6 FAQs about [Microgrid dual protection access]

How is a microgrid protected by a differential protection scheme?

An adaptive wide-area network technique is used in the current differential protection scheme [ 25 ]. A microgrid with a loop distribution system is protected by a differential protection scheme [ 26 ]. A novel protection scheme uses the THD of the inverter output voltage for fault detection.

Are microgrid protection schemes effective?

In both modes of microgrid operation, the simulation data show that the proposed protection schemes are effective, well-coordinated, and discriminative in fault detection and tripping of the faulty section. It is also worth mentioning that the proposed protection schemes do not need any communication hardware or any switching mode status.

What are the challenges for Microgrid protection in grid-connected mode?

Major challenges for microgrid protection in grid-connected mode include enhancement of fault current magnitude, blinding of protection, sympathetic or false tripping, overreach and under-reach problems of distance relays, relay interoperability, and compliance with grid codes [ 10 ].

Why is a distance protection scheme used for Microgrid protection?

A distance protection scheme is used for microgrid protection to make the protection scheme independent of the current magnitude [ 20, 21 ]. Voltage and current data are generally utilized to calculate the fault path resistance iteratively based on phase coordinates. This technique fails in the case of multi-in feed transmission lines.

What is microgrid-based power system protection?

Microgrid-based power system protection has growing concern for relay tripping time and optimal overcurrent coordination. To limit the fault current, fault current limiters (FCLs) are used during the fault in the transmission system without isolating the grid component.

Is there a superlative protection scheme for microgrids?

The lack of comprehensive protection schemes, which must be attuned with islanded and grid-connected modes of microgrid operation, is a challenging task to be implemented. To grasp the superlative protection scheme for MGs, the combined action of different protection strategies is required.
