Abstract

This paper proposed a standalone solar/wind/micro-hydro hybrid power generation system to electrify Ethiopian remote areas that are far from the national utility grid. The aim is that it will lead to the development of renewable energy sources, using a hybrid optimization model for energy renewables (HOMER) as an optimization and sensitivity tool and MATLAB as a design tool. The system uses 100% renewable energy. This system incorporated solar photo-voltaic (PV), wind turbines, micro-hydro systems, and battery systems. The net present cost of the system is $4,377,731, incorporating capital depreciation and levelized operation and maintenance costs. During the hybrid energy system’s lifetime, the cost of a grid extension power supply is $22.185 million, which is nearly $17,808,000 more than the cost of the proposed standalone system. So, developing solar/wind/micro-hydro hybrid power generation will save $17,808,000 versus extending the national utility grid. As a result of a thorough examination of renewable energy resources, standalone solar, wind, and micro-hydro hybrid power generation is a technically and economically viable option for the case study area of Maji town.

偏远地区独立混合发电系统的可行性分析与开发——以埃塞俄比亚农村地区为例

本文提出了一个独立的太阳能/风能/微水力混合发电系统，为远离国家公用电网的埃塞俄比亚偏远地区供电。以可再生能源混合优化模型(HOMER)为优化和灵敏度工具，以MATLAB为设计工具，引领可再生能源的发展。该系统100%使用可再生能源。该系统包括太阳能光伏(PV)、风力涡轮机、微型水力发电系统和电池系统。该系统目前的净成本为4 377 731美元，其中包括资本折旧和平摊的操作和维修费用。在混合能源系统的生命周期内，电网扩展供电的成本为2218.5万美元，比拟议的独立系统的成本高出近17808万美元。因此，与扩大国家公用电网相比，开发太阳能/风能/微型水力混合发电将节省17,808,000美元。经过对可再生能源资源的全面考察，独立的太阳能、风能和微型水力混合发电在技术和经济上都是马集镇案例研究区域可行的选择。
