joint operation and dynamic control of flood limiting Water levels for mixed cascade reservoir systems
Journal of Hydrology, 2014Co-Authors: Yanlai Zhou, Chongyu XuAbstract:Summary Reservoirs are one of the most efficient infrastructures for integrated Water Resources Development and management; and play a more and more important role in flood control and conservation. Dynamic control of the reservoir flood limiting Water level (FLWL) is a valuable and effective approach to compromise the flood control, hydropower generation and comprehensive utilization of Water Resources of river basins during the flood season. The dynamic control models of FLWL for a single reservoir and cascade reservoirs have been extended for a mixed reservoir system in this paper. The proposed model consists of a dynamic control operation module for a single reservoir, a dynamic control operation module for cascade reservoirs, and a joint operation module for mixed cascade reservoir systems. The Three Gorges and Qingjiang cascade reservoirs in the Yangtze River basin of China are selected for a case study. Three-hour inflow data series for representative hydrological years are used to test the model. The results indicate that the proposed model can make an effective tradeoff between flood control and hydropower generation. Joint operation and dynamic control of FLWL can generate 26.4 × 10 8 kW h (3.47%) more hydropower for the mixed cascade reservoir systems and increase the Water resource utilization rate by 3.72% for the Three Gorges reservoir and 2.42% for the Qingjiang cascade reservoirs without reducing originally designed flood prevention standards.

joint operation and dynamic control of flood limiting Water levels for cascade reservoirs
Water Resources Management, 2013Co-Authors: Jionghong Chen, Yu Li, Yanlai ZhouAbstract:Reservoirs are among the most effective tools for integrated Water Resources Development and management. The dynamic control of reservoir flood limiting Water level (FLWL) is a valuable and effective method to compromise the flood control and conservation for reservoir operation during the flood season. This paper focuses on joint operation and dynamic control of FLWL for cascade reservoirs. A composition and decomposition-based model that consists of an aggregation module, a storage decomposition module and a simulation operation module was developed. The model was applied to the Qingjiang basin in south of China using the 3-hour inflow data series for representative hydrological years. Application results indicate that the proposed model can make an effective tradeoff between the flood control and hydropower generation. Joint operation and dynamic control of FLWL can increase power production by 4.51 % (1.79 × 10 8 kWh) and increase Water use rate by 2.73 %. It can enhance benefits of the Qingjiang cascade reservoirs without compromising flood prevention objectives. Copyright Springer Science+Business Media Dordrecht 2013

optimal design of seasonal flood limited Water levels and its application for the three gorges reservoir
Journal of Hydrology, 2015Co-Authors: Pan Liu, Shenglian Guo, Lihua Xiong, Wang Zhang, Jingwen ZhangAbstract:Summary Reservoirs perform both flood control and integrated Water Resources Development, in which the flood limited Water level (FLWL) is the most significant parameter of tradeoff between flood control and conservation. This study was aimed at developing the varied seasonal FLWL to obtain more economic benefits without decreasing the original flood prevention standards. The Copula function was used to build the joint distribution of seasonal floods, which clarified the relationship between the frequencies of the seasonal flood quantiles and those of the annual maximum. A constraint was then established to meet the requirement that the total flood risk of the seasonal FLWL should be less than that of the original FLWL. The seasonal FLWL can optimally be determined because numerous schemes of seasonal design floods are able to satisfy a given flood prevention standard. As a result, a simulation-based optimization model was proposed to maximize multiple benefits, such as flood control, hydropower generation and navigation. Using the case study of the China’s Three Gorges Reservoir (TGR), the proposed method was demonstrated to provide an effective design for the seasonal FLWL, which decreases a slight FLWL for the main flood season to largely increase the FLWL of the pre-flood and post-flood seasons. The optimal designed seasonal FLWL scheme involves tradeoffs among flood control, hydropower generation and navigation, and enhancement of the economic benefits without increasing the flood risk.
