摘　　要：为提升电力系统弹性,确保主网应对小概率-高影响事件的能力,基于鲁棒优化理论提出主网灵活控制装置配置的规划框架,充分考虑远动开关配置下的最优线路开断(optimal transmission switch,OTS)、线路强化加固装置以及储能设施之间的最优协同作用,最大限度降低投资运行成本的同时减少由潜在极端事件造成的经济损失。首先,基于持续负荷曲线构建考虑典型日线路中断与新能源出力波动的两阶段鲁棒规划模型;然后,采用修改后的嵌套列和约束生成算法(nested column-and-constraints generation,NCCG)对模型进行求解,使用相关加速策略提升模型求解效率;最后,通过IEEE-24节点系统进行仿真分析,验证异质灵活控制装置之间的规划协同作用以及模型的有效性。To enhance power system resilience and ensure the capability of transmission grid to handle the events of low-probability but high impacts,a flexible control device configuration planning framework for transmission network is proposed based on robust optimization theory.This framework fully considers the optimal synergy among different categories of control devices,including optimal transmission switch(OTS)under remote switch configuration,transmission line reinforcement devices and energy storage systems(ESS),aiming to minimize the operational costs while reducing the economic losses caused by extreme events.Firstly,a two-stage robust planning model is constructed based on the load duration curves(LDC),considering typical daily interruptions of transmission lines and renewable energy output fluctuations.And then,the modified Nested Column-and-Constraints Generation(NCCG)algorithm is employed to solve the proposed model,and relevant acceleration strategies are utilized to enhance the computational efficiency.Finally,a simulation analysis is conducted using the IEEE 24-bus system to validate the planning synergy among different flexible control devices and to assess the effectiveness of the proposed model.This work is supported by Science and Technology Project of China Southern Power Grid Corporation(No.036000KK52200061).
