Organisering og intern prissetting i Agder Energi Tjenester AS
2003
Hovedoppgave i Industriell økonomi og informasjonsledelse, Høgskolen i Agder, Grimstad Et karakteristisk trekk ved den økonomiske utviklingen de senere årene er den økte fokuseringen på lønnsomhet. Oppdelingen av foretaket i selvstendige ansvarsenheter og desentralisering av resultatansvaret, har vært viktige elementer i en strategi for økt lønnsomhet. Fordi dette motiverer hele organisasjonen til økt lønnsomhet, og fordi det gir bedre muligheter til å identifisere hvilke områder foretaket taper og tjener penger på. Dette gjelder også for energisektoren. I denne oppgaven har vi tatt for oss AET, som er et datterselskap i AE. AET leverer støttetjenester til AE. Oppgaven har som mål å drøfte …
A Magnetostrictive Electric Power Generator for energy harvesting from traffic: Design and experimental verification
2015
In the last decades, the growth in energy demand, the decrease of fossil fuels available in the market and the impact of anthropogenic factors on climate change has given new impulse to research on renewable energy systems, particularly those known as energy harvesting devices (EHDs) [1]. A large number of EHDs have been proposed, using different operating principle [1-4]. Among them, piezoelectric and magnetostrictive seem to be particularly suitable for the application in EHD. In these materials the application of external mechanical stress induces a change in the level of magnetization and therefore an electromotive force (emf) can be generated and collected in order to produce electrica…

Optimal reconfiguration of weakly meshed distribution systems
2011
In this paper the problem of optimal reconfiguration for weakly meshed systems is dealt with; meshes are created by the presence of Favoured Customers (FC) requiring supply through two different paths in order to guarantee the maximum service continuity. Aim of the reconfiguration is to attain a network that operates with minimum power losses, and in order to account for particular needs of the FC loads, that shows the minimum overall yearly fault rate on the branches where the power required by the loads flows. Moreover the constraints concerning the bus voltage profiles, the current in branches and the power balance among HV/MV transformers supplying the network must be full-filled. Due t…
Potential for Usage of Thermoelectric Generators on Ships
2010
Published version of an article from the journal: Journal of Electronic Materials. he original publication is available at Springerlink. http://dx.doi.org/10.1007/s11664-010-1189-1 The useful waste heat potential for a bulk carrier has been evaluated as a preliminary step towards developing a thermoelectric generator (TEG) waste heat recovery system for ships. A medium-sized bulk carrier produces 6.2 MW of waste heat, and the most promising usable sources for the TEG are shown herein to be the exhausts from the main engine and the sludge oil incinerator.
A Pattern Recognition Approach for Peak Prediction of Electrical Consumption
2014
Predicting and mitigating demand peaks in electrical networks has become a prevalent research topic. Demand peaks pose a particular challenge to energy companies because these are difficult to foresee and require the net to support abnormally high consumption levels. In smart energy grids, time-differentiated pricing policies that increase the energy cost for the consumers during peak periods, and load balancing are examples of simple techniques for peak regulation. In this paper, we tackle the task of predicting power peaks prior to their actual occurrence in the context of a pilot Norwegian smart grid network.
