In 1969, Ferrier originally introduced the superconducting magnetic energy storage (SMES) system as a source of energy to accommodate the diurnal variations of power demands . An SMES system contains three main components: a superconducting coil (SC); a power conditioning system (PCS); and a refrigeration unit (Fig. 9).
It’s found that SMES has been put in use in many fields, such as thermal power generation and power grid. SMES can reduce much waste of power in the energy system. The article analyses superconducting magnetic energy storage technology and gives directions for future study. 1. Introduction
Furthermore, the study in presented an improved block-sparse adaptive Bayesian algorithm for completely controlling proportional-integral (PI) regulators in superconducting magnetic energy storage (SMES) devices. The results indicate that regulated SMES units can increase the power quality of wind farms.
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.
The authors in proposed a superconducting magnetic energy storage system that can minimize both high frequency wind power fluctuation and HVAC cable system's transient overvoltage. A 60 km submarine cable was modelled using ATP-EMTP in order to explore the transient issues caused by cable operation.
Keywords: SMES, storage devices, large-scale superconductivity, magnet. Superconducting magnet with shorted input terminals stores energy in the magnetic flux density (B) created by the flow of persistent direct current: the current remains constant due to the absence of resistance in the superconductor.
