Optimal Operation of Integrated Energy System Considering Flexible Emergency Resource Coordination Under Ice Disaster

Extreme ice disasters can cause frequent blackouts and shutdowns. Flexible Emergency Resources （FERs） play a complementary role. Coordinating multiple FERs to participate in scheduling facilitates system recovery. This study proposes an integrated energy system operation framework that considers FER coordination during ice disasters. In the pre-disaster prevention stage， a robust optimization model is constructed to solve the FER pre-scheduling scheme. In the post-disaster resistance and recovery phases， a two-layer optimization model of an integrated energy system considering the FER is established. Emergency repair of the upper line and load reduction of the lower node are transmitted in real-time to realize rapid emergency repair. Simultaneously， the system scheduling is optimized by the mobile energy storage team to reduce the comprehensive load reduction rate of the system and improve flexibility. The case study shows that the proposed framework can effectively reduce the comprehensive load reduction rate by 32.16 % and improve the ability of the system to resist disasters.
