Abstract

The invention provides a hydrogen production method and system by wind power, photoionization / grid connection, and relates to the technical field of wind power hydrogen production. The power supply ofthe hydrogen production device is a main wind power plant wind turbine generator set grid and an energy storage unit, and the energy storage unit is connected with a vertical axis wind turbine generator set of a hydrogen production plant and a photovoltaic battery panel as an auxiliary power generation unit; On the premise of meeting the demand of power grid, hydrogen is produced by utilizing theexcess electric energy of power grid. When the excess electric energy of power grid is too low, the electric energy of energy storage unit is released and supplemented for hydrogen production, so that the input power of a hydrogen production device is smoother and more stable. The hydrogen production device comprises an alkaline electrolytic cell and a solid oxide electrolytic cell. The inventionmainly solves the problem of wide power fluctuation of hydrogen production by wind power existing in the prior art, makes the input power of the hydrogen production device smooth, and improves the efficiency and service life of the hydrogen production device.

Description

technical field [0001] The invention relates to the technical field of new energy power generation and hydrogen production. Background technique [0002] With the continuous prominence of environmental problems, new energy has entered people's field of vision, and wind power technology has continued to develop. Due to the volatility and irregularity of wind power, the generated electric energy does not match the electric energy demanded by the grid, resulting in a lot of "abandoned wind". The "wind abandonment" problem has caused a serious waste of resources, so the search for high-capacity energy storage devices has become a common research topic. Traditional chemical energy storage technologies have disadvantages such as small capacity and short lifespan. As an important technical means of energy storage, hydrogen production from wind power has the advantages of high capacity, easy transportation and no pollution. As a green new energy, hydrogen energy has the character...
