Abstract

The invention discloses a multi-objective optimization configuration method and system for a wind-light-hydrogen storage system and a storage medium, and the method comprises the steps: constructing an objective function with the lowest total cost and the minimum system load power shortage rate, taking the power and capacity limitation of the system as constraint conditions, and taking the operation number of each device in the system as a decision variable; performing population initialization on the wind-light-hydrogen storage system model; performing non-dominated sorting on the initial population through a non-dominated genetic algorithm with an elitist strategy, and obtaining a first generation of offspring population through selection, crossover and mutation operations; from the second generation, combining the parent population with the child population, performing non-dominated sorting on the combined population, performing crowding degree calculation on individuals in each non-dominated layer, and selecting the individuals to form a new parent population according to a non-dominated relationship and the crowding degree of the individuals; performing selection, crossover and mutation operation on the new parent population; and outputting a capacity optimization configuration scheme when the maximum number of iterations is reached. According to the invention, the problem of optimal configuration in a complex scene can be solved.

Description

technical field [0001] The invention belongs to the technical field of optimal configuration of new energy power generation systems, and specifically relates to a multi-objective optimal configuration method, system and storage medium of a wind-solar hydrogen storage system. Background technique [0002] In the context of the "double carbon" requirements, my country is vigorously developing new energy power generation to achieve energy conservation and emission reduction in the power industry. However, the power generation of new energy sources such as wind and solar fluctuates greatly with seasons and environmental factors, so it is necessary to integrate energy storage equipment to build a coupling system with high stability, high economy, and low carbon emissions. [0003] Among various energy storage technologies, hydrogen energy storage has the advantages of large energy storage capacity, long storage time, cleanliness and pollution-free, and is more competitive in the ...
