Description

Technical Field

[0001] This utility model relates to the field of wind power and buoyancy combined power generation technology, and in particular to a power generation system based on the conversion of offshore wind energy into gas internal energy and buoyancy potential energy. Background Technology

[0002] Wind energy storage technology converts the kinetic energy of wind into other forms of internal energy for storage. As a clean and renewable energy source, wind energy is receiving increasing attention from countries worldwide. Its reserves are enormous; the global wind energy potential is approximately 2.74 × 10^9 MW, of which 2 × 10^7 MW is usable, which is 10 times greater than the total exploitable hydropower potential on Earth. Wind has been utilized by humans for a long time—primarily through windmills for pumping water and grinding grain—but now, the focus is on how to generate electricity from wind power.

[0003] Current wind power generation technology directly drives the generator to rotate through the wind blades. However, wind power generation is unstable, costly, has poor continuous power generation performance, and low stability, resulting in low wind energy utilization. Therefore, it is necessary to combine wind energy with other clean energy sources to improve the stable use of wind power generation. Utility Model Content
