Smart Appliances according to AHAM (USA) and CECED (Europe)

According to AHAM, a smart appliance is defined as: “appliances which monitor, control

and protect their electrical energy usage in response to customer needs”


According to CECED, a smart appliance is defined as: “a household appliance that makes

use of an intelligent power management strategy to optimize the load on the power

distribution grid: it lowers energy cost (for consumer and utilities) and increases the overall

efficiency of the system”.

•AHAM Smart Grid White Paper (http://www.aham.org/ht/a/GetDocumentAction/i/44191)

•http://www.ceced.eu/IFEDE//easnet.dll/GetDoc?APPL=1&DAT_IM=2112CC&DWNLD=Energy%20Management%20with%20

smart%20appliances_rev1.pptx

Both agree that:

1. Pricing must provide incentives to manage energy use efficiently and enable

consumers to save money.

2. Communication Standards must be open, flexible, secure, and limited in number.

3. Consumer Choice & Privacy must be respected: the consumer is the decision maker!

References:

But, the present uncertainty about standards is

slowing down the development of smart

appliances …

Smart Appliances & current Smart Plugs vs Smart Grid’s needs

benefits problems to solve

• Smart appliances contribute to

optimize the load on the power

distribution grid …

1. through a direct dialog with utilities

(Demand Side Management)

2. by reacting to grid frequency

variations (Dynamic Demand

Control)

• Smart appliances allow new

services (remote maintenance,

telecare, other web based services)

• lack of consolidated standards

• cost of connectivity

• products not yet available on the market

(uncertainty about standards and costs to

add )

• too much time (without incentives…) is

required for replacing the household

appliances present on the field

• necessity to find a way for promoting a

rapid spread of smart appliances

• Smart plugs allow energy companies to

control the power supply of household

appliances to avoid power consumption

peaks.

• Smart plugs allow consumers to

become aware of their energy use and

costs.

• Consumers and appliance manufacturers

do not like forced power interruptions for

their products.

• Most of the commercial smart plugs are

not controllable through a local network

Indesit approach to speed up the diffusion of smart appliances


The Indesit approach is based on the following assumptions:

1. The concept of “smart appliance” must impact on the mass production

(avoid niche solutions)

2. The cost of connectivity must have a very low impact on the industrial

cost of the appliance

3. The appliance must be free from protocol constraints

According to these assumptions, Indesit has developed a

communication technology that:

1. can be used by any household appliance equipped with a digital control

system;

2. is based on the electronic resources already present in the appliance

(no cost added);

3. allows to move the “communication node” from the appliance to an

external adaptor (smart plug)

Power Modulation: a point-to-point bidirectional communication

PM = Power Modulation

Smart Plug

Smart Appliance

Wall Socket

The appliance transmits (to the

Smart Plug) 1 bit during each

mains cycle (50/60 bit/s) by

modulating the power absorbed

by one of its electric loads (lamp,

fan, motor, valve, defrosting

heaters ...).

The Smart Plug transmits (to the Appliance) 4 bits during

each mains cycle (200/240 bit/s) through small variations

(12 V pulses) of the mains voltage: the temporal distance

between such pulses and the zero-crossing point of

mains voltage contains the transmitted data.

HAN Home Local

Network

The “communication

node” is moved from the

Appliance to the Smart

Plug, which works as a

network interface.


The Appliance

communicates by

using its control

system: no cost

s added!

Smart Appliances & DDC : PNNL approach

“The GFAC chip can temporarily shift

how smart appliances use power to

soften the blow for utilities during times

of peak demand on the grid.”

Pacific Northwest National Lab (PNNL) has

developed the GFA controller, a simple computer chip

that can be installed in various consumer (household)

appliances.

The GFA controller senses the grid condition by

monitoring the frequency of the system and provides

automatic response in the time of disruption.

Therefore, the GFA controller can provide demand

response capability to household appliances like

refrigerators, air conditioners, water heaters, etc.

Smart Appliances & DDC : Indesit approach (DDC Trial in UK)

SMART FRIDGES TO SAVE THE PLANET – DDC Technology

Indesit Company, RLtec and NPower roll out Europe’s biggest trial of smart fridges

The dynamic demand technology developed by RLtec (now Open Energi) and Indesit research

teams helps to maintain the balance between supply and demand across the national electricity grid.

From 2010 and through 2011, up to 1,200 UK NPower customers was supplied with Indesit Company

dynamic demand fridges and fridge freezers, free of charge, in what will be world’s first residential test

of the technology.

Please watch: http://www.youtube.com/watch?v=LZBAi5id5h0


Indesit does not use an

external device like the GFA

controller, but implements

the DDC function directly

inside the control system of

the fridge (no added cost!)
