水库和泵站群的多目标联合调度研究 Multi-Objectives Joint Operation of Reservoirs and Pumping Stations

为了验证设计报告中设计值的合理性及初拟运行方式的可行性，提高水资源利用效率，本文以引汉济渭工程调水区黄金峡水库和三河口水库及其泵站群为研究对象，建立了兼顾调水量最大与梯级发电量最大的多目标优化调度模型，采用NSGA-II求解模型。同时，为了凸显优化模型的优越性，建立求解了常规调度模型作为对照模型。通过模型分析计算，论证了设计值的合理性，揭示了初拟调度运行方式的可行性。结果表明：多目标联合优化调度提高了径流利用程度和利用效率，显著增加了调水量和发电量。研究成果获得调水区水库群不同典型年的多目标均衡解，为引汉济渭调水区水库群及其泵站的运行提供了技术支撑，为实现水库群多目标运行调度提供理论依据。 To verify the rationality of the design value in the design report and improve the water use efficiency, the feasibility of the preliminary operation mode, the Huangjinxia and Sanhekou reservoirs and pumping stations of the water diversion project from the Han to the Wei River were selected as the targets in this paper. Multi-objective joint operation model with the largest amount of water transfer and the maximum power generation is established and solved by NSGA-II. To highlight the advantages of optimizing the model, conventional operation model was established as a comparison model. Moreover, reasonability of design value is certified and feasibility of the initial operation rule is revealed by model analysis and calculation. Results showed that the multi-objective joint operation improved the runoff utilization efficiency and increased the amount of water and power generation. Achievements obtained multi-objective equilibrium solution of reservoirs with different typical years, which provided a technical support for the operation of reservoirs and pumping stations, and provided the theoretical basis for reservoirs multi-objective operation.
