【摘要】：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。
[Abstract]:In order to meet the demand of the calculation process and results, many kinds of improved dynamic programming algorithms are used in practical application, and the solution speed is difficult to meet the demand. Combined with the short-term optimal dispatching model of large scale hydropower stations and given the characteristics of the initial and final states, the feasibility of simultaneously solving the initial state and the final state is analyzed. An improved parallel solution method for bidirectional dynamic programming is proposed. The application of this method can double the calculation speed of short-term optimal dispatching of large scale hydropower stations in river basins, and the research results can be used as a reference for similar projects.
