Abstract: Stand-alone renewable systems comprise one of the most promising electrification solutions for covering the demand of remote consumers. However, the high dependency on weather state and the nonlinearity of the system cause a variation in voltage, power and frequency. This study presents a nonlinear controller to attain maximum performance for both sources, then a smart strategy to control the power flow between the hybrid power system and the batteries in order to satisfy the load requirements while keeping the state of charge within secure limits is introduced. To accomplish efficient energy management, we combine two powerful renewable energies solar and wind, batteries were also used to store the excess of energy or to supply the system with the required energy. The proposed standalone is tested with variable solar irradiation, temperature and wind speed and the results presented affirm the efficiency of the proposed control.
