中文摘要：
以长江中上游15座骨干水库组成的大规模混联水库群联合发电优化调度问题作为研究对象,提出一种新的优化控制方法,其思路是:从流域梯级大规模电站群整体优化角度出发,以总发电量最大为目标建立大规模水库群分区优化调度模型,根据电站所属流域相对位置以及其水力补偿关系进行虚拟分区,以控制区内电站群子系统为对象进行分区优化控制;在此基础上,采用约束廊道法有效解决长期发电优化调度问题中的多约束耦合问题.将该方法应用到长江中上游大规模混联水库群联合发电优化调度问题的求解中,结果表明:所提出的方法求解精度高、时效性好,具有较强的工程实用性,为求解高维、复杂梯级水库群优化调度问题提供了一种新思路.
英文摘要：
Aiming at the optimization of hydropower system consisted of 15 reservoirs in Yangtze Riv-er ,a partition optimization control method was proposed .An optimal operation model was developed in the purpose of maximizing the cascaded hydropower plants′ total generated energy .The decision vectors were divided into small ones according to reservoir′s relative position and hydraulic relation-ship so as to reduce the high dimensions of decision space .To deal with constrained coupling problem , the constraint-corridor method was adapted .Finally ,this novel strategy was applied to the real casca-ded reservoir groups in Yangtze River .Results show that compared with the conventional method ,the proposed method has a competitive performance in not only convergence but also the computing time , w hich offers a new approach to solve high-dimensional and complicated optimization of reservoir dis-patching .
