Wind power is expanding rapidly in Sweden. Increasing amounts of wind power sets higher requirements on balancing power and grid expansions and would affect the whole Swedish electricity system. The aim of this report is to examine the factors affecting the wind power expansion in Sweden. How many wind power plants projects will obtain building permissions and what costs and revenues can be expected? How much balancing power will be required and does a changing geographical distribution of the wind power plants reduce the need of balancing power?A survey of the county board?s official applications has been made and out of all the applications, corresponding to 80 TWh produced per year, about half of the applications are expected to obtain a permit with a major portion of them located in the north of Sweden.Especially older wind power plants, deriving revenue from Nord pool, find themselves today in a complicated financial situation.

This essay is built upon the thoughts of Joseph S. Nye concerning power, and the different ways of exercising that power. The characteristics of Nye's theories are the thoughts about the second face of power, or what he describes as the soft power. The essay seeks to examine what kind of power the US has been in their work for non-proliferation and democracy promotion in the Middle East. It also seeks to find what it is that makes the US to choose to exercise the specific powers.

International media groups and the freedom of speech are two issues that have been questioned during the last years when large media groups control a large amount of public-oriented information. The masters thesis at hand considers three debates that illuminate Bonniers and AB Mariebergs hereinafter referred to as the Bonnier Media Group positions on the media market. The objective of such a study is to establish in the face of the theory on hegemonia, for example from which factors the media actors deduce their argumentation when discussing the above-mentioned topic and the meaning of such a discussion in our time. The thesis also discusses whether freedom of speech and free opinion are affected by the increasing power of the Bonnier Media Group and if they, as a result, have diminished their own cultural and liberal assets, features that are firmly associated with the company. I conclude that various features have come to change the media market during the last years.

This is a thesis about the American empire. I also focus my work to see if this American empire is declining. The two main questions I ask and want to answer in this thesis are: is America an empire and is it in decline?I first conclude that America has been an empire ever since the end of the Second World War. The sheer military and economic power of the American empire matches and exceeds the ones before them.

Research shows that non-european academics are discriminated in the labor market. The purpose of this study is to examine non- European academics narratives about their Job search process. By applying an intersectional approach, this study aims to demonstrate how the interplay of different aspects such as gender, class and etnicity shape the interviewees experience in swedish labour market. A postcolonial perspective is applied in order to contribute to deeper understanding of the discriminating structures that the interviewees deal with.The analysis shows that colonial conceptions are embedded in the validation system and institutions such as employment service. This mechanism affects the interviewees negatively in their Job search process.

Academic research concerning how to determine the power situation in a supply chain where an investment product supplier is involved did not exist. Therefore new models has been developed that analyses the power relations and maps out the power situation in a supply chain. In the future these models can be applied on similar cases by modifying the included parameters. The new models show that case company FAS should focus on the big producers of garbage bag which are Trioplast, Rullpack and Miljösäck. By strengthen the brand FAS can make more money in these relations.

This thesis paper is based on Ian Manners Normative Power Europe-theory with a focus on EU?s military operation in Somalia. By examining documents from EU institutions in the form of reports concerning EU NAVFOR ? Operation ATALANTA ? EUTM Somalia ? EUCAP NESTOR. This study shows that the Normative Power Europe-theory can get expressed and that the EU continues its normative statements in Somalia. This result is an interesting contribution to the theory of Normative Power Europe witch have gotten a lot of critic about how a military operation should effect and diminish the theory..

Hofstede constructed a culture dimension called Power Distance, measuring the inequality of Power. Germany and Sweden have relatively similar values according to his world-renowned research. But a series of interviews of Swedish entrepreneurs in Germany shows that these perceive a large difference in inequality of power in the two countries. This essay seeks to explain the difference between these subjective-qualitative experiences and the objective-quantitative data of Hofstedes Power Distance Index. We propose that a combination of differences in communication, exercise and visibility of power and formality influence the way Power Distance is perceived.

