Abstract
In order to improve the influence of wind curtailment on waste of electric power resource, we preliminarily analyzed the feasibility of natural gas networks under hydrogen injection from a wind farm by evaluating the ability of networks on storing injected hydrogen. Based on the analytical model coupled with wind power generation, hydrogen production from electrolysis of water and calculation on natural gas networks, we performed steady and unsteady simulation analysis of hydrogen storage in gas networks to evaluate the feasibility of this method. Two strategies, constant-pressure-variable-flow model and variable-pressure-constant-flow model, are proposed to satisfy energy needs of user nodes. According to the results of the steady simulation, both of the two strategies could achieve the aim of hydrogen storage in networks and decrease the consumption of natural gas of user nodes. Because results of steady simulations shows that the variable-pressure-constant-flow model has advantages on saving natural gas, a strategy for dynamic adjustments on input points of supply is proposed. Results of unsteady simulations show that this strategy can basically fulfill the needs of user nodes. Through analysis, the variable-pressure-constant-flow strategy could not only meet the energy requirement of user nodes, but also help to decrease the consumption of natural gas in networks, which promotes the energy conversion between electricity from wind curtailment and hydrogen energy in the networks, and provides references for similar power plants.关键词
