Abstract:

To increase the share of the hydroelectric power in total energy supply is important way to perform the promise of our government to international

society about energy conservation and emission reduction. By the optimized dispatch of the basin cascade hydropower stations, the generated electricity of

these hydropower stations can increase considerably, which is equivalent to that to build some large or medium-size hydropower stations without needs to

increase the investment and to migrate the residents. These measures are of important significance for increasing the consumption proportion of non-fossil

energy and decreasing the atmospheric pollutant emission.

Key words: cascade hydropower stations, optimized dispatch, reduce water consumption and increase generated electricity, energy conservation and emission reduction
