CSEM contribution to the DCSMART project is the development and realization of DC distribution demonstration system including local production under the form of a photovoltaic installation and an energy storage system. This demonstration micro-grid is based on an innovative control strategy, for which a patent has been recently filled, allowing to use a single energy storage system to provide different energy services. Tools allowing to perform an economical assessment of the realized solution have also been developed. Current work consist in the commissioning of final parts of the demonstration micro-grid.
