Compressed air energy storage (CAES) is an effective solution for balancing this mismatch and therefore is suitable for use in future electrical systems to achieve a high penetration of renewable energy generation.
In the transition to using compressed air as the main energy system, the first sets of commercial-scale compressed-air energy storage systems are the 270 MW Huntorf system in Germany , and Macintosh’s 110 MW CAES plant in Alabama, United States .
Types of compressed-air energy storage (CAES) technologies with variants. As carbonized CAES, supplementary fuel CAES systems are normally fossil-fuel-powered plants or normal compressed-air power systems that use compressed air to enhance power performance or reduce emission footprints.
The compressed air storages built above the ground are designed from steel. These types of storage systems can be installed everywhere, and they also tend to produce a higher energy density. The initial capital cost for above- the-ground storage systems are very high.
The classification also indicates efforts to improve the energy density and RTE of storage units and improve the suitability of CAES for different domains of application. Without regard to scale, classification is based on pressure variation and how it is controlled while focusing on the state of the stored compressed air.
The largest component in such systems is the storage medium for the compressed air. This means that higher pressure storage enables reduced volume and higher energy density.

By studying the influence of air gap on energy storage location, the energy in the process of power conversion can be reasonably stored in the air gap to reduce the loss and increase the efficiency of magnetic device conversion, in addition, by reasonably distributing the size of air gap, improve the magnetic conductivity after adding air gap, adjust the linearity of inductance, and more reasonable magnetic devices are designed to increase the stability of products.

Compare the magnetic core energy storage expression (9) with the total energy storage expression (14), it can be seen that the total energy increases by z-multiple after the addition of air gap, from Eqs. (16), (17) indicate almost all the energy is stored in the air gap, and the energy of magnetic devices expands and increases.
The innovation point of this paper is to analyze storage energy distribution ratio on the core and gap of magnetic devices from the perspective of energy that the storage energy distribution ratio of magnetic devices is changed after the addition of air gap.
By analyzing the effects of air gap length and position on magnetic device parameters, saturation characteristics and linear stability of magnetic devices can be improved without changing the maximum magnetic field strength and coercivity of magnetic devices.
Magnetic core and air gap energy storage On the basis of reasonable energy storage, it is necessary to open an air gap on the magnetic core material to avoid inductance saturation, especially to avoid deep saturation. As shown in Fig. 1, an air gap Lg is opened on the magnetic core material.
However, the larger the air gap is, the effective permeability of the magnetic core will decrease, and the magnetic flux density will decrease under the same current. Therefore, increasing air gap to expand energy storage is limited, Next, control variable method is used to analysis. 4.
It is important to analyze the inner and outer air gap magnetic field between the planets and the two stators, because the results of the air gap magnetic field analysis not only affect the calculation of the torque, noise, and other characteristics, but also directly influence the control performance of the toroidal drive. 11, 12

In response to demand, the stored energy can be discharged by expanding the stored air with a turboexpander generator. [pdf]
