RÉSUMÉ / ABSTRACT :
Stand alone hybrid renewable energy systems are more reliable than a system with a single source of energy. However, its design is a crucial issue. In this context, we propose a triple Multi-Objective design, minimizing, simultaneously, Life Cycle Cost (LCC), Embodied Energy (EE) and Loss of Power Supply Probability (LPSP). Optimization has been insured by a dynamic model of the system under Matlab/Simulink and using a controlled elitist genetic algorithm. Results indicate that proposed method, through its multitude Pareto front solutions, will help designers to take into consideration environmental impact of such systems.
