In a microgrid, Distributed generations (DGs) are used as an alternate source of electrical power. They can be used as independent source of power in an off-grid mode. DGs can also be used with the power grid to supplement deficit power. DGs are located at the site of power consumption, so the losses in transmission is negligible or almost zero. This results in a significant increase of the microgrid efficiency.

In Islanded microgrid, the microgrid is diconnected from the conventional power grid. The power requirements are met with by using DGs to meet the power demands. It could be possible that only one DG is sufficient to power the microgrid or it may be done using multiple DGs, like multiples solar panels, use of diesel generators, etc.

For the existing microgrids to become a smart electrical network, there is a need of smart electrical energy meter which measures the amount of energy generated at a DG and the energy consumed by the respective load. There is a need to measure and record the deficit power and excess power throughout the day.
