Design and implementation of an experimental DC microgrid for energy self-sufficient isolated sites
Résumé
In the context of climate change, the French law on energy transition for green growth (LTECV) has set a target of electrical autonomy for non-interconnected areas such as Reunion Island by 2030. Despite the significant increasing use of electricity produced by solar panels, the energy losses due to transport and the multiple conversions of sources from direct current (DC) to alternating current (AC) and vice versa, considerably reduce the electrical yield. If we go back to Edison's proposal, a DC electrical architecture has many advantages in the case of local energy production since energy losses in conversions and transport are considerably reduced. In order to quantify precisely with measures potential energy gains of a DC-DC architecture in comparison to a classical DC-AC-DC architecture, currently deployed for isolated sites, the objectives of this project are to deploy a DC measurement bench not backed up by generators and then develop a predictive EMS (Energy Management System) including data from environmental indoor and outdoor sensors and PoE (Power Over Ethernet) drivers for each equipments.
