梯级水电站发电调度保证出力动态规划Cascade Hydropower Station Power Dispatching Guaranteed Output Dynamic Programming

摘要:

以金沙江下游溪洛渡–向家坝梯级水电站为对象,开展不同保证出力对梯级年发电调度的影响研究。首先以梯级年发电量最大为目标构建优化调度模型,进而将两电站保证出力转化为最小出力约束条件,采用动态规划法对模型进行求解。实例计算结果表明,当上游溪洛渡电站保证出力不变时,增大向家坝电站保证出力,则溪洛渡电站的年发电量不变,而向家坝电站以及梯级年发电量减小;当下游向家坝电站保证出力不变时,增大溪洛渡电站保证出力,则溪洛渡电站的年发电量减小而向家坝电站增大,梯级年发电量减小;不同保证出力对梯级最优调度过程的影响主要体现在汛前1~6月份,而在7~12月份保持不变。

The influence of different guaranteed output on annual generation dispatching of the Xiluodu and Xiangjiaba cascade hydropower stations was studied. Firstly, the dispatching model targeting the maximum of annual cascade generation was built and solved by dynamic programming method with different guaranteed output constraints. The results show that when upstream Xiluodu’s guaranteed output is unchanged and Xiangjiaba’s guaranteed output increases, the annual power generation of Xiluodu will be unchanged, and the annual power generation of Xiangjiaba and the cascade stations will decrease. When downstream Xiangjiaba’s guaranteed output is unchanged and Xiluodu’s guaranteed output increases, the annual power generation of Xiluodu will decrease and Xiangjiaba will increase, the cascade stations will decrease. Effects of different guaranteed output on optimal scheduling of cascade process are mainly reflected in the flood season from January to June, while it remains unchanged from July to December.
