Abstract

This project contributes with the analysis and comparison of the environmental impacts related to the production and usage of low-voltage electric grids under three topologies: DC, AC and hybrid. A python software was developed to simulate losses and optimize component sizing and the management of controllable agent such as batteries and electric cars. A case study was conducted based on a typical mixed consumer with distributed energy sources connected to the RTE. Simulations were done over 20 years with the three topologies and their results were compared. This study finds that a hybrid topology can be an interesting alternative to traditional AC grids since it reduces converter impacts, especially for short cables. However, the optimal topology for a given system can vary according to characteristics such as nominal power, cable length and consumption profile. To determine this behavior, a detailed sensitivity analysis is conducted.
