Using wave field data from the fifth generation ECMWF re analyses (ERA5) over the past 15 years
this study selects optimal locations for joint wave and wind energy power stations on islands off the Shandong Peninsula. Each site employs commercial wind turbines (WT) and wave energy converters (WEC) to form combined power stations. The study analyzes the potential benefits of these combined stations from multiple perspectives
including smoothing of power output
capacity factor
and downtime. The results indicate that the specific wind-wave installed capacity ratios at Dongzhudao
Zhuchadao
and Zhaitangdao significantly reduce the variability in power output and downtime of the combined stations
demonstrating a higher joint development potential compared to other islands. Additionally
the combined stations at all selected sites effectively reduce the duration of low power output.
