Some small territories, such islands, actually experience a high penetration rate of PV inside a small electricity grid. In this context, the variability of the PV output is an issue for the supply-demand balance. The spatial and temporal smoothing of the variability of the PV production is an important information for the grid operator.Previous works on this topic were mainly done for large-scale continental grids. They pointed out the relation between the production variability with the number and the dispersion factor of the PV systems. This paper presents an analysis of the variability of PV output for a small insular territory: Reunion island. This island has a large variety of microclimates and a strong penetration rate of PV (almost 30% of the installed power). For this little grid, the spatial and temporal effects on the variability of the PV output differ slightly with previous works.
