Long-term scheduling of large cascade hydropower stations in Jinsha River, China

Energy Conversion and Management, 2015
The Jinsha River is the third longest river in the world. It consists of four large hydropower stations with total installed capacity 42,960 MW lying on the upper stretches of the Yangtze River, which is the longest river in the word. Due to the great potential of large cascade hydropower stations on power generation, long-term scheduling of large ...

Optimization Scheduling of Cascade Hydropower Stations in Energy Conservation and Emission Reduction

Advanced Materials Research, 2013
Considerable water saving and electricity can be attained by optimal regulation of cascade hydropower plants, equivalent to building large and medium-sized hydropower stations without increase in investment and immigration. Thus, the optimal regulation of cascade hydropower plants has great significance on increasing the consumption ratio of fossil ...
