摘要
如何提高水量的利用率,增加发电效率,一直是水电调度研究的主要目标和方向,在传统优化调度的基础上,以水库不蓄水量的利用为出发点,构建了一种基于不蓄电能最大化的梯级水电站联合优化调度模型。通过对调度模型的分析及应用POA算法求解,并结合工程实例验证,充分说明了该模型和方法的合理性、可行性。相对于传统调度方式,提供的调度模型在满足多种约束条件下,可根据电网负荷需求的变化,通过合理调整梯级各电站的出力分配,提高不蓄水量的发电利用率,间接反映了对水资源的节约利用,同时有助于梯级水电站联合调度方式的安排,对梯级水电站的优化调度发展有一定的促进作用。
How to improve the utilization rate of water and increase the efficiency of power generation has always been the main goal and direction of hydropower dispatching research.Based on the traditional optimal dispatching,an optimal dispatching model of cascade hydropower station based on the maximization of unstored power is established in this paper,which takes the utilization of the unstored water of the reservoir as the starting point.Through an analysis of the dispatching model and the application of POA algorithm to solve it,and combined with the verification of an engineering example,the rationality and feasibility of the model and method are illustrated.Compared with the traditional dispatching mode,the dispatching model provided in this paper can improve the power generation utilization rate of unstored water by reasonably adjusting the output distribution of each cascade power station according to the change of power network load demand under various constraint conditions.It indirectly reflects the saving and utilization of water resources and is helpful to the arrangement of joint dispatching mode of cascade hydropower stations,and can promote the development of optimal dispatching of cascade hydropower stations to a certain extent.
