摘　　要：针对水电系统长期耗能最小问题设计了求解方法:首先定义一个搜索方向集,然后按等微增率原理,依次按对目标有利程度的大小顺序选择搜索方向逐时段进行系统负荷平衡。通过对福建水电站系统的应用,证明长期耗能最小发电调度模型及其求解方法具有耗时较少、能有效减少弃水等优点。In the hydropower systems the problem of energy consumption minimization can be simply expressed as follows: given a load demand process, schedule the generation of hydroplants such that the potential energy at the endofstudy is maximal. To solve this problem, this paper designs a procedure, in which a set of search directions is firstly defined, and then based on the principle of reaching equal incremental, one of the defined directions is selected at a time, in order to improve the objective, under condition to meet the power demand stage by stage. With application to Fujian hydroplant systems, the model of energy consumption minimization and its solving method are practically tested efficiently.
