Abstract


This research paper centres on the optimum design, simulation and performance investigation of a micro-power system for off-grid locations. The objectives are to verify the monetary cost, power supply reliability and ecological benefits of the addition of wind turbines and solar photovoltaic array to a diesel generator system for electric power generation in remote sites. The optimum design configuration of the hybrid micro-power system was established on the basis of energy-balance estimations using the Hybrid Optimisation Model for Electric Renewable (HOMER) software. Simulations were carried out for a remote site in Maiduguri (lat. 11°50.9′N and long. 13°9.2′E), with a population size of 50 households, using the estimated electric load profile and 22-years meteorological data sets collected for the studied area. The results showed that a micro-power system made up of 75kW wind turbine, 46.7kW of solar photovoltaic generator and a battery bank capacity of 420.34kWh (24V, 17,514Ah) can reliably satisfy the electric power demands for a remote site at Maiduguri (with a daily peak and average consumption of 97.74kW and 563kWh/d respectively). Moreover, a monetary cost saving of over 79% in addition to a reduction of 5,125 kg/y of CO2 emission per household energy consumption can be achieved compared with the traditional diesel-only power generation system.
