A smart matching layered coupling method and system for cascade reservoir group joint dispatching

Abstract

The present invention proposes a cascade reservoir group joint scheduling intelligent matching layered coupling method and system. By setting necessary calculation parameters, the discharge flow of the power station at different times is used as a decision variable for serial coding; the population is initialized in the search space; through the penalty function Calculate the fitness value of all individuals in the population using the method; update the global optimal position of the population and the optimal position of the individual history; use the arccosine algorithm to update the individual position in the population; perform boundary check on the individual position in the current population; through iterative calculation until reaching the maximum iteration of the population The number of times; the global optimal position of the current population is used as the optimal dispatching process of the cascade power station. In this way, using the method of the present invention to solve the joint scheduling problem of cascade reservoirs has simple principles, strong robustness, high search efficiency, and fast convergence speed, which can effectively avoid falling into local optimum, and finally achieve the purpose of improving the power generation efficiency of the entire cascade power station. Reservoir power generation scheduling provides a scientific basis.

Description

A layered coupling method and system of intelligent matching for joint dispatching of cascade reservoir groups technical field The present invention belongs to cascade reservoir group power generation dispatching field, more specifically, relate to a kind of cascade reservoir group joint dispatching Intelligent matching hierarchical coupling method and system. Background technique [0002] As a united whole, cascade reservoirs have the benefits of storage capacity compensation, hydrological compensation and electric power compensation. Cascade water The long-term optimal scheduling in the database is an optimization problem in which the operation mode of the power station is determined for a long period of time (such as quarterly and yearly). because Due to the long period of time, during the dispatch period, it is mainly affected by the uncertain natural water supply and the power station's own adjustment ability. For example, on the same day However, the distributi...
