Sustainable Nano Grid Design with Solar Wind Hybrid System for Off-Grid Rural Electrification

Abstract

— Recent trends of global electricity demand shows a sharp escalation and is expected to reach
38,700 terawatt-hour by 2050 which is double the times of current demand. To meet the escalating demand
alongside with the United Nation's Sustainable Development Goal 2030 to provide a clean electricity for
every individual, the potential of renewable energy sources is explored in in off-the grid and grid generation
transmission and distribution. Adversely the cost of commissioning and maintenance, the loss in
transmission networks for rural electrification pose a threat to the achievement of SDG 2030. A nano offgrid design with hybrid renewable energy sources to meet the demands of individual household will be an
alternate and efficient solution to provide a clean and uninterrupted power supply for rural homes. This
research proposes an architecture of Sustainable Nano Grid Design with Solar Wind Hybrid System for OffGrid Rural Electrification. The proposed architecture is designed to be an affordable and easy to deploy
system to meet the demands of a rural household. The power generated from designed solar power system is
25.44 Watts and the designed wind turbine system is 4.1 W which was adequate enough to meet the
demands of a rural household with 10 to 15 kWh per month and urban household with moderate
consumption. The system tested in Sook a rural area of Malaysia which needs such nano-grid design have
been consistent enough to provide an uninterrupted power supply for the rural household.
