In this paper, a series of problems currently faced of small cascade hydropower stations such as generating instability and large impact on downstream ecological environment. A new optimization scheduling is proposed--ensure the ecological flow generation stability under optimal criteria entire cascade hydropower stations, make the hydropower output adapt to local electricity consumption by the characteristics of small hydropower flexible start and stop in the power generation to achieve the purpose of simplifying the scheduling.%本文针对目前小型梯级水电站面临的一系列问题诸如发电不稳定、对下游生态环境影响大等问题，提出了一种新的优化调度方式———在保证生态流量下以整个梯级水电站发电稳定为最优准则，同时在发电的时候充分利用小型水电站启停灵活的特点，使水电站出力与当地的用电情况相适应，以达到简化调度的目的。
