Popis: International audience; This paper presents the modelling and energy management of a grid connected PV system associatedwith storage. Within the economic, energetic and environmental context, objective of the system is to ensure loadssupply at the least cost by optimising the use of solar power. Therefore, due to the complicated operating patterns, anenergy management system which decides on energy flow for any moment is necessary. First, we present the systemstudied. Based on an AC bus typology, we consider all the energy flow possibilities. A model of the system ispresented with an innovate algorithm for the estimation of batteries state of charge (SOC). Energy management hasbeen done with a deterministic algorithm. At each step size, the algorithm finds the energy flow pattern whichensures loads supply at the least cost, taking into account availability of PV power, batteries SOC, loads demand andinstantaneous electricity grid prices.
