论文摘要
最近的全球事件强调了可靠的能源供应的重要性。提高能源供应安全性的一种方法是通过分散的离网性可再生能源系统，为此研究了越来越多的案例研究。这篇综述给出了这些自主能源系统的电平（LCOE）的全球概述，从0.03 \ $ _ {2021}/kWh到全球范围内的1.00 \ $ _ {2021}/kWh。在2016年至2021年间，100％可再生能源系统的平均LCOE从0.54 \ $ _ {2021}/kWh降至0.29 \ $ _ {2021}/kWh，大概是由于可再生能源和存储技术的成本降低。此外，我们确定并讨论了LCOE经常被高估或在文献中被低估的七个关键原因，以及将来如何预防它。我们的概述可以用于验证离网系统上的发现，以评估这些系统可以部署的位置以及成本如何发展。
Recent global events emphasize the importance of a reliable energy supply. One way to increase energy supply security is through decentralized off-grid renewable energy systems, for which a growing number of case studies are researched. This review gives a global overview of the levelized cost of electricity (LCOE) for these autonomous energy systems, which range from 0.03 \$_{2021}/kWh to over 1.00 \$_{2021}/kWh worldwide. The average LCOEs for 100% renewable energy systems have decreased by 9% annually between 2016 and 2021 from 0.54 \$_{2021}/kWh to 0.29 \$_{2021}/kWh, presumably due to cost reductions in renewable energy and storage technologies. Furthermore, we identify and discuss seven key reasons why LCOEs are frequently overestimated or underestimated in literature, and how this can be prevented in the future. Our overview can be employed to verify findings on off-grid systems, to assess where these systems might be deployed and how costs evolve.
