Abstract:
This study presents biomass gasifier base hybrid energy systems optimization for energy access to a non-electrified village by using HOMER simulation tool. Hybrid energy system consists of two or more renewable or non-renewable source of energy and improves the reliability of energy supply. The case study is considered here for analysis is an un-electrified village Jhawani in Assam to meet the energy needs of the village based on the locally available energy resources. The domestic load requirements includes lighting, fans, television, mobile charging point, water pump for drinking water, etc; community load includes street lights in the village, fans in the community hall and computer for school and commercial loads like lighting in the shop and small scale rural enterprise like rice hulling machine and irrigation for cultivation as livelihood activities in the village. The hybrid energy system uses biomass gasification system, solar photovoltaic system, battery as energy storage to provide electricity when load demand is low and diesel generator as a backup to improve the reliability of the system. The primary objective of the hybrid energy system to provide reliable electricity based on the load and energy requirement of the village. In this study, both off-grid (when grid is not available; present scenario) and grid connected (when grid will be available but not reliable; future scenario of the non-electrified village) is considered. The study presents the analysis of optimal system configurations for different energy and load profiles and for various grid availabilities. The analysis found that the cost of energy generation primarily depends on the load factor. Hence, load scheduling or proper load management is crucial to reduce the cost of energy generation. The optimization result shows that biomass gasifier base grid connected hybrid energy system can provide reliable energy supply to un-electrified villages.
