摘　　要：为了提高系统在不确定运行环境下应对故障的调控能力,以含柔性直流输电技术(voltage source converter high voltage direct current,VSC-HVDC)的交直流系统为研究对象,提出一种综合风险管控与多阶段校正控制的储能分布鲁棒优化配置方法。通过在考虑最恶劣概率分布的情况下进行储能的配置决策,改善传统鲁棒规划方法过于保守的问题,提高潜在尾部风险度量结果的鲁棒性;同时,将日内校正控制划分成无故障、故障短期与长期3个校正阶段,并通过最大化所配置储能、柔性负荷以及VSC的快速校正能力,弥补常规调控装置难以快速响应指令的缺陷。针对所提配置模型,在列和约束生成算法(column and constraint generation,C&CG)和Multi-cut Benders分解算法的基础上,提出一种双循环分解快速求解算法,通过返回多割约束的方式,降低模型规模、提高求解效率。最终,在改进的IEEE RTS 79测试系统中验证所提模型与方法的有效性。In order to improve the regulating ability for dealing with contingency under uncertain environments,this paper proposes a distributional robust configuration of energy storage containing the risk management and multi-stage security correction for hybrid AC/DC grids by taking the voltage source converter high voltage direct current(VSC-HVDC)as a research object.The worst probability distribution of random factors is taken into consideration,thus the configuration results of energy storage is less conservative when compared with the conventional robust planning methods,and the robustness of the potential tail risk measurement are improved.To fully utilize the fast correction ability of the planning storage,the flexible load and VSC can make-up for the slow responding speed of traditional control resources.The corrective control in daily stage is divided into the pre-contingency,short-term and long-term post-contingency control.Combined the column and constraint generation method(C&CG)with multi-cut benders decomposition method,a double-cycle decomposition method is employed for the proposed model,which reduces the model scale and improves the computational efficiency by returning the multi-cut constraints.The effectiveness of the proposed model and algorithm is validated in the modified IEEE RTS 79 tested system.
