Modeling, Optimization and Evaluation of Production-storage-utilization Hydrogen System Based on Renewable Energy

To solve the problem of wind and solar abandonment in Northwest China and promote the development of green and low-carbon energy transformation, large-scale renewable energy hydrogen production technology is taken full account when constructing the production-storage-utilization hydrogen system in this paper. Besides, a balance optimization model is also proposed to quantitatively evaluate the consumption space, consumption capacity and application benefits of hydrogen in various fields (especially in the field of power system). By using CPLEX solver and time series production simulation method, the proposed model can be solved effectively and comparative analysis of different cases can be conducted in detail. Simulation results show that power curtailment of renewable energy generation can be utilized to produce hydrogen, which contributes to the improvement of energy efficiency and economic benefit.
