Application of the multi-criteria analysis method Electre III for the optimisation of decentralised energy systems

The optimisation of decentralised energy systems has to integrate a series of factors, by implementing an approach based on interdisciplinary comprehension. There are technical, financial, environmental and social conditions that determine the selection and dimensioning of energy systems, particularly if these aim at covering the demand of remote regions by utilising renewable energy sources. Such a study requests the overall consideration of the local geological, morphological and climatic conditions, the capacities of the networks, and also the inclusion of the economic and social limitations, an approach that leads to a number of alternative solutions. The application of multi-criteria analysis can integrate the various aspects into a uniform evaluation procedure. This paper discusses the results of a study on determining the achievable penetration of renewable energy sources into an insular system for the purpose of electricity generation. The multi-criteria analysis method Electre III was implemented for this purpose. The research relies on data produced within the framework of the SEDEPIC project, financed by the ALTENER II/DG XVII programme. (C) 2006 Elsevier Ltd. All rights reserved.
