大规模水电站群短期发电优化调度算法改进

大规模水电站群短期发电优化调度计算量大,实际应用中为满足计算过程和结果可复现需求,多采用各类改进动态规划算法,求解速度难以满足需求。对此,结合大规模水电站群短期发电优化调度模型,同时给定起始状态和最终状态的特性,分析了从起始状态和最终状态同时进行求解的可行性,提出了改进的双向动态规划并行解算方法,实例计算表明,应用此方法可使大规模流域水电站群短期发电优化调度计算速度提高一倍。研究成果可供类似工程参考。

Improvement of Short-Term Generation Optimal Scheduling Algorithm for Large-Scale Hydroelectric Power Plants

Short-term optimal generation scheduling of large-scale hydroelectric power plants needs large amounts of computation. Generally, various improved dynamic programming algorithms are used to solve the problem for the reproducibility of calculation process and results. However, the computation speed is undesirable. Thus, with the starting state and final state given, the feasibility and method of bi-directional dynamic programming has been researched. With a case study, the proposed algorithm has been proved to promote the calculation by one time faster. The achievement can be referenced by other similar projects.
