Smart Metering

 

The digital grid does not refer to the electrical current. It refers instead to an essentially a self-diagnosing grid infrastructure consisting of intelligent digital sensors.


The architecture also includes real-time decision support for customers and utilities. For example, this often includes smart appliances and thermostats that can automatically throttle energy consumption during peak load periods to avoid the necessity of rolling blackouts, etc. Utilities will generally also move towards demand-response pricing models, so that variable rates apply to energy depending on the overall load on the grid. It is also possible to build better security into such a grid than currently exists. But some want to transmit  pulses of energy -- if we had storage.

 


New Functions:


- Remote meter reading 

- New meters and switches for selective 
  “shutouts” down to within the home or 
  office

- Functions enabled by ubiquitous sensing
- New appliances with power cost functions
- Proactive control by the utility eg It turns 
  up/down the thermostat via “Zigbee”

- Fault detection, repair and recovery.
