本文基于实际的发电侧能源审计、季节性可再生能源资源可用性与负荷概况的评估以及技术经济分析，为度假岛提出了多种混合可再生能源系统的最佳组合。本文选择刁曼岛作为研究对象，是因为刁曼岛代表了南海众多度假岛屿的典型能源需求。该岛主要依靠柴油发电。因此，发电公司面临着柴油市场价格的波动和高昂的运营和维护成本。此外，柴油发电厂可能带来燃料泄漏和环境退化的风险。因此，为了减轻对柴油燃料的依赖，提出了混合柴油和可再生能源的最佳组合。该研究从实际的发电侧审计开始，包括负荷分布、季节性负荷概况和负荷类型，以及对当地发展规划的分析。随后，对太阳能、风能和水力等现有可再生资源潜力进行了调查，其中包括收集和分析气象数据。最后，利用HOMER软件对不同组合的混合能源系统进行技术经济分析。分析结果包括混合动力系统的最优配置、混合动力系统的成本、燃油节约和二氧化碳减排。
This paper proposes multiple optimal combinations of hybrid renewable energy systems for a resort island based on actual generation-side energy auditing, assessment of seasonal renewable energy resources availability versus load profiles, and techno-economic analyses. Tioman Island is selected for this study as it represents the typical energy demands of many resort islands in the South China Sea. The island depends primarily on diesel-fuel for electricity generation. As a result, the generating company is exposed to diesel fuel volatile market prices and high operation and maintenance costs. Moreover, the diesel power plant poses possible risk of fuel spills and environmental degradation. Hence, to mitigate the diesel fuel dependence, an optimal combination of hybrid diesel and renewable energy is proposed. The study starts with an actual generation-side auditing, which includes distribution of loads, seasonal load profiles, and types of loads as well as an analysis of local development planning. Subsequently, surveys of available renewable resource potentials such as solar, wind, and hydro have been conducted that involved collection and analysis of meteorological data. Finally, HOMER software was used to perform techno-economic analyses for different combinations of hybrid energy system. Results of the analyses include the optimal hybrid system configurations, cost of the hybrid system, fuel saving, and CO2 emission reduction.
