| 摘要: |
| 极端事件引发的大规模停电不仅造成供电中断和经济损失，还可能影响城市生命线系统的功能水平，进而引发跨系统故障并威胁公共安全。然而，目前仍缺乏统一的韧性评估指标体系及量化方法，难以全面准确评估灾害影响和城市电网的韧性水平。针对这一问题，提出了考虑公共安全影响的城市电网韧性评估指标体系及量化分析方法：从电网属性特征、经济社会影响及事件特有指标3个维度构建了多层级韧性评估指标体系，并提出了各指标的量化计算方法；提出了融合序关系分析法(G1法)与经熵权法优化的基于指标间相关性的权重确定法(改进CRITIC法)的主客观赋权方法，以确定指标的综合权重，并据此实现对上层指标的综合计算。通过某城市电网实际算例和构建的城市电网-城市生命线耦合测试系统分析，综合评估了电网的韧性水平，验证了所提韧性评估指标体系和量化分析方法的有效性。 |

| Abstract: |
| Large-scale blackouts caused by extreme events not only cause electricity supply interruption and economic losses, but also may affect the functional level of urban lifeline systems. Such disruptions can trigger cross-system failures and threaten public safety. However, there is still a lack of unified resilience assessment indicator system and corresponding quantitative method, making it difficult to comprehensively and accurately assess the impact of disasters and the resilience level of urban power grid. To address this issue, a resilience assessment indicator system and quantitative analysis method for urban power grid that explicitly considers public safety impacts is proposed. A multi-level resilience assessment indicator system is established across three dimensions: power grid attributes, socio-economic impacts and event-specific characteristics. Quantitative calculation methods for each indicator are proposed. An integrated weighting method combining subjective and objective approaches is introduced. This method integrates the order relation analysis method(G1 method) with an improved criteria importance through intercriteria correlation method(improved CRITIC method) optimized by the entropy weight method to determine the comprehensive weights of indicators. These weights are then used to compute higher-level aggregate indicators. The resilience level of urban power grid is comprehensively assessed through a case study based on an actual urban power grid and a constructed coupled urban power grid-urban lifeline test system, and the effectiveness of the proposed resilience assessment indicator system and quantitative analysis method is validated. |
