COVID-19 has affected energy consumption and production pattern in various sectors in both rural and urban areas. Consequently, energy demand has increased. Therefore, most health care centers report a shortage of energy, particularly during the summer seasons. Therefore, integrating renewable energies into hospitals is a promising method that can generate electricity demand reliably and emits less CO2. In this research paper, a hybrid renewable energy system (HRES) with hydrogen energy storage is simulated to cover the energy demand of sections and wards of a hospital that dealt with COVID-19 patients. Produced Oxygen from the hydrogen storage system is captured and stored in medical capsules to generate the oxygen demand for the patients. Results indicate that 29.64% of the annual consumed energy is utilized in COVID-19 sections. Afterward, modeled system has been optimized with a neural network-genetic algorithm to compute the optimum amount of the demand power from the grid, CO2 emission, oxygen capsules, and cost rate. Results determine that by having 976 PV panels, 179 kW fuel cell, and 171.2 kW electrolyzer, annual CO2 emission is 315.8 tons and 67,833 filled medical oxygen capsules can be achieved. The cost rate and demand electricity from the grid for the described system configuration are 469.07 MWh/year and 18.930 EUR/hr, respectively.
新冠疫情影响了农村和城市各部门的能源消耗及生产模式。因此,能源需求增加。所以,多数医疗保健中心报告能源短缺,尤其是在夏季。因此,将可再生能源整合到医院是一种有前景的方法,它能可靠地满足电力需求且二氧化碳排放量更少。在本研究论文中,对一个带有氢能存储的混合可再生能源系统(HRES)进行了模拟,以满足一家收治新冠患者医院的科室和病房的能源需求。储氢系统产生的氧气被收集并存储在医用胶囊中,以满足患者的氧气需求。结果表明,新冠科室消耗了年度总能耗的29.64%。之后,使用神经网络 - 遗传算法对该模型系统进行了优化,以计算来自电网的最佳需求电量、二氧化碳排放量、氧气胶囊数量和成本率。结果确定,配备976块光伏板、179千瓦燃料电池和171.2千瓦电解槽时,年度二氧化碳排放量为315.8吨,可制备67,833个装满氧气的医用胶囊。对于上述系统配置,成本率和来自电网的需求电量分别为469.07兆瓦时/年和18.930欧元/小时。
