Objectives: The main target of this WP is to design and optimise the management of the distributed generation from
multiple Renewable Energy Sources (RES). In particular it consists in designing, realising and implementing a multiple
RES supply combining a Fuel Cell, a wind generator and a PV array which will then be controlled through the
development of intelligent systems for distributed and co-ordinated control of converter-interfaced renewable generation
units, with particular reference to each microgrid of Favignana...

Task 2.1: (11 and 17 month) Design -implementation: designing, realising and implementing a multiple RES supply
combining a Fuel Cell, a wind generator and a PV array will be developed together with new control strategies for the optimal
exploitation of the single RES generation systems. The envisaged RES system will be of about 30kW and will be composed
of -RES units (Fuel Cell unit, PV unit, wind generator unit) ---A set of super-capacitors as electrical storage system
Static converters for each unit and from the RES system to the grid (DC-AC, AC-DC, DC-DC) ----A DC load (PV supplied
electrolyser for the FC ------- A Reformer for the production of H 2 -----Signal processing system for the optimal energy
management and control All the above elements and control strategies will be experimentally implemented on properly
devised test setups. The study will focus on the on-line maximum power point tracking (MPPT) for photovoltaic and wind
generation systems and the fuel cells. With this regard, proper cost functions for the optimization of each RES unit will be at
first defined.

Task 2.1: (17 and 23 month Cost functions: different cost functions will be defined which describe:
the relationship between the maximum power which can be obtained by the contemporary control of all RES units and the
different electrical, chemical ormechanical values of the single RES.
the relationship between the overall cost of energy production with all RES generators and the different electrical, chemical or
mechanical values of the single RES.
the relationship between the overall power losses with all RES units and the different electrical, chemical or mechanical
values of the single RES.
On this basis, suitable control algorithms, which guarantee maximum/minimum cost operation of each generation unit, will be
developed and experimentally implemented on properly devised test setups.
At the same time, the issue will be to develop a suitable driving strategy of the MSC which, according to the chosen topology,
ensures the design requirements in terms of power quality/EMC issues. These techniques will be experimentally verified on
properly devised test setups, employing also the Electromagnetic Compatibility laboratory with semianecoic chamber and the
GTEM cell at ISSIA-CNR Palermo.
The performance objectives are:
•Ratio between the performance, in terms of overall generated power or overall power losses, obtained with
o the proposed control strategies and with the classic ones for each RES generation system.
o with the proposed distributed generation systems from multiple coordinated RES and those obtained in the existing
grids both without any RES sources and with the same RES sources without any intelligent coordination.
• Ratio between the power quality/EMC performances indexes obtained with the proposed distributed generation systems
from from multiple RES and those obtained in the existing grids both without any RES source and with the same RES sources
without any intelligent coordination.
• Ratio between the performances of the proposed distributed generation systems from multiple RES and the corresponding
ones of the existing systems in compliance with the EMC European Directive 2004/108/EC and the standard IEEE 519
Particular to the maximization of the generated power, the minimization of the overall losses and the optimal exploitation of
the system profitability. New control strategies for the optimal exploitation of the single RES generation systems will be
developed and tested experimentally, with particular regard to photo-voltaic, wind and fuel-cells based systems. These control
strategies will be developed firstly considering each single RES source individually and then taking into account the optimal
exploitation of all RES sources supplying simultaneously the input of the MSC (Multiple Source Converter).
Control strategies for the optimal dispatch of the energy coming from the input RES sources will be developed
