摘　　要：为实现电气互联系统韧性的量化提升,文中提出了一种基于全局灵敏度分析的韧性提升方法。首先,通过推导得到基于影响增量的全局灵敏度,可以定量分析元件失效概率参数同时变化对韧性指标的共同影响。然后,全局灵敏度被引入预算限制场景和韧性达标约束场景下的元件强化方案优化模型中,以设计经济、有效的韧性提升方案。最后,以一次地震灾害场景下的电气互联系统为算例,验证了所提方法的有效性。To achieve quantitative improvement of the resilience of the electricity-gas interconnection system, this paper proposes a resilience improvement method based on global sensitivity analysis. First, the impact-increment-based global sensitivity is derived for quantitatively analyzing the joint impact of simultaneous changes in component failure probability parameters on the resilience index. Then, the global sensitivity is introduced into the optimization model of the component enhancement scheme in the scenarios of the budget limitation and the resilience qualified constraint, so as to design a cost-effective resilience enhancement scheme.Finally, the effectiveness of the proposed method is verified by taking an electricity-gas interconnection system in an earthquake disaster scenario as an example.
