Abstract: In this paper the authors investigate the interest in hybridisation of autonomous renewable multi-source systems under economic environmental and technical indicators of a hybrid photovoltaic-wind system with battery storage of a residential house. A parametric sensitivity algorithm is developed to find the best compromise between four objectives: embodied energy, GHG emissions, life cycle cost and loss of power probability. During a life cycle period of 25 years, nine models of embodied energy, GHG emission and life cycle cost are developed. A dynamic simulator and its power management is developed under annual data of weather conditions and electric load data (residential house) for one year with a sampling step of half an hour. As results, it is found that the hybrid WT/Battery is the environmentally better choice while the hybrid PV/Battery is the economically better choice. But, the hybrid PV/WT/Battery system is designed to meet both the economic and environmental requirements.

Keywords: hybrid systems; dynamic simulator; life cycle assessment; parametric sensitivity; environmental impacts; hybridisation.
