三峡梯级电站短期优化调度的模糊多目标动态规划

针对三峡梯级电站的短期优化调度是一个具有复杂约束条件的大型、动态、有时滞、模糊非线性的优化问题，本文建立了模糊优化调度模型，并对其进行了求解。由于常规模糊动态规划的方法在库容变化大的时候会出现维数灾，因此本文利用模糊多目标动态规划法，并结合逐次逼近方法，来求解梯级短期优化调度问题。实例仿真结果表明，它不仅可以根据不同的参数选择生成非劣解集，还可以推荐满意解，为决策支持提供依据。

Short-term optimal scheduling of cascade hydropower stations usingfuzzy multi-objective dynamic programming

A fuzzy optimal model for short-term scheduling of the cascade hydropower stations in the Yangtze River including the Three Gorges Project and Gezhouba Project was established. In view of the curse of dimensionality will occur to the calculation of traditional fuzzy dynamic programming due to significant variation of reservoir storage, a fuzzy multi-objective dynamic programming method is proposed. The optimal scheduling can be obtained by combining this method with successive approximation method. The numerical simulation result shows that not only the noninferior solutions can be generated according to different parameters, but also the satisfactory solution can be found.
