Abstract: This paper discusses and quantifies the different benefits for PV systems of a hybrid AC-DC in-building grid typology compared to a traditional AC in-building grid typology. A common DC bus is used to interconnect the PV system and the EV charging infrastructure. The possibilities and related advantages for PV systems to distribute the electricity more efficiently in larger buildings, are discussed. A representative apartment building, equipped with a PV system and electric vehicle (EV) charging infrastructure, will be used for this study. This paper does not only discuss the impact of hybrid AC-DC grids on the energy efficiency and the reduction in cable and converter losses. Also, the impact on peak powers, both demand and injection, total energy exchanged with the low-voltage distribution grid, voltage magnitudes, voltage unbalance and cover factors are discussed.
