Simulating the thermal potential for energy storage in an electric water heater tank
(Master thesis, 2018)This thesis uses a CFD model of an electric water heater tank(EWHT) to investigate the strati cation in the tank during di erent discharge experiments. Strati cation in a tank happens naturally as hot water rises to the ... -
Prognosis of ball bearings with non-characteristic degradation using recurrent neural network
(Master thesis, 2019)Breakdowns in rotary machines are often related to bearing failure. In recentyears many prognostic and diagnostic models of bearings have been developedto prevent unexpected shutdowns. Estimating the remaining useful ... -
Voltage Regulation Assessment in the Distributed Network with Wind Turbines and Photovoltaics Implemented
(Master thesis, 2019)High penetration of Distributed Generators (DGs) in the Distributed Network (DN) could cause undesirable operating conditions. The DN isby conventional means planned, andoperated in a passivemanner, i.e., the ... -
Hydrothermal Liquefaction of Lignin to Produce Bio-crude : Comparative Analysis of the Effects of Feedstock type and Operating Conditionson Bio-crude
(Master thesis, 2019)Lignin is one of the most abundant non-food biomass resources in the world today andseveral attempts are ongoingto harness its huge potential. Due to its rigid structure however, different processes are being experimented ... -
Photovoltaic production for a fixed tilt plane, with different surface azimuth angles. Analyzing system operating conditions and time of day production
(Master thesis, 2019)Photovoltaicsystems for residential household may bea large part of energy production in the future. The electric grid is facing challenges,andphotovoltaicsystems can contribute in the reduction of electricgrid ... -
System design for a solar powered thermal storage – to obtain reduction of demand side power peaks
(Master thesis, 2019)Demand side management is an efficiency tool to manage the consumption of energy. In this thesis a load controller is developedand used to store self-produced renewable energy as hot water in a domestic hot water heater. ... -
