Using state-space representation for the modelisation of photovoltaic systems

摘要

This paper is about the research carried out for a better knowledge of the microfluctuations of functioning parameters following external perturbations among photovoltaic systems. In several cases studied, it is proven that in site conditions, photovoltaic systems are submitted to many external parameters. To establish relations which can determine the importance of the fluctuations of energetic parameters of these systems, we have adopted a state-space representation. This method is useful when one deals with all parameters of a given studied system. As a result, the use of MATLAB software makes it possible to present the evolution curves of the functioning point of the pv-generator when external perturbations happen.
