The virtual synchronous generator (VSG) technology equips power inverters with virtual inertia and damping to access generation and storage more friendly. However, the VSG's weak performance to withstand fault current inrush and fulfill low-voltage ride-through (LVRT) operation should be carefully addressed. This paper presents an innovative method to coordinate adaptive virtual resistance controller (AVRC) and flux-coupling-type fault current limiter (FC-FCL). First, the theoretical modeling and transient characteristics of the VSG are illustrated. Then, the implementation of the coordin...

The traditional approach to reduce fault current over-duty is to upgrade protection systems or splitting busses in the substations. This upgradation in the substation may put extra financial burden on the grid operators. It also requires extended outages of the substations, which would reduce the reliability of the power system. To solve this problem a saturated amorphous alloy core-based fault current limiter (SAACFCL) can be applied. In this paper, parameters for the SAACFCL have been designed using a tuning process and characterized using advanced electromagnetic and electrical modelling. A...

Abstract This paper proposes the use of a novel saturated amorphous alloy core-based fault current limiter (SAACFCL) to improve the LVRT capability of doubly-fed induction generator (DFIG) based wind energy systems, especially during voltage sag events. Compared to the traditional cores which are widely used in fault current limiter (FCL), amorphous alloy core possesses a very narrow B-H loop which indicates that the SAACFCL requires a smaller dc excitation current, and it will incur low core losses. Under normal conditions, this developed SAACFCL accomplishes low impedance and has a negligib...
