Reservoir optimization scheduling method considering relevance and randomness of water resource supply and demand process

Abstract

The invention discloses a reservoir optimization scheduling method considering relevance and randomness of a water resource supply and demand process, and the method specifically comprises the following steps: 1, building a reservoir optimization scheduling model, and determining an optimization target and a constraint condition; 2, analyzing a runoff or water demand one-dimensional random process from two aspects of randomness of variables in a fixed time period and relevance of variables between adjacent time periods, and representing relevance characteristics between different states of every two random variables by adopting a state transition probability matrix; 3, analyzing relevance and randomness of the runoff and water demand multidimensional process; and 4, realizing a random dynamic planning method oriented to multi-dimensional process relevance and randomness. According to the method, randomness and relevance of the water resource supply and demand two-dimensional process are considered, random reservoir optimization scheduling is carried out, and the relevance and randomness problems of the water resource supply and demand process in reservoir water supply scheduling can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering, and in particular relates to a reservoir optimal scheduling method considering the relevance and randomness of the water resource supply and demand process. Background technique [0002] As the core non-engineering measure of reservoir control, reservoir prosperity dispatching aims to solve the deterministic or random optimization by using the optimization method under the premise of ensuring the safety of the reservoir engineering and the safety of downstream flood control objects according to the reservoir development tasks and comprehensive utilization requirements. The dispatching model formulates the rules for reservoir storage and discharge to meet the water demand of various water-using departments to the greatest extent, and achieve a high degree of matching between the supply process and demand process of water resources. [0003] As one of the methods to solve the ...
