Compressed gas energy storage power station device

Abstract

A compressed gas energy storage power station device comprises an applied energy converting part, a liquid columnar pressure part, a tunnel volume space energy storing and constant pressure graded energy storing part, and an energy releasing and power generating part. Via depth drop height generated from a vertical shaft extending into the ground, liquid materials in the vertical shaft are enabled to generate constant pressure so as to press on tunnel space in the vertical shaft, when energy capable of being converted into compressed gas energy requires to be stored, the applied energy converting part converts the energy into the compressed air energy which is injected into tunnels to be stored, and along with increased accumulation of energy gas storage, the liquid materials in the tunnels are naturally pressed to the ground by the gas. When energy needs to be released, the liquid materials on the ground naturally flow to the tunnels to press the gas to be exhausted to a turbo generator unit to generate power which is supplied to a power grid and a pitch peak. A novel large-power capacity energy storing method is provided besides high-elevation lake energy storage, the problem about large-power capacity storage can be fully solved, and the bottleneck problem that wind power, solar energy, power grid and the like are limited by the pitch peak can be solved.

Description

(1) Technical field [0001] The invention relates to an energy storage power station device for storing compressed gas energy. In particular, it relates to a compressed gas energy storage peak-shaving power station device that uses a liquid columnar natural constant pressure tunnel with a large capacity to store gas energy. (2) Background technology [0002] With the rapid progress of human society and the development of civilization, the demand for electricity in energy sources is increasing throughout the world. And the increasing demand for electricity is also accompanied by an increasing difference in the peak-to-valley amount of electricity consumption. Due to the limited peak-shaving capacity of the existing transmission and power grid, and the number of existing Gaohu energy storage power stations is very small, it can only play a small role in the peak-shaving of the entire power grid. Therefore, it is far from being able to meet all the needs of current and future ...

AI Technical Summary

Problems solved by technology

Reservoir energy storage is mainly used for power generation and is difficult to use for peak regulation, while high lake energy storage has the above-mentioned harsh conditions and many shortcomings and defects.

Therefore, the existing energy storage methods and facilities cannot meet the peak-shaving needs of the existing and future vast power grids, and the resulting waste of resources is very alarming, and therefore seriously hinders and restricts the energy of the new energy road.
