Design and tri-objective optimization of an energy plant integrated with near-zero energy building including energy storage: An application of dynamic simulation

摘要

Transient performance assessment and techno-economic analysis are presented for a novel smart energy system driven by hybrid solar-Hydrogen energies. The proposed system is developed to provide power, heating, and cooling demands for a two-story building as the case study. In detail, the system is composed of photovoltaic thermal panels, fuel cells, thermal energy storage, solar collector, and a small-scale Organic Rankin Cycle. To generate the heating and cooling of a heat pump, an absorption chiller is occupied. The system is analyzed from technical and economic standpoints as well as environmental considerations. To find the best solution point for the system, a tri-objective optimization as a cutting-edge method to optimize all the mentioned indexes is conducted. The system is grid-connected, and the excess power could be sold to the power grid. The results show that the 19.92 kWh power can be sold to the grid, and the heating and cooling load demand are amended. Moreover, at the optimized point, the plant can accomplish the minimum cost and emission of 0.37 Ton/MWh and 8.46 $/GJ, respectively, while the yearly efficiency reaches 37.28%. In conclusion, this study has highlighted the potential of solar-driven micro-CCHP systems based on advanced technologies for residential applications.
