Power grid power generation, hydrogen production and power storage coupling system driven by photovoltaic energy

Abstract

The invention discloses a power grid power generation, hydrogen production and power storage coupling system driven by photovoltaic energy, and belongs to a photovoltaic power generation and hydrogen production system. Solar energy collected by the photovoltaic panel is converted into electric energy, the electric energy converted by the inverter system can be connected into a power grid to be supplied to the power grid, water is electrolyzed to prepare hydrogen or be stored in a storage battery, and then the purpose of comprehensively and efficiently utilizing photovoltaic energy is achieved. The system can efficiently utilize photovoltaic energy in the daytime to supply power to the power grid, prepare hydrogen and store electricity for the storage battery, so that the household electricity consumption is reduced, and carbon emission is reduced.

Description

technical field [0001] The invention belongs to a photovoltaic power generation hydrogen production system, in particular to a grid power generation, hydrogen production and electricity storage coupling system driven by photovoltaic energy. Background technique [0002] Using photovoltaic power generation during sunny hours during the day is a convenient and cheap way to obtain electric energy. It can make full use of the roof area of ​​a home building for photovoltaic power generation. The converted electric energy can be used to drive household appliances or feed back to the grid. [0003] The above-mentioned typical photovoltaic power generation system does not have a self-configured energy storage system. When the photovoltaic power generation is sufficient during the day and the household power load is low, the excess power generated by the photovoltaic power generation can only be sold to the grid company at a lower price; and at night, The household electricity load i...

Problems solved by technology

[0003] The above-mentioned typical photovoltaic power generation system does not have a self-configured energy storage system. When the photovoltaic power generation is sufficient during the day and the household power load is low, the excess power generated by the photovoltaic power generation can only be sold to the grid company at a lower price; and at night, Household electricity load increases, and the power grid in turn directly supplies power to households at a higher price, resulting in economic losses

In addition, a large number of such uncertain and small-scale decentralized household photovoltaic systems connected to the power grid will have an impact on the power grid, and there are certain hidden dangers in the security of the power grid.
