Description

China’s gross installed hydropower generating capacity has surged 500% since 1980 and exceeded 100 GW in 2004, making up one quarter of gross installed electric power capacity and providing about e 20 percent of the country’s total electric power. China’s hydropower system, after nearly 20 years development, has formed a trans-basin, large-scale hydropower stations operation system, with complex scheduling relations and requiring a variety of methods and techniques to solve. One of the biggest challenges facing power grids of China today is how to construct a large scale operation hydropower system which is scientific, efficient, convenient, and available for practical system. The paper is a summary of the outcome of the decision support system for large-scale hydropower system operations oriented to provincial or municipal power grids. The background, objectives, challenges and contents of the decision support system are presented. The main focus is on the key technologies to the system, the design of the flowchart and its core components. The current system has been applied to the hydropower systems in the South China Grid Company, the East China Grid Company, the Fujian Province Power Grid, the Yunnan Province Power Grid and the Guizhou Province Power Grid, where the total of hydropower installed generation capacity has exceeded 30 GW at the end of 2009 and a total of 1500 hydropower stations. Some techniques are also beneficial for other systems.

Decision Support System for Large-Scale Hydropower System Operations

China’s gross installed hydropower generating capacity has surged 500% since 1980 and exceeded 100 GW in 2004, making up one quarter of gross installed electric power capacity and providing about e 20 percent of the country’s total electric power. China’s hydropower system, after nearly 20 years development, has formed a trans-basin, large-scale hydropower stations operation system, with complex scheduling relations and requiring a variety of methods and techniques to solve. One of the biggest challenges facing power grids of China today is how to construct a large scale operation hydropower system which is scientific, efficient, convenient, and available for practical system. The paper is a summary of the outcome of the decision support system for large-scale hydropower system operations oriented to provincial or municipal power grids. The background, objectives, challenges and contents of the decision support system are presented. The main focus is on the key technologies to the system, the design of the flowchart and its core components.
