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...

The work is about the Development of Hybrid Renewable Energy System for the Electrification of rural areas in cross River State, Nigeria. A Hybrid model comprising Diesel Generator, Battery banks, photovoltaic Panels and wind turbine Generator was proposed to serve remote communities at Yakurr Local Government Area, Cross River State. The human problem of generating individual electricity using private generators at a high cost due to no access to the national grid has been solved. The procedure of this work was the measuring and collection of the basic meteorological data of solar radiation from NASA for Ugep, and then performing components modeling and simulation. Wind speed of 3m/s, regional solar irradiance of 3.697kWh/m 2 /d and total energy demand of 198kwh/d from the rural community were used as input in the study. The method of incremental conductance was used to achieve maximum power output. Comparative economic analysis of Hybrid Renewable Energy System and the diesel generator system was performed. The implementation of the HRES for two weeks cost N42,000 only thus saving the community N365,500. A total of 2,266kWh/d of electric energy was generated as against, 1,890.8kWh/d using generator at a cost of N407,500. Using HRES with a battery bank of high amp-hour capacity for storage is capable of supplying the required electric energy including peak period. Pollutant emissions were reduced due to the penetration of solar renewable energy. An Automatic power transfer Device utilizing voltage monitoring relay was introduced to function only during period of bad weather.
A Study of Wind and Solar Resource Potentials for Hybrid Application in Wachemo University
Annual Research Review Conference Wachemo University, 2014
In this paper assessment of wind and solar radiation potentials of Hossana town (7.580N, 37.880E) is studied using data available from local meteorological stations. The collected data was treated for missing data and inaccuracies. A load model for the main library of Wachemo University was developed. HOMER software was used to study the feasibility of those resources in supplying the developed load model. In the analysis wind turbines, solar PV panels, converters & inverters (inverter chargers), storage battery system and diesel generators were included and an optimal sizing of each component was made. The study proved the existence of attractive solar energy potential with the daily average annual solar radiation being 6.08 kWh/m2/day, which is well better than the country average (i.e. 5.28 kWh/m2/day). Though the wind energy resource in the area is not as attractive as the PV one, the use of a hybrid system, with tall wind turbine stays an option. The optimization result of the hybrid system for the main library of Wachemo University using HOMER shows that though it would be an easy decision to continue with using the power from the central grid with a least cost, the option of applying a PV system even without any additional battery system can result in a 336 kWh energy saving annually with CEO of $0.017 (0.33 Ethiopian Birr). The option of implementing a PV/ wind hybrid system with all components could result in the total grid purchase being lowered by 25% though it is the costliest option.
