An adaptive optimization method and system for power generation scheduling of a cascade hydropower system

Abstract

The invention discloses an adaptive optimization method and system for power generation scheduling of a cascade hydropower system. The method comprises the steps of determining a constraint conditionset of each hydropower station; Setting calculation parameters and generating an initial population; Calculating the individual fitness and updating the historical position of the individual and the global optimal position of the population; Updating the position of each individual by adopting a standard sine-cosine algorithm; Adopting a population position center variation strategy to increase individual diversity, introducing a neighborhood search strategy to improve population global optimization capability, and utilizing a simplex dynamic search strategy to enhance algorithm convergence speed; And continuously updating the position of each individual through multi-round iteration, and taking the population global optimal position obtained in the last round as an optimal scheduling process. The Yangtze River basin engineering application result shows that the method has the advantages of being high in calculation precision, high in optimizing speed, high in searching capacity, highin robustness and the like, the overall power generation benefit of the cascade hydropower system can be remarkably improved, and the method has important engineering application value.

Description

technical field [0001] The invention belongs to the field of efficient utilization of water resources and optimal dispatching of hydropower station groups, and more specifically relates to an adaptive optimization method and system for power generation dispatching of a cascade hydropower system. Background technique [0002] In recent years, my country's economy has developed rapidly, and my country's water conservancy has gradually transformed from the stage of large-scale construction to a new stage of joint dispatching, operation, management and maintenance. Cascade hydropower system power generation scheduling can make full use of hydropower resources and increase power generation efficiency, which is very important to achieve the sustainable development and energy conservation and emission reduction goals of the national strategy. The cascade hydropower system usually hopes to maximize the total power generation of the cascade hydropower system under the condition of me...
