【摘要】 我国沿海地区频繁遭受的台风灾害常常对电力系统造成巨大的经济损失，配电网因设计标准相对较低在台风中易受重创。针对这一问题，提出了一种结合快速重构与灵活孤岛划分的配电网应对策略，以有效模拟并量化台风对电网的影响，并执行紧急灾害响应措施。首先，利用真实台风事件的历史数据构建了台风风场模型，模拟台风轨迹和风速的变化。然后，采用设备脆弱性曲线和蒙特卡洛抽样法，评估电网组件的失效概率，并构建故障场景。配电网灾害应对模型综合考虑了快速重构和孤岛微电网的划分，通过最大密度的辐射状约束优化重构操作。最后，通过对广东某地在台风“天鸽”影响期间的配电网案例进行分析，验证了该模型能通过优化重构和孤岛运行显著减少负荷损失，为台风灾害下电网的快速恢复提供了重要的技术支持和理论依据。更多还原

【Abstract】 Frequent typhoons in China’s coastal regions often result in substantial economic losses to the power systems. Particularly vulnerable are distribution networks due to relatively lower design standards, which suffer significant damage during typhoons. This study proposes a strategy for distribution networks that combines rapid reconfiguration and flexible microgrid isolation to effectively simulate and quantify the impact of typhoons on electrical grids and implement emergency disaster response measures. Initially,the study constructs a typhoon wind field model using historical data from actual typhoon events to simulate the trajectories and variations in wind speeds. Subsequently, it assesses the failure probability of grid components using vulnerability curves and Monte Carlo sampling methods to establish fault scenarios. Additionally, the disaster response model developed in this research considers both rapid reconfiguration and isolated microgrid operations of the distribution network, optimizing reconstruction operations through maximum density radial constraints. Case analysis of a distribution network in Guangdong during the impact of Typhoon Hato demonstrates that the model significantly reduces load losses through optimized restructuring and island operations, providing vital technical support and a theoretical basis for the rapid recovery of grids following typhoon disasters.更多还原
