HIGH RENEWABLE ENERGY SOURCES INTEGRATION INTO THE ISLAND ELECTRICAL GRID

Develop a knowledge and a control of the global energy system (management of the intermittent aspect of the solar energy source and sizing the system) as well as the technology based bricks.

The components of an energy system based on hydrogen technology are today in a development phase. To test them on a study and experimental platform must allow us to validate the present and future development.

The R&D Platform of Vignola – Ajaccio (Corsica) must allow us to develop ant to set-up models, to quantify and to propose optimized architecture of adapted system based on an association between RES and Hydrogen

Main objective is to control the system power output on the grid during critical hours : peak load shaving

An homothetic approach is made, downscaling the power requirements from 30 MW to 200 kW

Primary power is supplied by a 550 kWp PV plant

Experiment the association of a photovoltaic array and an hydrogen chain in an electrical grid connection condition (Budget of about 18 M€ over 5 years)

Presentation of the ProjectObjectives

System optimization is seek through:

The assessment of the storage needs according to the system objectives

The definition of the more adequate working profile for the electrolyser

The use of an H2/O2 FC system

The use of an HP PEM electrolysis system

Heat recovery and storage

Water management

Development of PEM systems

Overall process design

Energy storage is designed to allow the fuel cell system to supply electricity while a 3.5 days blackout occurs

Phase I: FC system nominal power 50 kWeElectrolysis nominal flowrate < 10 Nm3/hPhase II:FC system nominal power 200 kWeElectrolysis nominal flowrate 40 Nm3/h

Different control strategies must be set up in phase I and phase II

Presentation of the ProjectFirst scientific results

One common techno-economic tool is being developed by the partners (Hélion, University of Corsica, CEA)

Integration of each partner competencies in order to develop the most accurate model and to integrate technological advances realized in the many fields involved.

Two levels are implemented in the soft Economic level: macro economic assessments (cost of grid electricity, interest rate, etc.)

Techno economic assessments (equipment costs, lifetime, etc.) Design level: Which combination of equipments match the objectives of the hybrid system?

1) Techno-economic sizing tool

Status: beta version of the soft is in use. The tool will now be compared to real-life through the demonstration projects

For each kind of application family, typical process and electrical design will be studied and classified in order to set up an engineering reference library

2) Electrical & process library

Status: referencing project starting December 2007

The R&D project of Vignola-Ajaccio :

- The project the more important with the label of the Capenergies cluster

- An exemplary project in terms of partnership public-private

- An emblematic project for Corsica towards the energy challenges of the Island and for other islands

- Consideration of all the environmental aspects

Today, the main questions are treated what allows to envisage a start-up of the project and a respect of the terms.

Scientific, social and economic effects are expected

CONCLUSION

17 17HELION

The objective of the platform is to allow a controlled injection of electricity from RES into the electricity network.

The main mission fixed at first is to support the electricity network, essentially on one of these meshes, in view to shave the peak load, and to contribute to achieve an high rate of integration of RES (> 20%).

The association « RES/H2/FC » could permit to exceed the technical limit of 100 MW of RES. The objective is to develop a system and a methodology in view to improve the management and the stabilization of the electrical grid.
