Abstract

The present invention provides a reservoir regulation method based on large scale system theory time and space decomposition and coordination. The method comprises the following steps of: (1) for generation and water supply targets, performing space decomposition of a complex system; (2) for the generation and water supply targets, performing further time decomposition of the system; (3) taking aLagrangian function of a sub system as a target function of the sub system, writing out a constraint condition of the sub system; (4) establishing a coordination-level optimization algorithm; and (5)performing determination of a condition of convergence. The reservoir regulation method based on the large scale system theory time and space decomposition and coordination performs coupling of the space decomposition technology and the time decomposition technology and performs processing for features when the space decomposition technology and the time decomposition technology are subjected to each benefit objective application so as to further improve the reliability and the feasibility of application of the large scale system hierarchical control and decomposition and coordination theory in the reservoir group optimization dispatching and promote the development of the reservoir dispatching.

Description

technical field [0001] The invention belongs to the technical field of optimal dispatching of reservoirs, in particular to a reservoir dispatching method based on time and space decomposition and coordination of large system theory. Background technique [0002] In the study of optimal dispatching of reservoir groups, since the dynamic programming method has less restrictions on the objective function and constraints, it can obtain the optimal solution in the full dispatching period and has been widely used at home and abroad. However, there is a problem of "curse of dimensionality" in dynamic programming. In this regard, it is an effective way to apply the principle of hierarchical control and decomposition coordination of large-scale systems to optimize the scheduling of storage groups. [0003] Large-scale system hierarchical control and decomposition coordination technology decomposes a large-scale system with many decision variables, complex objective functions and con...
