A voltage source converter model for exchanging active and reactive power with a distribution network

In this paper, some of the operational and design characteristics of a distributed superconducting magnetic energy storage (D-SMES) device are presented. The main parts that a D-SMES consists of, the various configurations and operational techniques are discussed. The advantages and disadvantages of superconducting energy storage compared with other solutions are provided. The problems that a D-SMES can deal with are listed and discussed, but in the present work we will focus only on the ability of a D-SMES to alleviate voltage fluctuations and sags (dips) and support a sensitive load during power system outages or interruptions. To demonstrate this ability of a D-SMES device, simulations were performed using the ElectroMagnetic Transients for DC (EMTDC) simulation package. The simulation results are provided and discussed.
