This paper introduces a novel multiplex voltage source converter topology based on common DC bus. Except from the excellent characters of traditional VSC, the capacity of the system can be expanded. Dual mode control is proposed to stabilize DC bus voltage, when the superconducting inductor current is between the maximum and the minimum allowable value, chopper control mode is adopted; when the current...
In recent years, with the rapid development of renewable energy, power energy storage has become a bottom neck of its development, and superconducting magnetic energy storage (SMES) seems to be a viable solution. A topology based on common DC voltage bus is proposed for high power voltage source converter (VSC)-SMES. The mathematical model of SMES is constructed and the detailed control strategy is...
A prototype, double-DSPs controlled power conditioning system (PCS) for super-conducting magnetic energy storage (SMES), is used for experimental research in dynamic simulation test of power system. The function of SMES is to improve the dynamic performance of a single-machine infinite bus for power system. The experimental results show that the energy transfer of SMES is done almost immediately depending...
