Abstract
Various statistics indicate that many of the parts of India, especially rural and island areas have either partial or no access to electricity. One of the foremost reasons for this is the wide expanse of which the power producing stations and the distribution hubs are located from these rural and remote areas. This emphasizes the significance of subsidiarity of power generation by means of renewable energy resources. Although in current energy production scenario electricity supply is predominantly by alternating current, most of the everyday utility devices like cell phone chargers, computers, laptop chargers etc. all work internally with DC power. The number of intermediate power conversion stages are significantly reduced by supplying DC power to these loads. The paper also states other works that prove the increase in overall system efficiency and thereby cost reduction. With an abundance of solar power at disposal and major improvement in the area of power electronic converters, this paper suggests a DC grid that can be used by a household in a remote or rural area to power itself utilizing Solar PV. The work was designed for a household which is not connected to the main grid and was successfully simulated for several loads totaling to 250W with the help of an isolated flyback converter at the front end and suitable power electronic converters at each load points. Maximum extraction of usable energy from renewable sources at a residential and commercial level is intended with the suggested DC topology. © 2017, Institute of Advanced Scientific Research, Inc.
