Annual Generation and Cost Analysis of Sustainable Nano Grid Design with Wind Solar Hybrid Power Source for Off-Grid Rural Electrification

Abstract

Global electricity demand is expected to rise up to 38,700 terawatt-hour by 2050 which is almost 57% rise from the current demand. Alongside the United Nation’s sustainable development goal (SDG) for 2030 to provide a clean electricity for every individual and to improve the life quality with regular supply of electricity have fuelled the demand for renewable energy sources in off-the grid and grid generation transmission and distribution. The main challenge of rural electrification is the deployment of transmission lines for rural houses that are located miles away. The cost of erection and maintenance, and the losses in transmission networks for rural areas pose a potential threat to the achievement of SDG for 2030. A nano off-grid 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. In this research the electricity power needs of a rural house are analysed and a nano-grid design with hybrid wind solar energy sources to meet the demands of rural household is evaluated. The system is analysed with the wind and solar irradiance factors of Sook a rural area of Malaysia which is in need of such nano-grid design.   The analysis and evaluation in terms of loads, total energy consumption, renewable generation, penetration and battery for backup of the designed nano-grid system provides a promising result that the system provides a sustainable electricity power to meet the demands of rural houses.
