6 FAQs about [Concept of load in microgrid]

Why is microgrid important in Smart Grid development?

Microgrid is an important and necessary component of smart grid development. It is a small-scale power system with distributed energy resources. To realize the distributed generation potential, adopting a system where the associated loads and generation are considered as a subsystem or a microgrid is essential.

What is the nature of microgrid?

The nature of microgrid is random and intermittent compared to regular grid. Different microgrid structures with their comparative analyses are illustrated here. Different control schemes, basic control schemes like the centralized, decentralized, and distributed control, and multilevel control schemes like the hierarchal control are discussed.

What are load frequency control methodologies in microgrid?

LFC of microgrid is a promising field and lot of researches are being done in this area which includes various intelligent control methods to application of robust controllers in islanded mode of MG operation. This paper provides a comprehensive review on various load frequency control methodologies in microgrid.

Why is microgrid isolated from main grid?

When microgrid is isolated from main grid because of maintenance or repair works in main grid, it is intentional islanding. Islanding resulting from faults in the utility grid is called unintentional islanding.

How does an AC microgrid work?

Since an AC microgrid is actually a small-scale AC power system, this connection is easier. When the energy generation does not meet the energy demand, the power grid supplies the required energy to the microgrid. If the generation is greater than the demand, the excessive energy in the microgrid is exported to the power grid.

What are microgrid control objectives?

The microgrid control objectives consist of: (a) independent active and reactive power control, (b) correction of voltage sag and system imbalances, and (c) fulfilling the grid's load dynamics requirements. In assuring proper operation, power systems require proper control strategies.
