Techno-economic sizing of off-grid hybrid renewable energy system for rural electrification in Sri Lanka
2015
Abstract Off-grid hybrid renewable-energy-based power systems for rural electrification have become an attractive solution for areas where grid electricity is not feasible. Hybrid energy systems use several energy technologies, and the selection of proper technologies with optimum sizing of the selected components has become very important. The objective of this study has been to investigate the optimum configuration of a hybrid system that can supply electricity to a rural community in Sri Lanka. A rural village in Siyambalanduwa (Sri Lanka) comprising approximately 150 households with a resultant daily electricity demand of 270 kWh and a nighttime peak of 25 kW has been studied. This regi…
Design of Photovoltaic System for Rural Electrification in Rwanda
2017
Master's thesis Renewable Energy ENE500 - University of Agder 2017 In this century of accelerated development in various domains, some African countries are still facing a challenge of lack of power due to its scarce in some places, where by the main source of power (generation of electricity) is hydro since thermal and fuel are still on a small scale. This problem results in less productivity and economic decline of some countries like Rwanda which is among African countries that are at a very high speed in development, the grid lines from distant places are stack and they are few compared to the need of electricity in all corners of the country, especially in rural areas whereby each hous…
A Review of Nanogrid Technologies for Forming Reliable Residential Grid
2020
Nanogrid is a scale down version of Microgrid. Nanogrid (NG) forms the residential grid with the sources like solar PV, diesel generator, fuel cell and battery based energy storage as a backup for supporting autonomous operation of NG. This paper is focused on portraying the importance of NG for rural electrification of India. The source-load coordination in the NG will ensure the optimal power flow in the grid. This paper has reviewed two most important control techniques i.e. centralized and decentralized for ensuring source-load coordination in the NG. Interfacing converters are the important constituents of NG to dispatch the power from intermittent renewable energy sources to load. Dep…
Hybrid Energy System for Rural Electrification in Sri Lanka: Design Study
2015
Off-grid hybrid renewable energy based power system for rural electrification has become an attractive solution for areas where grid electricity is not feasible. Depending on the availability of the resources, single energy source or a combination of several sources, including an energy storage system is used in an off-grid hybrid energy system. As there can be several candidates, the optimum sizing of the components against resource potential, cost and reliability is a vital issue. This chapter presents a study of optimum sizing of a renewable sources based off-grid hybrid energy system that is designed for electrifying a rural community in the Siyambalanduwa area in Sri Lanka. The communi…
