With the environmental issues and the new ecological considerations, one of the challenges is the creation of sustainable electric grid to supply the demand. With this context, we observe the deployment of decentralized Low Voltage DC Microgrids (LVDC MG) in building, with high penetration of Renewable Energy Sources (RES) and Energy Storage Systems (ESS). The aim of this PhD thesis is to contribute in this field by designing an LVDC MG in the ADREAM Building integrated PV (BiPV), at LAAS-CNRS, TOULOUSE. The main difficulties are to consider the ESS behavior and aging mechanisms with a global system approach in order to proposed a sizing method and an energy management strategy optimized and simple to implemented for electrical research community.

Scientific goals
- To study the impacts of BiPV production and DC building loads power profiles on ESS behavior and lifetime
- To propose a methodology, with a systemic approach, to size the PV and the ESS in building microgrids context
- To compare multiple ESS behavior and lifetime modeling approaches dedicated to optimal sizing and energy management strategy
- To design an LVDC MG to supply the ADREAM BiPV lightning network and compare the measurements and the different batteries models used
- To compare the performances of Lead acid batteries and Lithium-ions batteries in our case study
