鲁棒优化(RO)是最近一种处理数据不确定性的优化方法。因为它是为了对冲输入数据中的任何扰动而导出的,所以(单阶段)RO模型的解决方案往往过于保守。为了解决这一问题,已经引入并研究了两阶段RO(以及更一般的多级RO),也称为鲁棒可调或自适应优化[3],其中第二阶段问题是在第一阶段决策做出并揭示不确定性后对决策进行建模。由于改进的建模能力,两阶段RO已成为一种流行的决策工具。应用包括网络/运输问题、组合优化和电力系统调度问题。 

近年来,我国风电发展迅速,风电已成为我国电能的主要来源之一。至2020年,我国的风电装机容量将占总装机容量的。风电大规模的集中式发展与接入对我国电网调度运行造成严重的影响。与传统能源不同,风电出力存在不确定性。2008年2月,美国德克萨斯州的风电出现大规模的爬坡事件,导致负荷削减事故[1];2008年6月,纽约上州因风暴导致250MW的风电场在8min内全部停机2。如果仍采用传统的日前调度方法,那么电力系统将会面临较大的风险。
考虑风电出力不确定性的机组组合问题本质上就是系统供电容量充裕性问题,目前该方面已有大量的研究成果,如基于场景的机组组合区间机组组合、机会约束机组组合、鲁棒机组组合等。基于机会约束的机组组合由于含有机会约束,因此其模型通常是非凸的,难以直接求解。基于场景的机组组合虽然有较好的经济性,但是该模型考虑大量风电出力场景集,使得整个模型规模较大,难以求解。为了解决这一问题,文献[10]提出考虑风电的区间机组组合。区间机组组合虽然求解速度较快,但是该模型并不能求解含离散随机变量的随机优化,如线路随机停运等4]。鲁棒机组组
合能有效解决上述问题,同时能保证系统运行的鲁棒性,并且该模型能通过 Benders分解、列生成算[法(column-and-constraint generation,C&CG)等方法求解,计算效率较高,因此得到广泛的应用。由于鲁棒调度结果往往过于保守,为了克服这缺点[12],文献[12]引入弱鲁棒理论,牺牲调度结果的鲁棒性以提升鲁棒机组组合的经济性。文献[13]将场景机组组合与鲁棒机组组合结合以降低鲁棒机组组合的保守性。
