Effects of the Operating Point of Photovoltaic Strings on Sizing of DC‐ and AC‐Connected Energy Storage Systems for Power Smoothing

Advanced Energy and Sustainability Research, Volume 6, Issue 10, October 2025.
This study is based on measured current–voltage curves of a 23 module photovoltaic (PV) string. The results of the study show that, in practice, following the maximum power point (MPP) closest to the nominal MPP voltage instead of the global MPP has no major effect on sizing of energy storage systems for power smoothing of PV strings.
