Abstract

The invention discloses a power generation system based on the coupling of renewable energy hydrogen production and biomass gasification and a working method. The power generation system comprises a renewable energy power generation device, a power distribution device, a water electrolysis hydrogen production device, a hydrogen storage tank, an oxygen storage tank, a biomass gasification device, ahydrogen and gas mixing device and a gas-fired boiler power generation device. The renewable energy power generation device, the power distribution device and the water electrolysis hydrogen production device are connected in sequence. The water electrolysis hydrogen production device is connected with the hydrogen storage tank and the oxygen storage tank. The oxygen storage tank is connected with the biomass gasification device. The hydrogen storage tank and the biomass gasification device are both connected with the hydrogen and gas mixing device. The hydrogen and gas mixing device is connected with the gas-fired boiler power generation device. The power distribution device and the gas-fired boiler power generation device are connected with a power grid. Through water electrolysis hydrogen production by means of electricity abandoning, large-scale storage and consumption of renewable energy sources can be achieved, the water electrolysis hydrogen production cost is reduced, generated hydrogen and biomass gasified fuel gas are mixed for power generation, and the biomass power generation industry layout is accelerated.

Description

technical field [0001] The invention relates to a power generation system, in particular to a power generation system coupled with renewable energy hydrogen production and biomass gasification. Background technique [0002] Since the industrial revolution in the 18th century, traditional fossil energy (coal, oil, natural gas) has been the most important primary energy in human development. However, with the massive exploitation and use of traditional fossil energy, energy depletion, climate change and ecological Environmental problems are becoming increasingly prominent. Therefore, vigorously developing and utilizing renewable energy has become the consensus of the world. However, due to the inhomogeneity and intermittency of water energy, wind energy, and solar energy, the grid-connected transmission of renewable energy power will have an impact on the grid, causing fluctuations and insecurity in the grid, and a large amount of renewable energy power cannot be connected to...
