Short-Term Optimal Operation of Banduo Reservoir in the Source of Yellow River

针对黄河源区班多水库尚缺乏指导其运行的具体的调度方案，且存在防凌期库面易结冰、丰水期有大量弃水、枯水期发电量急剧下降等问题，本文对班多水库分别建立了不同典型日、周调度的短期定出力常规调度模型和发电量最大优化调度模型，采用遗传算法求解优化调度模型。通过对比常规与优化的日、周调度中发电量、弃水及出力等结果，短期优化调度减少了弃水量，增加了发电量；获得了班多水库初步运行方式，揭示了班多水库的最优运行规律。研究发现：班多水库的周调度较日调度结果更为理想，具有周调节潜力。研究成果可用于指导班多水电站不同时期的运行调度，可提高水资源利用效率和发电企业的经济效益。 Banduo reservoir, located in the source area of the Yellow River, is lack of specific operation schemes. There are many problems such as the freezing of the reservoir surface during the ice prevention period, the large amount of abandoned water in flood season and the drastic decrease of the power generation in dry season. In this paper, the short-term conventional operation model of constant output and the operation model of maximal power generation optimized by the genetic algorithm were established under daily and weekly periods. By comparing the power generation, abandoned water and output in different periods, it is found that the short-term optimal operation reduces the amount of abandoned water and increases the power generation. Initial operation mode of Banduo reservoir is obtained and optimal operation rules are derived. Banduo reservoir has the potential of weekly operation since the weekly results are better than the daily’s. This study can guide the actual operation of Banduo hydropower station in different periods, which can improve water resources utilization and economic benefit of power generation enterprises.
