摘　　要：台风等极端天气灾害给含大量海上风电场(offshore wind farms,OWFs)的输配电网中重要负荷的安全可靠供电带来很大挑战。为了保障灾后重要负荷的快速恢复供电,首先,基于台风天气下强风和雷击造成的故障场景,建立了一个含多OWFs的输配电网的韧性恢复调度模型。模型中以最小化总恢复调度成本为目标,全面考虑了输电网、配电网和OWFs中的多种恢复措施,协调优化各种可调度资源,以快速恢复重要负荷的供电,提升台风天气下系统的韧性。然后,提出了一种基于双层交替迭代的自适应交替方向乘子法将所建立的含大量离散变量的韧性恢复调度模型分解为输电网、每个配电网和每个OWF多个子优化模型的分布式求解,以高效获得最优韧性恢复调度方案。最后,对接入了2个配电网和2个OWFs的修改IEEE 39节点系统进行算例分析,验证了所提出模型和算法的可行性和有效性。Extreme weather disasters,such as typhoons,will pose significant challenges to the secure and reliable power supply of important loads in the integrated transmission and distribution networks with many offshore wind farms(OWFs).To ensure the rapid restoration of power supply for important loads after disasters,a resilient restoration dispatch model of integrated transmission and distribution networks with multiple OWFs is established based on the fault scenario caused by strong winds and lightning strikes under typhoon weather.This model comprehensively considers various restoration measures of the transmission network,distribution networks,and OWFs,aiming to minimize the total restoration dispatch cost.And various dispatchable resources are coordinatedly optimized to rapidly restore power supply for important loads and enhance the power system's resilience under typhoon weather.Then,a bi-level alternating iteration-based adaptive alternating direction method of multipliers is proposed to decompose the established resilient restoration dispatch model with lots of discrete variables into multiple sub-optimization models of the transmission network,each distribution network,and each OWF for a distributed solution and obtain the optimal resilient restoration dispatch scheme efficiently.Finally,a case study on the modified IEEE 39-bus system integrated with two distribution networks and two OWFs demonstrates the feasibility and effectiveness of the proposed model and algorithm.
