The need for a more efficient electrical grid has made the Smart grid concept popular in recent years. The aims of this study are to identify the conditions in Sweden for implementing a Smart grid and to analyse the opinions of stakeholders. One finding is that the large capacity of Sweden?s existing electrical grid decreases the immediate need for Smart grid solutions. However, the rapid increase in wind power might push the development of a Smart grid in the coming years.

The initial aim of the roll out of smart electricity meters in Sweden was to allow remote readings of the households? monthly electricity consumption for billing purposes. Since then the transition towards a Smart grid has become a more prioritized matter. In the roll out of next generation smart meters more attention is therefore given to how the Distribution System Operator (DSO) can benefit from the meter through different Smart grid applications. This study uses a qualitative research method to identify three general fields of application and 15 specific concepts corresponding to ways in which the DSO can create added value from the information provided by the smart meter.

The electrical grid needs to be changed in the future in order to manage more distributed and renewable generation and also to make it possible for electricity consumers to be more active and aware of their electricity consumption. This future grid is usually referred to as a Smart grid. With the transition to a Smart grid, new challenges occur. One method to determine those challenges is to perform risk and vulnerability analyses. InStockholm, the new urban district Stockholm Royal Seaport is built.

Distributed, renewable generation-units 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 for electricityconsumers and new actors, ready to enter the market. At the same time, electricutility companies may question the need for some of these upcoming changes, as theyare sometimes expected to lead the development.This paper therefore seeks to investigate the business opportunities related to SmartGrids.

The Island of Öland has one of the best wind climates for land based wind power in Sweden. An objective for the Island is to become self sufficient using electricity from renewable source of energy such as wind. There 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 definition of smart charging is that the charging is done to some extent with an ICT-system, (information and communication technology) that correlates wind electricity generation to the charging of electric vehicles. The purpose is to avoid grid congestions on the sub-sea cable that connects Öland to the mainland because that in turn would curtail wind energy production.

The Smart grid technology has during the last decade been established as a way to create a greater flexibility on the electricity grid that will be needed as the development moves towards an increased share of renewable primary energy sources in the electricity production. One part of the Smart grid technology is the ability to shift loads in time, to adapt to either price or emissions, known as Demand Response. This project, which was conducted at KTH in collaboration with the consulting corporation Capgemini, examines the economic, environmental and social aspects of the Demand Response technology. In the project, three household products are used in a model that derives the potential savings in costs and emissions of CO2e. The results show that the actual savings measured in SEK are small, but that the savings measured in percent can be as high as 20 percent. Reduction of CO2e emissions is slightly lower.

The purpose of the study is to examine how the teachers in second grade use SMART Board and compare two schools.The process I used was qualitative interviews and classrooms observations. Previous studies shows how widely SMART Board is used in classrooms, and this has also been shown in my study. The study shows how differently SMART Board is used in the classrooms, and how important education in the technology of SMART Board is to achieve in the classroom. The final discussion clearly shows similarities and differences in the use of SMART Board in different classrooms and also the teachers? thoughts about SMART Board as a tool.A central aspect in the use of SMART Board shows how important the basic education in SMART Board is.

Where is technology heading? And how will our behaviors towards these new innovations look? This project questions the direction of ?beyond smart? products, through scenarios within our everyday life. The work is both critical and speculative. Speculative in the sense that it is speculating in how a future scenario with ?beyond smart? products would look like.

Electricity production from renewable energy resources such as wind energy and photovoltaics is variable. Integration of these intermittent resources into the electricity system leads 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 household appliances, to provide flexibility that could be used to balance the grid. In aggregate, when applied to many units across the system, large volumes of energy could be made available when needed and this grid flexibility can be used as a product on the electricity regulation market.Despite the potential benefits, the number of demand response bids is currently low.

This report is intended to give an insight in the Network Performance Assessment 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 find theoptimal amount of redundancy versus the costs. Further is the dimensioning of the grid ofinterest. The fictitious grid is based on energy whereas the real grid often is based onsubscribed power and these two principles are compared and analyzed.The difference in the outcome of the model result due to variations in input data of themodel is also discussed in the report..

De senaste åren har marknaden för surfplattor växt massivt samtidigt som Smart-TV?s har kommit fram som en ny produktkategori. Detta arbete är en undersökningen i hur surfplattor tillsammans med Smart-TV kan användas för att skapa en bättre upplevelse för användaren. För detta utvecklades en applikation på en LG Smart TV som sammankopplades med en surfplatta för att visa information om ett pokerspel. Sedan utfördes en undersökning med intervjuer där hybridapplikationen jämfördes gentemot att bara spela på surfplattan.
