摘　　要：考虑高渗透率分布式电源(distributed generation,DG)接入给配电网带来的影响,提出了一种计及配电网韧性的数据驱动鲁棒规划方法。首先提出了含高渗透率分布式电源的韧性综合评价体系;接着将三阶段规划模型转换成二阶段数据驱动鲁棒规划模型,完成对线路加固方案以及分布式电源位置和容量的最优配置;采用基于极限场景法的改进列约束生成算法(column-and-constraint generation,C&CG)对鲁棒模型进行求解。最后,通过算例分析所提韧性提升措施的效果。结果表明,所提方法能够有效量化配电网韧性,进而为含高渗透率分布式电源的韧性配电网规划提供参考。By considering the impact of high-permeability distributed generation access on distribution networks,a datadriven robust planning method that accounts for the resilience of a distribution network is proposed.First,a comprehensive resilience evaluation system with high-permeability distributed generation is proposed.The three-stage planning model is then transformed into a two-stage data-driven robust planning model to complete the decision-making of the line-reinforcement scheme and the optimal allocation of distributed generation location capacity.An improved column and constraint generation algorithm based on the limit scenario method is used to solve the robust model.Finally,an example is provided to analyze the effects of the proposed resilience improvement measures.The results show that the proposed method can effectively quantify the resilience of a distribution network and provide a reference for resilient distribution network planning with highpermeability distributed generation.
