【摘要】 本文采用多维随机动态规划,解决三库七个水电站联合优化调度的问题。根据实例条件,对其中两个水库制定了“同步蓄放”的拟优原则,使三库问题概化为两库的数学模型。文中针对库群调度中某个水库受到极限水位制约,不能按指示决策工作的情况,首次提出了一种新的补偿调度原则,以此来指导优化策略的选择。同时,对相应的寻优方法也作了改进。从时历操作结果对比来看,优化效益显著。可见模型的概化和应用是成功的。更多还原

【Abstract】 In this paper, a working example is introduced for the multidimensional stochastic dynamic programming for optimal regulation of an electric power system consisting of three reservoirs and seven water power plants in series in Guizhou province. According to the actual conditions of the example, a quasi-optimal principle of "synchronous storage and release" is made for two reservoirs of the system, simplifying the three-reservoir problem into a two-reservoir mathematical model. A new principle of "compensative regulation" is presented in this paper for the case that when in regulation a reservoir of the system cannot operate in accordance with directive decisions as a result of restriction of control water levels. The search method is modified accordingly. The method is applied and tested in the mathematical model, resulting in obviously better benefits compared with the traditional method.更多还原
