Advanced storage batteries such as lithium ion batteries, sodium sulfur batteries, nickel-metal hydride batteries and the like have higher cost, the high-capacity energy storage technology is not mature, the performance of the product cannot meet the requirement of energy storage at present, and the economical efficiency cannot realize commercial operation.
The electromagnetic energy storage utilizes a superconductor to manufacture a coil to store magnetic field energy, does not need energy form conversion during power transmission, has the advantages of high response speed, high conversion efficiency, large specific capacity/specific power and the like, and can fully meet the requirements of voltage support, power compensation and frequency regulation of a power transmission and distribution network and improve the stability and power transmission capability of a power grid. Compared with other energy storage technologies, superconducting electromagnetic energy storage is still expensive, and besides the cost of the superconductor itself, maintaining the system at a low temperature results in an increase in maintenance frequency and considerable costs. At present, many superconducting electromagnetic energy storage projects are running or in development worldwide. Therefore, how to utilize or store energy efficiently is a worldwide problem.
