摘要
随着各类生命线网络间关联日益紧密,对关联生命线网络进行韧性研究刻不容缓。以地震灾害为背景,构建了城市电-气关联生命线网络韧性评估框架,并基于电力潮流分析和天然气稳态仿真分析,建立了考虑电力网络和燃气网络功能特性的性能评价指标。同时,以关联的IEEE30节点网络和20节点燃气网络为案例,结合评估框架分析网络韧性在不同恢复预算和恢复资源下的变化规律,为资源优化配置提供依据,为建设“韧性城市”提供支撑。
It is critical to conduct research on the resilience of related lifeline networks,as various lifeline networks are increasingly closely related.This article aims to build a framework for assessing the resilience of urban electricity-gas related lifeline networks based on the earthquake disaster.A performance response function(PRF)considering the functional characteristics of the power and gas network will be conducted by analyzing the power flow and natural gas steady-state simulation.In the meanwhile,taking the interdependent IEEE 30-bus network and Belgium 20-node gas network as cases combined with the evaluation framework,the changes of network resilience under different recovery budgets and recovery resources are analyzed.This analysis provides a basis for the optimal allocation of resources and supports the construction of a“resilient city”.
