@Dave, thank you for sharing your thoughts about smart electrical panels and ethernet communication over power lines.

Update: ITU approves new worldwide smart grid standards http://bit.ly/vdyELy

Smart Grids, Smart cities, Smart homes, where does it start?
“In today’s scenario any decrease of power to a residence/business does nothing to allow for the various appliances to “tone down” their operation in order to prevent total shut down and possible loss of A/C, food, emergency medical equipment, etc.
This is a greater issue than plain smart grid technology and tougher to address”

Based on the quoted statement the following is submitted. I believe that with the use of smart electrical panels that receives communications from end devices (medical equipment, HVAC, Refrigeration…) through Ethernet over power and the use of device ID’s much like a MAC address or an ESN. The smart panel would communicate back to the grid how much power would be required thus only allowing for a “Brown out” scenario to reduce power consumption and result in a power savings to the customer and the grid.

@Frank, thank you for sharing your thoughtful observations and perspective about potential enhancements to existing energy management solutions.

That seems like a very useful benefit — enabling the consumer to assign a priority (or weighting factor) to home appliances and other devices. I’m sure the variety of potential household scenarios would require a flexible and yet simple method of configuration. The user interface for accessing the in-home controller would be important.

A case in point: I’m a “tech-savvy” person, and yet I have to refer to the printed manual any time I want to make changes to the programs for the irrigation sprinkler system at our home.

David,
I have been involved in smart grid technology for a while using a device that is mounted at the residence/business. It effectively removes the current meter and replaces same with an intelligent device that can communicate information back over the grid to various new and existing OS’ at the utility.
There is, however, another requirement which I have not seen addressed but will require the cooperation of the appliance manufacturer.
In today’s scenario any decrease of power to a residence/business does nothing to allow for trhe various appliances to “tone down” their operation in order to prevent total shut down and possible loss of A/C, food, emergency medical equipment, etc.
This is a greater issue than plain smart grid technology and tougher to address.
Sincere regards,
Frank Rice
