The risk of water flow compensation caused by the additional discharge of leading hydropower station has increased the difficulty of multi entity cascade hydropower optimal operation, and the backwater jacking effect of downstream hydropower stations has further increased the complexity of the model. Therefore, non-linear modeling is carried out for the flow compensation process of leading hydropower station, and the risk of flow compensation in the compensation period and the recharge period is quantified. At the same time, the impact of backwater jacking effect of downstream hydropower stations on the tail water level of leading hydropower station is considered, and then a scheduling model with the goal of maximizing the joint operation revenue of cascade hydropower stations is constructed. The analysis of the example shows that the method can more reasonably distribute the benefits between the upstream and downstream hydropower stations in the cascade basin, coordinate the conflicts of interests among the multi entity cascade hydropower stations, and improve the activity of the hydropower stations at all levels in participating in the market scheduling.

龙头电站增发流量引发的水流补偿风险增加了多主体梯级水电优化调度的难度,且下游电站回水顶托效应进一步加剧了模型的复杂度。为此,针对龙头电站的水流补偿过程进行非线性建模,对补偿期与回蓄期水流补偿风险进行量化处理,同时考虑下游电站回水顶托效应对龙头电站尾水位的影响,进而构建了以梯级电站联合运行收益最大为目标的调度模型。算例分析表明,该方法能够更加合理地对梯级流域上下游电站之间进行效益分配,协调了多主体梯级水电站之间的利益冲突,提高了各级电站参与市场调度的活跃度。

龙头电站增发流量引发的水流补偿风险增加了多主体梯级水电优化调度的难度,且下游电站回水顶托效应进一步加剧了模型的复杂度。为此,针对龙头电站的水流补偿过程进行非线性建模,对补偿期与回蓄期水流补偿风险进行量化处理,同时考虑下游电站回水顶托效应对龙头电站尾水位的影响,进而构建了以梯级电站联合运行收益最大为目标的调度模型。算例分析表明,该方法能够更加合理地对梯级流域上下游电站之间进行效益分配,协调了多主体梯级水电站之间的利益冲突,提高了各级电站参与市场调度的活跃度。

The risk of water flow compensation caused by the additional discharge of leading hydropower station has increased the difficulty of multi entity cascade hydropower optimal operation, and the backwater jacking effect of downstream hydropower stations has further increased the complexity of the model. Therefore, non-linear modeling is carried out for the flow compensation process of leading hydropower station, and the risk of flow compensation in the compensation period and the recharge period is quantified. At the same time, the impact of backwater jacking effect of downstream hydropower stations on the tail water level of leading hydropower station is considered, and then a scheduling model with the goal of maximizing the joint operation revenue of cascade hydropower stations is constructed. The analysis of the example shows that the method can more reasonably distribute the benefits between the upstream and downstream hydropower stations in the cascade basin, coordinate the conflicts of interests among the multi entity cascade hydropower stations, and improve the activity of the hydropower stations at all levels in participating in the market scheduling.
