3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
microgrid
It is composed of distributed power generation, electricity load, monitoring, protection and automation devices (including energy storage devices if necessary), and is a basic
Small-scale power supply system with internal power balance.
Note. Microgrids are divided into grid-connected microgrids and independent microgrids.
[Source. GB/T 33589-2017, 3.2]
3.2
grid-connectedmicrogrid
It can be connected to the external grid or run independently, and the microgrid is mainly connected to the grid.
[Source. GB/T 33589-2017, 3.3]
3.3
The electrical connection point of the microgrid to the external grid.
