All of the sophisticated electric applications found in commercial buildings, such as lighting, information technology (IT), and telecommunications equipment, as well as speed-controlled drives in HVAC and ventilation systems, can have an efficient direct current (DC) supply thanks to the use of contemporary power electronics. LED lights and most electronic loads in the built environment are powered by DC power sources. Conversely, the dc nature of LED luminaires leads to large power conversion losses. Typical fluorescent lights, on the other hand, are mostly powered by the ac grid. When using equipment that requires a suitable power supply for high performance requirements, the reduced power supply in AC may cause malfunctions. Because of these demands for great performance, DC was necessary. The inefficiency of AC/DC converters used with LED lighting may be seen as a benefit since LED lights only need DC power. The project being presented would include information on a DC grid that is integrated with solar MPPT units. This grid powers a DC lighting system, a DC electric vehicle charger for a small area, and a DC low power supply for IT infrastructure (micro grid). A physical prototype and a MATLAB simulation would be created in order to validate the results.
