In many regions, microgrids with photovoltaic (PV) production and electrical storage become a choice adopted by more and more industrial and community energy systems. Microgrid control design is a complex topic, as it has to deal with technical constraints, guarantee and economic optimization on different time scales. CEA-INES has developed a complete multiple-levels controls system architecture for microgrid together with methodology for such controls validation. This paper focuses on operation control short-term development and validation through various steps starting from simulation validation to experimentation. A study case of a microgrid integrating production mixt of photovoltaic and diesel generators production, together with a battery storage with a black-start management will be performed for illustration.
