Abstract

This paper presents a study aimed at evaluating a hybrid renewable energy system connected to the utility grid considering an average load demand of 15000 kW/day and a peak load of almost 2395.3 kW. To assess the renewable energy resources potential and perform the techno-economic analyses, HOMER software is used. In this study, Renewable Resources Atlas meteorological data were collected. These data are under the development of King Abdullah City of Atomic and Renewable Energy (KACARE). The Riyadh city located in Saudi Arabia has been selected to apply this study. Net present cost (NPC) , levelized cost of energy (LCOE), and system environmental impacts were investigated .The simulation results show that the proposed system performed reasonably and reduce the amount of annual CO2 emissions. However, lacking enough RE resources may add more cost on the system rather than work effectively. Therefore, in this study using wind energy source with the grid system is the best option ,economically. Such system is applicable in the region and around the world for any place has similar conditions. reduction of energy costs and some greenhouse gasses are main contributors of this study.

光伏/风能混合发电系统并网技术经济分析

本文提出了一项研究，旨在评估连接到公用电网的混合可再生能源系统，考虑平均负荷需求为15000千瓦/天，峰值负荷接近2395.3千瓦。为了评估可再生能源的潜力并进行技术经济分析，使用了HOMER软件。本研究收集了可再生资源地图集气象数据。这些数据是由阿卜杜拉国王原子能和可再生能源城(KACARE)开发的。位于沙特阿拉伯的利雅得市被选中应用这项研究。对净现值成本(NPC)、平准化能源成本(LCOE)和系统环境影响进行了研究。仿真结果表明，所提出的系统运行合理，减少了年二氧化碳排放量。然而，缺乏足够的可再生资源可能会增加系统的成本，而不是有效地工作。因此，在本研究中，利用风能与并网系统是经济上的最佳选择。这种制度适用于本地区和世界各地，因为任何地方都有类似的条件。能源成本的降低和一些温室气体的排放是本研究的主要贡献者。
