以跨流域混联水电站群为研究对象,建立了系统总保证出力最大和总发电量最大模型。针对总保证出力最大模型,按流域进行分解并逐层优化求解,子系统通过递归优化策略实现协调,计算单元采用动态规划法求解保证出力maxmin模型;针对总发电量最大模型,分析保证出力处理方法,并提出保证出力廊道控制实用求解算法。应用建立的模型和提出的算法对多个水电站群进行联合调度获得了满意结果。
Taking the inter-basin mixed hydropower station as the research object, a system with the largest guaranteed total output and the largest total generating capacity was established. According to the maximum guarantee model of total guaranteed output, it is decomposed by watersheds and optimized layer by layer. Subsystem relies on recursive optimization strategy to achieve coordination. Computation unit uses dynamic programming to solve maxmin model to ensure maximum output. For maximum total generation model, , And put forward to ensure that the corridor control practical solution algorithm. Satisfactory results have been obtained by using the established model and the proposed algorithm to jointly schedule multiple hydropower stations.
