Integration of CCHP and solar plants for household applications a multiobjective optimization model

In the last years the household sector has become the main energy consumer. Among the actions for a more rational and more sustainable primary energy exploitation, cogeneration and trigeneration, eventually integrated with technologies based on renewable energy sources, are assuming a great role in the sector. The optimization of the system components and the overall plant reflects the choice of costs or CO₂ emissions minimization leading to several solutions in a multiobjective context. This work, through a mathematical model, shows that different integration levels among the components play a crucial role on the efficiency of the system as a whole, even if the single component does not operate in its own best conditions.
