Fundamental innovation in high-speed protection and integration mechanism will enable higher efficiency and rigidity to the grid. Many of adverse effects on the grid such as short circuit and protection, electromagnetic transient and voltage stability, power leveling and energy balancing can be mitigated by use of new forms of superconducting technologies. By optimally integrating the superconducting technology that has been predicted to become even cheaper by 2030-50 (NREL long-term target), would diminish these kinds of concerns as compared to existing technologies.
The superconducting Fault Current Limiter (SFCL) is one such technology that drew interest after the discovery of high-temperature superconducting (HTS) materials. Also, due to the recent development of cheaper second-generation high HTS wires, the SFCL has become more viable. Large-capacity SMES also can provide individual or across multiple applications as an integral part of the large scale distributed energy systems. The basic role of energy storage is to draw energy generated at one time and to release it to supply power at a later time.
