Design and Analysis of Low Voltage DC Grid for Domestic Supply

Niharika Yadav, Shailendra Singh, Rajat Sahu, Pushpam Pushpam

Abstract


The fast development of DC power based devices has led to increased involvement of AC to DC converters. A large scale research work is being conducted on increasing the efficiency of these converters to save energy. But DC microgrids are significantly more energy efficient when implemented with distributed generation or on-site generation from photovoltaic panels, wind turbines, fuel cells or micro turbines. This paper discusses the advantages and disadvantages of DC for a domestic household and includes a comparison between the outputs derived from the power supplied to the DC loads from low voltage DC grid and AC power supply under same operating conditions. In distribution system the technical and economic benefits of DC represents an alternative to the application in AC system. DC can be easily stored in batteries just with the use of voltage regulator thus considerable amount of power can be saved by the use of DC grid.

Keywords: DC micro-grid, DC-DC converter, efficiency
