摘　　要：阻塞费用分摊是阻塞管理的重要内容之一。目前的基于 AUMANN-SHAPLEY 值的分摊方法需采用近似的离散数值积分方法,需多次求解系统最优潮流,不利于大系统应用。该文分析了 DC 潮流约束下阻塞消除过程中最优解及其灵敏度的变化规律,提出了基于贡献因子理论的阻塞费用简捷分摊方法。与现有方法相比,该文方法的显著特点是:阻塞费用分摊可采用连续积分方法,而不是近似的离散数值积分方法。交流潮流约束下也可采用文中方法。Congestion cost allocation is important for congestion management. The allocation methods based on Aumann-Shapley use discrete intogration method and need to solve the OPF for many times, they are not suitable for large scale system application. The optimum solution and their sensitivity changes during congestion releas-ing by using DC OPF are analyzed. Simple method based on contribution theory is proposed for congestion cost allocation. Compared with the current methods, the proposed method uses continuous integra- tion rather than discrete numerical integration to allocate the congestion cost. The proposed method needs less computation the method can also be used forAC OPF congestion management.
