6 FAQs about [Microgrid distortion-free current limiting]

Can Superconducting fault current limiter improve power quality in microgrids?

This research paper presents a new approach to address power quality concerns in microgrids (MGs) by employing a superconducting fault current limiter (SFCL) and a fuzzy-based inverter.

How do distributed generators contribute to microgrid fault currents?

In the event of a fault, distributed generators (DGs) contribute differently to microgrid fault currents depending on the DG type, which can be synchronous-based or inverter-interfaced. For inverter-interfaced DGs (IIDGs), an inverter serves as an interface medium between the RESs and micro-grid.

How to limit iidg fault currents?

An alternative and feasible solution to limit the IIDG fault currents is the use of VI-FCLs. Controlling the IIDG as a voltage source behind a virtual impedance during faults protects the inverter switches from overcurrent or thermal damage and ensures the stable and reliable operation of islanded microgrids.

How do droop-based iidgs in Islanded microgrids work?

Does a two-phase and three-phase dip in grid voltage limit inverter current?

The results under two-phase and three-phase dip in the grid voltage shows that the proposed control strategy injects maximum reactive and active power and limits the inverter current by quickly activating the APC control loop during fault-ride-through period.

What are the effects of nonlinear loads on microgrids impedance?

Voltage distortion, a poor power factor (PF), and stress on supply power system equipment are all caused by harmonics in these non-linear loads. Harmonics from no sinusoidal loads has an impact on the electrical microgrids impedance.
