FAQS about Grid-connected and off-grid microgrids

What is the difference between a grid-connected system and a microgrid?

The difference between a grid-connected system and a microgrid lies in how it operates, and particularly its level of independence from the main electrical grid. The primary distinctions: 1. Dependence on the main grid: Grid-connected systems still rely on the main grid as their primary source of power.

What if microgrids are not able to connect to the utility grid?

Interconnection is of paramount importance: if microgrids are not able to connect to the utility grid, they must operate permanently in an islanded mode, forfeiting the opportunity to derive revenue from grid services they could otherwise provide and crippling their business case. 5.3.
