Investigations on injection of solar wind power into 380 vdc bus using single switch converters for tight voltage regulation

Abstract

The extension of the power system technology to the DC microgrid newlineis being studied in the literature as part of smart grid research programmes, newlinedistributed generation using renewable sources, and utilization of electronic newlineloads with DC power. A DC microgrid can run independently of the main newlinepower grid by generating and utilizing its own DC power. The most common newlineways of generating power for DC microgrid are with solar panels, wind newlineturbines and fuel cells. The excess energy is stored either in batteries or is newlineinjected into the main grid. DC distribution provides efficiency improvement newlineby reducing energy conversion stages for DC based generations and loads. newlineThe origin of DC microgrid is in the telecommunication sector. The newlineincreasing power density of equipment motivated the move to a higher DC newlinevoltage, between 350V to 400 V. DC microgrid supplying DC electronic newlineloads is advantageous since it interfaces renewable energy sources to the newlineelectrical grid system. Globally, the data center market aims to standardize its newlinesystem in two voltages: 380 and 400 VDC. newlineInterfacing distributed renewable energy generators newline
