台风灾害下考虑资源协同的配电网综合韧性提升策略

Comprehensive resilience improvement strategy of distribution network considering multi-resource coordination under typhoon disasters

  • 摘要: 全球气候变化导致台风频发、强度增加,严重威胁沿海地区电力系统的安全与稳定运行。现有研究重点集中灾后资源调度,未充分考虑灾前防御规划和应急资源协同控制。本文对此展开研究,提出一种台风灾害下考虑资源协同的配电网综合韧性提升策略。首先结合台风历史数据构建风电场模型和电力线路模型,其次建立灾前预置-灾后应急资源协同模型,并充分考虑灾前预置和道路网络状况,以及智能软开关和应急资源协同恢复策略,再次采用列与约束生成方法求解混合整数二阶规划模型,最后结合改进IEEE33节点配电系统算例为例进行验证,结果表明,所提策略能够有效提升电网的综合韧性和供电的可靠性。

     

    Abstract: Global climate change has led to the frequency and intensity of typhoons, which seriously threatens the safe and stable operation of power systems in coastal areas.The existing research focuses on post-disaster resource scheduling, and does not fully consider pre-disaster defense planning and collaborative control of emergency resources.This paper conducts research on this and proposes a comprehensive resilience improvement strategy for distribution networks that considers resource synergy under typhoon disasters.First, the wind farm model and power line model are constructed based on the historical data of the typhoon, and secondly, the pre-disaster preset-post-disaster emergency resource collaborative model is established, and the pre-disaster preset and road network conditions are fully considered, as well as the intelligent soft switch and emergency resource collaborative recovery strategy, the column and constraint generation method is used again to solve the mixed integer second-order planning model, and finally combined with the improved IEEE33 node power distribution system as an example for verification, the results show that the proposed strategy can effectively improve the comprehensive resilience of the power grid and the reliability of power supply.
