This storage system is known as Superconducting Magnetic Energy Storage (SMES) 2, 3. This rather simple concept was proposed by Ferrier in 1969 4 . The magnetic stored energy ( W mag ) is determined by a coil''s self inductance ( L ) and its current ( I ) or, equivalently, by the magnetic flux density and field integrated over all
One method to mitigate power fluctuations is to use storage batteries [8] and superconducting magnetic energy storage (SMES) [9], [10]. An SMES system consists of superconductor coil, power-conditioning system, cryogenic refrigerator, and cryostat/vacuum vessel to keep the coil in the superconducting state.
The Superconducting Magnetic Energy Storage (SMES) has excellent performance in energy storage capacity, response speed and service time. Although it''s typically unavoidable, SMES systems often have to carry DC transport current while being subjected to the external AC magnetic fields.
Few energy storage systems in the form of compressed air energy storage (CAES) has drawback of site limitation and hence the cost of CAES is same as that of pumped hydro storage. Also, for NaS battery, the lifetime is shorter compared to that of SMES, and hence the annual cost of NaS battery is doubled when compared with SMES

Superconducting magnetic energy storage (SMES) systems use superconducting coils to efficiently store energy in a magnetic field generated by a DC current traveling through the coils. Due to the electrical resistance of a typical cable, heat energy is lost when electric current is transmitted, but this problem does not exist in an
Abstract — The SMES (Superconducting Magnetic Energy Storage) is one of the very few direct electric energy storage systems. Its energy density is limited by mechanical considerations to a rather low value on the order of ten kJ/kg, but its power density can be extremely high. This makes SMES particularly interesting for high-power and short
Nearly 70% of the expected increase in global energy demand is in the markets. Emerging and developing economies, where demand is expected to rise to 3.4% above 2019 levels. A device that can store electrical energy and able to use it later when required is called an "energy storage system".

For short-term energy storage, there is also the possibility to use direct Electrical Energy storages (EES) such as Super Capacitors (SC) [13,14] and Superconducting Magnetic Energy Storage (SMES) [15], which are mainly used as grid stabilisation units.
Due to self-requirement of power for refrigeration and high cost of superconducting wires, SMES systems are currently used just for short duration energy storage [2].

To effectively compete with the other energy storage systems (EES), SMES must be cost-effective (initial costs and lower lifetime costs). Compared to the
Obviously, the energy storage variable is usually positive thanks for it is unable to control the SMES system by itself and does not store any energy, it can be understood that the DC current is usually positive. Thus, the energy storage variable is usually positive for a finite maximum and minimum operating range, namely, expressing

Added to that is the fact that the magnet itself can be cycled potentially an infinite number of times and that it is capable of providing very large
