Australia introduces a unique appliance interface for delivering demand response. And it is known as the Demand Response Enabling Device (DRED).
DRED allows a regulating authority and provides instructions most often a power supply company, to limit the power amount that an air conditioner can consume. In contrast to its normal full load power consumption. The primary goal is to reduce total power consumption to the minimum in the supply network during crucial peak load times. It sends a ripple down to the power supply, generating a response in return.
A Demand Enabled Response (DRED) air conditioner allows your electricity provider to control the system at various pre-program levels, to manage your demand on the power grid during peak periods.
Most of the Daikin models are capable of using this option, requiring an additional adaptor accessory. Requires additional purchase and installation.
DRED offers the capacity to demand three different degrees of air conditioner response: DRM1, DRM2, and DRM3.
DRM1, which stands for “compressor off,” is the bare minimum requirement to meet the Australian standard.
The DRM2 cannot exceed 50% of the total kW capacity.
The DRM3 cannot reach 75% of the total kW capacity.
AUSTRALIAN STANDARDS The AS/NZS 4755 set of standards gives comprehensive information on the various Demand Response Enabling Device (DRED) Modes for various equipment. AS/NZS 4755.3, in particular, addresses Energy Storage Systems, whereas DR AS/NZS4755.6 addresses Demand Response Enabling Devices.
Eventually, the majority of manufacturers such as Daikin, Fujitsu, or Samsung can incorporate this feature into their new products.
