This paper proposes an efficient external energy maximization strategy (EEMS) for a residential micro grid system (MGS). The system sources decomposed into three parts, a photovoltaic (PV) array being a green energy source, an AC grid and a hybrid energy storage system (HESS) (a battery (BT) and supercapacitor (SC)). The proposed strategy aimed at minimizing the grid energy consumption and improve the overall system efficiency by maximizing the BT and SC energy demands within their effective operating limits during the no PV electricity production. This enhance the efficiency of the energy management system during load profile variations. The performance of the proposed EEMS is compared with the PI controller and the equivalent consumption minimization strategy (ECMS) through simulations. A simulation model are developed using Matlab/Simulink to validate all performances.
