Abstract

Conventional grid extension has been the leading mode of electrification in India. A number of remotely located villages in India are yet to be electrified by developing renewable energy based mini grids at remote locations to meet the energy demand. By which, we can utilize renewable sources of energy. The mini grids are profitable in remote areas to provide sustainable, reliable and cost effective electricity. This paper identifies the potential applications of mini-grid (MG) in rural electrification. In this proposed model of mini-grid, simulation is used through which solar PV and wind turbines are used to electrify the rural areas. Solar PV is used to generate electricity only in day time so for the continuation of supply to the rural areas, wind turbine is used to generate electricity in night also. Battery has been used for backup for additional requirement of power in the mini-grid system. The proposed model gives the significant reduction in voltage and current harmonics due to the application of diode (neutral) point clamped 11-level inverter by which reliable electricity is produced.
