Mixed-integer algorithm for optimal dispatch of integrated PV-storage systems

The exploitation of combined photovoltaic plants and storage systems is nowadays assuming growing importance due to the technical, energetic, environmental and economical benefits which can derive from an optimal integration. In this paper a mixed-integer algorithm for optimal dispatch of a lithium-ions storage system, based on the day ahead PV forecasting, is developed within an existing Distribution Management System, which operates on the low voltage Microgrid at University of Genova. The optimization object is the maximization of the Microgrid production according to the requested active power profile, which can be defined by the operator. The procedure has been validated by field results with particular attention to the storage efficiency, that has been modeled with additional constraints.
