About OptiWindNet¶

OptiWindNet is an electrical network design tool for offshore wind farms developed at the Technical University of Denmark – DTU. The package offers a framework to obtain optimal or near-optimal cable routes for a given turbine layout within the cable-laying boundaries. It provides high-level access to heuristic, meta-heuristic and mathematical optimization approaches to the problem.

The tool is distributed as an open-source Python package that is suitable for use within an interactive Python session (e.g. Jupyter notebook). Alternatively, OptiWindNet’s API can be invoked directly from another application.

What can OptiWindNet do?¶

Optimize the network of array cables;
Route the cables so as to avoid crossings;
Assign cable types and calculate network costs;
Use different optimization approaches according to the preferred time/quality trade-off;
Employ user-provided models and objective functions within the mathematical optimization approach.

Getting Started¶

Setup your Python environment and check the Quickstart to begin using OptiWindNet.
