Smart Power Management for DC Nanogrid Based Building

Nanogrids is a subset of microgrid which is powering a single building or a house. Low voltage DC distribution within building or house structures is called a DC Nanogrid. The DC Nanogrid consists of power converters like Solar PV Converter, Battery Management system (BMS) and an AC/DC converter which draws powers from the grid when renewable and BMS unable to deliver the load demand. DC Nanogrid is a low voltage DC distribution system suitable for residential applications where we can connect DC electronic loads like BLDC fans, Laptop, LED Lights. For the efficient operation of the DC Nannogrid power management with various modes of control is required based on the energy availability from different powering sources and load demand. Smart power management for buildings based on DC Nanogrid is highlighted in this work.
