Summary:

VFlexP is an open-source tool for simulating and analysing hybrid AC/DC power systems using MATLAB Simulink, based on a vectorised formulation of all variables. Its main contributions are allowing flexible-complexity representations of devices, easy inclusion of new models and the analysis of the state variables’ relevance, aiding in model simplification. It ensures fast initialisation from power-flow analysis and features a user-friendly interface that groups similar power system elements together. This makes VFlexP ideal for detailed, non-linear time simulations of hybrid power systems, despite its current limitation to balanced power systems in d-q representation. The article presenting the features of VFlexP has been presented in IREP'2025 conference and accepted for publication in the IREP'2025 Special Issue of the journal Sustainable Energy, Grids and Networks.
