Wind-light-hydrogen-electricity energy conversion demonstration system

Abstract

The invention provides a wind-light-hydrogen-electricity energy conversion demonstration system, including a wind energy generation unit, a solar energy generation unit, an electrolytic hydrogen production unit, a metal hydride hydrogen storage unit, a fuel cell and a load. After the wind energy and solar power generation units generate power, through the electrolytic hydrogen production unit, the power is converted into hydrogen energy, the metal hydride hydrogen storage unit stores hydrogen, and according to the need, the fuel cell hydrogen is supplied with hydrogen to carry out power generation and also can serve as a storage unit, so that long-term lossless storage and long-distance transport of hydrogen energy is achieved. The system directly and vividly shows the conversion among wind energy, solar energy, hydrogen energy and electric energy, and realizes the interconnection and energy storage of renewable clean energy through energy conversion. The demonstrate system can be used for teaching demonstration and student experiments, which is of great significance to improve classroom fun and students' enthusiasm and improve students' awareness of renewable energy efficient use, conversion, energy storage and energy saving.

Description

technical field [0001] The invention relates to an energy conversion demonstration system for wind energy, solar energy, hydrogen energy and other renewable energy sources. Background technique [0002] With the depletion of fossil energy and the intensification of environmental pollution, the development of renewable energy and energy-saving and emission-reduction technologies is the main measure taken by countries around the world. The development and utilization of renewable energy resources and the increase of the proportion of renewable energy in the energy structure are also important. An important strategy for my country's energy development. [0003] Judging from the current resource status and technological development level of renewable energy, besides water energy, the fastest-growing renewable energy is mainly wind energy, solar energy and biomass energy. my country has made remarkable achievements in the construction of wind power and solar energy, but there are...

AI Technical Summary

Problems solved by technology

my country has made remarkable achievements in the construction of wind power and solar energy, but there are still certain problems. Wind power and photovoltaic power generation have problems of instability and discontinuity. The grid connection will have a certain impact on the grid, so there are certain restrictions on the amount of grid connection.

[0004] Taking wind power as an example, my country's wind power generation is mainly concentrated and large-scale developed in the Northeast, Northwest, and North China regions. As the main power supply, thermal power generation is difficult to adjust and operate on a large scale to reduce power generation. When the power load is low and the wind power generation capacity When it is larger, there will be a problem of abandoning wind, resulting in a lot of energy waste
