Multi-Reservoir System Operation Theory and Practice

Abstract

The state-of-the-art on operation of multi-reservoir system is reviewed and multi-reservoir construction and management practice in China are introduced at the beginning. Considering the impact of human activity on the reservoir inflow, multi-reservoir operation is studied within theory framework of dualistic water cycle. The reservoir operation rule form and derivation method are the most important elements for deriving optimal multi-reservoir operation policy. Different rule curves and multi-objective optimization algorithms are discussed in this chapter. Inter-basin water transfer project becomes one of effective measures to mitigate imbalance between water supply and water demand. The multi-reservoir operation problem in inter-basin water transfer project is illustrated mainly on deriving the water transfer rule and water supply rule using bi-level model. Reservoir inflow is important information for multi-reservoir operation. The effect of inflow forecast uncertainty on real-time reservoir operation, effective forecast horizon identification and generalized marginal model of the uncertainty evolution of inflow forecast are discussed in details.
