| 摘要: |
| 台风等极端气象灾害对配电网的安全稳定运行构成严重威胁，提升配电网抵御能力和灾后恢复能力是保障电力供应的关键。提出一种面向台风灾害的配电网韧性提升方法，构建涵盖灾前预防、灾中控制及灾后恢复的多阶段耦合策略，以降低极端事件带来的经济损失与负荷损失。对台风影响下的线路元件进行力学建模，量化结构损伤程度，基于此构建线路故障概率模型。结合台风灾害下不同配电网节点的运行状态，提出多阶段脆弱度评估指标，实现配电网脆弱环节的精准识别。设计考虑差异化动态调度的三阶段韧性提升策略。以IEEE 33节点配电网为算例，验证所提方法在提升系统抗灾能力、运行经济性及恢复效率方面的有效性和可行性。 |

| Abstract: |
| The extreme meteorological disasters such as typhoon seriously threaten the safe and stable operation of distribution network, the improvement of resistibility and post-disaster recovery capability of distribution network is the key of ensuring power supply. A resilience improvement method for distribution network facing typhoon disaster is proposed, and a multi-stage coupling strategy covering pre-disaster prevention, in-disaster control and post-disaster recovery is constructed to reduce the economic loss and load loss caused by extreme events. The mechanical modeling of line components under the influence of typhoon is carried out to quantify the structural damage degree, on this basis, a line failure probability model is constructed. Combining the operation status of different nodes in distribution network under typhoon disaster, a multi-stage vulnerability assessment index is proposed to achieve accurate identification of the vulnerable parts of distribution network. A three-stage resilience improvement strategy considering differentiated dyna-mic dispatch is designed. The IEEE 33-node distribution network is taken as an example to verify the effectiveness and feasibility of the proposed method in the aspects of improving system disaster resistibility, operation economy and recovery efficiency. |
