Several oil-importing countries tend to utilize renewables as alternatives to traditional energy sources. This is to replace conventional fossil fuel plants with clean, economical, and reliable energy resources. In this paper, all possible on-grid renewable energy systems with different design scenarios are investigated to satisfy the load demand of Al-Mastaba city, Jordan. These grid-connected cases include solar photovoltaic (PV) only, wind only, hybrid PV/wind, PV/pumped hydro storage (PHS), wind/PHS, and hybrid PV/wind/PHS systems. In each scenario, the optimal sizing and energy management strategy are achieved using flow direction optimization algorithm. This is done by minimizing the grid usage factor (GUF). The decision variables include the number of PV panels, the number of wind turbines, and/or the height of upper reservoir (UR) of the PHS facility (hhydro). The input hourly measured data for systems' components were brought from formal institutions to get realistic and future real-life recommendations. Results showed that hybrid PV/wind/PHS (Scenario 6) has the best design. It has the lowest GUF of 0.59%. It comprises of 12,692 solar panels, 28 wind turbines, and 106.98m as hhydro of the UR. The uncertainty analysis on input measured data is implemented to test the system's robustness. It is noticed that the 6th scenario released an amount of CO2 of 122.29 t/year and the corresponding renewable storage factor is 63.72% with 0.042 $/kWh as the lowest value of levelized cost of energy. The methodology of this paper is highly recommended anywhere to reduce grid purchases and make it dispensable by adopting renewable retrofitting systems.

不同设计策略的大规模并网可再生能源系统优化配置

一些石油进口国倾向于利用可再生能源作为传统能源的替代品。这是用清洁、经济和可靠的能源资源取代传统的化石燃料工厂。在本文中,研究了具有不同设计方案的所有可能的并网可再生能源系统,以满足约旦 Al-Mastaba 市的负荷需求。这些并网案例包括仅太阳能光伏 (PV)、仅风能、混合光伏/风能、光伏/抽水蓄能 (PHS)、风能/PHS 和混合光伏/风能/PHS 系统。在每个场景中,最佳尺寸和能量管理策略都是使用流向优化算法实现的。这是通过最小化网格使用因子 (GUF) 来完成的。决策变量包括光伏电池板的数量、风力涡轮机的数量、h水电)。系统组件的输入每小时测量数据来自正规机构,以获得切合实际和未来现实生活的建议。结果表明,混合光伏/风能/PHS(方案 6)具有最佳设计。它的 GUF 最低,为 0.59%。它由 12,692 块太阳能电池板、 28台风力涡轮机和 106.98 米的UR水电组成。对输入的测量数据进行不确定性分析,以测试系统的鲁棒性。值得注意的是,第 6 个场景释放了一定数量的C2个为 122.29 吨/年,相应的可再生存储系数为 63.72%,其中 0.042 美元/千瓦时是能源平准化成本的最低值。强烈建议在任何地方使用本文的方法来减少电网采购,并通过采用可再生改造系统使其变得可有可无。
