what are the information do you think that can be exchanged between smart meter and appliances in a home area network? Generally its a communication that ensures which are the appliances that are working and what is its power consumption.
Other than power consumption and average power consumption per time(to generate consumption graph across the day), it would be interesting, on some areas, to use phasorial variation to determine quality of energy.
Do you me the data that is currently available form a smart meter or the data that would be of interest to an appliance from the smart meter?
Since the smart meter is the first point of contact with the network it might be interesting to have real-time information such as power factor, voltage levels, harmonics present on the network removing the need to include this type of measurement in the appliances but still provide inputs to power optimisation algorithms running on the appliance.
Peak load demand, could be diverted to off peak demand based on load priority, and distribution factor could be improved, with reducing the life consuming cost of machines/eeqipt. of system..Refer my papers.
You don't need a smart meter to achieve that. Just access to market pricing data...
@Jean: I am working on my current research on Smart meter needs for futuristic energy grid. I appreciate your suggestions. But can you please be more specific on the alternative of smart meter in scheiving this. Because my main motto behind measuing power quality is to maintain a helthy grid by receiving real time info from consumer end.
@Bhupenda: I thank you for your suggestion on distribution factor. I will include this on my list.
@sandeep. The alternative of the smart meter measuring various line quality parameters is that every appliance does it on its own and uses that information for its internal controls.
For demand side grid management a smart meter is an obvious choice for aggregating the information before forwarding it to the grid and/or to the appliances. The alternative is that each appliance, light fixture etc. has a connection to the grid's data feed and supplies information to the grid and takes commands from the grid to shed load or increase load to stabilise the grid.
Personally the meter acting as a bridge makes more sense as it reduces costs on the appliances.
