Natural energy storage power generation method and power generation system thereof

Abstract

The invention provides a natural energy storage power generation method and a power generation system thereof. The method comprises the following steps of firstly generating electricity by utilizing natural energy such as wind energy or solar energy, and compressing air, or directly compressing air, and generating electricity for a power grid by utilizing the compressed air as a power source. The air drives an air compressing device by utilizing a comprehensive energy power generation station to generate electricity, thereby producing compressed air through the air compressing device as an energy storage medium, and storing the compressed air in an air storage device, and further using the storage compressed air as the main drive energy or auxiliary drive energy for the other power generation stations, so as to realize the functions of stabilizing and peak compensation.

Description

technical field [0001] The invention relates to an energy storage power generation system, in particular to a natural energy storage power generation method combined with solar energy and wind energy and a power generation system thereof. Background technique [0002] Human beings' exploitation of fossil fuels, such as oil and coal, has an increasing environmental impact, and the supply of such energy sources is limited and depleted. Therefore, the power generation system using wind energy and solar thermal energy has been highly valued worldwide, and has also achieved rapid development in recent years. Common wind turbines that use natural wind to drive blades, and solar energy as a heat source that is converted into mechanical energy to drive generators have all entered the stage of industrial utilization. However, the above-mentioned forms of utilizing wind energy and solar energy have defects such as excessive dependence on natural conditions such as wind power and suns...

Problems solved by technology

[0003] The disclosed technical solutions are insufficient for peak regulation of output electric energy, and the most difficult technical problem at present is that it is impossible to obtain stable electric energy output when using solar energy, wind energy and other unstable natural energy sources to generate electricity, especially in parallel with the public power grid. This defect is more prominent when the network

Although the existing wind power plants can solve this problem, they use expensive frequency matching systems for this purpose, which is a bottleneck for this clean energy not to be fully promoted

[0004] The disclosed technical solutions mentioned above cannot achieve effective production capacity with industrial utilization value. In addition to not being able to fully tap the potential energy of natural energy, the wind power generation device as the main power generation component has not considered the particularity of this type of system. With a special structural design, therefore, the energy that can do work cannot be fully utilized
