates; their sizes scale with their power needs. In this case, two 3-phases islanded grids were designed to provide power to 61 loads (totalling 195kW) from two generators.

Illustration of the map accessible from the browser (this work is currently under active development).

This site will soon be populated with examples and tutorials about how to design power grids yourself, stayed tuned!
