摘　　要：极端冰灾导致系统停电、停产事故频发,发挥灵活应急资源(flexible emergency resources,FER)互补优势,协调多种FER参与调度有助于系统恢复,提出了冰灾下考虑灵活应急资源协同的综合能源系统运行框架。在灾前-预防阶段,构建鲁棒优化模型,求解FER预调度方案;在灾后-抵御和恢复阶段,建立考虑FER的综合能源系统双层优化模型,上层线路抢修情况与下层节点负荷削减情况实时传递,实现快速抢修的同时,通过移动储能队伍优化系统调度,减小系统综合负荷削减率以提高弹性。算例分析表明,所提框架能够有效使综合负荷削减率减小32.16%,提高了系统抵御灾害能力。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 predisaster prevention stage,a robust optimization model is constructed to solve the FER pre-scheduling scheme.In the postdisaster 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.
