1. Förnyelse med förhinder : Den riksdagspolitiska debatten om omställningen av energisystemet 1980-2010
Sammanfattning : Denna avhandling undersöker hur omställningen av energisystemet har konstruerats i den riksdagspolitiska debatten, med fokus på förnybara energikällor. Utgångspunkten är det riksdagsbeslut som fattades 1980 och som innebar en omställning till förnybara energikällor. Studien bygger på textanalys av framför allt riksdagsprotokoll. LÄS MER
2. Techno-economic analysis and optimization of electrochemical energy storage solutions
Sammanfattning : The need to integrate the rapidly growing share of variable renewable energy sources in the power sector requires solutions that are capable of mitigating the intermittent nature of these sources. They are expected to constitute the backbone of the electricity generation system in the coming years in order to reach ambitious goals in terms of energy security and reduction of environmental impact.

3. Hybrid energy storage systems : Capacity optimization and environmental implication of hybrid energy storage systems in renewable power systems
Sammanfattning : Electricity production contributes a large share of greenhouse gas emissions that lead to climate change. At present, power generation in many parts of the world still heavily depends on fossil fuels. To prevent global warming, the electricity sector is supposed to transition from the current fuel mix to renewable energy sources. LÄS MER
4. Composite Nanostructured Materials for Renewable Energy Applications
Sammanfattning : Diverse sources of energy are becoming increasingly significant in today's world. The most common source of energy today is fossil fuels, such as coal, oil, and gas. While this energy source has many advantages, it also comes with many problems. LÄS MER
5. Dynamic Thermal Rating for Improved Utilization of Wind Farm Export Systems : A Methodology for Improving Load Profile Estimation of Wind Farm Export Transformers
Sammanfattning : The power system components connected to renewable energy sources, such as transformers, are often oversized and conservatively loaded. The design of transformers normally ignores the intermittent nature of the connected renewable energy sources (e.g. solar, wind). LÄS MER
