Feasibility Study of Renewable Energy Resources and Optimization of Hybrid Energy System of Some Rural Area in Bangladesh

Abstract

Currently some rural areas of Bangladesh are powered by diesel generators with fuel. To reduce dependence on fossil fuel and improve power system, the government is planning to enhance locally available renewable energy for power generation. Optimization of renewable hybrid energy system looks into the process of selecting and combining the best types of components and their sizing with appropriate operation strategy. This work is designed to presents an optimized technique of a multi-source hybrid energy system which includes renewable energy resources such as biomass, solar radiation as a primary resources and a battery tank which has been used to cover the emergency load demand and a diesel generator for backup. The HOMER software was employed to do the simulations for optimization of hybrid energy system to find out the finest, cost effective and environmentally viable energy system. A detailed feasibility study and techno-economic evaluation of a renewable solar–biomass hybrid system analysis, description and expected performance of the proposed system were presented. The developed biomass / solar / diesel hybrid energy system can supply electricity to the region under consideration at hourly average of a typical day of approximately 11KW. The optimal operation shows that the Cost of Energy (COE) of the system is $ 0.077/KWh where the quick rental power plant in Bangladesh can provide electric power at a rate of $ 0.097/KWh. Finally, a performance analysis on its load consumption and renewable energy resource was performed to evaluate the economic analysis and identify which variable has the greatest impact on the PV system.