Our essay is about children's exercise of power, oppression or domination in games or when playing on school grounds with one and other. We thought it would be interesting to look into how children in preschool and up to the fifth grade use power acts respective power plays in leisure-time. During four days we visited two different after-school center and carried out observations of children during the school day and later inside the recreation centers during leisure activities. In order to analyze our empirical material in relation to power, we have used Magnus Hörnqvist (2012) interpretation of Michel Foucault's theory of power - Another Foucault. We have also used Åsa Bartholdsson (2008) thesis about The regular exercise of power regime ? about normality and power in school.

This thesis treats the normative power of the European Union and its affect on Macedonia. The main purpose has been to look closer with the use of the application of Ian Manners theory of normative power on the Macedonian case. The focus will be to answer the following questions: Does the European Union act as a normative power in relation to Macedonia, if so, how are these values diffused? Has there been any effect of the spreading of these values? Based on six interviews and the available material of European Union strategies for the Macedonian membership I have attempted to understand to what extent the European Union?s normative power has had an influence in Macedonia. The result of my analysis is confirmation of the European Union as a normative power in Macedonia and the understanding of the methods of application..

In electricity markets evolving towards liberalisation and internationalisation, green certificates are seen as an important tool to promote production of renewable energy. In a green certificate market producers sell certificates received per unit of electricity generated from renewable energy. Trade in renewability is thereby decoupled from the the physical electricity trade. Tradable green certificates in combination with renewables obligation are implemented or planned in several EU member states. Integration at EU leveland the creation of a common certificate market seem like a possible next step.

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.

With background in the rapidly growing need to find solutions for sustainable energy production and the increasing interest for wind power, this report was written. With take-off point from the wind power plant Big Glenn, which has been built in the harbour of Gothenburg, a model of the adjacent power grid has been created in Simulink/SimPowerSystems. Parameters for the power grid and its components has been provided by Göteborg Energi Nät, that has also been the supplier of measurement data of produced power, the power need from loads in the vicinity, voltage levels, current values and also the variation of power factor at the wind power plant.The SimPowerSystems model has been used to perform simulations of power flow in the grid. These simulated values have then been compared to the measured values to verify the functionality of the model. Further, the model has been used to perform simulations of a grid fault, which causes a voltage drop.

The technological legacy from the early electrification of the Swedish railroads has resulted in a power grid with a lower grid frequency than the national power grid from which it is fed. Energy transfer between these power grids with different frequencies requires substations, adapting the grid frequency for the rail road power grid. For this purpose, a feeding power grid has been built, stretching across the country from Boden in the north to Tälle/Häggvik in the south.Power transfer in the Swedish power grid results in voltage angle differences which increase with increasing loads and transfer distance. These voltage angle differences are transferred from the power feeding substations to the rail road power grid, will in some extent cause loss of energy due to unwanted power flows from north to south.To minimize the losses due to this phenomenon, a power management system called EFS 132 kV has been developed and implemented. The system minimizes the unwanted power flows and controls the desired power flow for a good distribution of loads between the power feeding substations.This thesis investigates the extent of the transmission losses avoided due to the EFS 132 kV that coordinates the idling angles to a common reference point.The results indicate that EFS 132 kV affects the power flow, especially between the northern substations through an improved load distribution.

Orust Kretsloppsakademi is a nonprofit organisation, with a goal of annually generate the same amount of electrical energy that is consumed. Orust is an island on the west coast of Sweden, north of Gothenburg. The population of 15 000 reaches 40 000 during summer, due to the large amount of vacationer. The total electricity demand is 174 GWh a year with a maximum power need of 32 MW. This report presents an analysis for the plausibility of their plan and from a power system stability perspective, the effects on the electrical grid.The conclusion is that the restraints for development of power generation from wind, solar and wave generation, are the power systems capability to transfer power, primarily in the transformers of the grid.
