跨省跨流域水电站群发电优化调度已成为中国大水电系统调度运行的瓶颈问题，以南方电网水电站群为背景，结合其长期优化调度问题，提出水电长期可吸纳电量最大模型。该模型在发电量最大模型基础上，将电网对水电的吸纳能力和受送电量限制作为控制条件，以适应大规模水电站群优化调度的实际需要，结合逐步优化算法、离散微分动态规划算法和逐次逼近算法求解。以南方电网92座水电站组成的水电站群系统为背景的实例研究表明，该模型体现了省级电网间长期受送电需求和限制，能有效解决大规模跨电网受送电模式下的长期水电调度问题。

The optimal operations for hydropower systems covering multi provinces and multi basins have become bottlenecks of large scale hydropower system of China. A long term optimal operation model for absorbed energy maximization of hydropower systems was proposed for the hydropower system of China southern power grid （CSG）. Based on the energy maximization model, absorbing capacity of power grids and limitation of electric transmission among interconnected power grids were involved in the model to meet the real operation demands of large scale hydropower operations. Progressive optimality algorithm, discrete differential dynamic programming and successive approximation method were combined to solve the model. Case study for a 92 hydropower plants system of CSG shows that the model can satisfy the requirements and confines about long term energy transmission inter provincial power grids, and is suitable for long term hydropower operation problems with large scale inter grids power transmission.
