ABSTRACT
Abstract Photovoltaic (PV) buildings are increasingly present in urban centers and can generate their own energy becoming independent of the grid, depending on their consumption profile. However, most residential and commercial consumers show their peak demand at night, when there is no photovoltaic generation, needing the electricity grid to meet the demand of these facilities. Peak demand lead to increased costs for these consumers and end up disrupting the power quality of the grid. One possible solution for these listed problems is by applying storage systems to these buildings, which is already being done in some countries and can increase the PV generation. Aiming to seek the state of the art of these systems, this article brings a review of the literature, highlighting the possible modes of operation and a real case of application in PV buildings in the world. Also are described the storage technologies most appropriate for applications in these buildings, highlighting their advantages and disadvantages. It is expected to gain greater knowledge of these systems, in order to overcome the challenges of intermittence generated by renewable sources, enabling the reduction of energy demand costs in these customers so that it can also be applied in the Brazilian scenario.
