Implementation Methodology of Integrated Renewable Energy System Modeling for Off-grid Rural Electrification: A review

The various needs of human domiciled in the isolated rural areas can be fulfilled using locally available renewable energy (RE) sources especially when a grid extension becomes economically unviable. The off-grid rural electrification using single RE source may not be economical and reliable due to the intermittent operating characteristics of the major RE sources. The integrated system designed using two or more indigenous RE sources along with the energy storage device can overcome the demerits of single RE source-based system. This paper aims to present a review on implementation methodology of the integrated renewable energy system (IRES) modeling for off-grid rural electrification. In this context, a review on the earlier studies conducted on the IRES for off-grid rural electrification has been carried out, and the discussion on the various configurations, design approach, and the steps involved in modeling methodology of the off-grid IRES has been presented, which can be useful for planning the off-grid IRES to electrify the remote rural areas. This study will be useful to the researchers working on RE sources based stand-alone power generation for remote rural areas.
