Paper Details

In this paper DC-microgrid architecture withRenewable Energy Resources is described. Microgrid is a part ofdistribution network embedding multiple distributed generationsystems (mostly non-conventional renewable energy sources likewind turbine, photovoltaic panels etc.) and storage systems withlocal loads, which can be disconnected from the upstreamnetwork under emergency conditions or as planned. Microgrid isdefined as a cluster of distributed generation sources, distributedstorage devices and distributed loads that operate so as toimprove the reliability and quality of the local power supply andof the power system in a controlled manner. The present powersystem is established on AC that provide supply to the AC powermachine, but the new on-going revolution in power electronicsand many smart devices are coming in the list of domestic goods,which are powered by DC. To provide DC, AC supply should berectified and regulated which produce losses. Instead ofrectification a new independent DC microgrid architecture isdesigned to which the DC load can be connected. In this reviewpaper, DC microgrid architecture can be independently poweredby renewable energy resources which can directly generate DCpower. This paper also presents challenges in integration ofrenewable energy sources and their solution of integratingrenewable energy sources utilization.
