3 Terms and Definitions

The following terms and definitions apply to this document.

3.3 The electrical connection point of the microgrid to the external grid

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]
