Welcome to the Roseau Load Flow documentation¶

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

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.

We also maintain a set of 150 MV feeders representative of the French distribution system at https://github.com/RoseauTechnologies/Representative_French_Power_Grids. Each feeder is modeled with its downstream LV networks. The repository also contains the cluster size that indicates how representative is each network of the French distribution system. These networks are the result of the study Representative MV feeders for the analysis of French distribution networks, made and published by Mines Paris Tech.

More details are given in the Catalogues page.
