Superconducting magnetic energy storage system using superconducting coils to store energy in the form of electromagnetic energy, Superconducting magnetic energy storage not only can reactive power compensation but also can active thought the power of mediation. It can achieve the power of the four-quadrant operation. This article outlines the advantages of the superconducting energy storage technology and development status, superconducting energy storage and how various components used. Finally describes how the four-quadrant active and power exchange. I think 21st century technology superconducting will develop far-reaching impact semiconductors as the 20th century semiconductors. So it has a great significance.

In this article, a comprehensive model for power quality assessment of a standalone wind-diesel-superconducting magnetic energy storage system is developed using firing angle control scheme of superconducting magnetic energy storage unit. A four-quadrant operation of superconducting magnetic energy storage unit is proposed where firing angle of superconducting magnetic energy storage converter is controlled depending upon active and reactive power demand of wind-diesel system, under various disturbances. Superconducting magnetic energy storage is designed as a controllable current source capable of reducing both frequency and voltage deviations simultaneously. For continuous control of superconducting magnetic energy storage unit, a regulating variable is formulated which forces the superconducting magnetic energy storage current to return to its nominal value after handling a disturbance in order to handle a new disturbance. Frequency of the system is estimated using the concept of centre of inertia. System performance is assessed for disturbances of higher magnitudes. Complete modelling is carried out in MATLAB/Simulink environment, and simulation results demonstrate that the scheme gives expected results under load disturbance and wind perturbations.
