| 摘 要： | 针对梯级水电站 “汛期弃水保防洪、枯期少水发电少”、不能最大化开发利用水资源的问题，提出新增混合式抽水蓄能机组的梯级水电站中长期优化调度策略。建立在丰平枯分期电价下，以年发电效益最大为目标函数的模型，用自适应水位廊道法解耦梯级复杂联系的约束条件，逐步优化算法求解。通过仿真验证得到，新增抽水蓄能机组能提高梯级的整体发电收益，丰水年减少弃水，增加枯期电量，为最大化利用水资源改善梯级水量分配提供新思路。

| Abstract: | Targeting the problems faced by cascade hydropower stations， such as “abandoned water and flood protection in flood season， less water and electricity generation in dry season”， and not being able to maximize the development and utilization of water resources， the paper proposes the medium and long term optimal scheduling strategy of the cascade hydropower stations with new hybrid pumped-storage units. The model with the objective function of maximizing annual power generation benefits is established， and adaptive water level corridor method is used to decouple the constraint conditions of cascade complex relations， gradually optimizing the algorithm. The simulation results show that the new pumped-storage units can increase the overall power generation income of the cascade， reduce the abandoned water in a high-flow year， and increase the electricity in a dry season， providing a new idea for the maximum utilization of the water resources and the improvement of the cascade water distribution. |
