Water Supply in Rwanda Use of Photovoltaic Systems for Irrigation
2015
The current energy situation in the world where most of the energy needed is generated from non-renewable sources such as fossil fuels is no longer sustainable. During few years, nonrenewable sources have become an interesting solution to provide energy to areas with small needs of electricity, rather than using non-renewable sources. Therefore, this project has pursued to implement photovoltaics panels to supply energy in a rural region in central Africa, contributing to the development of the area and proving that this technology is viable to pump water for irrigation instead of the conventional electric grid. A rural area between Kidogo Lake and Rilima town, in Bugesera district of Rwand…
Offshore Wind Power Technology Development and Testing of a Downscaled Pitch Controlled Wind Turbine
2015
Masteroppgave fornybar energi- Universitetet i Agder, 2015 The energy demand of the world increases day by day, and at the same time people become more aware of the impact fossil energy sources have on the climate. This leads to an increased focus on renewable energy sources, such as wind power, which has been pointed out as an important contributor to the production of renewable energy. In recent years the focus has shifted from land based wind farms towards the possibilities of the large energy potential that exist in the open ocean along the coast line. The background of the thesis is motivated by the increased focus on offshore wind power technology. State of the art technology in the f…
Fundamental Analysis of Triple Layer Area Decoupled Photovoltaic Modules
2015
Masteroppgave fornybar energi- Universitetet i Agder, 2015 The main objective of this work is to analyse the area decoupled triple layer photovoltaic module, by application of voltage matching under AM 1.5 light spectrum. This includes, calculation of detailed balance efficiency, calculation of optimal numbers of cells in each layer to achieve voltage matching comparisons with independently operated triple layer stack. Performance change under various different scenario is also observed. We have used MatLab programing software for all our analysis i.e., plots and calculations. At first we investigated the optimal efficiency of independently operated cells of triple layer stack. Then applyin…
Development and Electrochemical Evaluation of Tape Cast Substrates for SOFC Single Cells
2013
Masteroppgave fornybar energi- Universitetet i Agder, 2013 As a means to reduce the solid oxide fuel cell material cost and make it more adapted to other fuels, titania as a candidate catalyst material has been investigated. A low-cost, high precision, self made tape casting system made it possible to fabricate thin films by the tape casting method. Substrates for SOFC single cells were manufactured through experimentation and optimization of slurry recipes for tape casting. The produced substrates were micro-structural analyzed by using an AFM, and evaluated with the use of EIS. The study shows that it is possible to fabricate standalone titania substrates. And the structural analysis and …
Impact of High Penetration of Electric Vehicles on Low Voltage Network Stability and Role of Managment Programmes for Electric Vehicle Charging
2015
Masteroppgave fornybar energi- Universitetet i Agder, 2015 The number of electric vehicles (EVs) have increased in Norway over the last couple of years. Low emissions and reducing petroleum dependence are some of the advantages achieved by using EVs. This master thesis presents the impact of high penetration of EVs on a low voltage distribution network. Uncontrolled charging patterns of EVs will likely stress the distribution network and could cause power outages, voltage fluctuations, thermal stress on the lines and harmonic pollution. As an alternative to grid reinforcement, smart load management (SLM) and demand side management (DSM) were introduced for coordinating the charging of large…
Analysis of Power System Options for Rural Electrification in Rwanda
2015
Masteroppgave fornybar energi- Universitetet i Agder, 2015 The development of modernized energy system for developing countries especially in rural areas is constantly a considerable problem to energy utilities. The progressive use of diesel generators in rural areas as main source of electrification is continuously becoming unsuitable because of the following reasons; the diesel generator requires the fuel at every single second of operation and the maintenance of every time is needed and it is very important to worry about the instability of power generated by those generators and the accessibility of fossil fuels is still a challenge for some communities. Whereas the introduction of new …
