英文摘要	The rise of power-to-gas (P2G) technology provides an effective way for the absorption of low-carbon intermittent energy sources such as wind energy and photovoltaics. At the same time, the application and promotion of power-to-gas (P2G) are beneficial to the realization of carbon-neutral goals and realize carbon recycling. This paper analyzes the principle of the power-to-gas process, including the two steps of power-to-hydrogen (P2H) and methanation, and analyzes how to use a power-to-gas facility to increase the grid-connected ratio of new energy power generation and alleviate wind and solar abandonment. This paper proposed a solution to the above problem, and analyzed the effect of power-to-gas on carbon capture, at the same time calculated the number of carbon emissions that can be reduced in the unit of energy produced, and finally, we can conclude that power-to-gas is effective in stabilizing new energy volatility and carbon neutrality and have significant social benefits and economic value. The main component of natural gas is methane, so the methane produced by P2G can be directly injected into the natural gas pipeline. Since the rate of methane production fluctuates frequently. Therefore, it will cause frequent fluctuations of the gas in the pipeline, which may cause the gas pressure, flow, and pipeline pack to exceed the limitation. This paper uses the method of characteristic to solve the differential equation of the pipeline to analyze the dynamic fluctuation process of pressure, flow rate, and pipeline-pack, and finally compared with thermodynamic calculation to verify the correctness of the algorithm. © Published under licence by IOP Publishing Ltd.
