SmartGrid Definition

The SmartGrid is a new concept of electrical network, which can

intelligently integrate the actions of all users connected to it (generators,

consumers, etc.) in order to efficiently deliver sustainable, economic and

secure electricity supplies.

A SmartGrid employs innovative products and services together with

intelligent monitoring, control, communication and self-healing technologies.

The Kythnos Island Microgrid project provides a demonstration site where photovoltaic panels

with diesel genset for back-up and battery banks as storage device serve twelve houses in a small

microgrid structure, with the main goals of adaptation and installation of the agent-based software

for centralized and de-centralized control.

SmartGrid Project for a Mediterranean Island

The SmartGrid project regards the evolution of the electrical distribution and

generation system of a broad island having a central position in the Mediterranean sea:

it is a feasibility study of the evolution towards the SmartGrid concept of the existing

electrical system.

SmartGrid Project for a Mediterranean Island

The aim is to provide important changes in order to join new and alternative energy

sources, reducing the traditional diesel generation, improve the island sustainability

with waste treatment plant and electrical vehicles, increase intelligence and

automation level, making the electrical system capable of dialogue and interaction

with the needs of the various agents integrated within it.

Energy System

Actually, the island is totally dependent on the mainland. Diesel, petrol and

liquefied petroleum gas (LPG) are imported regularly on the island.

The project aims to reduce substantially this dependency.

Control System

The originally centralized control of electrical system migrates towards a distributed

intelligence, including a hierachical organization of different agents, featuring

bidirectional controls and data flows, eventually allowing users to bargain in a

deregulated energy market.

Control System – Architecture

The control system architecture of a SmartGrid must be flexible, expandable, to be

opened to meet future needs.

The Multiagent Platform (software agents) must have:

autonomy,

proactivity,

social ability.

Control System – Architecture

The software agents are:

MGCC (MicroGrid Central Controller)

SC (Source Controller)

LC (Load Controller)

MGCC

LCSC

Distribution Management System (DMS)

Control System – Communication technology

The control system requires the adoption of telecommunications channels for data

exchange between remote systems.

In a generic communication system structure there are three main node types: the

global network coordinator, the routers/coordinators and the end nodes.

The designed architecture of SmartGrid control system can be of slave-master or

multi-master type.

Control System – Communication technology

At present, the island electric network has two redundant communication

channels, one based on a radio technology, the other on GSM technology.

The SmartGrid project can include other technologies for data transmission, based

on power line communication (high costs for distribution system application) or

wireless technologies (lower impact but significant problem of data security).

Wi-Max is an interesting technology which has the possibility of covering large

distances and mitigation of environmental impact.

Conclusions

The feasibility study of a SmartGrid project for a Mediterranean island poses a

number of challenges and opportunities:

the integration of new technologies and renewable sources in the existing system;

the reduction of island dependency and of the pollution emissions;

the increase of intelligence and automation level;

the improving of system operation (power quality, minumum losses, etc.).
