Techno-Economic and Environmental Analysis of Renewable Energy Integrated System for Rural Electrification in North-Eastern Region of India

The objective of this research is to analyze the techno-economic and environmental feasibility of an integrated system based on renewable energy such as SPV(solar photovoltaic), wind turbine(WT), biogas generator, micro hydro turbine(MHT) and hydro kinetic turbine(HKT) to provide electricity to a mountain village in the state of Assam, India. Simulation and optimization process are performed for ten categories of integrated renewable energy system (IRES) using HOMER Pro software. Each IRES is designed based on the optimal component size, technical performance, economic and environmental impacts. The ten IRES systems are evaluated with techno-economic-environmental key factors such as renewable fraction (RF), total net present cost (TNPC), levelized cost of energy (LCOE) and greenhouse gas(GHG) emission. From the simulation results the diesel‐biogas-battery integrated system has demonstrated to be the most feasible in terms of technical performance, economic and environmental impact, while the diesel‐hydro kinetic turbine-battery integrated system has demonstrated to be the least feasible system. Furthermore, a sensitivity analysis has been performed to determine the most sensitive parameter of the diesel‐biogas-battery integrated system
