This paper describes the detailed design, analysis of energy dip in solar PV based centralized DC micro grid in rural electrification. Based on the technical and environmental benefits of the renewable energy related solar PV systems are discussed in this paper comparison between the three types of microgrid systems is presented. In this work the consumption of load is about 4.5kWh including the Home load and water pumping system. The estimated required Components such as solar PV Panel, charge controller, battery, distribution system is considered for DC micro grid. further, the voltage dip and Energy drop calculations are presented. The analyzed three architectures are simulated in MATLAB/SIMULINK for power loss and results are presented.
