6 FAQs about [Grid-connected and off-grid microgrid systems]

Are microgrids a smart power system?

Microgrids and their smart interconnection with utility are the major trends of development in the present power system scenario. Inheriting the capability to operate in grid-connected and islanded mode, the microgrid demands a well-structured protectional strategy as well as a controlled switching between the modes.

What is a microgrid and how does it work?

A microgrid is a group of interconnected loads and distributed energy resources within clearly defined electrical boundaries that acts as a single controllable entity with respect to the grid.2 A microgrid can operate in either grid-connected or in island mode, including entirely of-grid applications. Figure 1 shows one example of a microgrid.

What is a residential microgrid?

One appealing residential microgrid application combines market-available grid-connected rooftop PV systems, electrical vehicle (EV) slow/medium chargers, and home or neighborhood energy storage system (ESS). During the day, the local ESS will be charged by the PV and during the night it will be discharged to the EV.

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.

What is a stand-alone microgrid?

A stand-alone microgrid or isolated microgrid, sometimes called an "island grid", only operates off-the-grid and cannot be connected to a wider electric power system. They are usually designed for geographical islands or for rural electrification.

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.
