• The benefits of hybrid microgrids may be even larger for commercial and office buildings with integrated PV, due to a higher share of dc internal loads and increased self-consumption of PV electricity. PV and battery size are important parameters for the evaluation of hybrid microgrid performance.

• Dc networks are most efficient for buildings with a high degree of autarky enabled by a high share of dc renewable sources.
