Smart Meters and HAN there Is different driving forces and should revolve related, but on distinct paths, attempts to artificially combine, them will negatively impact the development of both, the best place for interaction between HAN and Smart Meters would be within the framework of Utilities.
The area HAN and its derivatives will cause the relationship between consumers and utilities to enter into a new level.
Making Smart Meters provide and manage this area - HAN - is difficult from the standpoint of operational and technical.
The changes to the specifications of components and manufacturing techniques Smart Meters will be implemented to enable them to have reliability and longevity the closest possible of the old Meters.
Take these same specifications for the area of HAN is expensive and unnecessarily, because they have different functions and will be installed in an environment far less aggressive than the Smart Meters.
Smart Meters will have at least the following functions:
- Different fields of Tariff, including a field for Demand Response;
- Relay-cutting and automatic restart;
- AMR and DSM;
- Measurement of energy, in KWh;
- Measurement of maximum demand in KW;
- Clock.
Then place it in the same bag will be a great stupidity.
The Utilities have to manage the consumption and demand of their customers, so that each consumer can keep his lifestyle and his own load profile, should never treat their customers globally. On receiving information of consumption and demand for Smart Meters, the Utilities will handle this information and inform the "Control HAN" to make the decisions that this pre-established.
Consumers may together with the Utilities to determine and limit your daily intake of energy, and that application should be turned off if the pre-established limit is exceeded.
These same applications will receive information on prices and Tariffs should be skilful to be connected whenever the price of Tariffs it is more favorable, according to this whenever the desire and need of the consumer.
The consumer may change at any time what kind of application can be managed automatically by the utilities in your home, without warning the Utilities.
For all this, the "Control HAN" should be within the consumer's home, and an easily accessible place and never near a Smart Meter within a box measuring.
The means of communication used between Utilities and Consumers is still undefined, and should have a large number of possibilities.
But the technology of communication between the components of the Han area, the better and cheaper is the Power Line Communication (especially one that is used "cross zero" sine wave - X10). These components can be easily purchased at a store or via the Internet.
Today, any consumer of average intelligence and skill simple, if you have prior knowledge of price Tariffs can schedule a scenario HAN inside your house.
Mainly in the U.S. where the power distribution system is the "Split Phase", which is quite favorable for this technology.
I see no difficulty or complication to the interaction between Smart Meters and HAN, provided it is maintained and understood their fundamental differences.
