A micro grid is a localized group of electricity sources and loads that normally operate connected to and synchronous with the traditional wide area synchronous grid (macro grid), as the number of DC-generating renewable energy sources is higher as compared to AC-generating sources, lesser converter units are required. This increases the overall efficiency of DC microgrid. A DC micro grid system is using a power network that enables the introduction of a large amount of solar energy using distributed photovoltaic generation units. This research deals with the design and performance analysis of a DC microgram with battery-super capacitor energy storage system under variable super capacitor operating voltage. MATLAB 9.4 is using to implement the model and analysis.
Keywords: DC, Micro grid, Energy, Battery, Super capacitor
