4. DRED
This application meets the requirements of local Australian grid code (AS/NZS 4777.2) which, among specific requirements
for connection, calls for compatibility with Demand Response Enabling Devices (DRED). The DRED is under control of a
local network operator and allows to put the inverter in one of the Demand Response Modes (DRMs) defined by the
standard:
·DRM 0 Operate the disconnection device
·DRM 1 Do not consume power
·DRM 2 Do not consume at more than 50% of rated power
·DRM 3 Do not consume at more than 75% of rated power and source reactive power if capable
·DRM 4 Increase power consumption (subject to constraints from other active DRMs)
·DRM 5 Do not generate power
·DRM 6 Do not generate at more than 50% of rated power
·DRM 7 Do not generate at more than 75% of rated power and sink reactive power if capable.
·DRM 8 Increase power generation (subject to constraints from other active DRMs)
Currently, it is mandatory to respond to DRM0, which allows the network manager to remotely decouple the installation
from the distribution network.
