Multi criteria analysis of multi-sources photovoltaic electrical structures in isolated sites

Abstract

Multi-source photovoltaic system structures, play an important role in photovoltaic installations especially in isolated sites. However, requirements in terms of performance, power availability and lifetime have to meet the consumption requirements for their integration. In this context, authors propose a consistent approach to improve the choice of an adequate electrical topology of a multi-source photovoltaic system located in an isolated site. This approach is essentially performed by applying a multi-criteria analysis based on a comparison study including four criteria. Four different multi-source photovoltaic system structures are compared according to their life-time, power availability, installation complexity and cost. The comparison process is performed by applying the multi-criteria decision method PROMETHEE II.
