Special Session VII: Vulnerability Identification and Security Defense of New Power Systems

Session Chair: Lecture, Rui Cheng, North China Electric Power University, China	Co-Chair: Prof., Junjie Hu, North China Electric Power University, China

Information: This session focuses on the emerging vulnerability patterns and security defense challenges faced by new power systems under the background of high-penetration renewable energy integration, prominent power-electronics-dominated characteristics, and multi-energy complementarity and coupling. Through invited expert reports and in-depth discussions, we systematically analyze the multi-dimensional causes of system vulnerability (including topological weaknesses, cyber-physical coupling risks, extreme event impacts, etc.), and explore identification methods and proactive defense strategies based on cutting-edge technologies such as artificial intelligence, digital twins, and attack-defense game theory. The session will pay special attention to resilience enhancement strategies for new power systems, cascading failure blocking mechanisms, and coordinated security dispatching of source‑grid‑load‑storage, aiming to provide theoretical support and practical guidelines for building self-healing and survivable new power systems.

Topics of interest include, but are not limited to:

1. Vulnerability identification methods for new power systems
2. Risk assessment and security defense strategies for cyber-physical power systems
3. Resilience assessment and enhancement strategies for power systems under extreme weather and natural disasters
4. Survivability assessment of new power systems under unconventional extreme events
5. Spatiotemporal propagation mechanisms, fast simulation, and blocking technologies for cascading failures
6. Security-constrained dispatching and risk-balancing methods in source‑grid‑load‑storage coordinated optimization
7. Applications of artificial intelligence (deep learning, reinforcement learning) in security early warning and emergency decision‑making for power systems
8. Digital‑twin‑driven power security situational awareness and dynamic defense wargaming
9. Attack‑defense game modeling for new power systems
10. Coupled risk modeling and coordinated security control for multi‑energy complementary systems
