计及来水量不确定性的梯级水电站发电调度研究

Study on generation dispatching of cascade hydropower station with uncertain water inflow

针对梯级水电站来水量的不确定性,建立了计及来水量不确定性的梯级水电站调峰调度模型。采用区间数来描述来水量的不确定性,并借鉴联系数理论,确定区间数之间的排序关系,从而将模型中带有区间数的约束条件进行清晰化处理,使不确定的优化问题得以用确定的优化方法来求解;通过算例分析验证了所提模型和方法的有效性。

Aiming at the uncertain water inflow of cascade hydropower regulation dispatching model, through which interval numbers are used station, this paper establishes the peak to describe uncertainty, and connection number theory to determine the sort relation among interval numbers. Therefore, the constraint conditions with interval numbers are clarified, which enables uncertain optimization to be solved by certain optimization. The analysis of examples verifies the efficiency of the mentioned model and methods.
