DC Micro Grid

Abstract

Today, world wide power consumption is increasing day by day due to modernization. Modernization brings automated technology which cause the more power demand. Though we live in developed or developing countries the power demand is not fulfilled. For solution of this situation world wide so many research is going on which helps to improve the efficiency of the devices. As the demand is not fully fulfilled, the idea came that why we are not going for the on site generation with the help of renewable sources. Now, as the AC power system references available we are aware that this type of system has less efficiency, means it has more losses. This losses may be reduced by on site power generation, transmission or consumption. So, why it should not be used at local as DC has less losses level (or for village electrification).Now combining the benefit of the renewable energy and DC bus concept we can satisfactorily save the power by reducing losses and also help to reduce the pollution. This DC microgrid can be connected to the main grid if it is available or else it work in islanded mode for remote village electrification. DC microgrid simulation is carried out with the help of PSCAD software and parameters observed for the practical system.
