Mitigation of the Variability of a PV Fleet via Geographical Dispersion and Energy Storage Systems on the Reunion Island Non-Interconnected Grid

In this paper, the geographical dispersion of PV installations and Energy Storage System (ESS) are studied to smooth PV production on Reunion Island. Despite the small area of the Island, the results show that with dispersion at the total grid scale, the variability driven by weather conditions (unpredictable variability) is almost removed. Then a centralized EES management at grid scale and a few large EES units could mitigate the variability even further with a relative low cost.
