【摘要】 本文提出一种按机组最佳与次最佳组合求取电力系统机组开停机计划的有效方法。这个机组组合是用在研究周期内所予计的负荷峰谷值来计算的,而且只是在机组检修计划变更时才予以重算。本文应用了带分枝限定的混合动态规划法。此方法大大减少了需用的计算机内存和计算时间,可用于求解大型电力系统的机组投入问题。更多还原

【Abstract】 This paper presents an efficient method to work out the unit startup and shutdown schedule in electric power system based on the optimal and suboptimal unit combination. The unit combination is calculated with the peak and valley value of load forecast during the studied period, and recalculated only in the case of changing the unit maintenace schedule. A hybrid dynamic programming/banch-and-bonud approch is used in the paper.This method reduces considerably the memory space and time needed for computation, and can be used for unit eommitment更多还原
