Bi-layer Optimization of integrated wind-PV-hydrogen systems considering the whole life cycle

In order to solve the problem of coordinated optimal configuration and scheduling of individual devices in a coupled wind-PV-hydrogen power generation system, A Bilayer optimisation model is proposed. The upper model is a planning model that targets full life cycle economic indicators. The lower layer is a dispatch model that targets brother you power purchases, energy and hydrogen abandonment. By iterating, Determine the optimal capacity and optimal output of the equipment. Secondly, the particle swarm algorithm is used to solve the upper optimal configuration model and the lower optimal scheduling model is solved using the Yalmip toolbox Cplex commercial solver for the MATLAB platform. Finally, the validity of the configuration results is verified through a park as an arithmetic example, which provides theoretical support for the economic operation of wind-hydrogen coupled power generation system.
