Open Source Module for the Investigation of the Impact of Electric Vehicles in a Low Voltage Grid

This paper provides an open-source Python-based module overview focused on simulating the integration of electric vehicles in a low voltage grid. This module aims to investigate the possible effects that the integration of electric vehicles could have on the operability of the power network. The electric grid conditions are estimated by analysing line loading, voltage values at the final customer, and transformers' loading. The following tool enables modelling electric grids composed of basic grid elements such as lines, two-winding transformers, predefined load profiles and generated electric vehicle load profiles based on a statistical approach. The module performs time-series simulations through a secondary software, OpenDSS, with result exporting functionality for further analysis, and a graphical user interface.
