Modeling and assessment of a novel solar-biomass based distributed multi-generation system

In this research, a distributed multi-generation system combining photovoltaic-thermal collectors with biomass generating units is established in numerical simulation environment. This aims to fulfilling heating demand of single-storey cottage located Xi'an, Northwest China. The feasibility and stepped utilization different levels energy are validated illustrated. order achieve reachable maximum efficiency, key parameters the system, such as collector area, thermal storage capacity, set temperature among other parameters, combined multitude ways, optimal obtained. After running model, throughout season, results show that solar contributes 1698 kWh accounting for nearly 60% total input, while accounts 40% 852.95 kWh, which directly determines stability supply. Once-daily electricity buffer generated by generator holds at 21.67 able meet most load scenarios China, without auxiliary well achieves carbon neutrality goal.
