Structure of typical microgrid energy management system. A microgrid has two operation modes, namely on-grid and off-grid operation. When a microgrid is detected to be islanding, or it needs to operate independently according to prevailing situation, it should rapidly disconnect from the public grid to switch into the off-grid operation mode.
A microgrid is a single controllable unit composed of distributed generation, energy storage, and load from an aspect of a system.
