MODELING AND SIMULATION OF WIND-SOLAR HYBRID ENERGY SYSTEM FOR POWER SUPPLY TO FACULTY OF ENGINEERING TEACHING WORKSHOP IN UNIVERSITY OF MAIDUGURI

Abstract

Modeling and simulation of a PV-Wind hybrid electric power generation system is presented in this paper. The system generates power from wind and solar energy sources and also supplies power to the Faculty of Engineering Teaching Workshop, University of Maiduguri, Nigeria. Ten years meteorological data (wind speed and solar irradiation) for Maiduguri was collected from the National Metrological Agency (NIMET) and analyzed using statistical and simulation software (HOMER). Theoretical models for predicting the electrical power generation potential of the hybrid system was developed and the wind and solar energy potentials of the desired site was investigated and analyzed. According to the results obtained through the analysis, the site has abundant solar energy and wind energy potential, about 2-5MWh/m 2 /yr of electrical power can be generated by using the hybrid system under ideal condition. The electric load of the workshop obtained from the energy audit carried out was about 370kWh/day and the scaled peak load is 140kW. The modeling, simulations and design has been carried out using the HOMER software based on the promising findings of these two renewable energy resource potentials. The software generates the simulation results which are lists of feasible power supply systems have been and arranged in ascending order according to their net present cost.
