我国沿海城市频繁遭受超强台风侵袭，导致配电网故障频发和重大停电经济损失。为增强配电网的抗灾能力及供电可靠性，提出了一种基于台风预测数据的优化策略，模拟台风引发的强风和暴雨灾害，并采用蒙特卡洛抽样法对线路和负荷节点的故障进行模拟。策略优化分配分布式电源和有限的主网供电资源，优先保障重要负荷供电，制定最优切负荷方案，实现灾时资源灵活调整和负荷优化。灾后通过配电网重构和应急电源车调度，以降低缺供电经济损失和提升可再生能源利用率为目标，优化线路开关状态和应急电源车的接入位置。IEEE 33配电系统仿真结果表明，该策略在台风期间有效减少停电损失，并在灾后扩大复电区域，提升复电性能和应急响应能力。所提策略为台风灾害下的最优切负荷和灾后保供电提供创新方案，有效增强了城市配电网在面对极端灾害时的抗灾能力和供电可靠性。

Coastal cities in China frequently suffer from super typhoon invasions, leading to frequent distribution network failures and significant economic losses due to power outages. To enhance the disaster resilience and power supply reliability of the distribution network, an optimization strategy is proposed based on typhoon forecast data, simulating strong winds and heavy rainfall disasters caused by typhoons, and using Monte Carlo sampling to simulate faults in lines and load nodes. The strategy optimizes the allocation of distributed power sources and limited main grid power resources, prioritizes the power supply to critical loads, and formulates an optimal load shedding scheme to achieve flexible adjustment of resources and load optimization during disasters. Post-disaster, the strategy utilizes distribution network reconfiguration and emergency power vehicle dispatch to reduce economic losses due to power shortages and enhance the utilization rate of renewable energy, optimizing line switch states and the access locations of emergency power vehicles. Simulation analysis is conducted on the IEEE 33 distribution system indicate that this strategy effectively reduces power outage losses during typhoons and expands the power restoration area post-disaster, enhancing restoration performance and emergency response capabilities. The proposed strategy provides an innovative solution for optimal load shedding during typhoon disasters and post-disaster power supply assurance, effectively enhancing the disaster resilience and power supply reliability of urban distribution networks facing extreme disasters.
