Abstract

The invention belongs to the technical field of renewable energy source hydrogen production, and particularly discloses a capacity configuration method of a coupled wind-solar complementary optimization series-parallel hydrogen production system. A capacity configuration model of the coupled wind-solar complementary optimization series-parallel hydrogen production system is constructed by taking the maximization of the periodic hydrogen production amount as a first objective function, the minimization of the initial investment cost as a second objective function and the minimization of the electricity abandoning rate as a third objective function; determining an initial Pareto optimal solution set of the capacity configuration model through sequential target optimization; selecting a main objective function, converting other objective functions except the main objective function into augmented constraint conditions based on the extreme values of Pareto optimal solutions of different objective functions in the initial Pareto optimal solution set, and updating the Pareto optimal solution set of the capacity configuration model by adopting an augmented epsilon-constraint method; and optimizing the capacity configuration of the system based on the updated Pareto optimal solution set. According to the invention, reasonable planning of the capacity configuration of the hybrid hydrogen production system is realized.
