What role do power electronics play in microgrids?

Power electronics play an important role in microgrids due to the penetration of renewable energy sources. While microgrids have many benefits for power systems, they cause many challenges, especially in protection systems.

What is a microgrid and how does it work?

A microgrid is characterized by the integration of distributed energy resources and controllable loads in a power distribution network. Such integration introduces new, unique challenges to microgrid management that have never been exposed to traditional power systems.

Are microgrids a threat to protection systems?

While microgrids have many benefits for power systems, they cause many challenges, especially in protection systems. This paper presents a comprehensive review of protection systems with the penetration of microgrids in the distribution network.

Can a microgrid protect a power system?

Protection systems need to be reviewed to consider the integration of distributed generation technologies. The presence of a microgrid causes many challenges in the protection of the power system. This study addressed these challenges and their solutions.

Are H-field and E-field energy available in power grids?

However, under the very specific context of power grids, H-field and E-field energy should be more intensively studied on behalf of field applications, as their available amount is significantly higher than the other energy forms, while any systematic review on this part is infrequently reported.

How are power grid infrastructures changing?

Authors to whom correspondence should be addressed. In recent years, power grid infrastructures have been changing from a centralized power generation model to a paradigm where the generation capability is spread over an increasing number of small power stations relying on renewable energy sources.
