Nowadays, the exploitation of renewable energy sources is the most effective way to force a drastic abatement in greenhouse gas emissions. This consideration is even more strategic when envisaging the green supply of large power industrial loads, which are indeed responsible for an important quota of CO2 production. To foster the sustainability revolution in the industrial sector, an appealing option is to combine battery storage systems and photovoltaic power plant into a DC microgrid architecture. Such a power system is characterized by the presence of multiple power electronics converters, enabling its full controllability. The converters can be coordinated in order to direct the green energy towards the industrial factories. The paper wants to discuss about the smart DC power routing to support the energy demand of an industrial cluster.
