1. 21. Entering renewable electricity production : An actor perspective

   Författare :Ingrid Mignon; Anna Bergek; Gunnel Sundberg; Harlad Rohracher; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Renewable electricity production; new entrants; energy transition; energy policy; innovation; entrepreneurship; institutional theory; innovation-­adoption; implementation;

   Sammanfattning : Although energy transition is considered one of the main challenges of our time, little attention has traditionally been paid to the actors participating in this transition, such as the producers of renewable electricity. Previous energy policy literature and policy- makers have assumed that these producers are incumbent actors of the current energy system, that is to say, large utilities producing both renewable and fossil-fueled electricity.

3. 22. The impact of wind power variability on the least-cost dispatch of units in the electricity generation system

   Författare :Lisa Göransson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wind power; intermittency; wind-thermal system; variability; cycling costs; electricity generation system; dispatch modeling; variation management;

   Sammanfattning : This thesis investigates the dynamics of electricity generation systems that involve high levels of wind power. Methods to account for wind power variability in electricity-dispatch models are explored, and the impact of wind power variability on the optimal output of the generation units, so as to meet the system load with the lowest possible cost (economic dispatch), is analyzed for several systems, for both regional and European cases.

4. 23. Swedish industrial and energy supply measures in a European system perspective

   Författare :Louise Trygg; Björn G. Karlsson; Thomas B. Johansson; Linköpings universitet; []
   Nyckelord :Deregulated European Electricity market; Industries; Energy suppliers; CO2 emissions; Electricity reduction; European electricity prices; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : A common electricity market in Europe will in all probability lead to a levelling out of the electricity price, which implies that Swedish consumers will face higher electricity prices with a European structure. This new market situation will force industry and energy suppliers to take new essential measures as actors in a deregulated European electricity market. LÄS MER

5. 24. Cost-effective incentives for local electric utilities and industries in co-operation : modelling of technical measures

   Författare :Maria Andersson; Björn Karlsson; Curt Björk; Tomas Kåberger; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy system; System cost; Electricity market; Co-operation; Demand-side management; Energy efficiency;

   Sammanfattning : In the Swedish electricity system there is a great potential for increasing the cost efficiency of the electricity use. However, today the economic incentives, offered for instance by existing electricity rates, are too weak to improve the use of the system. LÄS MER

7. 25. Distributed Resources in a Re-Regulated Market Environment

   Författare :Thomas Ackermann; KTH; []
   Nyckelord :Distributed Generation; Electricity Markets; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : This thesis analyses the value that distributed resources(DR) can contribute to an economically effcient operation of are-regulated electricity market and discusses the relevantchanges in the regulatory framework to allow the appropriatedevelopment of DR whenever DR may increase the economiceffciency of the electricity market. Distributed resources thereby combine two aspects:Distributed generation and demand-side resources. LÄS MER
