Smart Grid Definition

5

"Smart grid" is a concept with many elements where monitoringand control of each element in the chain of generation,transmission, distribution and end-use allow our electricitydelivery and use more cost effective.

Virginia Tech Approach Highlights

31

Detailed customer usage data is stored at customer premises

Customer data privacy is ensured

Customer can pick and choose which appliances to control

Unidirectional communication with existing communicationchannels leads to lower investment and operational cost,reduction in complexity, and therefore lower deployment risk

This approach allows the citizen, the regulator, the electric utilityand the business partner to gain experience with the smart gridand be convinced of its value without a large up front investment
