    摘要:

    由于极端事件会对电力系统安全造成巨大影响,提升电网韧性成为研究热点。为此,提出一种考虑智能软开关及多种应急资源的灾前预防?灾后协同恢复策略,以提高配电系统韧性。在灾前阶段,为有效减少资源灾后调度时间,以预测故障场景为依据,构建计及电源出力不确定性的鲁棒优化模型,采用列和约束生成算法求解,得到预布点决策方案;在灾后阶段,以动态调度最小化负荷削减功率为目标,结合灾前预布点和交通网路况,制定智能软开关和多种应急资源协同恢复策略;针对多源恢复模型的计算复杂性问题,设计辅助诱导目标函数加速算法,加快求解速度;通过改进IEEE 33节点配电系统算例,验证所提策略可提升配电网韧性。

    Abstract:

    In view of the significant impact of extreme events on power system security, enhancing grid resilience has become a research hotspot. Therefore, a pre-event prevention and post-event coordinated recovery strategy considering intelligent soft open points (SOPs) and multiple emergency resources is proposed to improve the resilience of the distribution system. In the pre-event stage, to effectively reduce post-event resource scheduling time, a robust optimization model considering the uncertainty of power output is constructed based on predicted fault scenarios. A column-and-constraint generation algorithm is used to obtain pre-event deployment decisions. In the post-event stage, to minimize the curtailed load power through dynamic scheduling, a coordinated recovery strategy using intelligent SOPs and multiple emergency resources is developed, combined with pre-event deployment decisions and traffic network conditions. To address the computational complexity of the multi-source recovery model, an auxiliary induction objective function acceleration algorithm is designed to speed up the solution. Finally, the effectiveness of the proposed strategy in improving the distribution network resilience is verified using an improved IEEE 33-node distribution system case study.
