Techno-economic and environmental evaluation of demand side management techniques for rural electrification in Ibadan, Nigeria

Abstract

According to the United Nation Development Programme, access to modern low-cost energy systems in developing countries is important in the realization of the globally agreed developmental goals, as well as the Millennium Development Goals, and sustainable development, which would assist in the reduction of poverty and to improve the conditions and quality of life for the greater part of the world's population. Planners have suggested hybrid energy system for the electrification of rural areas worldwide. This study investigates the techno-economic and environmental effect of applying demand side management (DSM) activities to rural loads before design and sizing of hybrid energy systems for such community. Iporin a rural area in Ibadan, Nigeria which is endowed with an average daily solar radiation of 3.84 kWh/m 2 /day was taken as a case study. The total daily consumption which was initially estimated as 297 kWh/day after the application of DSM techniques dropped to 130 kWh/day representing a decrease of 56.80 %. Hybrid Optimization Model for Electric Renewables software was used for simulation and optimization purpose. Parameters such as DSM index, net present cost, and emission level were used in determining the effect of the DSM technique. Overall, the DSM activities proved to be more economical and environmental friendly.

Techno-Economic Feasibility of Hybrid Solar Photovoltaic and Battery Energy Storage Power System for a Mobile Cellular Base Station in Soshanguve, South Africa

“…Although the use of solar PVs to power mobile cellular BSs started with second-generation (2G) technology, their utilization is mostly in rural areas where there is no access to the grid system [20]. Nonetheless, the solar PV-powered BS is becoming widely accepted in urban areas as a result of a reduction in OPEX, advancements in renewable energy research, and the viability of new BSs with a low power consumption and that take up less space [21,22]. [23].…”

“…Most generating units worldwide, especially in developing nations, are powered by conventional energy sources . These energy sources have increased the carbon footprint, thereby causing climate change . Thus, there have been several governmental policies, researches, and programmes that are targeted at reducing greenhouse gases (GHGs) released into the atmosphere .…”

“…Access to a reliable power system is crucial to the development of a nation's economy due to its interrelationship with gross domestic product (GDP). 1 Since its product is defined in terms of goods and services, it provides the impetus for economic upturn. The power sector is therefore a substructure on which many economies are built.…”
