Modeling A Simple Dc Micro Grid Using Solar Panel, Battery Storage And Backup Generator Arrangement And Do Cost Benefit Analysis For Supplying Isolated Dc Electric Power To Rural Village In Navamalai, Aliyar Region, Tamilnadu, India (original) (raw)

This paper is written with respect to the modeling of DC Micro grid using solar panel and backup generator by applying Hybrid Optimization Model for Electric Renewable (HOMER) pro software tool to supply cost effective and reliable independent power to a limited number of rural communities that used specific type of DC loads. The model area was selected ahead of the modeling and analysis process and indicated on Map using the HOMER pro area search facility. A generator that used Methanol was added to the system to enable the designed model more reliable. The contribution of each source type was analyzed in detail in the analysis section of the paper. It showed that the contribution of the generator is insignificant as compared to the contribution of the solar panel in supplying the loads. This paper mainly focused in analyzing the primary and secondary simulation data outputs by considering the base and current model systems. The base model system contained the solar panel and battery storage only. Whereas the current model system contained the solar panel, battery storage and generator. The optimal operation shows a unit cost of Rs. 0.125/kWh with the selected energy system with 100% renewable energy contribution eliminating the need for conventional generator. The developed model helped in sizing the components of the energy system and decides the optimal combination for electrification of the rural village in Navamalai, Aliyar region, Coimbatore District, India by DC power. Final conclusion reached based on the identified optimal model and analysis.
