摘要

近年来,太阳能变得越来越重要。装机容量多年来一直在增加,今天太阳能是可再生能源贡献的重要组成部分。光伏板的缺点之一是冷却过程。面板容易过热,从而导致效率降低。缓解这个问题的方法之一是在海上安装光伏板,在那里冷却效率更高,从而增加发电量。由于文献中缺乏深入分析研究海上光伏板传热的数值模型,本工作提出了一个计算流体动力学模型来分析海上光伏板的热性能。采用数值模型对传热过程进行了表征。该模型通过陆上面板设置的实验数据进行了验证,其中测量了太阳辐射、入口空气温度和太阳能电池温度等关键参数。对陆上和海上设施进行了比较。该模型显示,海上条件下太阳能电池的平均温度为39.11°C,而陆上电池板的平均温度为45.5°C。经过一天的分析,平均效率从10.7%提高到11.2%。该研究还强调了水温在影响光伏板热性能方面的关键作用。研究发现,水温升高对海洋生态系统的潜在影响可以忽略不计,这支持了海上光伏系统的可持续性。这些结果证明了海上光伏系统相对于传统陆上光伏系统的优势,有助于推动可持续能源解决方案的发展。

CFD model of the heat transfer processes in an offshore photovoltaic panel

CFD model of the heat transfer processes in an offshore photovoltaic panel

Solar energy has become increasingly important in recent years. The installed capacity has increased over the years, and today solar energy represents a significant part of the renewable energy contribution. One of the handicaps of photovoltaic panels is the cooling process. The panels are susceptible to overheating, which leads to a reduction in efficiency. One of the ways to mitigate this problem is to install the photovoltaic panels offshore, where cooling is more efficient, thus increasing power generation. Due to the lack of in-depth analysis of numerical models for studying heat transfer in offshore photovoltaic panels in the literature, this work proposes a computational fluid dynamics model to analyse the thermal performance of an offshore photovoltaic panel. The numerical model was used to characterize the heat transfer processes. The model was validated with experimental data from an onshore panel setup, where key parameters such as solar radiation, inlet air temperature, and solar cell temperature were measured. A comparison between onshore and offshore installations was made. The model showed that the average solar cell temperature in offshore conditions is 39.11°C, compared to 45.5°C for onshore panels. Over a day analysed, the average efficiency improved from, 10.7% to 11.2%. The research also highlighted the critical role of water temperature in affecting the thermal performance of PV panels. The potential impact on the marine ecosystem due to increases in water temperature was found to be negligible, supporting the sustainability of offshore PV systems. These results demonstrate the advantages of offshore photovoltaic systems over traditional onshore ones, contributing to the advancement of sustainable energy solutions.

期刊介绍: IET Renewable Power Generation (RPG) brings together the topics of renewable energy technology, power generation and systems integration, with techno-economic issues. All renewable energy generation technologies are within the scope of the journal. Specific technology areas covered by the journal include: Wind power technology and systems Photovoltaics Solar thermal power generation Geothermal energy Fuel cells Wave power Marine current energy Biomass conversion and power generation What differentiates RPG from technology specific journals is a concern with power generation and how the characteristics of the different renewable sources affect electrical power conversion, including power electronic design, integration in to power systems, and techno-economic issues. Other technologies that have a direct role in sustainable power generation such as fuel cells and energy storage are also covered, as are system control approaches such as demand side management, which facilitate the integration of renewable sources into power systems, both large and small. The journal provides a forum for the presentation of new research, development and applications of renewable power generation. Demonstrations and experimentally based research are particularly valued, and modelling studies should as far as possible be validated so as to give confidence that the models are representative of real-world behavior. Research that explores issues where the characteristics of the renewable energy source and their control impact on the power conversion is welcome. Papers covering the wider areas of power system control and operation, including scheduling and protection that are central to the challenge of renewable power integration are particularly encouraged. The journal is technology focused covering design, demonstration, modelling and analysis, but papers covering techno-economic issues are also of interest. Papers presenting new modelling and theory are welcome but this must be relevant to real power systems and power generation. Most papers are expected to include significant novelty of approach or application that has general applicability, and where appropriate include experimental results. Critical reviews of relevant topics are also invited and these would be expected to be comprehensive and fully referenced. Current Special Issue.
