Abstract

In order to unveil the probability and severity of low wind power events during severe cold weather in northeastern China, hourly historical meteorological data from 1979 to 2022 were used to reconstruct wind power output data. The occurrence of low wind power events was identified on the basis of wind power output capacity factors falling below a designated threshold, thereby reproducing the low wind power event that resulted in widespread power restrictions in late September 2021. A long-term low wind power event lasting seven days in late July 2009 was also identified. The annual frequency, seasonal distribution, and duration of low wind power events were analyzed. A study of low wind power events during the heating season revealed 300 instances occurig at temperature below -15. Furthermore, the analysis demonstrated a strong correlation between low wind power during the heating season and cold waves occurrences.

Key words

low wind power event / power system reliability / wind power / cold wave / power system planning
