In view of the fact that the reservoirs of medium and small hydropower stations usually operate at a lower level during the flood season because of the smaller regulating reservoir capacity, short decision time for flood regulation, maximum head of the unit and inundation limitation of the upstream reservoir area, etc., the flood resource utilization benefit is not fully utilized during the flood season regardless of the magnitude of the flood. The multi-objective risk analysis model for flood operation and scheduling of medium and small hydropower reservoirs is established with the objective of maximizing the power generation benefit and minimizing the flood risk, and the solution method for the optimal flood level is given when the forecasted incoming flood flow is in different ranges. The results show that when the reservoir faces different levels of floods, the optimal operation level can be obtained by coordinating the benefits and risks to increase the power generation benefits during small floods and reduce the flood losses during large floods, which provides a reference for the flood operation and scheduling of medium and small hydropower reservoirs under changing environment.

针对中小水电站水库在汛期调度运行过程中常常因为调节库容小、调洪决策时间短、机组最大水头和上游库区淹没限制等特点,而导致其汛期无论洪水量级大小常以较低水位运行造成洪水资源化效益得不到充分发挥的问题,重点考虑预报入库洪峰流量和预报误差不确定性的影响,以发电效益最大和防洪风险最小为目标,建立了中小水电站水库汛期运行调度多目标风险分析模型,并给出了当预报入库洪峰流量在不同范围时的汛期最优水位的求解方法。对龟都府水电站水库的验证结果表明,当水库面临不同量级的洪水时,通过效益和风险的协调可得到最优的运行水位,达到小洪水时增加发电效益和大洪水时减小洪灾损失的目的,为变化环境下中小水电站水库汛期运行调度提供了参考。

针对中小水电站水库在汛期调度运行过程中常常因为调节库容小、调洪决策时间短、机组最大水头和上游库区淹没限制等特点,而导致其汛期无论洪水量级大小常以较低水位运行造成洪水资源化效益得不到充分发挥的问题,重点考虑预报入库洪峰流量和预报误差不确定性的影响,以发电效益最大和防洪风险最小为目标,建立了中小水电站水库汛期运行调度多目标风险分析模型,并给出了当预报入库洪峰流量在不同范围时的汛期最优水位的求解方法。对龟都府水电站水库的验证结果表明,当水库面临不同量级的洪水时,通过效益和风险的协调可得到最优的运行水位,达到小洪水时增加发电效益和大洪水时减小洪灾损失的目的,为变化环境下中小水电站水库汛期运行调度提供了参考。

In view of the fact that the reservoirs of medium and small hydropower stations usually operate at a lower level during the flood season because of the smaller regulating reservoir capacity, short decision time for flood regulation, maximum head of the unit and inundation limitation of the upstream reservoir area, etc., the flood resource utilization benefit is not fully utilized during the flood season regardless of the magnitude of the flood. The multi-objective risk analysis model for flood operation and scheduling of medium and small hydropower reservoirs is established with the objective of maximizing the power generation benefit and minimizing the flood risk, and the solution method for the optimal flood level is given when the forecasted incoming flood flow is in different ranges. The results show that when the reservoir faces different levels of floods, the optimal operation level can be obtained by coordinating the benefits and risks to increase the power generation benefits during small floods and reduce the flood losses during large floods, which provides a reference for the flood operation and scheduling of medium and small hydropower reservoirs under changing environment.
