Documentation Status

Roseau Load Flow is a powerful load flow solver and static analysis tool that offers:

  • Multi-phase, unbalanced power flow analysis
  • A performance optimized solver written in C++
  • A catalogue of real-world transformer and line models
  • An ergonomic object-oriented Python interface with unit-aware quantities
  • A comprehensive documentation with code examples
  • Real-world distribution network data samples in the library (with more available on request)

In addition to the following unique set of features:

  • Support for floating neutrals for loads and sources
  • Four-wire multi-phase modelling with no Kron's reduction, no transformations, no assumptions on the network topology
    and no implicit earthing everywhere
  • Support for flexible, voltage-dependent, loads directly in the Newton algorithm for better convergence and
    stability

This project is compatible with Python version 3.11 and newer. The
installation instructions will guide you
through the installation process. If you are new to Roseau Load Flow, we recommend you start with the
getting started tutorial. You
can find the complete documentation at https://roseau-load-flow.roseautechnologies.com/.

License

This project is partially open source but using the solver requires a license. The license key
A8C6DA-9405FB-E74FB9-C71C3C-207661-V3 can be used free of charge with networks containing up to 10 buses. To obtain a

Network data

Roseau Load Flow ships with a sample of 20 low-voltage and 20 medium-voltage feeder networks. Each network is provided
with its summer and winter load points.

To go further, you can also use
these 150 distribution networks,
published by Mines Paris Tech in Roseau Load Flow format. Supplied with their
respective coefficients, these representative networks can be used to simulate the entire French distribution network.
