This article proposes a unified solution to address the energy issues in net-zero energy building (ZEB), as a new contribution to earlier studies. The multicarrier energy system, including hydro-wind-solar-hydrogen-methane-carbon dioxide-thermal energies is integrated and modeled in ZEB. The electrical sector is supplied by hydro-wind-solar, combined heat and power (CHP), and pumped hydro storage (PHS). The thermal sector is supplied by CHP, thermal boiler, and electric heating. The hydrogen storage system and Methanation process operate as the interface energy carriers between the electrical and thermal sectors. The carbon dioxide (CO2) of the ZEB is captured and fed into the Methanation process. The purpose is minimizing the released CO2 to the atmosphere while all the electrical-thermal load demands are successfully supplied considering events and disruptions. The model improves simultaneously the energy resilience and minimizes the environmental pollutions. The results demonstrate that the developed model reduces the CO2 pollution by about 33 451 kg per year. The model is a resilient energy system that can handle all failures of components. The model can efficiently handle 26% increment in the electrical loads and 110% increment in the thermal loads.

水力、风能、太阳能和氢能等多载体能源系统的零能源建设


本文提出了一种统一的解决方案来解决净零能耗建筑（ZEB）中的能源问题，作为对早期研究的新贡献。多载体能源系统，包括水力-风能-太阳能-氢气-甲烷-二氧化碳-热能在ZEB中进行集成和建模。电力部门由水力-风能-太阳能、热电联产（CHP）和抽水蓄能（PHS）供电。热力部门由热电联产、热力锅炉和电加热提供。储氢系统和甲烷化过程作为电力和热力部门之间的界面能量载体。 ZEB 的二氧化碳 (CO2) 被捕获并送入甲烷化过程。目的是最大限度地减少释放到大气中的二氧化碳，同时考虑到事件和中断，成功满足所有电热负载需求。该模型同时提高了能源弹性并最大限度地减少了环境污染。结果表明，所开发的模型每年减少二氧化碳污染约 33 451 千克。该模型是一个弹性能源系统，可以处理组件的所有故障。该模型可以有效处理 26% 的电负载增量和 110% 的热负载增量。
