Abstract

The invention discloses a reservoir optimization scheduling method considering the correlation and randomness of water supply and demand process. The one-dimensional random process of runoff or water demand is analyzed from two aspects: the randomness of the random variables and the correlation of variables between adjacent time periods, and the state transition probability matrix is ​​used to characterize the correlation characteristics between different states of the two random variables; Step 3: Analyze the runoff and water demand Correlation and randomness of multi-dimensional processes; Step 4: Realize a stochastic dynamic programming method oriented to the correlation and randomness of multi-dimensional processes. The invention takes the randomness and correlation of the two-dimensional process of water supply and demand into consideration, and carries out the optimization and scheduling of the stochastic reservoir, which can effectively solve the problem of the correlation and randomness of the water resources supply and demand process in the water supply scheduling of the reservoir.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering, and particularly relates to a reservoir optimization scheduling method considering the correlation and randomness of the supply and demand process of water resources. Background technique [0002] As the core non-engineering measure for reservoir control, reservoir revitalization dispatch aims to solve deterministic or stochastic optimization using optimization methods on the premise of ensuring the safety of reservoir engineering and downstream flood control objects according to reservoir development tasks and comprehensive utilization requirements. Scheduling model, formulate reservoir storage and discharge rules, meet the water demand of various water-using departments to the maximum extent, and achieve a high degree of matching between the supply process and the demand process of water resources. [0003] As one of the methods to solve the medium and long-term stochastic...
