Supplying the ever-increasing energy demand both economically viable and environmentally friendly is among the primary challenges of the present century. In this regard, the current research suggests a resilient smart hybrid renewable energy system to supply the electricity and heat demand of Eram Campus, Shiraz University. Pre-assessments are carried out to realize the energy demand, primary energy potentials, and geographical constraints of the Campus. In the present work, simulations, optimizations, and sensitivity analyses are performed to explore the feasibility of utilizing a unique integrated energy system to meet the load demand of the case study. The results indicate that the suggested energy system consists of a micro gas turbine with combined heat and power module, thermal boilers, converters, photovoltaic panels, pumped hydro storage units, and a predictive controller. To make use of the proposed power plant, $15 M is needed for initial capital cost. Levelized cost of electricity and net present cost of the system are 0.09$/kWh and $42.5 M, respectively. Based on the findings, using the suggested energy system reduces the annual carbon dioxide production of the Campus by 8000 megatonnes compared when using the national energy grid. Furthermore, the calculations reflected that the impacts of variations in financial parameters, carbon penalty, energy demand increase, and allowable capacity shortage on the characteristics of the energy system are considerable. In the most economical strategy, the capacities of the gas turbine, thermal boiler, photovoltaic panel, converter, and pumped hydro storage should be 2650 kW, 17 MW, 13754 kW, 4995 kW, and 70 units, respectively, to meet the increase of 50% in energy demand. By reducing the energy consumption in specific time steps by 1% of the total load, the net present cost and levelized cost of electricity significantly decline by 6% and 15%, respectively. The results of this study concern whatever the policymakers need to ensure the feasibility of implementing a smart integrated energy system to reach the first renewable-powered University Campus in Iran.

为设拉子大学 Eram 校区供电和供热需求的智能混合可再生能源系统的可行性研究;仿真、优化和灵敏度分析

供应经济上可行且环境友好的不断增长的能源需求是本世纪的主要挑战之一。在这方面,目前的研究提出了一种弹性的智能混合可再生能源系统来满足设拉子大学 Eram 校区的电力和热力需求。进行预评估以了解校园的能源需求、一次能源潜力和地理限制。在目前的工作中,进行了模拟、优化和敏感性分析,以探索利用独特的综合能源系统来满足案例研究的负载需求的可行性。结果表明,建议的能源系统由一个带有热电联产模块的微型燃气轮机、热锅炉、转换器、光伏电池板、抽水蓄能装置和预测控制器。为了使用拟建的发电厂,初始资本成本需要 1500 万美元。该系统的平准化电力成本和净现成本分别为 0.09 美元/千瓦时和 4250 万美元。根据调查结果,与使用国家能源网相比,使用建议的能源系统可将校园每年的二氧化碳产量减少 8000 兆吨。此外,计算还反映了财务参数变化、碳惩罚、能源需求增加和允许容量短缺对能源系统特性的影响是相当大的。在最经济的策略中,燃气轮机、热力锅炉、光伏板、变流器和抽水蓄能的容量应为2650千瓦、17兆瓦、13754千瓦、4995千瓦和70台,分别满足增长50%的能源需求。通过将特定时间步长的能耗降低占总负荷的 1%,电力的净现值和平准化成本分别显着下降 6% 和 15%。这项研究的结果涉及决策者需要确保实施智能综合能源系统以到达伊朗第一个可再生能源大学校园的可行性。
