摘　　要：地震灾害具有难预测、波及广等特点,在低震级或非震中地区,虽然不会造成建筑物倒塌、人员伤亡等,但可能会破坏架空电力线路和地下管道,对供能系统产生较大影响。文中针对电-气-热综合能源系统,提出地震灾前规划和应急响应预案制定、灾时抢先地震波传播时间差完成负荷超前转供的多时间尺度韧性提升方法。首先,建立了地震影响的综合能源系统网格化故障概率模型。其次,在解耦框架下提出了综合能源系统的双环最优负荷削减模型,并考虑建筑物热惯性的负荷满意度,提出韧性评估和多时间尺度韧性提升方法。最后,通过仿真算例验证了该方法的有效性。Earthquake disasters have the characteristics of low predictability and wide impact.In low magnitude or non-epicenter areas,although ground vibrations do not cause building collapse or casualties,they may damage overhead power lines and underground pipelines,and have a significant impact on energy supply systems.Therefore,this paper proposes a multi-timescale resilience enhancement method for the electricity-gas-heat integrated energy system,which includes pre-earthquake planning and emergency response plan formulation,as well as preemptive seismic wave propagation time difference during disasters to complete load forwarding in advance.Firstly,this paper establishes a grid-based fault probability model for the integrated energy system affected by earthquakes.Secondly,this paper proposes a dual-loop optimal load reduction model for integrated energy systems within a decoupling framework.Considering the load satisfaction of building thermal inertia,this paper proposes resilience assessment and multi-timescale resilience improvement methods.Finally,The effectiveness of the method is verified by simulation cases.
