水电站负荷优化分配的分解聚合原理及应用
Derivation of the aggregation-decomposition principle for optimal load distribution of hydropower station
摘要
Abstract
Inner-plant economical operation is the key factor of improving water power utilization efficiency of hydropower station,while the solution to the optimal load distribution (OLD) model is heavily restricted by the complex hydraulic connection and constraints.Aiming at this issue,this paper presents an OLD model for the hydropower station with complex conduit systems through analyzing the complex hydraulic connection between the conduit systems and the relationship among units' dynamic indexes and decomposing the complex system into different subsystems with imparity level according to the distributary node.Then this pa per proposes a stratified hierarchical structured method to solve the complex conduit systems hydropower station OLD model by constituting the parallel units (series units) with the same unit-block water-head (unit flow) as an equivalent unit in subsystem.The principle and method are not only simple and clear,but also have some advantages such as flexibility,practicality and generality,which will lead to a promising prospect when it comes to the field of the parallel computing means dealing with the short-term optimal operation problem of giant-scale hydropower plant groups.The efficiency,adaptation and stability of the principle and method has been testified by the case study.关键词
