梯级水库联合优化调度模型及其应用

Model of Joint Optimizing Operation for Cascade Reservoirs and Application

为充分挖掘梯级水库间的水文补偿和库容补偿潜力,获取更高的综合利用效益,提出应用判别系数与水库蓄供水控制线相结合的方法,并结合免疫粒子群算法,以梯级电站发电量最大为目标,对水库蓄供水控制线进行优化。以乌江梯级水库为例,对其蓄供水方式进行了研究。联合调度结果表明,优化后的水库蓄供水控制线不仅可以合理控制水库蓄放水次序和蓄放水量,达到合理控制水库群运行方式的目的,而且在实际调度中具有良好的可操作性和抗风险性。

In order to fully dig potentials of hydrological and reservoir capacity compensation between cascade reservoirs and achieve higher comprehensive utilization benefit, this article proposes to optimize water storage and supply control line by method of combining discriminant coefficient with water storage and supply control line, together with immune particle swarm algorithm and with target of maximizing power generation of cascade reservoirs. Taking Wujiang River Cascade Reservoir as example, it researches into water storage and supply mode, combining with dispatching result showing that optimized water storage and supply control line of reservoirs can not only properly control order and volume of water storage and discharge of reservoirs to achieve the target of properly controlling operation mode of reservoirs cluster, but also show fine operability and anti-risk capacity in real dispatching.
