台风灾害下综合能源系统薄弱环节识别与韧性调度策略
Vulnerability Identification and Resilience Scheduling Strategy for Integrated Energy Systems Under Typhoon Disasters
摘要
Abstract
[Objective]Low-probability,high-impact natural disasters have become increasingly frequent.Integrated energy systems with high renewable penetration often lack the self-adaptive optimization capability needed to manage unexpected disturbances.This paper proposes a vulnerability identification framework and a pre-disaster resilience-oriented dispatch strategy for integrated energy system under typhoon disasters.[Methods]A dynamic integrated energy systems model is constructed using a generalized phasor approach to represent heterogeneous energy flows.A line fault-restoration probability model under typhoon scenarios is developed to generate disaster-operational states.A vulnerability identification method is then introduced from the perspectives of system performance loss and power-flow transfer risk.Finally,a pre-disaster resilience scheduling strategy is formulated by integrating flexibility enhancement with power-flow optimization.[Results]Simulation results show that the optimized resilience-oriented dispatch strategy increases equivalent energy-storage capacity by 31.68%,reduces the average loading of key transmission branches by 56.58%,and decreases total load loss by 26.27%.[Conclusions]The proposed framework effectively identifies high-risk,critical vulnerabilities under extreme scenarios and substantially enhances the disaster resilience and supply security of integrated energy systems.关键词
