Roseau Load Flow

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
• Advanced built-in plotting tools for network visualization on interactive maps and voltage profile plots
• Real-world distribution network data samples in the library (with more available in the Representative French Power Grids repository)

In addition to the following unique set of features:

• Floating neutrals for loads, sources, and transformers
• Actual four-wire multi-phase modelling with no Kron's reduction and no transformations
• Ideal or impedant ground connections at any point in the network
• Flexible loads with Volt-Watt and Volt-VAr control directly in the Newton loop, which is more stable and results in a faster convergence than with the traditional outer loop approach
• Out-of-the-box support for Single-Wire Earth Return (SWER), American bi-phase systems with center-tapped transformers, zero-sequence modelling, and other non-standard configurations

This project is compatible with Python version 3.12 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/.

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.

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.
