Comparion of Three Types of Fault Current Limiters Used in High Penetration Microgrid

Abstract

In this paper, three different types of economic fault current limiters (FCLs) are suggested to protect a high penetration microgrid. Related theoretical modeling and simulation analysis are carried out, and also the performance comparison of these economic FCLs to deal with short-circuit fault is conducted. At the end, aiming at each type of economic FCL, the relationship between its current-limiting ratio and production cost is determined, and it is helpful for the capacity design and future application of these economic FCLs in the high penetration microgrid.
