Battery energy storage systems (BESS) can be used in electrical distribution grids to avoid violations of grid’s operational limits and to reduce residual photovoltaic (PV) peaks. For customers such as households with PV systems, the use of BESS is particularly interesting, as they can increase their electrical self-sufficiency degree (SSD) and reduce the costs of their electricity purchasing. This paper deals with the optimal sizing of BESS for residential buildings with PV. The analysis considers 175 buildings located in a real suburban neighborhood, consisting mainly of detached and semi-detached houses.
