Abstract

The invention provides a wind power, photoionization / grid-connected hydrogen production method and system, and relates to the technical field of wind power hydrogen production. The power source of the hydrogen production device is the power grid of the wind power generator set of the main wind farm and the energy storage unit, and the energy storage unit is connected with the vertical axis wind turbine generator set of the hydrogen production plant and the photovoltaic panel as an auxiliary power generation unit; under the premise of meeting the needs of the power grid , making use of excess electric energy in the power grid to produce hydrogen. When the excess electric energy in the power grid is too low, the electric energy of the energy storage unit is released and supplemented for hydrogen production, so that the input power of the hydrogen production device is relatively smooth and stable; the hydrogen production device includes Alkaline electrolytic cells and solid oxide electrolytic cells. The invention mainly solves the wide power fluctuation problem of wind power hydrogen production in the prior art, smooths the input power of the hydrogen production device, 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 hydrogen production. Background technique [0002] As environmental problems become increasingly prominent, new energy sources come into people's field of vision, and wind power technology continues 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 many "abandoned wind". The problem of "abandoned wind" has caused a serious waste of resources, so seeking 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 by wind power has the advantages of high capacity, easy transportation and no pollution. As a green new energy, hydrogen energy has the characteristics of envir...
