摘　　要：前一篇论文提出了鲁棒经济调度的理论框架,文中以大规模风电接入后的鲁棒机组组合和鲁棒备用整定问题为例,阐述了如何将其应用于实际调度问题。鲁棒机组组合旨在提供可靠的机组工作状态以应对给定集合内的不确定性,而鲁棒备用整定主要解决在不确定性偏离预测较大的情况下,系统调整到新的安全运行点的可达性问题。通过鲁棒机组组合和鲁棒备用整定这两个实例,阐述了如何应用鲁棒经济调度理论对实际问题建立模型,以及如何求解相应的问题,从而在不确定环境下提供可靠的发电计划。所提模型与算法的有效性在IEEE 39节点系统上得到了验证。A generalized framework of power system robust dispatch is suggested in the previous paper that places the unit commitment problem and reserve adjustment problem under large scale wind energy integration as examples to demonstrate the practical application of the robust and economical scheduling methodology.The robust unit commitment （RUC） is aimed at providing optimal unit status decisions immune to all possible wind power variations within a pre-defined uncertainty set,while the robust reserve adjustment （RRA） tries to guarantee the reachability to a new secure operating condition when the forecast error of wind power generation is high.Through the two examples of RUC and RRA,this paper highlights the process of developing a robust model within the framework of robust and economical scheduling and the method of solving such a problem so as to provide more reliable and cost-effective operation in an uncertain environment.The effectiveness of our models and algorithm are validated on an IEEE 39-bus system.
