Abstract

This paper presents an optimized design of an off-grid microgrid capable of fulfilling the year-round power demands of a remote area in Egypt. The proposed system combines photovoltaic, Wind Turbine (WT), backed by batteries, and biomass technologies to ensure consistency and eco-friendliness with fewer pollutants. A comprehensive analysis using HOMER Pro software was utilized to identify the optimum design, considering the energy demand, renewable resource availability, and net present cost (NPC) of the system. The results show that the optimal design includes a solar Photovoltaic (PV) system, WT, backed up by batteries, and a stand-by biomass generator (BIOMG). The design can significantly decrease reliance on conventional energy sources and promote the growth of renewable energy in the region. This study is considered the cheapest model in this configuration (PV, WT, Batteries, BIOMG) if compared to previous studies in the same location through a total NPC of USD3,483,519.00and the best cost of energy (COE) of USD0.118. Additionally, the proposed system decreases emissions that contribute to global warming with a GHG of 28,516 tons/year. A sensitivity analysis of the uncertainty of renewable resources and economics has been conducted. The sensitivity analysis illustrates the variety of results.

埃及西部沙漠生物质备份混合可再生能源系统的最佳规模

本文提出了一种能够满足埃及偏远地区全年电力需求的离网微电网的优化设计。拟议的系统结合了光伏、风力涡轮机（WT）、电池和生物质能技术，以确保一致性和生态友好性，减少污染物。综合考虑能源需求、可再生资源可用性和系统净当前成本（NPC），利用HOMER Pro软件进行综合分析，确定最佳设计方案。结果表明，优化设计包括一个太阳能光伏（PV）系统，WT，由电池备份，和一个备用生物质发电机（BIOMG）。该设计可以显著减少对传统能源的依赖，促进该地区可再生能源的发展。如果与同一地点的先前研究相比，该研究被认为是该配置（PV， WT, Batteries， BIOMG）中最便宜的模型，总NPC为3,483,519.00美元，最佳能源成本（COE）为0.118美元。此外，该系统还减少了导致全球变暖的温室气体排放量，每年减少28,516吨。对再生资源的不确定性和经济性进行了敏感性分析。敏感性分析说明了结果的多样性。
