摘要

风力发电作为一种前景广阔的可再生能源,有望为人类的未来做出巨大贡献。然而,风力固有的高变异性是阻碍稳定发电的一个挑战。为了将风能作为主要能源加以利用,有人提出了与聚合物电解质膜电解水(PEMWE)系统集成的建议。然而,众所周知,PEMWE 在输入功率模式变化较大时会出现性能退化。这给其商业化带来了挑战。这就需要在设备生产过程中进行各种风力波动的压力测试。本研究调查了具有代表性的风力波动模式,以便在压力测试过程中使用这些模式。我们采用了数据挖掘技术,包括摆动门算法和均值聚类,通过分析间隔为 10 秒的风力发电数据来识别这些模式。因此,我们提出了五个最具代表性的风力发电斜坡。这项研究为风力发电昂贵设备的开发过程提供了实用指南,从而促进了风力发电的积极利用。

Identification of Representative Wind Power Fluctuation Patterns for Water Electrolysis Device Stress Testing: A Data Mining Approach

Wind power generation is expected to greatly contribute to the future of humanity as a promising source of renewable energy. However, the high variability inherent in wind is a challenge that hinders stable power generation. To utilize wind power as a primary energy source, integration with a polymer electrolyte membrane water electrolysis (PEMWE) system is proposed. Yet, PEMWE is known to suffer from degradation when exposed to input power patterns with high variability. This poses challenges to its commercialization. This necessitates stress testing with various wind power fluctuations during the production process of the devices. This study investigates representative patterns of wind power fluctuation so that these patterns can be used for the stress testing process. We employ data-mining techniques, including the swing door algorithm and k-means clustering, to identify these patterns by analyzing wind power generation data at a 10-s interval. As a result, the five most representative wind power ramps are presented. This study provides practical guidelines for the development process of expensive devices for wind power generation, thereby promoting the active utilization of wind power generation.

期刊介绍: The Korean Journal of Chemical Engineering provides a global forum for the dissemination of research in chemical engineering. The Journal publishes significant research results obtained in the Asia-Pacific region, and simultaneously introduces recent technical progress made in other areas of the world to this region. Submitted research papers must be of potential industrial significance and specifically concerned with chemical engineering. The editors will give preference to papers having a clearly stated practical scope and applicability in the areas of chemical engineering, and to those where new theoretical concepts are supported by new experimental details. The Journal also regularly publishes featured reviews on emerging and industrially important subjects of chemical engineering as well as selected papers presented at international conferences on the subjects.
