为评估利用风力发电的富裕电力制氢并注入天然气管网存储的可行性,建立了耦合风力发电、电解水制氢以及天然气管网计算的仿真模型,对管网储氢进行了静态与动态仿真分析。在保证用户节点能量需求的前提下,提出了定压力变流量和变压力定流量的天然气管网输运策略。静态仿真结果表明,两种策略下天然气管网均可实现氢气存储,且各用户节点的天然气消耗量均有降低。由于变压力定流量策略下管网天然气消耗量降低较显著,基于该输运策略提出了储配气站压力动态调整方法;动态仿真结果表明,该动态调整方法在节省管网储配气站天然气输入的同时,基本可以满足用户节点的能量需求。通过分析可知,变压力定流量策略可兼顾用户节点的能量需求和管网天然气耗量降低,缓解“弃风限电”问题,可供类似电厂参考借鉴。
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 farmby 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 networksto evaluate the feasibility of this method.Two strategies, constant-pressure-variable-flow model and variable-pressure-constant-flow model, are proposed to satisfyenergy needs of usernodes.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 thevariable-pressure-constant-flowmodel has advantages on saving natural gas, a strategy for dynamicadjustments on input points of supply is proposed.Results of unsteady simulations show that this strategycan basically fulfill the needs of user nodes.As a result, that gas networks storing hydrogen generated by a wind farm 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.
