PowerFactory-Tools is a Python package that facilitates the control of PowerFactory, a worldwide used network calculation program. The software provides a well-structured and type- safe interface for PowerFactory, thereby simplifying the development, testing and verification of custom Python scripts. The package also includes a network exporter that converts PowerFactory data into the open-source Power System Data Model format. This enables users to access the nodal admittance matrix of the network, which is restricted in PowerFactory. PowerFactory-Tools also provides type hints and autocomplete suggestions, safe unit handling, and a temporary unit conversion to default values. The package has been utilised in a variety of research projects. This software is a valuable tool for power system engineers and researchers who require network calculations to be automated and streamlined.
