Abstract

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 suff er 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 fl uctuations during

the production process of the devices. This study investigates representative patterns of wind power fl uctuation 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 fi ve 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.
