This paper takes a cursory look at the problem of inadequate power supply in the rural healthcare centres of a developing country, specifically Nigeria, and proffers strategies to address this issue through the design of hybrid renewable energy systems combined with the existing unreliable grid in order to meet the healthcare load demand, thus ensuring higher reliability of available energy sources. The simulations, analysis and results presented in this paper are based on meteorological data and the load profiles of six selected locations in Nigeria, using which hybrid grid-connected systems integrating diesel, solar and wind energy sources are designed with configurations to give optimum output. The optimised design configurations in the considered case study, Ejioku, Okuru-Ama, Damare-Polo, Agbalaenyi, Kadassaka and Doso, produce very low energy costs of of 0.0791 /kWh,0.115/kWh, 0.115 /kWh,0.115/kWh, 0.0874 /kWh,0.0754/kWh, 0.0754 /kWh,0.0754/kWh, 0.0667 /kWhand0.0588/kWh and 0.0588 /kWhand0.0588/kWh, respectively, leveraging solar and win...

Rural electrification improves the quality of life and wellbeing of the rural communities. Diesel generators and woods are the main source of energy for the rural dwellers who are not connected to electricity grid, these sources of energy are not cost effective and are detrimental to the community health due to the release of gaseous pollutants from these sources of energy. Therefore, the use of renewable energy sources as an alternative source of energy for the rural communities become imperative in order to improve socioeconomic activities of these rural communities. In this study, a feasibility analysis on the use of a hybrid solar-wind-battery-diesel system for providing electricity to a rural secondary school is investigated. A village (Moriki) in north western Nigeria is selected for this study with the aim of taking the same study to other parts of the country. A simulation software Hybrid Optimization Model for Electric Renewable (HOMER) is employed to carry out the feasibil...
Analysis of an optimal hybrid power system for an off-grid community in Nigeria
International Journal of Energy Sector Management, 2019
Purpose This study aims to analyze the effects of variations in annual real interest rates in the assessment of the techno-economic feasibility of a hybrid renewable energy system (HRES) for an off-grid community. Design/methodology/approach Hybrid Optimization of Multiple Energy Resources (HOMER) software is used to propose an HRES for Abadam community in northern Nigeria. The HRES was designed to meet the basic needs of the community over a 25-year project lifespan. Based on the available energy resources in the community, photovoltaic (PV), wind turbine, diesel generator and battery were suggested for integration to serve the load requirements. Findings When the annual real interest rates were taken as 10 and 8 per cent, the total amount of total energy fraction from PV, wind turbine and the diesel generator is 28, 57 and 15 per cent, respectively. At these interest rates, wind turbines contributed more energy across all months than other energy resources. The energy resource dis...
