Abstract

The dependence of the Non-Interconnected Islands on diesel power stations increases the cost of producing electricity in comparison to the mainland. This study focuses on the green energy transition of Interconnected Islands, and Anafi was selected as a characteristic case. The average cost of electricity production from thermal units in Anafi was estimated to be 539 €/MWh with a peak load of 0.55 MW. Two different green energy transition scenarios are proposed for Anafi that include the addition of PV panels plus a wind turbine (scenario 1) or PV panels plus a battery (scenario 2) that would operate along the conventional diesel engines and utilized the software RETScreen program for the design and the analysis of these two proposed hybrid systems. In scenario 1, the renewable systems produced 2793 MWh, while in scenario 2 this value was simulated to be 995.51 MWh. In both proposed scenarios there is a significant penetration from Renewable Energy Sources from 68.2% (scenario 2) to 90.3% (scenario 1). In addition, in both cases there is a significant reduction in carbon dioxide emissions from 80%–95% in comparison to the baseline case which produces 2543 tons of CO2 annually. The cost of the proposed installations has been calculated to be 5.2 m € and 5.6 m € for scenarios 1 and 2, while the net present value (NPV) of the project becomes positive from the sixth year and the eleventh year respectively. The earnings of a green transition project of this nature can be allocated for the maintenance of the island's own project, as well as for the financing of new similar projects. on other islands. The expected result of this work is the proposal of a system that will largely cover the energy needs of the island, reduce the cost of production per kilowatt hour and will contribute to the green energy transition of the other Non-Interconnected Islands.
在孤立电网中增加可再生能源渗透的风能混合系统:Anafi(希腊)案例研究
与大陆相比,非互联岛屿对柴油发电站的依赖增加了发电成本。本研究以互联岛屿绿色能源转型为研究对象,选取阿纳菲作为典型案例。Anafi热电机组发电的平均成本估计为539欧元/兆瓦时,峰值负荷为0.55兆瓦。Anafi提出了两种不同的绿色能源转型方案,包括增加光伏板加风力涡轮机(方案1)或光伏板加电池(方案2),它们将沿着传统柴油发动机运行,并利用RETScreen软件程序设计和分析这两种拟议的混合动力系统。在场景1中,可再生能源系统产生2793兆瓦时,而在场景2中,该值被模拟为995.51兆瓦时。在这两种方案中,可再生能源的渗透率都从68.2%(方案2)提高到90.3%(方案1)。此外,与每年产生2543吨二氧化碳的基准方案相比,在这两种方案中,二氧化碳排放量都从80%-95%显著减少。方案1和方案2的拟议安装成本分别为520万欧元和560万欧元,而项目的净现值(NPV)分别从第6年和第11年变为正值。这种性质的绿色过渡项目的收益可以分配用于维护岛屿自己的项目,以及为新的类似项目提供资金。在其他岛屿上。这项工作的预期结果是提出一个系统,该系统将在很大程度上满足该岛的能源需求,降低每千瓦时的生产成本,并将有助于其他非互联岛屿的绿色能源转型。
