考虑到梯级电站联合运行及电站投入运行过程容量增长的跳跃性特征，建立了以折现投资和累计过剩容量最小化为目标、嵌入水库联调优化问题的多目标复合排序模型．电站投入的序及投入时间的两维优化问题转化成只需对序进行优化的一维问题给出了理论证明．提出多目标动态规划的非劣解生成技术———直接向量优化法，并给出了理论证明．
Considering the hopping characteristics of cascade hydropower station operation and capacity growth during the operation of hydropower station, a multi-objective compound sequencing model of intermodal interoperability optimization was established with the goal of minimizing discounted investment and accumulative excess capacity. The two-dimensional optimization problem of power plant input sequence and investment time is transformed into a one-dimensional problem that only needs to be optimized. Proposed multi-objective dynamic programming non-inferior solution generation --- direct vector optimization method, and gives a theoretical proof.
