结合黄河干流水库群（包括水电站）实例，本文建立了优化调度模型，采用大系统分解协调原理推导了模型的求解算法，并给出了详细的求解步骤。应用文中建立的模型和提出的算法对黄河干流水库联合调度获得了满意的成果。 Combined with the example of Yellow River mainstream reservoir group (including hydropower station), this paper establishes an optimal scheduling model, and uses the principle of large-scale system decomposition and coordination to derive the algorithm for solving the model and gives detailed solution steps. The model and the proposed algorithm are applied to the joint operation of Yellow River mainstream reservoir obtained satisfactory results.
