台风灾害给新能源占比不断提高的电-气综合能源系统（integrated electricity-gas system，IEGS）安全稳定运行带来巨大挑战，针对目前IEGS灾中应急调度研究缺乏对台风迁移及风电波动的考虑，文章提出了一种综合考虑台风时空特性及严重风电波动的IEGS灾中应急调度方法。建立台风时空模型，量化风雨影响下电-气系统元件故障时变特性，并利用信息熵理论筛选典型故障场景；基于台风的时序迁移，建立IEGS双层灾中应急调度模型，上层电力系统侧为应急鲁棒调度模型，其主问题针对台风路径下高危线路进行应急调度，子问题优化下一时刻最严重风电波动下系统的最小失负荷量，下层天然气系统侧基于信息耦合交互为电力侧提供恢复支撑，优化灾害下气网的运行状态；采取自适应交替方向乘子法（adaptive-alternating direction method of multipliers，AT-ADMM）分布式算法进行模型求解。最后通过算例验证了所提方法的有效性。
英文摘要:
Typhoon disasters bring great challenges to the safe and stable operation of integrated electric-gas system (IEGS), which is increasingly occupied by new energy sources. Considering the lack of consideration of typhoon migration and wind power fluctuation in emergency dispatching research of IEGS during disasters, an IEGS emergency scheduling method considering the spatio-temporal characteristic of typhoon and severe wind power fluctuations is proposed in this paper. A spatio-temporal model of typhoon is established to quantify the time-varying fault characteristics of electricity-gas system components under the influence of wind and rain, and typical fault scenarios are screened by information entropy theory. Based on the timing-sequence migration of typhoon, IEGS double-layer emergency dispatching model in disaster is established. The upper power system side is the emergency robust dispatching model. The main problem is emergency dispatching for high-risk lines under the typhoon path, and the sub-problem optimizes the minimum load loss of the system under the most severe wind power fluctuations at the next moment. The lower natural gas system side provides the recovery support for the power side based on the information coupling interaction to optimize the operating state of the gas network under the disaster. The adaptive-alternating direction method of multipliers (AT-ADMM) algorithm is adopted to solve the model. An example is given to verify the effectiveness of the proposed method.
