Architecture for Smart Grid based Consumer End Solution

  1. 1. Transmission and Distribution Generation Consumers
  2. 2. Problem Definition - To design low profile, versatile nodes capable of communication between the system designer and the appliances. - To design a generic entity to play administrator over a group of control nodes. - To make available the desired data at the administrator node, and to maintain a database for the specified duration. - We call the control nodes as “SLAVES”, and the administrator nodes as “POWER HUB”. - The POWER HUB listens to the system designer, and implements the required control over the network through SLAVES.
