The invention discloses a cascade hydropower station economic dispatching successive dimension reduction method adaptive to complex constraints. The method is specifically implemented according to the following steps: 1, establishing an inter-plant economic operation objective function and an in-plant economic operation objective function; 2, setting constraint conditions for the inter-plant economic operation objective function and the in-plant economic operation objective function in the step 1; and 3, solving the inter-plant economic operation objective function by using a DRS-DSA algorithm. The method solves the problems that results obtained through an existing method are unstable, calculation time is long, and effectiveness is poor. 本发明公开了一种适应复杂约束的梯级水电站经济调度逐次降维方法，具体按照以下步骤实施：步骤1，建立厂间经济运行目标函数和厂内经济运行目标函数；步骤2，对步骤1的厂间经济运行目标函数和厂内经济运行目标函数设定约束条件；步骤3，采用DRS-DSA算法求解厂间经济运行目标函数。本发明方法解决了现有方法得到的结果不稳定、计算耗时长且有效性差的问题。
