摘　　要：提出一种确定火电厂负荷经济调度的改进动态规划方法.先按优先顺序法压缩各时段机组组合状态,再用动态规划法进行计算.新的方法克服了优先顺序法没有考虑启停耗量的不足,也解决了动态规划法的“维数灾”及难于处理的爬坡速度约束问题,且各机组的最优负荷分配与机组的最优启停计划可以同时计算出.An advanced dynamic programming of load economic dispatching for thermal Power Station is presented. Optimal unit commitment is determined by dynamic programming on the basis of using priority list to limit the combination states. Not only does the new method calculate the start-up consumption that the priority list can't consider, but also it resolves the dimension problem and the ramp constraint of dynamic programming. The optimal unit commitment simultaneously with economic dispatch can be calculated.
