“…The superconducting magnetic energy storage (SMES) system stores electric energy in the magnetic field created by a DC current flowing through a superconducting coil and released when required. The advantages of SMES devices comparing with other energy storage devices include fast response time, high energy storage density, high energy storage efficiency, long life-time, and little environmental pollution [1][2][3][4][5]. A power inductive energy management system has been applied in SMES system widely.…”

In past decades, the technique of superconducting magnetic energy storage (SMES) has received substantial attention both by academia and industry with the great improvement of applicable high temperature superconductors and relevant control technologies. A bridge-type inductive energy management system topology is presented for SMES applications by using a concept of digitalization. The inductive power charging, storing and discharging status are modelled, and then digitalized for the advanced control implementation. As a consequence, an inductive energy control method can be realized by the digitalized models to satisfy relative project requirements by high efficiency and control precession. New principles and methodologies provide the theoretical foundation to achieve digital power inductor energy control and superconducting inductive energy storage device operation.
