Superconducting magnetic energy storage (SMES) systems store energy in the magnetic field created by the flow of direct current in a superconducting coil that has been cryogenically cooled to a temperature below its superconducting critical temperature. This use of superconducting coils to store magnetic energy was invented by M. Ferrier in 1970.
The magnetized superconducting coil is the most essential component of the Superconductive Magnetic Energy Storage (SMES) System. Conductors made up of several tiny strands of niobium titanium (NbTi) alloy inserted in a copper substrate are used in winding majority of superconducting coils .
It stores energy in a superconducting coil in the form of a magnetic field generated by a circulating current. The maximum stored energy is determined by two factors. The first is the size and geometry of the coil, which determines the inductance of the coil. Obviously, the larger the coil, the greater the stored energy.
It stores energy in the magnetic field created by the flow of direct current (DC) power in a coil of superconducting material that has been cryogenically cooled. The stored energy can be released back to the network by discharging the coil.
An adaptive power oscillation damping (APOD) technique for a superconducting magnetic energy storage unit to control inter-area oscillations in a power system has been presented in . The APOD technique was based on the approaches of generalized predictive control and model identification.
This use of superconducting coils to store magnetic energy was invented by M. Ferrier in 1970. A typical SMES system includes three parts: superconducting coil, power conditioning system and cryogenically cooled refrigerator.

As a consequence of Faraday''s law of induction, any loop of wire that generates a changing magnetic field in time, also generates an electric field. This process takes energy out of the wire through the electromotive force (EMF). EMF is defined as electromagnetic work done on a unit charge when it has traveled one round of a conductive loop. The energy could now be seen as stored in the electric field. This process uses energy from the wire with power equal to the electr…
