… software tool, SPICA and the more all?purpose software tool, ARISTO. The grid operators at SvK use SPICA to predict the maximum transfer limit at specified sections (in this report the section in concerns is the southern part of Sweden i.e. interface1 4). SPICA is mainly used as …
This thesis concerns how the power quality in the grid is affected by the connection of wind power plants. As things are at present, Fortum Distribution AB has a number of wind turbines and wind parks connected to the own grid. As the pressure on building and connecting …
… Modeland the parameters that is needed in the making of a fictitious grid that represents anoptimal grid. A main goal is to investigate how the construction of a real grid iscompared to the fictitious.One of the key parameters is how redundancy is treated in the model and to …
- Minor Field Study i Namibia
A large part of the Namibian low income population lack access to grid distributed electricity. This mean they are effectively shut out from basic functions such as lighting, information technologies and hygienic food handling. Hence, finding ways of providing affordable …

En studie som undersöker möjligheter och hinder i utvecklingen av det svenska elsystemet
… and more efficient use of electric power,demands a developed electric grid. This grid is often referred to as the ”Smart Grid”. This future electric system rise expectations among actors in the existing electricmarket. International organizations share visions of opportunities …
Påverkan av ett ökat antal elbilar på ett halländskt elnät
The challenges facing low voltage grids are rising as an increasing number of domestic houses transition from fossil fueled heating to electricity based heating. Several environmental goals and visions have the same transition from fossil based power to electricity based power …
… to perform such simulations at regional scales. However, the usage of a grid based on longitudes and latitudes makes this model work poorly in global simulations. The problem with this grid is that the nodes are concentrated near the North and South Poles. Due to this …
… are embedded in one another, allowing calculation of each parameter in each grid cell. The output from the model consists of raster maps for each time step for a pre-defined parameter, or a time series for a parameter at a specified grid cell. The flow network is generated from …
Är smart laddning av elbilar lösningen på ett framtida flaskhalsproblem?
… is currently 55 MW capacity installed on the Island and it is estimated that grid congestion will occasionally occur if more than 135 MW was installed. The aim of this thesis is to investigate he possibilities for load management by smart charging of electric vehicles, EV. The …
en studie av de svenska partierna ur ett Grid-Group perspektiv
… studera partiernas åsikter har dessa även analyserats i enlighet med Grid-Group teorins analysverktyg. Modellen är att betrakta som ett komplement till ?höger- vänsterskalan? och fokuserar på att fastslå partiernas organisationsstrukturer. Resultatet analyseras avslutningsvis …
The effects from a planned wind farm on the grid utility Gävle Energis electrical grid have been studied. The wind farm is planned to be built in the forest 15 km north of Gävle and will have 23 turbines with rated power from 2 to 2.5 MW, resulting in a total installed power …
During the period 2009-2013, investments in the Swedish national grid increase by a factor of ten compared to previous years. In order to fulfil their mission to manage the national grid in a safe, efficient and environmentally sound way, Svenska Kraftnät (Swedish National Grid) …
En studie ur konkursförvaltares perspektiv med stöd av repertory grid -
… metoden bygger på data från tingsrätten i Luleå samt data utifrån repertory grid. Den kvantitativa datan från analysprogrammet, Repertory grid, bidrar med en principalkomponentanalys samt faktoranalys. Med hjälp av principalkomponentanalysen kunde fyra olika typologier av …
