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

Overview (cont)

Jeju Island Population

0.5 million(Korea 60 Million)

Most beautiful Province in Korea

Jeju Island

Jeju Island

2009 = Jeju island demo 2013 = smart city deployment 2020 = Metropolitan Area

Deployment 2030 = Nationwide Deployment

Malta

Consisting of 2 islandssituated in the centre ofMediterranean

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
