Optimization of Hybrid Renewable Resources using HOMER

Abstract

The demand of electricity is increasing day by day throughout the world. Due to limited amount of fossil fuel it is important to design some new non-renewable energy systems that are able to decrease the dependence on conventional energy resources. A hybrid off-grid renewable energy system may be used to decrease dependency on the conventional energy resources. Optimization of hybrid system is a process to select the best combination of component and there cost that are able to provide cheap, reliable and effective alternative energy resource. In this paper photovoltaic system, wind turbine, diesel generator, battery backup and converter have been simulated and optimized for Measurement & Instrument Laboratory in Electrical Engineering Department of Madan Mohan Malaviya University of Technology at Gorakhpur, India. In this system, primary source of power is solar photovoltaic system and wind turbine whereas diesel and batteries are used as backup supply.  HOMER software has been used to simulate off-grid system and it checks the technical and economical criteria of this integrated system. The performance of each component of this system is analyzed and finally sensitive analysis has been performing to optimize the hybrid system at different conditions.
