Abstract

This research proposes an optimum grid-connected photovoltaic (PV) installation to meet the energy requirements of residential buildings in Saudi Arabia (KSA). Load profile data is used to establish a realistic electricity demand pattern. Sensitivity analyses are performed for 19 cities, varying the renewable fraction from 0% to 100%, to determine the minimum renewable energy fraction required to achieve competitive Cost of Energy (COE) values. The results show that increasing the renewable fraction reduces the COE of PV systems but leads to higher capital costs and Net Present Cost (NPC). The study also emphasizes the importance of considering CO₂ emissions reduction achievable through PV system integration. Based on tradeoffs between renewable fraction and NPC, Hail, Sakaka, and Jeddah rank as the top three sites, balancing economic viability and renewable energy utilization. The outcomes provide valuable insights for decision-making and promote sustainable energy transition in KSA. Grid-connected PV systems bring social benefits, including job creation, improved living conditions, reduced emissions, enhanced energy security, and increased public awareness. This research contributes to understanding the renewable energy landscape in KSA and provides a methodology based on a multi-criteria assessment, using a search space algorithm to minimize the NPC or identify optimal PV installation sites that support the decisions of energy policymakers.

沙特阿拉伯建筑部门并网太阳能光伏系统的技术经济评估和优化

本研究提出了一种最佳的并网光伏（PV）装置，以满足沙特阿拉伯（KSA）住宅建筑的能源需求。负荷分布数据被用来建立一个真实的电力需求模式。对19个城市的可再生能源比例从0%到100%进行了敏感性分析，以确定实现有竞争力的能源成本（COE）值所需的最低可再生能源比例。结果表明，增加可再生能源比例会降低光伏系统的COE，但会导致更高的资本成本和净当前成本（NPC）。该研究还强调了考虑通过光伏系统集成实现二氧化碳减排的重要性。基于可再生能源比例和NPC之间的权衡，Hail、Sakaka和吉达在经济可行性和可再生能源利用之间取得了平衡，排名前三。研究结果为沙特阿拉伯的决策和促进可持续能源转型提供了有价值的见解。并网光伏系统带来了社会效益，包括创造就业机会、改善生活条件、减少排放、加强能源安全以及提高公众意识。这项研究有助于了解沙特阿拉伯的可再生能源格局，并提供了一种基于多标准评估的方法，使用搜索空间算法来最小化NPC或确定支持能源政策制定者决策的最佳光伏安装地点。

期刊介绍： Utilities Policy is deliberately international, interdisciplinary, and intersectoral. Articles address utility trends and issues in both developed and developing economies. Authors and reviewers come from various disciplines, including economics, political science, sociology, law, finance, accounting, management, and engineering. Areas of focus include the utility and network industries providing essential electricity, natural gas, water and wastewater, solid waste, communications, broadband, postal, and public transportation services. Utilities Policy invites submissions that apply various quantitative and qualitative methods. Contributions are welcome from both established and emerging scholars as well as accomplished practitioners. Interdisciplinary, comparative, and applied works are encouraged. Submissions to the journal should have a clear focus on governance, performance, and/or analysis of public utilities with an aim toward informing the policymaking process and providing recommendations as appropriate. Relevant topics and issues include but are not limited to industry structures and ownership, market design and dynamics, economic development, resource planning, system modeling, accounting and finance, infrastructure investment, supply and demand efficiency, strategic management and productivity, network operations and integration, supply chains, adaptation and flexibility, service-quality standards, benchmarking and metrics, benefit-cost analysis, behavior and incentives, pricing and demand response, economic and environmental regulation, regulatory performance and impact, restructuring and deregulation, and policy institutions.
