6 FAQs about [Grid-connected microgrid application]

What happens if a microgrid is grid-connected?

If the microgrid is grid-connected (i.e., connected to the main electric grid), then the community can draw power from the main electric grid to supplement its own generation as needed or sell power back to the main electric grid when it is generating excess power.

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.

Can a microgrid run autonomously?

A microgrid can run in two modes of operation, in tandem with the grid (grid connected) or autonomously from the grid (islanded mode), and it can be AC MG, DC MG, or hybrid combination (both AC and DC) 3, 4, 5.

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.

How a microgrid is controlled?

In the modern microgrids, the DERs, the ESSs, and the loads are mostly interconnected through power electronics interfaces. The above discussed controls are mostly realized by manipulating the power converters, which is considered as the underlying control.

What is a grid-tied DC-based microgrid?

Lastly, a grid-tied DC-based, non-synchronous architecture simplifies interconnection with the AC grid and permits straightforward plug-and-play capabilities in the microgrid, allowing addition of components without substantial re-engineering .
