Fremtidig systemjording av regionalnettet i Agder
2018
Masteroppgave fornybar energi ENE500 - Universitetet i Agder 2018 System earthing describes how the neutral of a transformer is connected to ground. If a ground fault occurs, the system earthing is to detect and manage the fault current in such a way that it does not inflict damage on humans or the grid. An increasing fault current in compensated earthed networks have recently started to cause concerns in the Norwegian regional grid. Grid expansions, upgrades in operating voltage and increased amount of cables are factors that have made the fault current rise in many parts of the regional grid. Due to this, a review of possible system earthing designs has been desired, to insure a future-or…
Building integrated PV system sizing based on techno-economics evaluation: Design study for a Southern Norwegian house
2021
Master's thesis in Renewable energy (ENE500) Renewable energy sources are promising to take a significant share in the energy sector as a viable option for integrating with conventional fossil fuel power plants. This thesis contributes to the ongoing studies about building integrated photovoltaic (BIPV) system energy storage. The system comprises the photovoltaic array to capture solar energy, a power converter to change over AC and DC, a grid connection, and a lead-acid battery to store energy. The modeling is also completed by assessing the required load, specifications and choosing the components associated with the system. The geographic area, solar irradiance, and load consumption upon…
Investigation of Outdoor Performance of Silicon Photovoltaic Modules at Different Installation Angles
2021
Master's thesis in Renewable energy (ENE500) The objective of this master thesis is to analyse and compare the performance of two different PV technologies mounted at different tilt angles and orientations. The PV modules are installed on the roof of the J5 building in the University of Agder, located in Grimstad, Norway. The analysis was carried out by comparing 13 months of measured data (from March 2020 to March 2021).The technologies assessed are mono crystalline silicon and poly crystalline silicon, mounted at atilt angle of 10◦East/West, 45◦South and 90◦South.
Wind Turbines for the Power Supply for Offshore Fish Farms : A Case Study for the Norwegian West Coast
2017
Master's thesis Renewable Energy ENE500 - University of Agder 2017 In this thesis the power consumption of a fish farm is set in relation to the expected power production from a wind turbine in order to assess the feasibility of this combination. The fish farm, called Rataren, is located in Sør-Trøndelag and hourly data on power consumption is available in the period 1st February 2016 until 31st August 2016, as a result of change in energy source from diesel generators to the onshore power grid. This is one of Norway’s largest fish farms and has 14 cages during the studied period. There are some minor data losses that are removed from the data sets. Wind speed, air and water temperatures at…
Optimization of multi-reservoirpumped-storage hydropower system using differential evolution
2019
Master's thesis Renewable Energy ENE500 - University of Agder 2019 The study has proposed a long-term optimization model of a multi-reservoirpumped-storage hydropower system which is located in the Aust-Agder region.Based on the requirement a pump has been installed at a particular site on the samechannel as of the turbine unit. The purpose of the pump installation is to elevate wa-ter from lower to the upper altitude reservoir during low power demand to avoidthe overflow or flooding. The flow rate and power data provided by the companyis used to do primary computations to calculate the necessary parameters. The datais discrete, therefore to get the variable expressions second-order polynom…
PEM Fuel Cell System : A practical approach for building, testing and controlling a self designed PEMFC stack
2017
Master's thesis Renewable Energy ENE500 - University of Agder 2017 Fuel cells are an effcient way to produce electricity, especially if it is combined with heat pro- duction. If designed to consume hydrogen, like PEMCF, the only byproduct is water in its purest form H2O. This would have a great impact in the endeavors for a cleaner environment in densely populated areas. The potential for this technology is widespread, seeing usage from user electronics to onsite power production for commercial buildings. We believe that this technology will be even more common in the future, and therefore we would like to create a simple, but useful, fuel cell system for educational purpose. An "easily tak…

Optimization of Wind Farm Layout taking Load Constraints into Account
2017
Master's thesis Renewable Energy ENE500 - University of Agder 2017 Optimization of a wind farm layout is of utmost importance due its economical aspect. The primary aim of optimizing layout is to increase the overall energy production. The higher energy production creates more revenue from wind farm during its operational life time. Wind turbines situated within wind farms are subjected to wake losses due to numbers of factors one of such factor is wind disturbance from the wind turbines installed in front. Therefore, the wind turbines will produce less output as compared to front wind turbines facing winds in free stream. Thus, to have an economically feasible performance, it is necessary …
Active Power Filters in Zero Energy Buildings
2017
Master's thesis Renewable Energy ENE500 - University of Agder 2017 With an increasing focus on the environment and moving from fossil to renewable energy, there has and is an increasing interest in zero energy buildings. Zero energy buildings often utilize local intermittent renewable energies such as wind and solar energy, and are going to play an important role in the smart grid development with their distributed generation and energy storage etc. In Southern Norway, the smart village Skarpnes is utilizing building integrated photovoltaic systems and is developed for studying zero energy buildings and its impact on electricity demand and power quality. Power electronic based equipment suc…
