A new bridge-type chopper topology using MOSFETs is proposed and studied for superconducting magnetic energy storage (SMES) applications for use in low-voltage end-user sides. Both the bridge-type and conventional choppers are theoretically analyzed and experimentally compared. The dynamic energy exchange characteristics of SMES for solving the voltage swell and voltage sag problems are presented...
A simplified DC superconducting magnetic energy storage (SMES) model is presented in this paper. The theoretical modeling and application topology are introduced with a new digital time-delay control method proposed to achieve required energy exchange. The theoretical analysis and simulation results of the steady and dynamic power and exchange processes verify its feasibility for the design, optimization...
The superconducting magnetic energy system (SMES) is introduced to form new hybrid energy storage systems (ESSs). The results obtained verify that the SMES-based hybrid ESSs suit to achieve ms-level fast power compensation and MW-level large power compensation in power system. The SMES-based hybrid ESSs can also reduce the total capital cost and improve the operation efficiency, which make the large-scale...
