B.1.2. Scientific and Technological Aims and Objectives

Key Scientific objectives :
The Scientific objectives are to investigate ways in which a small power network with several microgrids, which
include a significant amount of RES, can be optimally designed, and operated with maximum efficiency, stability
and flexibility. This will comprise seven research themes, namely:
· Research of control technique for the optimization of single and multiple RES sources and local demand.
· Research of key tools and techniques to design and operate microgrids to achieve maximum power,
minimum loss and lowest cost (monetary and environmental).
· Research of novel power electronic topologies for the interface of multiple RES sources to microgrids.
· Research of new on-line system parameter estimation methods, which will underpin control and fault
detection within microgrids.
· Research of novel power electronic topologies and control techniques for the interface of small microgrids
to transmission systems.
· Research of new supervisory control techniques to allow small microgrids to operate with the power utility
so as to manage the power flows within each microgrid and with the main supply.
· Research of autonomous control techniques to develop RES interface devices critical to the development of
stand alone power quality improvement units for stabilisation of the local grid supply – the Internet
Model Network.
The output of the scientific work will be also materialised into different tool boxes available for future
usages.

Key Technological objectives :
Enhanced/Improved Development of
· Toolboxes usage and incorporation of all the scientific results on the technological system (in particular the
microcontrollers of the multi-input converter)
· Prototype of a multi-input power converter (MSC) to interface RES of different nature on the grid
complying with power quality/EMC issues.
· Development of all accessory devices for the RES and storage elements
· Development of a low power (<10kW) stand-alone PV and wind grid connected system with a common
DC bus and the multi-input power converter.
· Development of a low power fuel cell system, with its own electrolyser and RES source for H2 production

Tests – Metrology-Energetic objectives:
A real-scale show-case: Environmental sensitivity & Islanded holiday resort
In compliance with the issues of the “Work Programme” – “Integrating and strengthening the European Research
Area”, Thematic Priority 6.1, “Sustainable Energy Systems“, in particular with activity code SUSTDEV-1.1.2,
6.1.3.1.1.2 “Large-scale integration of renewable energy sources into energy supplies”, 2 clearly defined
geographical area has been identified, one is the island of Favignana (Trapani), Italy, off the western coast of Sicily
in the Egadi islands and an stand-alone industrial area in Slovenia near Maribor The assessment of the reasearch
objectives above will be therefore performed in these two areas within the local electrical grid with the objective of
integrating RES and efficient demand in the local grid. This will involve the local utility who is a partner of the
project.. The island of Favignana has been chosen for its characteristics of being a holiday resort island like many
small Mediterranean islands with which it shares such features as:
1. small population in winter and significant increase in summer.
2. lack of electrical connection with the continental utility, with resulting local weak grid.
3. oversize of the conventional fuel based generation system to match the summer energetic demand.
4. large differences between summer and winter electrical energy demands.
5. significant availability of wind and solar resources.
6. constraints on environmental issues which require low pollutant emissions and low aesthetical impact.

The energetic objective is the improvement of the performance of the energy system for the existing community
of Favagnana, aiming to improve the sustainability of their energetic system with significant increase of the
percentage of RES so as to ensure both the stability and power quality requirements.

The partners will develop these themes through a series of interlinked research and development programmes. The
overall project aim will be addressed through the specific technological objectives.
