However,when the SDP is applied to the optimal operation of multi-reservoirs system with multi-annual regulating reservoirs,the problems of "curse of dimensionality" will be aroused and the characteristic of uncertain regulated cycles can t be showed.

Stochastic Dynamic Programming (SDP) is a basic method to achieve optimal operation of reservoir, while which is applied to multi-reservoir containing multi-annual regulating reservoir with characteristic of unregulated cycle, the problem of the "curse of dimensionality" will be aroused and the characteristic of multi-annual regulating reservoir can t be showed.

Study on the water level at the end of year for carryover storage reservoir;

Research on the relations between the regulating storage volume and economic benefits of pumped-storage station;

This paper took Xiniutan reservoir reinforcement as a example,discussed how to use pluriennal regulation methods to calculate the quantity of runoff and irrigation,and defined irrigation storage capacity in the end.

Based on the observation data of seepage quantity obtained from the dam of a annual storage reservoir and that of a pumped storage power station,the regularities and characteristic values are analyzed,the statistical model and regression model are established,and the affecting components are calculated by quantitative analysis.
