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.Downloads

The journal is currently an open access journal.
The articles receive both rigorous peer-review and expedited online publication.
The journal encourages young researchers to submit their unpublished papers.
The authors retain their article’s copyright.
The authors retain publishing rights without restrictions.
Thus, authors may use their own articles for the following non-commercial purposes without asking our permission (and subject only to acknowledging first publication in Journal of Communications Technology, Electronics and Computer Science and giving a full reference or web link, as appropriate).
Authors cannot submit a manuscript for publication to other journals simultaneously. It is a waste of valuable resources because editors and referees spent a great deal of time processing submitted manuscripts. It is also unethical to republish similar research articles (text/figures/tables) again because journals have limited page space and it most likely violates copyrights which have already been transferred to the first journal. Therefore, all journals require a signed author's copyright transfer agreement stating the originality of the research work submitted through a manuscript. As stated above that authors should submit original, new and unpublished research work to the journal. The ethical issues such as plagiarism, fraudulent and duplicate publication, violation of copyrights, authorship and conflict of interest are serious issues concerning ethical integrity when submitting a manuscript to a journal for publication.
