Overview
Overview

is an intelligent integrated
electricity network which is based
on digital technology. The Smart
Grid supplies electricity from
service providers to users by using
two-way communication system in
order to control appliances at users’
houses. This helps ensure efficient
electricity power management

Metropolitan Area Deployment
Nationwide Deployment
Malta

Consisting of 2 islands
situated in the centre of
Mediterranean
Malta



Analogue meters were replaced by
Smart meters
Internet connection tools were installed
to monitor real-time power
This project is expected to complete in
2010
Chicago
Chicago


Chicago has been improving its current
buildings by adding power generation
facilities, and regularly adopting new energy
saving innovations
the Smart Grid infrastructure is now being
developed for volunteer buildings. This
project ranges from power manufacturing at
the beginning of the process, connection
between service provider and users, through
to power supply which can be monitored by
users
Cloud Computing

is a technology that uses the internet and
central remote servers to maintain data and
applications. Cloud computing allows
consumers and businesses to use applications
without installation and access their personal
files at any computer with internet access.
This technology allows for much more
inefficient computing by centralizing storage,
memory, processing and bandwidth
Cloud Computing
Smart Grid Data Cloud



A model for smart gird data management
based on specific characteristic of cloud
computing
The applications of the cloud computing
model meets the requirements of data and
computing intensive smart grid applications
These requirements by analyzing the set of
well-known smart grid use case
Smart Grid Data Cloud




Market liberalization and network
operator regulation
Smart Generation and Wholesale
Markets
Smart Transmission and Distribution
Smart Retail and Consumption
Smart Grid Data Cloud
THE DATA CLOUD MODEL FOR THE SMART GRID
A major challenge is that ICT and data
management costs prevent initiatives
from becoming widely adopted after
pilot project
Sensors and actuators make devices
along transmission and distribution
communicative and controllable
Smart Grid Data Cloud
THE DATA CLOUD MODEL FOR THE SMART GRID
Capital and operational costs of data
management for energy market actors
to make informed decisions about how
to control these resources reach
prohibitive levels if each actor must
replicate infrastructures for managing
data from the same sources
Smart Grid Data Cloud
Smart Grid Data Cloud

Shows data and information flow separated
from the control flow. The rationale behind
this separation is that actuators will be
triggered by the legitimate parties on events.
Whilst sensors and other data sources
external to the power system, such as
weather sensors and electronic markets, will
generate a continuous flow of data which is
subject to the on demand information
retrieval needs of each party
Conclusion

The scope is to demonstrate a platform
for collaboration and information
exchange between end users, retailers,
virtual power plant operators of highly
distributed generation as well as the
network operators
