6 FAQs about [Dual protection microgrid 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.

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 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 ].

Does communication failure affect adaptive microgrid protection schemes?

Habib HF, Lashway CR, Mohammed OA (2018) a review of communication failure impacts on adaptive microgrid protection schemes and the use of energy storage as a contingency. IEEE Trans Ind Appl 54 (2):1194–1207 Lai K, Illindala MS, Haj-Ahmed MA (2015) Comprehensive protection strategy for an islanded microgrid using intelligent relays.

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.
