Micro-grid access distribution network operation control specification

1 Scope

This standard specifies the micro-grid access distribution network operation and control should follow the norms and requirements. Including the operation mode and control strategy of microgrid Slightly, tie line exchange power control, and/off-grid conversion control, relay protection and safety automatic device, grid abnormal response, power quality, communication With automation, lightning protection and grounding. This standard applies to access 35kV and below voltage level distribution network microgrid system.

3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Microgrid Composed of distributed generation equipment, electricity load, monitoring/protection and automation devices (including energy storage if necessary) The internal power is basically a small balance of power network. It can be both grid operation with the external power grid, you can also run independently from the network. 3.2 Pointofinterconnection Micro-grid and distribution network electrical connection point. 3.3 Plan off-line intentionaloffgrid Microgrid in accordance with pre-planned by the grid mode switch to off-grid mode. 3.4 Unplanned off-grid unintentionaloffgrid When the microgrid detects a power grid anomaly, the unplanned switch from the grid-connected mode to the off-grid mode. 3.5 Island islanding Part of the power grid that contains the load and power supplies will remain isolated until it detaches from the primary network. Isolated islands can be divided into non-planned islands and meters
