水库生态-发电优化调度及应用研究

近年来，随着河流生态环境问题的凸显和可持续发展理念的深入与普及，考虑河道生态的水库优化调度研究越来越受到关注。结合海南省牛路岭水库一库两站联合调度问题，分析确定了适宜、次小、最小三种生态需水量，建立了牛路岭一库两站生态-发电优化调度模型，并开发了求解该模型的遗传算法程序。针对丰、平、枯三种典型年份，通过优化调度计算，得出了不同年份各种生态需水量情况下的发电效益值，并将其与牛路岭水库现状调度结果进行了比较，同时分析了河道生态需水对发电效益的影响。结果表明，本优化调度模型在兼顾河道生态需水的基础上，可明显增加牛路岭水库的总发电量。本研究既为牛路岭一库两站联合调度提供技术支持，又可为类似问题的研究提供借鉴。

Reservoir Ecological - power Optimal Operation and Application Research

In recent years, with emerge of river ecological environmental problems and widely acceptance of the idea of sustainable development, more attentions are taken on reservoir optimal operation combined with the river ecological water demand. An ecological- power optimal operation model for Niululing Reservoir system which contains a reservoir and two power stations was developed and three kinds of ecological water demands (the minimum, the second minimum and proper) were analyzed and determined. Accordingly, genetic algorithm program was developed to solve the model. By employing the model and program, respective generation benefits of the power stations under the three kinds of ecological water demands in three typical years(water-rich, water-normal and water- shortage)were calculated. Then, the benefits were compared to the contemporary operation results of the Reservoir, and the impacts of river ecological water demands on power generation were analyzed. The results reveal that, this model can increase the generated energy distinctly taking account of the river ecological water demands. The research provides both technical support for Niululing Reservoir operation and practical reference for similar studies.
