Abstract
This paper presents a feasible study to determine the best configuration of a standalone hybrid renewable energy system (HRES) for the University Restaurant (RU) of the Federal University of Pernambuco (UFPE). The proposed work utilizes a hybrid solar-wind system with diesel generator and/or battery backup. The solar radiation and wind data were obtained from NASA surface meteorology and solar energy database. The Hybrid Optimization Model for Electric Renewable (HOMER) software was used to do the simulations and techno-economic evaluation. Many different cases have been carried out to find the optimal configuration based on the net present cost (NPC) and cost of electricity (COE). Results indicated that a system with PV panel, diesel generator, and battery is the most economically viable option. However, the second option was selected, since it is more environmentally correct, with a renewable fraction of 54% of power production, and 16.3% of excess of electricity. The system contains PV panels, wind turbines, diesel generator and a battery bank for backup. It is also economically viable with the NPC of $1,173,037 and a COE of $0.5/kWh. In addition, the result shows that this system reduces the emission of pollutants such as CO2 when compared with the system without wind turbines.
