Abstract

According to different studies, the ascending trend of blackouts in recent years suggests that today’s power system is becoming increasingly vulnerable to severe weather and puts an accent on an emerging issue that deals with power system resilience. Power system resilience is the ability to limit the extent, severity, and duration of system degradation following an extreme event. In our quest to further comprehend and enhance the resilience, we conducted an extensive analysis of outage statistics in Sweden spanning the period from 2007 to 2019. This dataset was sourced from Energiföretagen Sverige. Our analysis reveals that roughly 26% of all outages can be attributed to weather-related events. These weather-related disruptions not only affect one-third of the customers but also significantly contribute to the customer outage time. This, in turn, directly impacts the overall reliability and resilience of the power system. Therefore, it is crucial to adopt effective strategies for addressing these events to mitigate their adverse effects. For that reason, detail meteorological data is needed for further analysis.
