摘要
水库群防洪优化调度通过合理安排水库群的蓄泄水量,最大程度减轻洪水灾害。针对水库群防洪调度目标难以分解以及“维数灾”等问题,构建基于最大削峰准则的水库群防洪优化调度模型,利用轮库法有效降低维度并结合粒子群智能算法优化求解。以黄河花园口以上干支流的5座大型水库组成的混联水库群为例,开展典型年水库群联合优化调度,结果表明:相较于常规调度,优化调度方案能够削减防洪控制点的洪峰流量,平稳泄流过程,提高控制性水库的防洪可靠性,大大减轻黄河下游的防洪压力。
The optimal flood control operation of reservoir groups aims to achieve effective water disaster prevention and provide a reference for real⁃time flood control decision⁃making.Aiming at the issues of difficulty in decomposing flood control targets and“dimensional disaster”in calculation,an optimal flood control dispatching model for mixed⁃linked reservoirs group based on the maximum peak shaving criterion was built.Utilizing the round⁃robin method effectively reduced dimensionality and combined with particle swarm optimization algorithm for efficient solution optimization.Taking the example of a mixed⁃connected reservoir group composed of five large reservoirs on the upper reaches of Huayuankou section of the Yellow River,a joint optimization scheduling of the reservoir group was conducted for typical years.The results indicate that compared to conventional scheduling,the optimized dispatching scheme effectively deduces the optimal solution.It reduces peak flow at flood control points and stabilizes the flow discharge process.Additionally,it enhances flood control reliability of controlling reservoirs and significantly alleviates flood control pressure of the Lower Yellow River.
