Identifiering av för- och nackdelar med nätstationsmätning, Mälarenergi Elnät AB
Today’s electrical grid companies understand that better knowledge of and information about their grid can help realize a smart grid network. One way to gain better knowledge and information about the low voltage network is to install measuring equipment on the substation …
… to new challenges in how to manage imbalance between supply and demand on the grid. One way to meet these challenges is to develop so-called smart grid solutions. One idea, called demand response, is to adjust the amount or timing of energy consumption, e.g. by control of …

… generation, is something that has become more and more popular in the electric grid. Microproduction can however lead to unacceptable performance if several units are installed in the same low voltage network. It is therefore good to know a limit where the performance of the low …
… to foresee an upcoming collapse is vital to maintain stable operation of the grid. The grid operator at Svenska Kraftnät (SvK) uses the computer program SPICA to predict the maximum transfer limit at specified transfer sections. SPICA uses actual states from the grid to predict …
Studie av några lärarstudenters uppfattning med Repertory Grid Technique
I studien har en relativt ovanlig intervjumetod, Repertory Grid Technology använts för att ge några blivande fysiklärares syn på god fysikundervisning. Metoden inspirerar till användning i många andra sammanhang. Resultaten visar att god fysikundervisning bland annat uppfattas …
En undersökning i Stockholm
… utgå ifrån; ”Fiedlers Contingency theory” och Robert Blake och Jane Moutons ”Grid-modell.” En deduktiv ansats har tillämpats där teorierna som ansågs vara relevanta för studien har definierats och därefter applicerats på empirin. På fem av Stockholms Clas Ohlson-butiker gjordes …
… Sverige AB started the project KRAFTTAG, were 17,000 km of the airborne power grid shall be replaced with cables underground. The transformers in the airborne power grid shall be dismounted, renovated if necessary and then conveyed to stations, of type kiosk. Additional new …
… syfte var att undersöka möjligheterna att använda intervjutekniken Repertory Grid Technique (RGT) som utvärderingsteknik för att utvärdera User Experience (UX) på distans. Detta gjordes genom att de föreställningar som en handledarstödd utvärdering resulterade i jämfördes med …
… This will of course put a strain for the town’s energy distribution grid. This is a work about trying to predict the grids power usage would be for the next five years if the city building plan is finalized. Those predictions are mainly going to be done through calculations with …
… to establish and maintain a virtual fence around the mobile device. A grid-based algorithm was selected because it can handle small to very large areas. All data are collected in a table which makes the algorithm fast, regardless the size of the area. A grid enables management …

Sweden has a natural gas grid extending along the west coast, from Trelleborg to Stenungsund. There are also several smaller local networks where a planned natural gas pipeline from Skutskär to Hofors prompted the need for a comprehensive study. This study examines the linkages …
… completely climate neutral. As a part of this, one target is to reduce their grid losses by 4 % of the 2012 level, which corresponds to an overall reduction of the grid losses of just over 1.7 GWh. In many residential areas, the distribution grid is designed and rated for …
