Abstract

In the context of the energy transition and sustainable mobility, it is necessary to develop energy hubs dedicated to the fast charging of electric bus batteries with advanced distribution infrastructures on the model of micro-grids. The studied hub topology consist of a fast battery charger, renewable energy generation, energy storage systems, auxiliary loads and a bidirectional interface with the LVAC distribution network. In order to achieve the objectives of a sustainable mobility, such a hub should provide services in terms of support to the grid, efficient use of renewable energy, and energy availability for the users at viable costs. The conception of the Energy Management System (EMS) of such a hub is a perfect use case for the Hardware in the Loop (HIL) design tools. This paper describes the conception and the realization of an emulator of a charging infrastructure energy hub at a downscale of 1:100 in power and the development of the corresponding EMS with the help of Energy Macroscopic Representation (EMR) and advanced HIL.
