Abstract
The current paper presents the simulation of a PV-Generator-Wind hybrid power
system to electrify University of Ilorin E-Library using HOMER (Hybrid Optimization
of Multiple Energy Resources) software. Different performance analysis such as
optimization and sensitivity is carried out by the software. Environmental and
economic analysis is used to discuss the sustainability of the hybrid power system.
Results from the analysis revealed that the hybrid system consisting of an 8.33 𝑘𝑊
photovoltaic (PV) panel, 6.5 𝑘𝑊 diesel generator, 6 kW wind turbine, a 6 𝑘𝑊
converter and 10 batteries is the optimal system in terms of Net Present Cost (NPC),
Cost of Energy (COE), Initial Cost and Operating cost The system has NPC, COE.
Initial Cost and Operating cost of US$58,404, US$0.358kWh, US$44,876 and
US$1,046 respectively which is better than a diesel system which has a Net Present
Cost of 𝑈𝑆$ 80,256 and a Cost of Energy of 0.492 𝑈𝑆$/𝑘𝑊ℎ𝑟. Results show that the
hybrid system emits 2,104.35kg/yr of carbon dioxide (CO2), 5.19kg/yr of carbon
monoxide (CO) and 4.23kg/yr of sulphur dioxide (SO2) while the diesel system emits
20,115.90kg/yr of CO2, 49.65kg/yr of CO and 40.40kg/yr of SO2. The emission of the
hybrid system is an order of ten lower compared to diesel system indicating a lower
greenhouse effect. Sensitivity analysis on diesel price and wind speed shows that with
increasing diesel price, the NPC and COE the hybrid system increases whereas with
increasing wind speed, 𝑁𝑃𝐶 and 𝐶𝑂𝐸 decreases. These results serve as a reference
point for the design and installation of hybrid system for the building.
