Analysis and Enlightenment of Power System Massive Blackout Accidents

The occurrence of massive blackouts has had a severe impact on both the social-economic fabric and the daily lives of the public. This paper analyzes massive blackout accidents worldwide to explore their primary causes, including natural disasters, equipment issues, imperfect management mechanisms, and human factors. The research indicates that natural disasters are the leading cause of massive blackouts, accounting for over 52% of cases. Equipment issues and human factors also contribute to a significant proportion. To ensure the safe and stable operation of power systems, this paper proposes targeted recommendations, including enhancing the resilience of power systems, improving management mechanisms, strengthening protections against human-induced incidents, and bolstering cybersecurity defenses. These measures aim to draw on lessons from past accidents while improving the overall risk resistance ability of power systems to better address potential future power crises.
