Hybrid Renewable Energy Systems

Multi-generation systems are represented as reliable systems integrated with near-zero energy buildings (NZEBs). In this research, a novel dynamic multi-generation system based on solar and wind energies is analyzed to provide cooling, heating, electricity and freshwater of a residential building. The simulation is conducted under different weather conditions in Khabarovsk, Yakutsk, Yekaterinburg and St. Petersburg cities of Russia from energy, exergy, economic and environmental perspectives for a whole year. The system is equipped with the main components such as flat plate collector (FPC), wind turbine, thermal energy storage (TES), absorption chiller, reverse osmosis (RO), internal combustion engine (ICE) and hydrogen energy storage system (HESS). Combination of TRNSYS, Energy Plus and Engineering Equation Solver (EES) packages is utilized to dynamic simulation. To meet all the demands, a TES equipped with an electrical heater is proposed to meet the rest of the heat demand during lack or absence of radiation. Dynamic calculations of the solar unit show that the FPC can provide 87 % of the building's heat demand in June of Khabarovsk without using TES heater. In addition, the thermodynamic results showed that the maximum energy and exergy efficiencies belong to Khabarovsk at 33.51 % and 27.07 %, respectively. Furthermore, the highest CO2 emission reduction was obtained by useful electricity production and not using natural gas, 20.34 tons and 5 tons for Khabarovsk and Yakutsk, respectively. In conclusion, the economic analysis reported, the best payback period time assuming an interest rate of 0.03 was obtained at 8, 21, 11.2 and 9.8 years for Khabarovsk, Yakutsk, Yekaterinburg and St. Petersburg, respectively.
