摘要

加沙地带位于巴勒斯坦境内,由于持续的政治不稳定造成长期能源短缺,严重破坏了其电力基础设施。本研究探讨了通过混合并网配置将高水平可再生能源纳入加沙电力系统的可行性。该研究与联合国可持续发展目标7一致,旨在为所有国家提供负担得起的清洁能源,并评估了多种标准,包括经济、环境、能源安全和技术因素。利用多种能源混合优化(HOMER)模拟工具,对各种并网方案进行了评估,以最大限度地降低平准化能源成本(LCOE)、净当前成本(NPC)和温室气体(GHG)排放。研究结果揭示了一个优化的混合能源系统,包括光伏(PV)板、风力涡轮机、生物质能发电机、地热发电机和海浪(水力发电)系统。各能源来源的能源贡献如下:48.5%来自光伏,23.2%来自风能,19.5%来自水电,0.34%来自沼气,0.0233%来自地热,8.44%来自电网购买。值得注意的是,该系统45.6%的电力可以卖回给公用电网。系统峰值容量2190.208 MW,日能耗17874.430 MWh,年油耗由1311 m3降至672 m3。从经济角度来看,该系统的平准化能源成本为0.034美元/千瓦时,净现值成本为28.6亿美元,每年可节省3.58亿美元,投资回收期为6年。在环境方面,该系统减少了52%的二氧化碳排放量,将排放量从703,264吨/年减少到399,872吨/年,突出了其强大的可持续发展潜力。这项研究是首次全面应用HOMER设计一个能够供应加沙整个城市负荷的可再生能源系统,扩大了以前仅限于农村或偏远地区的努力。

Technical-economical-environmental assessment of grid-connected hybrid renewable energy power system for Gaza Strip-palestine
The Gaza Strip, located in Palestine, suffers from chronic energy shortages caused by ongoing political instability, which has severely damaged its electricity infrastructure. This study explores the feasibility of integrating high levels of renewable energy into Gaza’s power system via a hybrid on-grid configuration. The research aligns with UN SDG-7, aiming to provide affordable, clean energy to all nations, and evaluates multiple criteria, including economic, environmental, energy security, and technical factors. Using the Hybrid Optimization of Multiple Energy Resources (HOMER) simulation tool, various grid-connected scenarios were assessed to minimize the Levelized Cost of Energy (LCOE), Net Present Cost (NPC), and greenhouse gas (GHG) emissions. The findings reveal an optimized hybrid energy system comprising photovoltaic (PV) panels, wind turbines, a biomass generator, a geothermal generator, and a sea wave (hydropower) system. The energy contribution from each source is as follows: 48.5 % from PV, 23.2 % from wind, 19.5 % from hydropower, 0.34 % from biogas, 0.0233 % from geothermal, and 8.44 % from grid purchases. Notably, 45.6 % of the system’s electricity can be sold back to the utility grid. The system reaches a peak capacity of 2,190.208 MW and meets a daily consumption of 17,874.430 MWh, while reducing annual fuel consumption from 1,311 m3 to 672 m3. Economically, the system achieves a Levelized Cost of Energy of $0.034/kWh, with a Net Present Cost of $2.86 billion, annual savings of $358 million, and a payback period of 6 years. Environmentally, the system cuts CO2 emissions by 52 %, reducing emissions from 703,264 tonnes/year to 399,872 tonnes/year, highlighting its strong sustainability potential. This study represents the first comprehensive application of HOMER to design a renewable energy system capable of supplying the entire urban load in Gaza, expanding on previous efforts that were limited to rural or remote areas.
