摘要：

Short-term operation of hydropower stations is a vital part of power grid scheduling. In order to ensure security and stability of power grid, it is of great importance for stations to operate according to the power grid instructions. Yet as far as stations concerned, they'd Iike to run as an economical way so that the maximal benefit is reaped. To satisfy the demand of power system and optimize the operation of cascade hydropower stations at the same time, a daily joint optimization model of cascade hydropower stations is established, considering the daily power load curve and power generation of a single station. Then a heuristic hierarchie optimization (HHO) strategy is proposed to solve the model. The total hydroenergy consumption of single and joint operation of cascade hydropower stations of Qingjiang River is calculated. The results make clear that comparing with single operation, the hydroenergy consumption of joint operation is less, which is of great significance to cascade hydro power stations. The modeling and solution can be good references to cascade hydropower stations dispatched by the same power grid.
