Capacity Optimization Allocation Method of Electro-Hydrogen Coupling System Considering the Multiple Utilization of Hydrogen Energy Characteristics

Hydrogen energy，as a clean energy source，can be combined with renewable energy such as wind energy to provide low-carbon operation solutions for the system. First，on the basis of the traditional electro-hydrogen coupling system，this paper introduces natural gas and carbon capture system，and proposes an optimal configuration model method for electro-hydrogen energy system considering the characteristics of multiple utilization of hydrogen energy. Then，a system model combining the two application approaches of hydrogen energy zero-pollution power generation and methanation is established， and the improved particle swarm optimization algorithm is proposed to optimize and solve the construction model with the annual cost of the system as the objective function，so as to obtain the optimal capacity configuration scheme of each equipment in the system. Finally，the comparative analysis of the example shows that the optimization scheme increases the disposable carbon quota when the cost is the lowest，which is environmentally friendly.
