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
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.
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.
The first step is to design a system so that the volume density of stored energy is maximum. A configuration for which the magnetic field inside the system is at all points as close as possible to its maximum value is then required. This value will be determined by the currents circulating in the superconducting materials.
This system is among the most important technology that can store energy through the flowing a current in a superconducting coil without resistive losses. The energy is then stored in act direct current (DC) electricity form which is a source of a DC magnetic field.
A SMES operating as a FACT was the first superconducting application operating in a grid. In the US, the Bonneville Power Authority used a 30 MJ SMES in the 1980s to damp the low-frequency power oscillations. This SMES operated in real grid conditions during about one year, with over 1200 hours of energy transfers.
If the cost of the refrigeration process is eliminated by using a room temperature (or near room temperature) superconductor material, other technical challenges toward SMES must be taken into consideration. A superconducting magnet enable to store a great amount of energy which can be liberated in a short duration.
